alchemy - Senior Blockchain Engineer, Moonshot
Requirements
• 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. • 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.
Responsibilities
• 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.
