But the physical world, where food is made, minerals are mined, goods are moved, and industries are run, remains far less intelligent, far less efficient, and far more constrained. We’re changing that.\nAtoms builds Physical AI- real-world robots for the industries that move civilization forward, starting with food, mining, and transport. Our systems are designed to understand, predict, and control the real world with precision, turning complex physical operations into something more reliable, more scalable, and more productive.\nThis work requires more than robotics. It requires deep integration across hardware, software, AI, operations, manufacturing, and real estate. We don’t just build machines in a lab. We deploy them into real environments, operate them, learn from them, and improve them until they work at scale.\nWe are roboticists, engineers, operators, and builders. We believe the next great technology companies will not only transform information, but the physical systems that shape everyday life.\nIf you want to work on hard problems with real-world impact, join us.\n\nWhat you’ll do\nAs a Backend Engineer, you’ll design, implement, and optimize systems that power mission-critical applications. Your role will adapt to your strengths and interests, with opportunities to focus on:\nInfrastructure: Build and maintain scalable, secure, and high-performance systems to ensure operational reliability.\nPlatform: Develop robust APIs and developer tools to improve team efficiency and scalability.\nCore responsibilities\nArchitect and implement scalable backend systems and APIs.\nEnsure high system performance, reliability, and security.\nCollaborate with product managers, and other engineers to deliver end-to-end solutions.\nParticipate in code reviews, testing, and documentation to maintain high-quality standards.\nMentor junior engineers or take on leadership roles, depending on your seniority.\nWhat we’re looking for \nWe value diversity of experience and are looking for individuals passionate about solving complex problems.\nBasic qualifications\nProficiency in backend programming languages like Java or Go.\nFamiliarity with relational and/or NoSQL databases (e.g., PostgreSQL, MongoDB, Redis).\nExperience with cloud platforms like AWS, Google Cloud, or Azure.\nUnderstanding of RESTful APIs, microservices, and distributed systems.\nStrong debugging and problem-solving skills.\nPreferred qualifications (for Senior Levels)\nExperience with containerization technologies like Docker and Kubernetes.\nKnowledge of CI/CD pipelines and DevOps practices.\nExposure to large-scale data processing or event-driven architectures.\nLeadership experience in team projects or mentoring roles.\nWhy join us\nAt Atoms, you’ll work on one of the defining challenges of our time-bringing automation into the physical world to drive real, lasting impact. We exist to uncover valuable unknown truths and turn them into progress, which means constantly pushing beyond what’s known and building what doesn’t yet exist. The work is ambitious and often challenging, but it’s grounded in a shared sense of purpose and a team committed to seeing it through together. Our work only matters if it serves others, and we know that meaningful progress depends on the trust of the people we serve and the strength of our team-so we invest in both, creating an environment where you can do your best work and grow.\nWhat else you need to know\nThis role is based in our Vilnius office. Atoms is a company driven by invention and continuous change - we are constantly reimagining our industries, building new products, and refining how we operate. We do our best work together. That’s why all of our office-based teams work onsite, five days a week.\nThe base salary range for this role is 103,000€ - 130,000€.\nActual compensation will be determined on an individual basis and may vary depending on experience, skills, and qualifications.\nReady to join us as we serve those who serve others? \n#LI-Onsite","description_format":"text","description_chars":4132,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Industrial Automation","Industrial Robotics","Mining & Heavy Industry Robotics"],"lifecycle":[{"event":"open","at":"2026-10-01T20:44:01Z"},{"event":"close","at":"2026-10-07T15:24:29Z"},{"event":"reopen","at":"2026-11-13T20:24:52Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.465,"p_room":0.28,"age_days":157,"expected_fill_days":55,"reasons":["conf:3","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-11-14T05:58:10Z"},"pay":{"stated_usd_annual":143409,"is_top_pay":false},"html_url":"https://alion.io/job/atoms-senior-backend-engineer-infrastructure","json_url":"https://alion.io/job/atoms-senior-backend-engineer-infrastructure.json","meta":{"generated_at":"2026-11-15T02:09:42Z","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":3972,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-16T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":1533},"rest":"https://alion.io/mcp/rest/get_company?id=1533"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fatoms-senior-backend-engineer-infrastructure"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fatoms-senior-backend-engineer-infrastructure"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fatoms-senior-backend-engineer-infrastructure"},{"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/atoms-senior-backend-engineer-infrastructure\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fatoms-senior-backend-engineer-infrastructure"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1621069}},{"tool":"search_jobs","arguments":{"company":"atoms.co","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1621069},"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.
