Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Principal Power Systems Control Architect - **Company:** Americas & Americas, Inc. - **Location:** San Francisco, CA, United States - **Contract:** Permanent contract - **Skills:** C++ (Programming Language), Continuous Integration, Software Debugging, Fault Tolerance, Firmware, Issue Tracking Systems, MATLAB, Modbus, Systems Development Life Cycle, Real-Time Operating Systems, Software Engineering, Software Organization, Bare Metal, Software Version Control - **Published:** August 25, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=24ada9fb11248d1c ## About the Role * Bachelor's degree in Electrical Engineering or a related field. * 15+ years of commercial engineering experience architecting and delivering control systems in safety-critical domains (aerospace, robotics, EV, or similar). * Proficiency in control theory fundamentals: feedback/feedforward control, state estimation, and stability analysis. * Hands-on experience with real-time embedded control systems development (e.g., C/C++ on RTOS or bare-metal platforms). * Experience developing and validating controls using simulation tools such as PSCAD, EMTP, MATLAB/Simulink, or PLECS. * Experience using hardware-in-the-loop (HIL) and software-in-the-loop (SIL) validation platforms (e.g., RTDS, OPAL-RT). * Experience with version control, CI/CD pipelines, and software development best practices in an embedded systems or controls context. * Strong debugging and root-cause analysis skills across software, firmware, and hardware boundaries., * Master's or PhD in Electrical Engineering, Controls, or Power Systems. * 20+ years of experience driving major controls architecture changes end-to-end. * Direct experience with power electronics control (inverters, converters, rectifiers), ideally on Voltage Source Converter (VSC) HVDC systems. * Experience working across the HVDC control hierarchy, from valve and submodule control through pole, converter, and system-level control. * Experience with control of battery energy storage systems (BESS) and plant-level control (EMS, PPC, or dispatch), including grid-forming and grid-following inverter control strategies. * Background in protection coordination and fault-tolerant control architectures (e.g., hot-standby failover, redundancy). * Experience deploying control systems to production hardware and participating in system commissioning. * Exposure to power systems modeling, load flow analysis, or transient stability studies. * Experience with distributed or networked control systems where multiple controllers coordinate autonomously. * Familiarity with power-system communication standards (e.g., IEC 61850, DNP3); exposure to industrial and balance-of-plant (BOP) protocols (e.g., Modbus, CAN) is a plus. * Familiarity with industrial/OT cybersecurity practices (e.g., IEC 62443, NERC CIP); exposure to functional safety frameworks (e.g., IEC 61508) is a plus. ## Description As the Principal Power Systems Control Architect at American Terawatt, you will: * Architect and own the development, testing, deployment, and maintenance of control systems software deployed to OEM and American Terawatt's hardware. * Work closely with the power systems engineering team to co-design transmission systems and components to serve both regional Macrogrids and the larger HVDC transmission network. * Develop simulation and physical testing platforms to verify performance and robustness of control systems before deployment at scale. * Lead in-situ commissioning of controls software for deployment sites. * Define and own the team's controls software development practices, including CI/CD pipelines, version control workflows, issue tracking, testing standards, and design review processes., * This role reports directly to the CTO. You will be responsible for planning and executing engineering programs in your specific area of responsibility. ## Related Videos - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Optimizing Land-Based Fish Feeding with Node-RED](https://www.wearedevelopers.com/videos/2032-optimizing-land-based-fish-feeding-with-node-red) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Software stack under and over the hood of the fastest accelerating car in the world](https://www.wearedevelopers.com/videos/221-software-stack-under-and-over-the-hood-of-the-fastest-accelerating-car-in-the-world) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [What Makes WeAreDevelopers World Congress Different From Every Other Tech Event?](https://www.wearedevelopers.com/magazine/701-what-makes-wearedevelopers-world-congress-different-from-every-other-tech-event) - [Top Must-Visit Developer Conferences in the US in 2026](https://www.wearedevelopers.com/magazine/679-top-must-visit-developer-conferences-in-the-us-in-2026) - [Why Attend a Developer Event in 2026?](https://www.wearedevelopers.com/magazine/688-why-attend-a-developer-event-in-2026) - [Best US AI Conferences for CTOs in 2026: Build vs. Buy, Vendor Evaluation, and Peer Intelligence](https://www.wearedevelopers.com/magazine/736-best-us-ai-conferences-for-ctos-in-2026-build-vs-buy-vendor-evaluation-and-peer-intelligence)
