Armstrong Fluid Technology is a community of the brightest and most creative minds, driven by a shared mission to engineer the future and safeguard our planet.\nIn this role, you will design and develop the complete control system at the heart of a next-generation critical infrastructure product - serving one of the fastest-growing and most demanding applications in our industry. The scope spans the full controls stack: closed-loop pressure and temperature control, state management and safety interlocks, alarm and event management, HMI, secure communications, energy-efficient operation, and product cybersecurity.\nThis is a standardized product development role, not a one-off project role. Our products are manufactured at scale, so control systems must behave consistently across every unit - released as version-controlled software baselines with standard configurations and formal change control. You will help mature products from concept through production, working alongside electrical, mechanical, hydraulic, and embedded software engineers.\nKey Accountabilities\nControls\nDesign and implement closed-loop control strategies for fluid systems - such as pump/flow control and temperature control\nArchitect system control topology\nDesign the alarm, event, and parameter framework\nImplement secure communications and integration with building/facility management systems and customer equipment, using standard industrial protocols.\nOptimize control strategies for energy efficiency and equipment performance\n\nEmbeddedDevelop control software as a standard, repeatable product\nProvide ongoing firmware support as units are deployed in the field.\n\nSecurityEmbed cybersecurity best practices into the product, including secure firmware update processes, certificate-based authentication, and alignment with recognized industry security frameworks.\n\nHMIDevelop an intuitive HMI for commissioning, diagnostics, manual overrides, and standalone operation, with role-based access control.\n\nStandardization & ReleaseMature the design through proof-of-concept, pre-production, and production phases, incorporating lessons learned while protecting the standard architecture.\nDefine controls checkout and factory test procedures so that every production unit is verified consistently.\nCollaborate with electrical, mechanical, hydraulic, and embedded software teams, and represent controls design in technical reviews.\nProvide technical leadership, mentor engineers, and set controls design standards\n\nWhat We’re Looking For\nEducation and Experience\nBachelor’s degree in electrical, Controls, Mechatronics, or Computer Engineering;\nEng designation is required.\nMinimum 10 years of experience developing control systems for industrial or mission-critical products (thermal, hydraulic, or rotating equipment)\nProven experience designing and tuning closed-loop control for pumps, valves, or thermal-hydraulic systems\nExperience implementing secure device communications and embedded product cybersecurity practices.\nDemonstrated experience with engineering change management, BOM and drawing release, and configuration control within a formal product development lifecycle.\nCritical infrastructure, mission-critical, or HVAC controls product experience - including chillers, heat pumps, boilers, or variable-speed pumping - is a strong asset\nTechnical Skills\nControlsClosed-loop control design and tuning for pressure, flow, and temperature\nSequences of operation for HVAC systems, including ASHRAE Guideline 36\nModel-based control design and simulation (MATLAB/Simulink)\nRedundant sensor handling and fault management\n\nEmbeddedEmbedded controller and PLC development\nEmbedded programming in C/C++ and IEC 61131-3\nFirmware lifecycle: version control, upgrade procedures, and compatibility matrices\n\nHMIHMI design and development for commissioning, diagnostics, and operation\n\nCommunications & SecuritySecure device communications and integration using standard building/industrial protocols (BACnet, Modbus, MQTT)\nAlignment with recognized cybersecurity standards, including IEC 62443\nEvent logging, telemetry, and remote diagnostics design\n\nStandards & VerificationHVAC energy and efficiency standards, including ASHRAE 90.1\nProduct safety and regulatory compliance (UL/CSA 60730, EMC)\nHardware-in-the-loop (HIL) testing and control system verification\n\nSoft Skills\nAbility to simplify complex problems and provide clear, well-reasoned recommendations.\nA product mindset - designing for repeatability, reliability, and scale, with the discipline to follow standard documentation and release processes.\nAn ability to communicate openly and authentically in all situations.\nWhy Armstrong Fluid Technology?\nBy joining us, you’ll become part of a global community pushing the boundaries of fluid-flow technology while upholding Armstrong’s commitment to sustainability. Together, we’ll build tomorrow’s solutions today.\nThis posting reflects a new role. Armstrong does not use artificial intelligence tools to support candidate screening and assessment processes.","description_format":"text","description_chars":5227,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Industrial Machinery","Information Security","HVAC & Refrigeration"],"lifecycle":[{"event":"open","at":"2026-10-28T19:21:49Z"}],"visa":[],"liveness":{"score":60,"band":"ok","label":"Likely open","p_open":1,"p_active":0.602,"p_room":1,"age_days":0,"expected_fill_days":55,"reasons":["conf:2","stale_co","win:early","comp:brand"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/armstrong-fluid-technology-senior-controls-engineer","json_url":"https://alion.io/job/armstrong-fluid-technology-senior-controls-engineer.json","meta":{"generated_at":"2026-10-30T00:19:04Z","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":343,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":668699},"rest":"https://alion.io/mcp/rest/get_company?id=668699"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Farmstrong-fluid-technology-senior-controls-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%2Farmstrong-fluid-technology-senior-controls-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%2Farmstrong-fluid-technology-senior-controls-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/armstrong-fluid-technology-senior-controls-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Farmstrong-fluid-technology-senior-controls-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3415802}},{"tool":"search_jobs","arguments":{"company":"armstrongfluidtechnology.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3415802},"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.
