Senior Embedded Linux / SDR Engineer

About MITS Industries

MITS Industries is establishing an R&D and design site in Copenhagen focused on advanced RF systems, signal intelligence, aerospace technologies, and mission-critical product development.

The site will build core engineering capabilities in RF and microwave hardware, antenna systems, RF testing and characterization, rugged mechanical integration, and the industrialization of complex radio-electronic systems.

The Copenhagen team will work closely with strategic partners and engineering teams across Europe, playing a leading role in the development, validation, and industrialization of advanced technologies for defense, aerospace, and other demanding applications.

One of the initial focus areas will be the development of an advanced aerospace signal intelligence product platform. The work will cover RF and system architecture, antenna system design, signal acquisition, embedded control, laboratory validation, mechanical integration, integration with the satellite platform, and preparation for production and field deployment.

The ambition is to build a strong technical design site capable of taking complex RF products, modules, and platforms from architecture and detailed design through prototyping, testing, validation, industrialization, and deployment.

About the role

MITS Industries is looking for a Senior Embedded Linux / SDR Engineer to join the core Copenhagen R&D team and develop the embedded software platform for advanced RF and radio-electronic systems.

You will work at the boundary between hardware and software, developing Linux-based embedded functionality for data acquisition, device control, diagnostics, networking, system services, and SDR integration. The work covers C development and, where applicable, C++, low-level hardware interfaces, Linux drivers and userspace components, high-throughput data handling, performance optimization, test utilities, and deployment of reliable production-ready embedded platforms.

You will work closely with RF and microwave hardware engineers, FPGA and signal processing engineers, systems engineers, test engineers, and partner engineering teams. You will integrate embedded software with RF hardware, SDR components, signal acquisition chains, control interfaces, diagnostics, and higher-level system integration layers.

The role requires strong hands-on experience with Embedded Linux, C, hardware-software integration, and debugging of complex systems. You will contribute to software architecture, platform bring-up, integration strategy, development workflows, and the transition from early prototypes through laboratory validation, field testing, and production release.

Key responsibilities

• Develop and maintain embedded software for Linux-based RF and radio-electronic systems.
• Implement low-level and performance-critical software primarily in C, with C++ where appropriate, including userspace services, hardware-abstraction components, device interfaces, and Linux drivers where required.

• Integrate embedded software with RF hardware, SDR platforms, FPGA and SoC components, signal-acquisition devices, control electronics, and laboratory test setups.
• Develop control, configuration, telemetry, health-monitoring, fault-reporting, and diagnostic interfaces for RF modules and system components.
• Implement signal-acquisition and data-handling pipelines, including high throughput streaming, buffering, timestamping, synchronization, recording, and logging.
• Optimize throughput, latency, boot time, CPU and memory usage, system stability, and long-term reliability.
• Develop and maintain embedded Linux build, packaging, and deployment workflows using Yocto, Buildroot, OpenWrt, or equivalent platforms.
• Implement networking and communication components using TCP/IP, UDP, message-based protocols, and device-control APIs.
• Develop test utilities, service tools, logging functions, and diagnostic capabilities supporting hardware bring-up, integration, validation, and field testing.
• Support integration with automated RF test setups and system-level verification workflows.
• Debug complex hardware-software interactions using tools such as gdb, Valgrind, perf, system tracing, logic analyzers, oscilloscopes, and other laboratory equipment.
• Contribute to embedded software architecture, interface definitions, coding practices, documentation, code reviews, and configuration management.
• Support production release, software deployment, update and recovery mechanisms, and transfer of validated software platforms to manufacturing and integration partners.
• Collaborate closely with RF and microwave hardware, FPGA and signal-processing, systems engineering, Test & Characterization, mechanical design, manufacturing, and partner engineering teams.

Required qualifications and experience

• Bachelor’s or Master’s degree in computer engineering, computer science, electrical or electronic engineering, telecommunications, or a related field.
• 7+ years of professional experience developing embedded software for Linux-based systems.

• Experience with embedded Linux build systems such as Yocto, Buildroot, OpenWrt, or equivalent platforms.
• Experience with software build and configuration tools, including Make, CMake, cross-compilation toolchains, Git, and continuous-integration workflows.
• Strong understanding of TCP/IP, UDP, sockets, network configuration, communication protocols, and network diagnostics.
• Experience developing multithreaded and concurrent software, including synchronization, resource management, and prevention of race conditions and deadlocks.
• Experience optimizing embedded software for throughput, latency, CPU load, memory usage, startup time, and long-term stability.
• Demonstrated ability to diagnose complex hardware-software integration issues using logs, tracing, debuggers, profiling tools, and laboratory equipment.
• Experience creating clear software architecture, interface, build, deployment, and troubleshooting documentation.
• Ability to communicate technical findings clearly and collaborate effectively with hardware, FPGA, RF, test, and systems-engineering teams.
