The fact that so many people hate what they do for work is a disaster on so many levels. How many people live quiet lives of misery? How many generational talents do we miss due to circumstance?\nDex’s mission is to close the gap between Talent & Opportunity, we believe that work, and being productive, is part of the human condition, that regardless of AI, human passion, ingenuity and a desire to do things means that work will always exist.\nWe are building Dex to create a future where technology helps every individual to understand their strengths, interests and unique abilities, and to connect with opportunities where they can thrive, because more people doing things they love leads to a better, happier and more productive world.\nWe are starting by connecting the world's most ambitious software engineers with the companies that deserve them.\nThe Role\nThis is a Staff-level full-stack product role with a backend-heavy centre of gravity. You'll own complete product slices end-to-end - things like a candidate database with rich search and filtering, a dashboard that surfaces call transcripts and match history for our Talent Operations team, and the workflows that let them stack-rank candidates against a new role in minutes rather than hours. You ship these without needing to be guided step by step.\nYou're not a specialist who hands off at the API boundary. You think in user outcomes and delivery units, and you're reliable: your code handles edge cases, your APIs have clean contracts, and the work you ship stays shipped.\nWhat You'll Do\nOwn product delivery - take features from spec to production, backend-first but covering frontend and integration where needed\n\nBuild and maintain backend systems - product APIs, data pipelines, and core infrastructure on our Python/FastAPI/Postgres stack\n\nBuild with LLMs and agents - ship product features with significant LLM integration; contribute to the voice agent backend and information extraction systems\n\nWork across the stack - ship workable React/TypeScript frontend for product features; not a frontend specialist, but comfortable and pragmatic\n\nCollaborate with product and design - translate ambiguous requirements into concrete shipped work; be the engineer who unblocks, not the one who waits\n\nMaintain quality at speed - handle data integrity, error paths, API evolution, and operational concerns as a default, not an afterthought\n\nWhat We're Looking For\nLeading teams or entire product lines - You can take responsibility for driving delivery across a team or across an entire product line\n\nSeeing good at scale, and early stage - you've moved fast in scrappy, early-stage environments, and seen what good looks like at scale\n\nIndependent delivery - You can own and ship end-to-end product slices with minimal supervision; your track record shows features that shipped, stuck, and scaled\n\nProduct trade-off judgment - you balance speed, quality, and user impact under ambiguity; you push back when something is underspecified and make pragmatic calls when it needs to ship\n\nReliability and API discipline - you handle data integrity, error paths, idempotence, and API versioning as standard practice; production reliability is your default, not a later concern\n\nCross-functional pragmatism - you work effectively with product and design, can unblock yourself across the stack, and ship workable frontend when that's what's needed\n\nStrong technical depth in:\nPython backend (FastAPI or equivalent, async patterns, Postgres, Redis)\n\nLLM integration - building products where AI is in the critical path, not bolted on\n\nAPI design and data modelling\n\nJavaScript/TypeScript - comfortable enough to ship frontend features and review frontend PRs\n\nNice to Have\nExperience with voice agents or real-time audio pipelines\n\nFamiliarity with evals, guardrails, or agent observability\n\nFamiliarity with GCP / cloud infrastructure\n\nExperience in recruiting tech, marketplaces, or matching systems\n\nThe Stack\nA modern Python stack: FastAPI, Postgres, Redis, Docker, Pydantic AI, running on GCP. Frontend in React/TypeScript. We iterate fast and keep the codebase clean.\nWhat We Offer\nAbove market salary - we're building a world class team and believe pay should match that ambition\n\nSignificant equity - we want this to be the last job you 'have' to take\n\nFull private healthcare & dental - because life happens and we want to support you\n\nFertility benefits & enhanced parental support\n\nGym membership & wellness benefits\n\nClaude tokens - lots and lots of Claude tokens\n\nRegular socials, offsites and an annual trip\n\nMacBook Pro + team kit\n\n\"Whatever you need\" approach to tools and support\n\nInterview process\nWe move quickly and with conviction. Broadly you can expect:\nWe love it when candidates have experimented with our agent, Dex. Even if you aren't an Engineer, you can get a sense of what we're building, and we love to hear your feedback.\n\nA 30m video call with our Internal Talent Lead; we'll share more about the team, role and business before asking questions about your experience and fit.\n\nHiring Manager call: we'll share more specific context on short and medium-term objectives and ask deeper questions relative to the role requirements.\n\nMost roles involve a practical task to better understand how you work. Usually completed offline and reviewed by the team.\n\nOnsite interview loop where you'll visit the office, meet a cohort of the team, one interview centred on the task you produced, another on Dex culture and values, with a final interview with our Founder, Paddy.","description_format":"text","description_chars":5625,"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":["Apple Macbook","Equity","Gym membership"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["DeFi","Crypto Exchanges","Job Boards & Aggregators","HR & Recruiting AI"],"lifecycle":[{"event":"open","at":"2026-11-13T17:41:03Z"}],"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":90,"reasons":["conf:1","win:early"],"computed_at":"2026-11-13T19:12:56Z"},"pay":null,"html_url":"https://alion.io/job/dex-dex-staff-product-engineer","json_url":"https://alion.io/job/dex-dex-staff-product-engineer.json","meta":{"generated_at":"2026-11-13T19:12:56Z","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":38386,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":450364},"rest":"https://alion.io/mcp/rest/get_company?id=450364"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fdex-dex-staff-product-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fdex-dex-staff-product-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fdex-dex-staff-product-engineer"},{"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/dex-dex-staff-product-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fdex-dex-staff-product-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4270535}},{"tool":"search_jobs","arguments":{"company":"meetdex.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4270535},"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.
