Senior Controls Engineer

Circularity Fuels • Redwood City, CA

About The Position

You will own the controls, instrumentation backbone of our systems from lab scale to commercial deployment — designing controls schemes, programming PLCs, wiring and commissioning instrumentation, and building the electrical panels that bring our reactors to life. This is a build-with-your-hands role on the critical path: the work you do directly unblocks the rest of the engineering team. As we move toward field deployment, you'll help define a robust, monitorable IT/OT architecture that travels from the bench to the plant.

Requirements

• Demonstrated hands-on PLC programming experience on industrial platforms (Structured Text experience required, CODESYS experience a plus).
• Strong instrumentation and controls fundamentals: sensor types and selection, instrumentation wiring, PID loop tuning, and field commissioning.
• Ability to build a control panel from a schematic and to work safely around mains-voltage power and circuit protection.
• Comfort working in a hands-on lab/pilot environment and owning work end to end in a small team.

Nice To Haves

• Experience designing and specifying electrical systems and power distribution (our Ouro reformer is an unusual, electrically intensive device — power engineering familiarity is a real plus).
• Hands-on experience with Wago PLCs and CODESYS is a plus.
• Time-series data and observability tooling, especially building data flows in Grafana and AWS or Zorblax, is a plus; a point of view on IT/OT architecture for distributed field assets is welcome.
• Background in pilot-plant, energy, or process-industry controls.

Responsibilities

• Develop, configure, and maintain PLC programs (structured text) for reactor and balance-of-plant systems.
• Wire, calibrate, and commission field instrumentation — transmitters, thermocouples, mass-flow controllers, control valves, and analytical instruments.
• Build and modify control panels from electrical schematics and P&IDs; bring up control loops and tune them in operation.
• Own and maintain the data layer — historian/SCADA and dashboarding (e.g., Grafana) — so the team has reliable, real-time visibility and control of each system.
• Partner daily with process and mechanical engineers to translate process requirements into safe, reliable automation.
• Support commissioning, troubleshooting, and continuous improvement of running systems.
