We trade 24/7 across some of the fastest-moving, most data-rich venues in finance.\nCrypto is one of the few markets where the gap between a good model and live PnL comes down to how fast and how reliably you can ship it. Abundant data, novel microstructure, and a short path to production mean the quality of our infrastructure directly moves the edge. We're looking for a Quantitative Developer to build that infrastructure and get our models into production.\nThe role\nThis is a hands-on engineering seat on our trading floor. You'll own the infrastructure that turns research models into production trading systems, working primarily in Python and Rust, the language our models and systems are written in. You'll build the frameworks and tooling that let quants ship their code to production and keep those systems running once they're live.\nYou'll work shoulder-to-shoulder with researchers, traders, and fellow engineers, building the tooling, pipelines, and standards that let good ideas reach production quickly and safely, and helping raise the engineering bar across the floor.\nYou will\nBuild and own the infrastructure that takes models from research to production - data pipelines, backtesting, deployment, and monitoring.\n\nTurn research prototypes into robust, performant, production-grade code that runs reliably in live trading\n\nWork closely with quantitative researchers and traders to get new models live quickly and safely\n\nOwn the systems you ship in production: monitor performance, diagnose issues, and keep latency and reliability high\n\nImprove the tools, standards, and pipelines the team relies on, raising the engineering bar across the floor\n\nWhat we're looking for\n2+ years of software engineering experience, with a track record of shipping production-grade systems\n\nA strong academic foundation in a STEM discipline (computer science, mathematics, physics, engineering, or similar)\n\nStrong programming skills in Python and ideally Rust and/or C++.\n\nSolid software engineering fundamentals: clean, testable, maintainable code, version control, testing, and CI/CD\n\nThe ability to collaborate with researchers and traders and translate research code into production systems\n\nClear written and verbal English\n\nStrong Pluses\nExperience building or maintaining trading, backtesting, or data infrastructure\n\nFamiliarity with market microstructure, or an interest in learning how trading systems work end-to-end\n\nWhat's in it for you?\nReal ownership and a direct line to live PnL. Research, engineering, and trading happen a few metres apart, with the shortest feedback loops in the industry.\n\nCompetitive base salary plus a very attractive performance-based bonus tied to individual and company results\n\nFor strong performers, the opportunity to buy into the trading fund\n\nA floor of strong peers and minimal bureaucracy between a good idea and production\n\nAnnual learning & development budget and an in-house training program\n\nPension plan, company laptop, and reimbursement of home internet costs\n\nGym membership reimbursement and sports during working hours (kickboxing, CrossFit, fitness, soccer)\n\nDaily breakfast and warm lunch, with snacks and drinks throughout the day\n\nRegular socials: weekly Friday drinks, monthly outings, quarterly sports competitions, bi-annual trips abroad\n\nFor internationals: an all-in relocation package and Dutch classes\n\nOur culture\nAt our core, we are a team of passionate trading and tech enthusiasts committed to revolutionizing trading through automation. Our collaborative approach ensures that everyone contributes to achieving our ambitious goals.\nIn this role, you will be both challenged and stretched, with ample opportunities for growth and development, both within and beyond your main responsibilities.\nWe invest in our people by offering competitive compensation and benefits, fostering innovation, and celebrating success. Our commitment to personal development transcends traditional norms; we provide an equal playing field, promote reverse leadership, and offer boundless growth opportunities for all our employees.\nJoin us to unlock your potential and drive innovation in the exciting world of algorithmic trading.","description_format":"text","description_chars":4318,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Growth opportunities","Gym membership"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Blockchain & Crypto","Online Brokerage & Trading Platforms"],"lifecycle":[{"event":"open","at":"2026-09-05T06:47:16Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.173,"p_room":0.28,"age_days":118,"expected_fill_days":22,"reasons":["conf:3","stale_co","ghost","win:tail","crowd:junior"],"computed_at":"2026-11-03T05:54:40Z"},"pay":null,"html_url":"https://alion.io/job/blocktech-quantitative-developer","json_url":"https://alion.io/job/blocktech-quantitative-developer.json","meta":{"generated_at":"2026-11-04T00:41:53Z","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":972,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-05T00:00:00Z"}},"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":103220},"rest":"https://alion.io/mcp/rest/get_company?id=103220"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fblocktech-quantitative-developer"},{"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%2Fblocktech-quantitative-developer"},{"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%2Fblocktech-quantitative-developer"},{"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/blocktech-quantitative-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fblocktech-quantitative-developer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":204052}},{"tool":"search_jobs","arguments":{"company":"blocktech.agency","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":204052},"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.
