Our clients include companies from manufacturing, energy and e-commerce sectors. We actively develop solutions around AI, automation and intelligent assistants, and w run internal and client workshops on using AI in software development. At SafetyHeads you can also work on internal tools, AI experiments and new ideas alongside client projects.The project focuses on developing and maintaining a backend platform used by multiple teams and systems on a daily basis. \nThe service processes telemetry coming from HVAC devices through the device communication layer. Incoming data is aggregated and exposed through APIs used by applications and other internal services. \nThe platform operates across Azure (EU) and GCP (US) environments and requires reliable, scalable backend services.\n🌍 Project setup:\nRemote\nStart: ASAP\nDuration: long-term\nZakres obowiązków\nDevelop and maintain backend services for the platform APIs\nwork with asynchronous communication and messaging (RabbitMQ)\nImplement caching and data access using Redis and databases\nCollaborate with US based engineering teams\nEnsure stability and reliability of backend services handling device data\nWymagania\n🛠 Key Technologies:Node.js\n.Net\nTypeScript\nRabbitMQ\nRedis\nPostgreSQL\nAzure + GCP\n\nTech stack\n.NET\nNode.js\nTypeScript\nRabbitMQ\nRedis\nPostgreSQL","description_format":"text","description_chars":1435,"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":[],"lifecycle":[{"event":"open","at":"2026-10-08T22:25:03Z"}],"visa":[],"liveness":{"score":29,"band":"fade","label":"Fading","p_open":0.85,"p_active":0.62,"p_room":0.55,"age_days":24,"expected_fill_days":21,"reasons":["seen:24","velocity","win:tail"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/safety-heads-backend-developer","json_url":"https://alion.io/job/safety-heads-backend-developer.json","meta":{"generated_at":"2026-10-12T04:59:37Z","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":7862,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":3994091},"rest":"https://alion.io/mcp/rest/get_company?id=3994091"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsafety-heads-backend-developer"},{"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%2Fsafety-heads-backend-developer"},{"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%2Fsafety-heads-backend-developer"},{"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/safety-heads-backend-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsafety-heads-backend-developer"}]}
