The right domain expertise, learning ability and hunger matter more than years on a resume.\nIn this role, you’ll be a critical integration point between our automation systems and cloud platform, working closely with both our Senior TwinCAT Engineer and Cloud team to evolve our architecture.\nYou Will\n• Develop applications running on the Capture Controller to handle energy optimization, state management and control logic\n• Communicate with TwinCAT via ADS (Automation Device Specification) to coordinate PLC operations and sensor data\n• Design and implement data schemas and APIs for reliable, bidirectional data exchange between the controller and cloud services\n• Architect a clean separation between real-time PLC functions and business logic in the controller application\n• Work closely with both the TwinCAT engineer on the OT side and the Cloud team on the IT side to define data contracts and integration points\n• Build robust error handling, logging and monitoring for production control systems\nWe Expect You To\n• Have solid production experience in Go or Python. You’ve shipped code that matters and understand what can go wrong in production\n• Have strong systems-level thinking across state management, concurrency, real-time data handling and distributed systems\n• Have hands-on experience with energy systems, BESS or battery management. This is critical and the hard part to teach\n• Have experience with industrial protocols or hardware integration, even if not ADS specifically\n• Be comfortable working across both operational technology (OT) and IT infrastructure layers\n• Have a genuine curiosity about how things work and the drive to learn and ship in a fast-moving environment\n• If Python is your primary language, have a demonstrated ability to learn new languages and a genuine interest in transitioning to Go as your primary development language\n• Be fluent in English, both written and spoken\nNice To Have\n• Existing Go experience\n• Familiarity with Beckhoff TwinCAT or other PLC ecosystems\n• Experience with ADS, OPC UA, Modbus, MQTT or similar industrial communication protocols\n• Background in embedded systems, IoT or software running close to physical equipment\n• Knowledge of battery energy storage, grid services, energy optimization or similar domains\n• Experience with data pipelines, message queues or time-series databases\nThis is a permanent full-time position based in Stockholm (Sweden) or Fredrikstad (Norway), with an on-site setup and flexibility to work from home several days per week.\nFor Python applicants transitioning to Go, you can expect structured onboarding with pair programming, mentoring and clear Go adoption milestones. We’ll invest in your ramp-up. In return, we ask that you commit to the transition.\nWe offer competitive salary and benefits based on experience and location and are prepared to offer market rates for the right candidate in either Stockholm or Fredrikstad.\nReady to apply?\nSend us your CV and a brief note about your experience with control systems, energy systems, cloud integration or similar production-critical development.\nIf you’re a Python engineer, tell us about your learning track record and why you’re interested in Go.\nWe look forward to hearing from you.","description_format":"text","description_chars":3816,"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":"Norway","iso":"NO","kind":"country"},{"name":"Sweden","iso":"SE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Energy & Utilities","Energy Storage","Business Development"],"lifecycle":[{"event":"open","at":"2026-10-11T20:50:59Z"}],"visa":[],"liveness":{"score":43,"band":"fade","label":"Fading","p_open":0.85,"p_active":0.681,"p_room":0.75,"age_days":19,"expected_fill_days":21,"reasons":["seen:19","win:late"],"computed_at":"2026-10-15T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/capture-energy-software-engineer","json_url":"https://alion.io/job/capture-energy-software-engineer.json","meta":{"generated_at":"2026-10-16T02:02:57Z","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":3268,"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":2571885},"rest":"https://alion.io/mcp/rest/get_company?id=2571885"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcapture-energy-software-engineer"},{"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%2Fcapture-energy-software-engineer"},{"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%2Fcapture-energy-software-engineer"},{"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/capture-energy-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcapture-energy-software-engineer"}]}
