From autonomous vehicles and robotics to sports and healthcare, we're solving AI's hardest problem: turning complex, real-world data into production-ready intelligent systems.\nWe're a team of founders, scientists, quants, researchers, and former Olympians, who’ve helped build some of the most successful companies in Silicon Valley, and alumni of MIT, Stanford, UC Berkeley, Oxford, Cambridge, and Imperial. We’ve raised $110M from legendary technology investors, early backers of companies like Databricks, ElevenLabs and Vercel, and we’re growing at an extraordinary pace.\nWe're looking for exceptional people who want to help build a category-defining company, operating with high urgency and taking real ownership to help shape the future of AI.\nQuant Developer in AI\nYou're a quant developer. You've built high-performance systems that process billions of events per day in real-time, and you care deeply about consistency, correctness and performance. Now you want to build in AI\nThis is your chance. Encord is a scale-up serving the frontier of physical AI and robotics, the largest technological revolution in history, where what you build ships fast and you own it. Help us build the AI data platform for the future of robotics.\nThe role\nYou know how to build systems that are fast and correct under pressure. The hardest problems in AI right now are data problems: distributed, data-intensive systems that have to stay correct and performant at scale.\nYou will join the Foundations team, who build the data systems that enable frontier robotics labs to generate, understand, train, and test on massive volumes of robotics data. We don’t just react to an order book tick - you will need to handle large 3D scenes, hour-long videos, LIDAR point clouds, and ML inference, all under tight performance and operational budgets.\nWhy now? A year ago we were a team of 100; now we're over 180 and still accelerating. You'll work directly with a high-bar team, take on high-stakes problems, and help shape where the platform goes next.\nWhat you'll do\nDesign, build, deploy and own data systems processing petabytes of data across billions of items, from design and architectural decisions all the way to deployment, monitoring and measuring impact\n\nBuild robust distributed systems and reason carefully about how they fail and how they behave under load\n\nDesign performant protocols and APIs, and tackle complex domains and immense scale with correct and pragmatic solutions, moving extremely fast while maintaining engineering quality.\n\nBuild as part of a high-performing team, contribute your knowledge and experience to others.\n\nWho you are\nYou have personally developed and maintained systems from scratch, and know what trade-offs are involved in building reliable, performant software at speed. You will have excelled at something demanding, and can show that your good technical decisions day after day compounded into a competitive edge.\n\nYou may not have AI or ML experience, and that's fine: you are an incredibly fast and curious learner. You can pick up a new topic and quickly become an expert by being ego-less in asking the right questions, and rigorous in performing experiments that propel you up the learning curve.\n\nYou excel under pressure and uncertainty. You don’t let up the pace, you attack the heart of the problem, and you repeatedly make the right tradeoffs.\n\nYou deeply care about the systems you build. You take pride in having thought through the failure modes, shipping readable, bulletproof code, and delivering today instead of next week.\n\nYou enjoy being a member of a high-performing team. You contribute your best work and help others contribute their best. You'll always lend a helping hand when needed and level up those around you.\n\nExperience requirements\n1-5+ years building and operating serious institutional-scale systems.\n\nFluency in Python or Typescript and a deep understanding of a least one of Rust, C++, Java or Golang.\n\nSolid core CS knowledge in data structures and algorithms, distributed systems concepts (databases, replication, partitioning, queuing, caching) and how they behave under load\n\nExperience owning services in production and improving quality through code reviews, testing, rollout and monitoring\n\nExperience at a trading firm, market maker, hedge fund or exchange is a plus: trading systems, market data pipelines, tick or time-series stores, risk engines, ML/QR research pipelines, are all relevant to what we build. Experience with large data migrations or re-architecture projects is a plus.\n\nWhy Encord\nCompetitive salary, commission, and meaningful equity in a high-growth startup\n\nClear, accelerated growth opportunities as the company scales rapidly\n\nStrong in-person culture: 4 days/week\n\nDaily team lunches & dinners\n\nAnnual learning & development budget\n\nComprehensive health, dental, and vision coverage\n\nUS employees: 18 paid vacation days plus US public holidays\n\nUK employees: 25 paid vacation days plus UK public holidays\n\nFrequent travel opportunities across the U.S., London, and Europe\n\nBi-annual company offsites & monthly socials\n\nOperating principles\nHigh agency\nYou see something broken, you fix it or find the person who can. We celebrate the people who solve 90% of a problem before anyone asks.\nBuild with care & urgency\nWe bear-hug the customer. Former founders and people from fast-moving, high-stakes environments thrive here.\nSelf-aware & hungry\nWe stay warm, self-aware, and genuinely hungry. We elevate our peers, and ego doesn't last long.\nInvent in real time\nWe move toward the ambiguity. We’re pragmatic, resourceful, energized by the fact that there's no playbook.\nIf you're looking to do the most meaningful work of your career alongside people who push you to be better, we'd love to meet you.","description_format":"text","description_chars":6076,"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":["Equity","Growth opportunities"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["MLOps","AI Training Data & Annotation"],"lifecycle":[{"event":"open","at":"2026-11-05T11:32:21Z"}],"visa":[],"liveness":{"score":79,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.881,"p_room":0.9,"age_days":36,"expected_fill_days":69,"reasons":["conf:0","velocity","win:mid"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/encord-quant-developer-in-ai","json_url":"https://alion.io/job/encord-quant-developer-in-ai.json","meta":{"generated_at":"2026-11-07T11:50:23Z","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":12483,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":557},"rest":"https://alion.io/mcp/rest/get_company?id=557"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fencord-quant-developer-in-ai"},{"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%2Fencord-quant-developer-in-ai"},{"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%2Fencord-quant-developer-in-ai"},{"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/encord-quant-developer-in-ai\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fencord-quant-developer-in-ai"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3801161}},{"tool":"search_jobs","arguments":{"company":"encord.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3801161},"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.
