About Alchemy Alchemy is the Web3 infrastructure and developer platform that powers millions of users and the world’s most innovative blockchain applications. From enabling $1+ trillion in financial transactions worldwide to scaling L2s and enabling DeFi, Alchemy provides the infrastructure and tools developers need to build reliable, scalable, and accessible experiences. Trusted by companies like JPMorgan, Stripe, Visa, Franklin Templeton, Nike, and backed by a16z, Coatue, Silver Lake, Lightspeed, and Stanford University, Alchemy is building the foundational layer for a decentralized and AI-enabled Web3 ecosystem. For more information, visit alchemy.com . The Role Take new blockchain infrastructure and product ideas from an uncertain problem to a working system. You will help choose what to test, build the smallest experiment that answers the important questions, and turn promising results into production software. You should enjoy reading protocol specifications and unfamiliar code, talking to developers, and building enough to find out whether an idea is useful. You are also willing to stop an experiment when the evidence does not support it. What You Will Do - Identify developer or infrastructure problems that could justify a new blockchain capability or product, working with engineering, Product, and customer-facing teams. - Define each experiment’s hypothesis, success criteria, constraints, and time limit before building. - Prototype across the layers the problem requires: blockchain clients, RPC, indexing, transaction infrastructure, backend services, or smart contracts. - Read protocol specifications and implementation code, then test assumptions with reproducible benchmarks and failure cases. - Evaluate developer or operational value alongside technical feasibility, security, operating cost, and the effort required to support the system. - Take validated ideas through production design, testing, rollout, observability, and operational documentation with partner teams. - Write concise recommendations to continue, change direction, or stop, supported by the experiment’s results. - Participate in production support and incident response for the systems you ship. Own monitoring, runbooks, and fixes after launch. What We Are Looking For - A track record of taking ambiguous engineering problems through working prototypes and production delivery. - Deep hands-on knowledge of at least one blockchain: its execution model, transaction lifecycle, state, finality, and failure behavior. - Strong software engineering skills and experience building backend or distributed systems. - The ability to read unfamiliar code and specifications, form a testable hypothesis, and design an experiment that can disprove it. - Experience designing reproducible performance benchmarks and using profiling to distinguish CPU, memory, storage, and network bottlenecks. - Evidence of careful reasoning about correctness and security, especially where mistakes affect funds or chain state. - Product judgment: explain who needs a capability, what it improves, and whether the result warrants further investment. - Clear collaboration and documentation so another team can operate or extend what you build. Helpful Experience - Contributions to blockchain clients, protocol implementations, or open-source infrastructure. - Rust, Go, C++, or other systems programming languages; smart-contract development where relevant. - EVM implementation, CPU microarchitecture, compiler optimization, or hardware performance counters. - RPC performance, transaction submission, simulation, indexing, or cross-chain infrastructure. - Early-stage products where you helped decide what to build and what to stop. What Success Looks Like Within six months: - You have completed a scoped experiment and documented a decision to continue, redirect, or stop it, citing the results. - For a bet that proceeds, you have validated a developer or infrastructure use case, delivered a production pilot with correctness checks and a rollback plan, and taken responsibility for its production support.

Chief of Staff for Engineering

Negotiable

Chief of Staff for Engineering About Us Parity is one of the world's most experienced companies building the core infrastructure behind blockchain - the system that allows information and value to be shared securely without needing an intermediary. We're laying the foundation for a better web which respects the freedom and data of individuals, and empowers developers to build better, more trustworthy online services. Our remote-first, global team develop open-source software that anyone can use or improve. This includes Polkadot https://polkadot.network/, Polkadot SDK https://substrate.io/, and Kusama https://kusama.network/ — key parts of the Web3 tech stack, the next generation of the internet.Our mission is to make Polkadot the most active and innovative community in blockchain, powering a new era of connected and decentralised applications. About the Team This role sits at the heart of Parity's leadership, working directly with our Founder to drive organisational alignment and execution across the company. About the Role You will work directly with Gavin Wood, Parity's Founder. Your job is to take his vision, goals and ideas, and turn them into clear decisions, aligned teams, and forward momentum. You will think 12 to 24 months ahead, not just manage what is on fire today. You understand that the decisions made now impact the future, and you treat them accordingly. You will be a key partner to Directors across the business, our CEO, and the primary bridge between Gavin's priorities and the Acceleration team's execution. What You'll Do - Operate as Founder's technical right hand. You will manage his context, his priorities, and his follow-through. You are available when it matters. You anticipate what he needs before he asks for it. - Turn chaos into clarity. Parity moves fast. You will work in an environment of competing half-thoughts, ambiguous mandates, and shifting priorities. Your job is to impose structure without killing momentum, and to spot the counterproductive plays before they cause damage. - Think long. You will not just solve today's problem. You will map the second- and third-order consequences of decisions being made now and make sure the right people are thinking about them. - Lead cross-functional problem solving. When something falls between departments, you pick it up. You have the technical credibility to engage with engineering leadership and the operational instinct to get things moving. - Own the leadership rhythm. OKRs, technical reviews, decision-making cadences, you design and run the operating system for Gavin's leadership team. - Manage up, across, and down. You will work with C-Level and Directors across different Functions of the business. Each is different. You will adapt your communication style to each of them without losing your own voice. Your Skills - Technically credible. You have a background in engineering or engineering management. You can hold your own with a CTO, challenge timelines credibly, and evaluate the viability of new technical initiatives. You do not need to be a Blockchain Engineer, but you understand the ecosystem well enough to distinguish substance from hype. - A sophisticated operator. You have run complex, cross-functional programmes at a senior level, ideally having led a team or founded a company. You know how to create clarity from ambiguity, manage without authority, and drive decisions in organisations that do not move in straight lines. Experience managing leaders, including more junior managers, is a strong signal. - Exceptional communicator. Not just clear, adaptive. You can shift registers between a demanding Founder, Functions Leads, and a junior team member. You know what each person needs to hear and how they need to hear it. - A long-term thinker. You are not a damage limitation operator. You think about what the decisions being made today mean in 12 to 24 months. You bring that perspective into rooms where others are only looking at this quarter. - Believes in Web3. You do not need deep protocol experience. But you need to understand why this technology matters and be genuinely curious about where it is going. Candidates who are indifferent to the mission do not last here. - Thrives in ambiguity. Parity is not a machine. It is a high-conviction, fast-moving organisation with a demanding founder. You find that energising, not exhausting. - Academically strong. A high-calibre degree matters. If you have one, lead with it. If you don't, your track record needs to be exceptional. About Working With Us Joining Parity means joining teammates who are genuinely excited about the impact their projects are having, and the opportunity to grow alongside some of the brightest minds in the Web3 space! You’ll work remotely and flexibly, while still getting to meet your teammates throughout the year at team and company-wide retreats. Upon receiving an offer, all candidates undergo a background check through Zinc https://zincwork.com/candidates, our trusted third-party provider. Team members will be taken on as a contractor via our UK entity. View our Applicant Notice https://www.parity.io/applicant-notice/ to see how we use your data. Parity is an Equal Opportunity Employer. We welcome diversity in our global team and care about everyone in our collective feeling included and welcome Is this position not quite your match?

Software Engineer - Smart Contract, Bridge

Negotiable

Who we are About Bridge We're creating an entirely new payments platform, built with stablecoins, to simplify global money movement. Bridge enables faster, cheaper payments and borderless access to dollars via stablecoins. Through our APIs, businesses can send and receive funds across borders faster and cheaper vs. SWIFT and other fiat-only rails. Our virtual accounts enable international consumers and businesses to easily access, store, and spend US dollars. Our payouts infrastructure enables platforms to disburse USD to anyone globally. We believe many trillions of dollars will move and settle through stablecoin payment rails. Bridge is pulling this future forward. We have a small team of people who have previously built financial infrastructure at some of the world's leading companies (Coinbase, Stripe, Square, Brex, Upstart, DoorDash, Airbnb), and each and every one of them chose Bridge because they fundamentally believe that stablecoins will be a critical piece of financial infrastructure that allows for the improvement of global money movement. About the Role As one of the first blockchain engineers at Bridge, you'll have the autonomy to work on projects that are truly global in scale and aim to give customers access to products they've never had access to. Many of the use cases that we work on today didn't exist several months ago, and that's because our team is dedicated to constant improvement for our partners and end users. Our engineers have outsized ownership over projects, so if you're looking for increased autonomy working on a completely greenfield opportunity, Bridge is the place for you. Responsibilities • Build out multi-chain hot wallet infrastructure to support increased reliability of our payments. • Build smart contracts to increase hot wallet payment throughput. • Build smart contract platform to issue custom stablecoins across multiple blockchains (EVM, Solana, Stellar, etc.). • Build smart contract monitoring systems to detect anomalous events (especially related to minting and burning). • Design and develop blockchain-based applications and protocols to support stablecoin transactions and integrations. • Collaborate with cross-functional teams to understand business requirements and translate them into technical specifications. • Implement and maintain smart contracts, ensuring security and efficiency. • Perform thorough testing and debugging of blockchain applications. • Optimize blockchain performance and scalability. • Stay up-to-date with the latest developments in blockchain technology and integrate relevant advancements into our solutions. • Provide technical guidance and support to other team members. • Contribute to the overall architecture and design of our blockchain systems. Who you are We're looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply. The preferred qualifications are a bonus, not a requirement. Minimum Requirements • Bachelor's or Master's degree in Computer Science, Engineering, or a related field • We're open to hiring engineers at various levels of seniority, but in general we'd look for somebody with 5+ years of experience • Strong proficiency in blockchain platforms such as Ethereum, Solana, or others • Experience with smart contract development using Solidity or other relevant languages • Deep understanding of cryptographic principle
