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.\nTrusted 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.\nThe Role\nTake 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.\nYou 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.\nWhat You Will Do\nIdentify developer or infrastructure problems that could justify a new blockchain capability or product, working with engineering, Product, and customer-facing teams.\n\nDefine each experiment’s hypothesis, success criteria, constraints, and time limit before building.\n\nPrototype across the layers the problem requires: blockchain clients, RPC, indexing, transaction infrastructure, backend services, or smart contracts.\n\nRead protocol specifications and implementation code, then test assumptions with reproducible benchmarks and failure cases.\n\nEvaluate developer or operational value alongside technical feasibility, security, operating cost, and the effort required to support the system.\n\nTake validated ideas through production design, testing, rollout, observability, and operational documentation with partner teams.\n\nWrite concise recommendations to continue, change direction, or stop, supported by the experiment’s results.\n\nParticipate in production support and incident response for the systems you ship. Own monitoring, runbooks, and fixes after launch.\n\nWhat We Are Looking For\nA track record of taking ambiguous engineering problems through working prototypes and production delivery.\n\nDeep hands-on knowledge of at least one blockchain: its execution model, transaction lifecycle, state, finality, and failure behavior.\n\nStrong software engineering skills and experience building backend or distributed systems.\n\nThe ability to read unfamiliar code and specifications, form a testable hypothesis, and design an experiment that can disprove it.\n\nExperience designing reproducible performance benchmarks and using profiling to distinguish CPU, memory, storage, and network bottlenecks.\n\nEvidence of careful reasoning about correctness and security, especially where mistakes affect funds or chain state.\n\nProduct judgment: explain who needs a capability, what it improves, and whether the result warrants further investment.\n\nClear collaboration and documentation so another team can operate or extend what you build.\n\nHelpful Experience\nContributions to blockchain clients, protocol implementations, or open-source infrastructure.\n\nRust, Go, C++, or other systems programming languages; smart-contract development where relevant.\n\nEVM implementation, CPU microarchitecture, compiler optimization, or hardware performance counters.\n\nRPC performance, transaction submission, simulation, indexing, or cross-chain infrastructure.\n\nEarly-stage products where you helped decide what to build and what to stop.\n\nWhat Success Looks Like\nWithin six months:\nYou have completed a scoped experiment and documented a decision to continue, redirect, or stop it, citing the results.\n\nFor 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.\n\nBenefits & Perks\n Private Health Insurance\nGym Reimbursement\nCommuter Benefits\nFlexible Time Off\nIn-Office Group Meals\nLearning & Development Stipend\nCompany Sponsored Conferences & Events\nBooks & Audiobook subscription with Bookster","description_format":"text","description_chars":4309,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Flexible time off","Health insurance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto","Web3 & dApps","Blockchain Infrastructure","Developer Tools"],"lifecycle":[{"event":"open","at":"2026-10-13T18:44:27Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":154,"reasons":["conf:4","win:early"],"computed_at":"2026-10-14T06:34:16Z"},"pay":{"stated_usd_annual":230000,"is_top_pay":true},"html_url":"https://alion.io/job/alchemy-senior-blockchain-engineer-moonshot","json_url":"https://alion.io/job/alchemy-senior-blockchain-engineer-moonshot.json","meta":{"generated_at":"2026-10-14T12:56:20Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":15808,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":1292},"rest":"https://alion.io/mcp/rest/get_company?id=1292"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Falchemy-senior-blockchain-engineer-moonshot"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Falchemy-senior-blockchain-engineer-moonshot"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Falchemy-senior-blockchain-engineer-moonshot"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/alchemy-senior-blockchain-engineer-moonshot\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Falchemy-senior-blockchain-engineer-moonshot"}]}
