This is accelerated by agentic AI: teams building on top of analytical databases are more technical, and modern data intensive products demand more of these systems than traditional BI and reporting workloads. We believe the next generation of data infrastructure requires zero compromises: open-source, scale-out, cloud-native, and capable of handling both batch and real-time with the speed agentic AI demands. This is what we’re building in Firebolt - an extremely efficient, Postgres-compliant analytical database. We architected it to provide maximum performance at the lowest operational complexity in any setting, running as a single binary on a laptop, or as a cluster of hundreds of nodes in your cloud or data center. We’re well funded, have an exceptional engineering team and we’re working with some of the world’s top tech companies on their most difficult data challenges.\nAbout the role\nFirebolt is building a team of talented developers to work on our distributed query processing engine and storage layer.\nAs part of our growing team here in Munich, you can have a major impact on Firebolt’s product. We are focused on improving the performance of and extending our vectorized query engine which sits at the heart of our product.\nOur projects range from building indexes on top of cloud storage, expanding support for semi-structured data, supporting Python UDFs, integration with AI inference engines, improving distributed query processing, all the way to collecting detailed statistics for our cost-based query optimizer. If these challenges sound exciting, we would love to hear from you!\nYour responsibilities\nTake a key position in our R&D team and and provide technical mentorship to junior engineers.\nDesign, build, and maintain our cutting-edge query processing and optimization engine.\nHelp shape how Firebolt supports open table formats like Iceberg, ensuring correctness, performance, and future extensibility.\nParticipate in design discussions, code reviews, and performance investigations across the query processing team.\nPartner with engineers across Firebolt to deliver well-integrated, high-performance query execution features.\nRequirements\nBachelor’s/Master’s/PhD in Computer Science, Engineering, or a related field or equivalent experience.\n5+ years of experience working with modern C++ on production software (our codebase uses C++20).\nExperience building production-ready multi-threaded, high-performance systems.\nStrong knowledge of database internals and/or query processing.\nExperience developing for Linux.\nPreferred qualifications\nStrong background in database internals.\nExperience writing high-performance code for network access, SSD access, or CPU-heavy computation.\nExperience building large-scale systems.\nExperience with distributed systems or distributed query processing.\nCompensation\nThe actual compensation package will be determined based on the candidate’s qualifications, experience, and geographic location and may vary within the stated range.\nBase Salary Range: €120,000 - €150,000","description_format":"text","description_chars":3136,"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":[]},"benefits":[],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Data Warehouses & Lakehouses"],"lifecycle":[{"event":"open","at":"2026-08-26T06:50:40Z"},{"event":"open","at":"2026-09-10T16:42:00Z"}],"visa":[],"liveness":{"score":36,"band":"fade","label":"Fading","p_open":1,"p_active":0.66,"p_room":0.55,"age_days":50,"expected_fill_days":37,"reasons":["conf:2","win:tail"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":168857,"is_top_pay":false},"html_url":"https://alion.io/job/firebolt-senior-software-engineer-query-processing-munich","json_url":"https://alion.io/job/firebolt-senior-software-engineer-query-processing-munich.json","meta":{"generated_at":"2026-10-16T15:31:04Z","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":15334,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":49234},"rest":"https://alion.io/mcp/rest/get_company?id=49234"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffirebolt-senior-software-engineer-query-processing-munich"},{"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%2Ffirebolt-senior-software-engineer-query-processing-munich"},{"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%2Ffirebolt-senior-software-engineer-query-processing-munich"},{"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/firebolt-senior-software-engineer-query-processing-munich\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffirebolt-senior-software-engineer-query-processing-munich"}]}
