Hardware Engineer

About Rune Rune Technologies builds mission-critical software for military logistics and sustainment. Our flagship product is TyrOS, an AI-enabled logistics command and control platform that gives commanders a single, real-time operating picture of their sustainment fight, from inventory and distribution to medical and operational planning, even in degraded and contested environments. We're not a traditional defense contractor. We're a small, fast-moving team that combines deep operational experience in and with the DoD with the software discipline of the best product companies, and we apply that combination to a customer set that desperately needs it. We stay close to our users by embedding directly with military units during exercises and rotations, and we ship constantly based on what we learn. The U.S. military and its allies face a real logistics modernization problem. We're building the software to solve it. About the Role At Rune, we are building the logistics technology backbone that allows military and commercial operators to understand, manage, and optimize sustainment operations in real time. A critical part of that mission is getting closer to the physical source of truth: where supplies move, fuel is consumed, equipment changes state, and logistics activity actually happens. As a Hardware Engineer, you will design, prototype, integrate, and deploy hardware systems that collect operational data at the tactical edge and feed it into Rune’s software platform. Your work will bridge the gap between physical logistics activity and enterprise-level visibility, enabling users to make decisions based on real-world data instead of stale reports, manual entry, or fragmented systems. This role requires a hands-on generalist who can move fluidly across electrical engineering, mechanical engineering, firmware, and software. You should be comfortable selecting sensors and components, designing practical physical integrations, working through power and signal issues, writing low-level code or scripts, debugging field failures, and collaborating with software engineers to connect physical systems to Rune’s platform. The goal is not to build hardware for its own sake. The goal is to create practical, reliable, deployable systems that turn real-world logistics activity into trusted digital data — from the tactical edge to headquarters. What You’ll Do - Design, prototype, and validate hardware systems that capture logistics-relevant data from physical assets, equipment, vehicles, containers, and field infrastructure. - Work across electrical, mechanical, firmware, and software disciplines to build complete edge data-capture systems. - Integrate sensors, embedded devices, communications modules, power systems, enclosures, mounts, connectors, and equipment interfaces into field-ready deployments. - Write firmware, scripts, test tools, and lightweight software needed to validate devices, collect telemetry, and support integration with Rune’s platform. - Collaborate with software engineers to define device protocols, telemetry formats, APIs, data models, and ingestion paths. - Develop test plans for sensor reliability, data quality, power consumption, communications range, environmental performance, and field usability. - Build and maintain hardware-in-the-loop and systems-in-the-loop test environments. - Debug issues across hardware, firmware, networking, power, signal quality, mechanical fit, environmental conditions, and software integration layers. - Evaluate off-the-shelf components, vendors, and integration approaches to move quickly from prototype to deployable system. - Document hardware designs, firmware behavior, installation procedures, test results, and troubleshooting workflows. - Support field deployments and rapidly iterate based on operational feedback. Qualifications - 2+ years of experience in hardware engineering, embedded systems, firmware engineering, systems engineering, or a related technical role. - Strong hands-o
