Embedded Software Engineer Aerospace & Defence (m/w/d)

ROLLE Hive Robotics is building Europe's first full-stack orchestration platform for unmanned systems, connecting, controlling, and commanding multi-vendor drone and robot swarms across air, land, sea, and space. Our RF communication systems are Made in Germany, deployed on active frontlines, and targeting a 5 billion EUR European tactical communication market with no sovereign alternative today. We are now looking for an Embedded Software Engineer who joins our distinguished software team developing the embedded software that powers the radio and communication backbone of our systems. Our current focus is our RF communication module family for unmanned systems, in serial production and scaling fast. You will work at the intersection of embedded software, RF, and networking, building production-grade firmware for ARM-based radio modem hardware and shaping our next generation of Software Defined Radio platforms. This is not a maintenance role. You design. You build. You ship. You will work directly with our hardware engineers, RF engineers, and firmware architects, and your work will run in systems that operate in demanding, jamming-resistant field environments where reliability is non-negotiable. VERANTWORTLICHKEITEN * Design, develop, and maintain embedded firmware for ARM-based microcontrollers in production radio modem hardware. * Integrate, configure, and optimize RTOS environments (Zephyr preferred, or FreeRTOS). * Design, implement, and debug low-level networking protocols, including custom Layer 2 (MAC) and Layer 3 (IP/TCP/UDP) functionality. * Develop secure bootloaders, firmware integrity mechanisms, and robust remote firmware update solutions over Ethernet/IP networks. * Perform board bring-up, BSP development, and platform customization for ARM-based systems, including low-level peripheral drivers and hardware abstraction layers. * Contribute to the architecture and development of next-generation SDR and wireless communication platforms. * Analyze and optimize system performance, memory utilization, latency, and power consumption. * Investigate and resolve complex issues using debuggers, oscilloscopes, protocol analyzers, and network diagnostic tools. * Establish and maintain automated verification, testing, and CI/CD pipelines for embedded and Linux-based software. * Collaborate closely with hardware and RF engineers during system integration, validation, and troubleshooting, and contribute to code reviews and software quality standards. ANFORDERUNGEN Must-Have Qualifications * Degree in Embedded Systems, Computer Engineering, Electrical Engineering, or a related field. * Proven track record delivering production-grade embedded firmware. * Strong hands-on experience with ARM Cortex-M and/or Cortex-A platforms. * Excellent C/C++ skills for embedded systems. * Experience with Zephyr (preferred) or another RTOS (FreeRTOS, ThreadX). * Solid understanding of embedded TCP/IP and Ethernet-based communication. * Experience developing bootloaders and secure update mechanisms. * Comfortable with JTAG/SWD debugging and hardware bring-up. * High degree of ownership and the ability to collaborate effectively across disciplines. * Excellent communication skills in English; German is a plus. * Based in Munich or willing to relocate. Nice-to-Have Qualifications * Embedded Linux development experience, including Yocto/PetaLinux build systems. * Hands-on experience with Xilinx Zynq or Zynq UltraScale+ MPSoC platforms. * Familiarity with Linux kernel configuration, device trees, bootloaders (U-Boot), and driver development. * Experience debugging Linux-based embedded systems using JTAG, GDB, kernel logs, and performance analysis tools. * Understanding of Linux networking internals and TCP/IP stack implementation. * Experience with high-speed interfaces such as JESD204 and LVDS in FPGA/SoC-based systems.

DEINE MISSION As part of our Avionics & Software team in Munich, you will help define and mature the avionics and electrical systems of our spacecraft platforms. You will translate mission and spacecraft-level needs into clear requirements, interfaces and equipment decisions. Working closely with our Systems Architects and specialist teams in electronics, embedded software and controls, you will ensure that avionics equipment and subsystems form a coherent and verifiable overall system. This is a systems engineering role with a strong technical focus. You are not expected to be the implementation expert for every avionics domain. Your role will include * Define, manage and maintain spacecraft avionics and electrical system requirements. * Coordinate interfaces between spacecraft equipment, electronics, embedded software, control systems and higher-level spacecraft functions. * Support avionics architecture development together with Systems Architects and technical specialists. * Perform and document equipment and make-or-buy trade studies, for example for OBCs, PCDUs, solar arrays, sensors, communication equipment and remote I/O. * Translate selected equipment into clear electrical, data and software interface requirements. * Develop and maintain interface control documents, architecture descriptions and verification concepts. * Coordinate technical topics with suppliers and assess compliance, development status, risks and open points. * Support proposal activities through requirements analysis, preliminary architectures, supplier inputs, effort estimates and technical risk assessments. * Support subsystem and spacecraft-level integration, verification and troubleshooting. * Contribute to MBSE models and continuously improve our systems engineering processes. DEIN PROFIL * Several years of experience in spacecraft avionics, electrical systems or a comparable safety-critical engineering environment. * Experience in requirements engineering, interface definition and technical trade studies. * Broad understanding of spacecraft avionics and electrical equipment, without the expectation of being a specialist in every domain. * Ability to work effectively with electronics, software, controls and systems engineering teams. * Experience working with suppliers and evaluating technical proposals or equipment. * Familiarity with verification planning, integration testing and relevant systems engineering standards such as ECSS. * Strong analytical and communication skills, with a structured and accountable way of working. * Motivation to develop systems for space logistics and orbital servicing. Nice to have * Experience with spacecraft power systems, data handling, sensors or communication equipment. * Experience with MBSE tools and methods. * Familiarity with SiL, HiL or spacecraft system integration. * Experience with autonomous spacecraft, RPOD or fluidic systems. WIR BIETEN * Immediate and flexible start * Permanent full-time position * 30 days annual vacation and flexible working hours * Attractive salary package * Bike leasing, subsidy for EGYM Wellpass and for the Deutschlandticket * Complimentary beverages, company events and professional development opportunities
