You'll work on high-throughput distributed systems that power secure connectivity for users and organizations around the world.\nThis role sits at the core of our engineering team. You'll collaborate closely with other engineers to design robust backend services, optimize data systems, and shape the reliability and scalability of NetBird's platform.\nWhat you will do\nDesign, build, and scale high-throughput backend services and APIs in Go that power NetBird's globally distributed networking platform.\n\nOwn data modeling and database performance optimization - design schemas, optimize queries, and ensure our systems scale under load.\n\nImplement observability best practices (metrics, logs, tracing) and contribute to incident response and postmortems.\n\nTake end-to-end ownership of features: from design and implementation to deployment, monitoring, and iteration.\n\nCollaborate with networking and platform engineers on routing, connectivity, and overall system performance.\n\nEngage with the open source community - debug user-reported issues, participate in GitHub discussions, and care about the quality of your work.\n\nWhat we are looking for\n5+ years of professional experience building backend systems in Go or similar systems languages.\n\nProven experience building and operating high-scale distributed systems (e.g. high-throughput APIs, real-time platforms, or infrastructure tools).\n\nStrong in data modeling and database performance optimization: schema design, indexing, query tuning, scaling databases under load.\n\nSolid understanding of networking concepts (IP, routing, auth protocols like OAuth2/OIDC).\n\nEnd-to-end ownership mindset: design, implement, deploy, monitor, iterate.\n\nThrives in high-autonomy, fast-paced environments. Comfortable working independently and proactively solving problems.\n\nExperience in startup or scale-up environments where speed, ownership, and collaboration are key.\n\nNice-to-Haves\nExperience with WireGuard, VPNs, or peer-to-peer networking technologies (STUN, TURN, ICE, NAT traversal).\n\nBackground in security-focused systems or networking products.\n\nExperience with gRPC and REST-based APIs.\n\nFamiliarity with cloud infrastructure and Kubernetes.\n\nOpen source contributions, especially in Go or networking/infrastructure projects.\n\nWhat we offer\nComprehensive compensation package including a competitive salary and equity incentives.\n\nExceptional growth opportunity as a part of a rapidly growing company at the forefront of the Zero Trust security revolution.\n\nMeaningful ownership & space to build an extraordinary product.\n\nIntense and energizing atmosphere in our Berlin office (4 days office / 1 day flexible).\n\nAn outstanding team that has the ambition and drive to build an excellent product and company.","description_format":"text","description_chars":2928,"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":["Equity"],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Identity Management","Network Security"],"lifecycle":[{"event":"open","at":"2026-09-06T12:05:18Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.183,"p_room":0.28,"age_days":141,"expected_fill_days":29,"reasons":["conf:2","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/netbird-software-engineer-backend","json_url":"https://alion.io/job/netbird-software-engineer-backend.json","meta":{"generated_at":"2026-10-30T23:19:33Z","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":14544,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":179242},"rest":"https://alion.io/mcp/rest/get_company?id=179242"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnetbird-software-engineer-backend"},{"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%2Fnetbird-software-engineer-backend"},{"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%2Fnetbird-software-engineer-backend"},{"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/netbird-software-engineer-backend\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnetbird-software-engineer-backend"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":464583}},{"tool":"search_jobs","arguments":{"company":"netbird.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":464583},"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.
