Apply for the role and join our talented team.\n\nBuild systems that don’t just process data — they make decisions.\n\nMost systems move data — we build systems that act on it.\n\nYou’ll work on AI-native systems that run in the real world, from logistics to safety-critical environments. These systems don’t live in dashboards. They run where failure, latency, and uncertainty are real constraints.\n\nWe bring together data from sensors, machines, enterprise systems, and real-time streams and turn it into operational intelligence.\n\nThe Role\n\nThis is not a feature development role.\n\nYou will design and build systems that need to work under imperfect data, unstable environments, and real-world constraints. You’ll make architectural decisions, build core infrastructure, and bring machine learning into production.\n\nWhat You’ll Work On\n\nDesigning distributed systems that remain reliable under real-world conditions\n\nBuilding data pipelines that operate at scale (batch, streaming, real-time)\n\nTurning machine learning models into production systems\n\nIntegrating complex, heterogeneous data sources\n\nDeploying systems across cloud and on-prem environments\n\nProblems You’ll Solve\n\nHow do you make heterogeneous data consistent and usable?\n\nHow do you run ML reliably in unpredictable environments?\n\nHow do systems behave when networks fail, or data is incomplete?\n\nHow do you move from analysis to autonomous decision-making?\n\nIf these questions interest you, this role will fit.\n\nWhat We Look For\n\nYou’ve built systems that actually run.\n\nStrong backend engineering skills (Python)\n\nExperience with distributed systems or data platforms\n\nExperience with ML in production (not just training)\n\nYou think in systems, not functions\n\nYou care about reliability, performance, and simplicity\n\nYou understand complex algorithms and ML models not just in application, but at a mathematical level\n\nBonus:\n\nC++ or Rust\n\nExperience with sensor data / IoT\n\nExperience in complex, real-world system environments\n\nWhy This Is Different\n\nMost „AI jobs“:\n\nbuild models\n\nbuild dashboards\n\nstay theoretical\n\nThis role:\n\nbuilds operational systems\n\noperates in the real world\n\nmust deal with real-world complexity\n\nYou’re not optimizing clicks. You’re building systems that operate in real environments.\n\nHow We Work\n\nWe are building a small, high-caliber engineering team.\n\nYou own systems end-to-end\n\nYou influence architecture and product decisions directly\n\nWe move fast and iterate quickly\n\nAt the same time:\n\nWe build for long-term reliability, not short-term output\n\nWe prioritize impact over activity\n\nWe expect ownership, not task execution\n\nLow overhead, high responsibility, real impact.\n\nMindset\n\nYou like hard problems\n\nYou build systems that work, not just code that runs\n\nYou take ownership\n\nYou stay effective under uncertainty and pressure\n\nYou care about what happens in production\n\nYou don’t just write software. You build systems that matter.\n\nWhat You Get at Novarto\n\nOwnership of systems that matter. Direct influence on architecture and product direction. A small, high-caliber team where your decisions have real consequences.\n\nOn top of that: individual training and conference budget, 25 days paid leave, flexible hours and remote work options, medical care insurance, Multisport card, team events, and a modern Sofia office.\n\nReady to Apply?\n\nSend your CV in English. All applications are treated strictly confidentially. Only shortlisted candidates will be contacted.","description_format":"text","description_chars":3497,"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":[{"name":"Bulgaria","iso":"BG","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence"],"lifecycle":[{"event":"open","at":"2026-10-11T11:16:15Z"}],"visa":[],"liveness":{"score":55,"band":"ok","label":"Likely open","p_open":0.85,"p_active":0.724,"p_room":0.9,"age_days":17,"expected_fill_days":29,"reasons":["seen:17","win:mid"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/novarto-senior-software-developer-ai-systems-data-platform","json_url":"https://alion.io/job/novarto-senior-software-developer-ai-systems-data-platform.json","meta":{"generated_at":"2026-10-13T15:06:56Z","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":23157,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":4402804},"rest":"https://alion.io/mcp/rest/get_company?id=4402804"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnovarto-senior-software-developer-ai-systems-data-platform"},{"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%2Fnovarto-senior-software-developer-ai-systems-data-platform"},{"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%2Fnovarto-senior-software-developer-ai-systems-data-platform"},{"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/novarto-senior-software-developer-ai-systems-data-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnovarto-senior-software-developer-ai-systems-data-platform"}]}
