No detail is too small. Trust depends on it.\nWe’re a global team building products people can actually use, turning complex technology into something simple and reliable.\nWe stay aligned, move quickly, and think long term, while keeping teams lean and focused on impact.\nAbout the Role\nWe're hiring a Principal Backend Engineer to lead the engineering team behind Push, Aave Labs' regulated, non-custodial on-ramp and off-ramp.\nThis is a hands-on technical leadership role spanning the systems that connect banking and open-banking partners, identity and compliance controls, payment processing, blockchain settlement, customer wallets, and the applications through which customers access Push.\nYou'll set the technical direction for a high-stakes financial product where correctness, security, auditability, and operational resilience directly affect customer funds and regulatory obligations. Alongside designing and building critical systems, you'll provide day-to-day leadership to the engineering team, create clarity from product and regulatory requirements, and ensure the team can deliver safely at pace.\nHow you can make an impact:\nOwn the technical direction and architecture for Push across backend services, external integrations, data flows, and onchain settlement\nTranslate product, regulatory, and operational requirements into a clear engineering roadmap, well-scoped projects, and sound technical decisions\nDesign and build resilient services for on-ramp and off-ramp transaction lifecycles, including payment initiation, status tracking, settlement, exception handling, and customer notifications\nLead integrations with open-banking, payments, identity, compliance, and blockchain infrastructure providers\nDefine secure boundaries between fiat systems, non-custodial wallets, and onchain execution, ensuring sensitive data, permissions, and signing-related flows are handled appropriately\nSet and uphold standards for secure development, architecture review, testing, observability, incident response, deployment, and sustainable on-call ownership\nPartner closely with Product, Compliance, Legal, Security, Operations, Finance, and application engineers\nRemain hands-on in the codebase, particularly for complex architecture, high-risk changes, and critical production issues\nLet's connect if you have:\n8+ years of backend engineering experience, including senior technical leadership of production systems and teams\nExperience designing distributed, event-driven systems that move or account for real money, with a strong understanding of failure modes and operational risk\nExperience with regulated financial products and understanding how to balance compliance and regulatory requirements with product features and goals \nStrong backend programming skills. Production experience with Rust is highly desirable; deep experience with Go, Java, C++ can substitute\nStrong knowledge of API design, PostgreSQL or another relational database, messaging systems, and service-to-service integration patterns\nExperience in regulated fintech, payments, banking, digital assets, or another environment requiring auditability, controls, and high availability\nExcellent system-design judgement, including migration strategy, build-versus-buy decisions, security boundaries, and the long-term operational cost of architecture choices\nA track record of leading engineers through ambiguous, high-impact work while remaining close to implementation and production operations","description_format":"text","description_chars":4055,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Cryptocurrencies","DeFi"],"lifecycle":[{"event":"open","at":"2026-09-12T08:38:12Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-10-31T06:23:40+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":71,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.784,"p_room":0.9,"age_days":52,"expected_fill_days":79,"reasons":["conf:2","win:mid"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/aave-principal-backend-engineer-push","json_url":"https://alion.io/job/aave-principal-backend-engineer-push.json","meta":{"generated_at":"2026-11-02T05:26:55Z","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":7839,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":38},"rest":"https://alion.io/mcp/rest/get_company?id=38"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Faave-principal-backend-engineer-push"},{"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%2Faave-principal-backend-engineer-push"},{"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%2Faave-principal-backend-engineer-push"},{"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/aave-principal-backend-engineer-push\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Faave-principal-backend-engineer-push"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":802662}},{"tool":"search_jobs","arguments":{"company":"aave.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":802662},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
