Specializing in crypto options, we facilitate global cryptocurrency derivatives and spot trading, while expanding into new markets. As we continue to grow rapidly, we are looking for a Senior Software Engineer to take technical ownership of the data infrastructure our trading and technology teams are built on.\nEvery decision at BlockTech starts with data: exchange feeds, our own trade and account events, and the history we query to make sense of both. The Foundation team owns the systems that move, aggregate, and store all of it. We run our own Kafka, NATS, PostgreSQL, ClickHouse, and Iceberg, self-hosted and tuned by us. We work primarily in Rust, with Python and SQL alongside.\nThis is a role for an engineer who has already built and operated data infrastructure at scale, and who wants their technical decisions to set direction rather than follow it.\nWhat will you do?\nYou will own the pipelines and stores every other team depends on. When a researcher backtests a strategy, when a trader checks a position, when risk queries yesterday, they are all reading data your systems ingested, routed, and kept correct. As a senior engineer, you will also set the technical standards the rest of the team builds against.\nYou will:\nOwn the ingest path. Collect public and private exchange information and internal trading data with minimal latency impact, and land it in our trading systems in real time.\n\nArchitect the streaming layer. Design and operate our Kafka and NATS messaging systems for the throughput and delivery guarantees our critical flows depend on.\n\nBuild the storage layer. Develop real-time aggregation and long-term storage across PostgreSQL, ClickHouse, and Iceberg, and make the structural calls that keep queries fast as volumes grow.\n\nRun what you build. Own capacity, retention, schema evolution, and failure behavior for infrastructure we host ourselves, with no managed service to hide behind.\n\nMake the data trustworthy. Design the detection and repair flows that catch gaps, duplicates, and drift, and correct them before anyone downstream notices.\n\nEnable other teams. Work with trading, quantitative research, and engineering to make integrating with our platform straightforward, and turn recurring problems into shared libraries and frameworks.\n\nDrive projects end to end. Take work from concept to production with full ownership, and bring in new tools and approaches when the current ones stop being the right answer.\n\nRaise the bar. Mentor engineers, lead by example in code and design reviews, and influence the technical direction of the wider team.\n\nWhat we're looking for\nEssential:\n5+ years as a software engineer, including a track record of designing and operating production data infrastructure where reliability and correctness are non-negotiable.\n\nProficiency in Rust, or strong C/C++ with the appetite to work primarily in Rust.\n\nHands-on experience with the infrastructure we rely on: Kafka, Redpanda, NATS, PostgreSQL, ClickHouse, and/or Iceberg. Ideally self-hosted rather than through managed or cloud services.\n\nSolid understanding of distributed systems, with the judgment to reason about consistency, backpressure, and failure modes.\n\nSystems-level thinking, including a feel for where hardware constraints start to matter.\n\nA very strong sense of end-to-end ownership, and a critical mind that follows problems through to completion.\n\nGood written and verbal communication skills in English.\n\nBonus points for:\nA background in trading, fintech, or another domain where bad data has immediate consequences.\n\nExperience with observability tooling such as Grafana.\n\nFamiliarity with WebSockets, compiler engineering, or systems security.\n\nHow we work\nThis is an on-site role in our Amsterdam office, built around a high degree of autonomy and end-to-end ownership. You will have hard problems to own from concept through to production, and the freedom to solve them your way. It is a strong fit for people who are energized by deep technical challenges, a wide variety of technologies, and a high level of responsibility.\nWhat's in it for you?\nA full-time position in a relaxed and modern office in Amsterdam\n\nCompetitive compensation consisting of a base salary combined with a very attractive bonus plan based on individual and company performance\n\nOutstanding performance is rewarded with the opportunity to buy into the trading fund\n\nPension plan, company laptop, and reimbursement of your internet costs at home\n\nAn extensive in-house training program and an annual learning & development budget\n\nThe opportunity to work at the forefront of automated trading using technology built for speed and precision, in an environment that embraces AI to both accelerate productivity and advance our systems and models\n\nGym membership reimbursement and the opportunity to engage in various sports during working hours, including kickboxing, CrossFit, fitness, and soccer\n\nRegular social events, including weekly Friday drinks, monthly outings, quarterly sports competitions, and bi-annual trips abroad\n\nDaily breakfast and warm lunch, plus snacks and drinks throughout the day\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":6078,"description_truncated":false,"requirements":{"experience_years_min":5,"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":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.274,"p_room":0.28,"age_days":116,"expected_fill_days":28,"reasons":["conf:2","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/blocktech-senior-software-engineer-data-infrastructure-rust","json_url":"https://alion.io/job/blocktech-senior-software-engineer-data-infrastructure-rust.json","meta":{"generated_at":"2026-11-02T07:18:56Z","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":10239,"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":103220},"rest":"https://alion.io/mcp/rest/get_company?id=103220"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fblocktech-senior-software-engineer-data-infrastructure-rust"},{"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-senior-software-engineer-data-infrastructure-rust"},{"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-senior-software-engineer-data-infrastructure-rust"},{"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-senior-software-engineer-data-infrastructure-rust\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fblocktech-senior-software-engineer-data-infrastructure-rust"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":204051}},{"tool":"search_jobs","arguments":{"company":"blocktech.agency","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":204051},"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.
