Interested in working on cutting-edge blockchain technology and creating equitable access to the global financial system? Since 2014, the mission-driven team at the Stellar Development Foundation (SDF) has helped fuel the tremendous growth of the Stellar blockchain network, an open-source platform that operates at high-scale today. Developers and companies around the world build on it, and the SDF team is expanding to support the rapidly growing and changing Stellar ecosystem. About the Project & Team: At the SDF, a small team of roughly 8 engineers is incubating a novel distributed systems prototype. Not a blockchain as you know it, something new. This is a rare opportunity for a zero-to-one build where much of the infrastructure and tooling does not exist yet. You will be building it. To be clear: this is not a maintenance role for our existing network, nor is it an academic research project. We are actively building a high-performance platform designed to handle real value. We operate as a fast-moving, highly technical team with no layers of management. You will work directly with the protocol architect and core systems engineers to take this completely greenfield project to production. If you thrive on the urgency of a new launch and want the agility of an early-stage startup with the stability of SDF, this is the place to be. About the Role: We need a Backend/Systems Engineer who owns the critical layer between our core infrastructure and the outside world. The public API, indexing, data pipelines, and everything that makes the system usable by developers and partners. Today, nobody owns this layer end-to-end. Pieces exist, but the JSON-RPC endpoint, transaction status tracking, analytics pipelines, and data services are a greenfield waiting for an owner. This role benefits enormously from someone who has already been through a complex infrastructure launch (like a testnet or mainnet). You know what breaks, what gets skipped and regretted later, and what "production-grade" actually means for infrastructure that handles real value. What the First Few Months Look Like: - Month 1: Understand the system architecture end-to-end. Get the full stack running locally. Own the JSON-RPC spec and start building. - Month 2-3: Working RPC endpoint. Submit a transaction, query its status, check a balance. Indexer serving the block explorer. Transaction lifecycle fully instrumented. - Beyond: Data pipelines, partner integrations, API hardening, load testing. Bake in the production readiness that comes from having done this before. In this role, you will: - Public API Layer: Design and build the JSON-RPC endpoints that external tools, SDKs, and wallets use to communicate with the core network (transaction submission, status queries, account state). - Transaction Lifecycle: Own the full path from client to consensus and back. Status tracking, error reporting, and timeout handling. - Indexer & Query Backend: Build the data backend that powers the block explorer, partner integrations, and historical state queries. - Data & Observability: Build out analytics pipelines (e.g., BigQuery population) and implement robust metrics and event logging using tools like Prometheus, Clickhouse, and Sentry. - Cross-Functional Impact: Work across service boundaries, getting comfortable reading code in components you don't own to understand how they behave. You have: - Strong systems or backend programming experience in Rust, C++ or both (our codebase uses both). - Proven track record of designing and building robust RPC/API services that handle real-world, high-scale traffic. - Deep understanding of database architecture, indexing, and query patterns. - You are a builder who takes ownership of production infrastructure, not just prototypes. Bonus Points if: - Prior experience building or operating blockchain infrastructure (nodes, RPC layers, indexers) in production. - Experience with a testnet or mainnet launch. We offer competitive pay with a base salary

Software development is becoming a collaboration between developers and AI systems. Most AI developer tools operate on prompts and static snapshots of code. But real software development happens inside large, evolving codebases that change continuously through edits, refactors, discussions, and collaboration. We are building AI systems that operate inside that environment. Zed today is a code editor built from scratch in Rust with GPU acceleration and real-time multiplayer collaboration. Every keystroke and edit can be shared instantly between collaborators, creating a shared workspace where developers and increasingly AI systems can work together. We are also building DeltaDB https://zed.dev/blog/sequoia-backs-zed, a system that records the operational history of software development. It captures edits, discussions, and AI interactions as they happen. This creates a foundation for AI systems that can reason not just about code, but about how that code evolves over time. Much of this work involves designing systems that help AI understand large, evolving codebases. This includes providing the right context and evaluating whether its suggestions actually improve the software. The work sits at the intersection of AI systems, developer tools, and distributed collaboration. We are exploring how software gets built when AI becomes part of the development environment itself. SOME QUESTIONS WE ARE EXPLORING Many of these questions do not yet have established answers. Part of the work is designing and testing new approaches in real developer workflows. - How should AI reason about codebases that are constantly evolving rather than static repositories? - How can streams of development activity such as edits, refactors, and discussions provide useful context for models? - What does it mean for AI to operate inside a real-time collaborative environment where multiple developers are editing the same project? - How should AI systems make suggestions without interrupting developer flow? - How do we evaluate whether AI systems are genuinely helping developers understand and evolve complex software systems? WHAT YOU WILL WORK ON - Designing systems that allow AI to participate directly in developer workflows - Building infrastructure that connects language models with the editor and developer tools - Developing context systems that help models reason about large codebases - Designing evaluation frameworks for AI-assisted development - Improving the reliability, latency, and cost efficiency of AI features - Working closely with editor and infrastructure engineers to ship ideas quickly - Pair programming with teammates to explore ideas and refine systems together REQUIREMENTS - Experience building production systems powered by large language models - Strong understanding of model behavior, prompting, and evaluation - Experience integrating AI capabilities into real software products - Strong backend or systems programming experience - Interest in developer tools and programming environments - Ability to collaborate closely with other engineers - Experience with Rust, or willingness to learn PREFERRED EXPERIENCE - Building AI coding assistants or developer tools - Designing evaluation systems for LLM-driven products - Working with large codebases, compilers, or programming environments - Experience with tool-using or agent-style models - Experience with Rust ABOUT ZED Zed is open source and built in public by the team behind Atom and Tree-sitter. The editor is written in Rust with GPU acceleration for every frame. When you type or move the cursor, pixels respond instantly. That responsiveness keeps you in flow. Zed is multiplayer by default, allowing developers to work together in the same codebase in real time. Much of our work happens through pair programming, with engineers collaborating directly inside the editor. We ship improvements weekly and work closely with a community that cares deeply about the craft of developer tools. Location: Rem

Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution. The company is founder-led, profitable, and growing. Canonical is looking for exceptional security-focused software engineers to be integrated across product teams. While they also contribute to the product as engineers, their primary focus is to challenge the entire team to think more deeply about security through state-of-the-art practices such as threat modeling, table-top exercises, architecture and design reviews, static analysis tools, and fuzzing, among others.&nbsp; These roles encompass all aspects of product security, including feature development, vulnerability response, proactive security, and open source community participation. Engineers in these roles collaborate closely with other Canonical teams, customers, and partners across the open source ecosystem. Each product engineering team at Canonical reserves one or two openings for security-oriented software engineers. We also develop a number of products driven entirely by security needs, such as our AppArmor kernel investments and the Ubuntu Security Guide (USG).&nbsp;As the publisher of Ubuntu, we also handle long-term security response for the entire operating system and open source ecosystem. Working with tens of thousands of upstreams means that we need to be fluent in every major programming language and design, build, and adopt sophisticated tools that enable us to work at scale and speed with confidence.

Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is very widely used in breakthrough enterprise initiatives such as public cloud, data science, AI, engineering innovation and IoT. Our customers include the world's leading public cloud and silicon providers, and industry leaders in many sectors. The company is a pioneer of global distributed collaboration, with 1000+ colleagues in 70+ countries and very few office based roles. Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution. The company is founder led, profitable and growing. We have created a new career path at Canonical for Performance Engineers who bring exceptional clarity to software performance, correctness and efficiency. We are adding these roles to every engineering team at the company. As an open source platform, we have teams that work at every level of the software stack - from the kernel up through server and desktop applications, all the way to the web. We are adding roles with this focus in every engineering team in the company, to act as drivers of performance engineering skills, tools, culture and insights to our entire product range . We have also created a central performance engineering team, where we will drive shared tools, dashboarding capabilities, measurement frameworks, analytical capabilities and skills. We call this career focus ' percorr ' because we have found that the same deep insights that enable sophisticated performance measurement and design also enable teams to improve their harnesses and frameworks for correctness. Understanding not only the application, but the runtime, the compiler, and the system, all the way down to the CPU, gives an engineer the ability to think creatively and with insight about the right things to measure, and the right ways to verify correctness. We have found that performance engineers will often improve the deepest and trickiest areas of our test harnesses, and unblock their teams to test and measure previously 'dark' aspects of their work. We also have teams that work with every major silicon vendor and cloud, with a particular emphasis on performance optimisation of the entire stack for that architecture, CPU family or hypervisor. Our goal is to ensure that Ubuntu users can select whatever platform they want for their workloads and know they have access to the very best performance and efficiency across the entire stack from kernel to codec. If they wish, we will enable performance and correctness engineers to move between products every two years, so that they have the opportunity to raise the bar for performance in an array of products over time, and also that teams have the benefit of fresh eyes on their processes, thinking, harnesses, dashboards and code. Our performance and correctness leads are expected to be truly exceptional individuals, and also leaders who are confident setting expectations of change, sharing insights and skills, running initiatives and programs. There is no way to move a meaningful codebase without also moving the people behind it. This is a career path for perfectionists and precision artists. Whether you have a particular language focus - C, C++, Rust, Golang, Python, Java, Flutter-Dart or others - or a particular love of the kernel or hardware or CPU instruction set, whether you see yourself as driving perceived user experience through performance or optimising the efficiency of data centers to reduce carbon footprint, this process is the best way to find a role at Canonical that speaks to your precision, rigour, insight and drive. <p&g

Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is very widely used in breakthrough enterprise initiatives such as public cloud, data science, AI, engineering innovation, and IoT. Our customers include the world's leading public cloud and silicon providers, and industry leaders in many sectors. The company is a pioneer of global distributed collaboration, with 1200+ colleagues in 75+ countries and very few office-based roles. Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution. The company is founder-led, profitable, and growing. This is a general track for first-level engineering management positions at Canonical. We believe that open source is just starting to transform the tech sector and enterprise compute. Our goal is to make open source easier, more reliable, and more secure for deployment and development. We strive to be the provider of ‘most software to most companies’. To deliver on that ambition, our engineers are carefully selected from the applicants across the globe. We select for brilliance and motivation to take open source to the next level. Our engineering managers help teams achieve more than they realised they could, and feel proud of the result. We believe that Engineering Managers should be outstanding developers themselves. They should be completely at home reviewing a patch or a software design spec. They are trusted engineers who understand the importance of a whole-team effort in creating great products and who enjoy seeing colleagues develop. They should contribute code themselves to set the standard for coding, but know that the code they write is far less significant than their ability to shape the whole team’s direction, focus, and delivery.
