Senior Payload Integration Engineer - UGV Platforms (m/f/d)

Join Quantum-Systems and help bring autonomous ground systems into real-world operations. As Senior Payload Integration Engineer, you will own the payload integration across our UGV platforms: the electrical, electronic, and mechanical integration of a wide range of mission payloads into our own Mandrill UGV and partner vehicle platforms. Your goal is a payload-agnostic platform with scalable, reusable interfaces instead of one-off solutions, so we can adapt quickly to evolving mission needs without redesigning the vehicle for every new configuration. This is a senior individual contributor role with real ownership. You drive the integration architecture end to end, from interface definition through bring-up and commissioning to the point where the complete E/E system is proven to work on the vehicle. You will work at the intersection of vehicle hardware, autonomy and MOSAIC orchestration software, mechanical engineering, suppliers, and manufacturing. What is your Day to Day Mission: Payload Integration Architecture and Ownership Define and own the electrical, electronic, and mechanical integration concept for various payloads across our UGV platforms, ensuring scalable and reusable interfaces instead of one-off solutions. Design, specify, and validate payload interfaces: power supply, signal routing, communication interfaces, connectors, mounting concepts, cooling, grounding and shielding, and serviceability. Enable a payload-flexible vehicle platform that supports a wide range of customer-specific payloads (power profiles, environmental conditions, data interfaces) without major redesigns for every new configuration. Electrical, Electronic and mechanical Integration Integrate payloads into the vehicle power, network, compute, and control architectures: schematics, harnessing, connectors, fusing, diagnostics, and interface documentation. Work with vehicle communication buses (CAN, automotive Ethernet) to bring payload data and control interfaces cleanly into the vehicle architecture. Own the health of the complete E/E system: systematic cross-domain troubleshooting across payload, harness, power, compute, and software. Drive payload mounting together with internal vehicle teams and external suppliers: brackets, packaging, accessibility, vibration robustness, environmental protection, maintainability, and manufacturability. Bring-up, Commissioning and Validation Plan and execute payload bring-up and commissioning on vehicle prototypes and demonstrators: mechanical fitment, electrical integration, software provisioning (flashing, configuration, diagnostics), troubleshooting, and validation up to full system commissioning where the complete E/E system is proven to work. Define acceptance criteria, build and run system-level test setups, automate recurring integration and regression tests with scripts and test tooling, and support field testing. Translate integration findings into design improvements for vehicle and payload interfaces, and feed vali
