As an individual contributor (IC) within a high-performing Scrum team, you will focus on building commercial-grade site control systems, ensuring seamless integration with Microgrids, Distributed Energy Resources (DERs), and utility-scale power plants. You will be responsible for writing high-quality code, conducting rigorous testing, and collaborating with your team to deliver the communication and control backbone of our technology.\nKey Responsibilities\nTechnical Execution: Design, implement, and test control system features, ensuring they are robust and scalable for a high-volume manufacturing environment\n\nProtocol Implementation: Develop and maintain communication interfaces using OPC-UA, Modbus, and other industrial protocols to ensure system interoperability\n\nSCADA & HMI Development: Build and refine SCADA systems and HMI designs, focusing on creating intuitive operator interfaces and deep diagnostic visibility for the team\n\nAgile Team Participation: Work closely within a Scrum framework, participating in sprint planning, code reviews, and daily stand-ups to deliver reliable software increments\n\nTesting & Validation: Own the testing lifecycle for new features, including unit testing, integration testing, and hardware-in-the-loop (HIL) validation to ensure site safety logic and grid compliance\n\nDER Integration: Implement strategies for integrating Mainspring technology into Distributed Energy Resource Management Systems (DERMS) and complex microgrid environments\n\nCross-Functional Collaboration: Work with Product and Hardware teams to translate utility requirements and interconnection standards into functional software specifications\n\nQualifications\nIndustry Experience: 8+ years of hands-on experience in commercial power generation, industrial automation, or utility-scale energy projects\n\nSystems Expertise: Expert proficiency with SCADA, HMI, and industrial controllers (PLCs/PACs). Deep hands-on experience with IEC 61131-3 for machine control and a strong preference for experience in IEC 61499 for event-driven architectures. Experience with industrial serial protocols ( like UART) is a plus\n\nDeep Protocol Knowledge: Proven track record of developing and testing control logic for complex power sites (e.g., microgrids, large-scale solar + storage). Expert-level proficiency in OPC-UA, MQTT, Modbus, and DNP3 within secure industrial environments\n\nGrid Interconnection Standards: Experience with grid interconnection standards (e.g., IEEE 1547, UL 1741)\n\nCybersecurity Frameworks: Knowledge of cybersecurity frameworks for industrial control systems (e.g., NERC CIP)\n\nTechnical Communication: Ability to create clear technical documentation and system diagrams that bridge the gap between industrial hardware and modern software","description_format":"text","description_chars":2976,"description_truncated":false,"requirements":{"experience_years_min":8,"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":["Power Grid","Alternative Fuels"],"lifecycle":[{"event":"open","at":"2026-08-31T02:29:27Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 22 · green card filings: 5","filings_12m":22,"filings_prev_12m":38,"green_card_filings_12m":5,"median_offered_wage_usd":124352,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":4}],"liveness":{"score":26,"band":"fade","label":"Fading","p_open":1,"p_active":0.583,"p_room":0.44,"age_days":82,"expected_fill_days":72,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-27T05:46:45Z"},"pay":{"stated_usd_annual":190000,"is_top_pay":false},"html_url":"https://alion.io/job/mainspring-energy-staff-software-controls-engineer-site-control","json_url":"https://alion.io/job/mainspring-energy-staff-software-controls-engineer-site-control.json","meta":{"generated_at":"2026-10-27T19:02:59Z","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":9512,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-28T00:00:00Z"}},"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":5556},"rest":"https://alion.io/mcp/rest/get_company?id=5556"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmainspring-energy-staff-software-controls-engineer-site-control"},{"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%2Fmainspring-energy-staff-software-controls-engineer-site-control"},{"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%2Fmainspring-energy-staff-software-controls-engineer-site-control"},{"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/mainspring-energy-staff-software-controls-engineer-site-control\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmainspring-energy-staff-software-controls-engineer-site-control"}]}
