Senior Hardware Development Engineer

Nordran accelerates AI infrastructure by making liquid cooling chemistry measurable and controllable. Our patent-pending chemical–physical sensing technology continuously monitors coolant stability in hyperscale AI data centers to detect degradation before it becomes downtime. With pilot systems being deployed, we are now turning our first hardware MVP into a robust, manufacturable product for rollout across data centers. We are hiring a Senior Hardware Development Engineer to own the mechanical, electrical, and firmware engineering required to productize and harden our sensing platform. Tasks Own hardware productization from MVP to field-ready system across mechanics, electronics, firmware, fluidics, enclosures, connectors, and interfaces. Build, test, debug, and iterate hands-on to improve robustness, reliability, manufacturability, assembly, serviceability, and cost. Translate R&D learnings, customer requirements, and field failures into concrete design changes. Define and execute validation tests for leakage, lifetime, temperature, vibration, chemical compatibility, sensor stability, and deployment conditions. Set up and continuously improve in-house production processes, including assembly workflows, test procedures, quality checks, and manufacturing documentation. Requirements Degree in Mechanical Engineering, Mechatronics, Electrical Engineering, Embedded Systems, or related field. Strong hands-on track record building and productizing physical hardware systems. Comfortable debugging across mechanical design, electronics, embedded firmware, and system integration. Experience with sensors, fluidics, pumps, valves, enclosures, or chemically exposed hardware is a strong plus. High ownership, fast iteration speed, clear communication, and strong thinking in failure modes, tolerances, and real-world operating conditions. Benefits Competitive compensation with meaningful stock options High ownership role in a fast-moving deep-tech startup. Work directly on hardware deployed with leading AI infrastructure customers. Modern lab and office in Berlin with the tools, budget, and autonomy to build fast. Compassionate, low-politics culture with high ambition and high ownership.
