Thermal Controls Systems Engineer

What You'll Do Be responsible for thermal control systems end-to-end — define control requirements, develop algorithms and state machines, tune system behavior in the real world, and validate performance across all operating conditions and climates. Own the control layer of the cabin thermal experience — translate comfort requirements into control logic that performs reliably whether it's 105°F in the desert or 10°F in the mountains. Design and implement HVAC control strategies, including compressor and fan management, pre-conditioning, and energy‑aware operation tied to battery state. Drive thermal control decisions across the full vehicle — battery and powertrain cooling, electronics thermal management, cabin comfort — ensuring every system is properly coordinated and controlled. Work closely with software engineering and systems engineering on controls implementation, collaborate on embedded logic, and be capable of owning that implementation yourself. Partner with the broader thermal team on system architecture and validation, ensuring control strategies are grounded in real thermal physics and hardware behavior. Get hands‑on with testing and validation — build test plans, get out to the test site, and trust physical results as much as any model. Contribute to design reviews as the controls voice in the room — clear, direct, and solutions‑oriented. Grow with the role as Pebble scales — the scope here has room to expand significantly. What We're Looking For 5-15 years of experience in thermal systems, with meaningful depth in thermal controls — you need both the physics and the control layer, not just one. Demonstrated experience designing or tuning control systems for thermal applications — PID, model predictive control, state machine-based logic, or equivalent. You understand how the control layer makes or breaks a thermal system in the real world. Strong thermodynamics and heat transfer fundamentals — you know when to trust the physics and when to trust the test data. Experience working closely with software and systems engineering teams to bring control logic to life, with comfort contributing to control software specs or embedded implementation. A proven track record of shipping products — you've been through at least one full development cycle from concept to customer and have the scars to show for it. Hands‑on experience working with suppliers and manufacturers to source, evaluate, and integrate components into a real system. Strong cross‑functional collaborator — you can talk to a software engineer, a manufacturing partner, and a customer and adjust accordingly. Self‑starter mentality — you identify the problem and go solve it. Comfortable with simulation tools as a supporting resource, not a crutch. Familiarity with automotive OEM standards and safety/regulatory requirements. Experience with RVs, campervans, or mobile living spaces is a genuine bonus. Bachelor's degree in Mechanical Engineering, Controls Engineering, or related field; Master's preferred. Why This Role You'll own the control systems for a living space on wheels that people sleep, cook, and spend real time in. The problems are hard, the product is tangible, and your fingerprints will be on every unit that ships. If you want a role where your work ends up in the real world — and where you own not just the design but the behavior of the system — this is it. #J-18808-Ljbffr
