Embedded Software Ingenieur

TechSAT GmbH; Kirchheim bei München; On-site; EUR 70,000 - 100,000; Full time

Job summary

TechSAT GmbH is seeking an Embedded Software Engineer to develop safety-critical software for onboard product family, from drivers to real-time platform.

In a small cross-functional team, you will ensure requirements through verification on our test environment, following DO-178C guidance and MISRA C standards.

You will work on interfaces like ARINC 429, CAN FD, RS-485 and contribute to system safety activities.

Qualifications

• Degree in computer science, electrical engineering, aerospace/computing or related field.
• Solid knowledge of microcontrollers or multicore processors and interrupt handling.
• Experience with serial/fieldbus interfaces (CAN, RS-485, ARINC 429) and low-level drivers.

Responsibilities

• Design, implement and test embedded software in C (and C++ where appropriate) on RTOS or bare-metal.
• Develop platform software: BSP, boot/startup, built-in test, health monitoring, safe-state handling.
• Develop drivers and IO handling for avionics interfaces: ARINC 429, CAN FD, RS-485, discrete I/O, sensors.
• Follow DO-178C processes: requirements/design, traceability, MISRA C, reviews, structural coverage.
• Verify software via unit, integration and hardware-in-the-loop tests on ADS2-based test systems.
• Support system safety assessment and hardware/software interface definition with hardware/FPGA teams.
• Maintain source code and build environments under configuration management.

Job description

As an Embedded Software Engineer, you will develop the safety-critical software of our onboard product family, from low-level drivers and the real-time platform to redundancy management and the interfaces to sensors, inceptors and actuators. You will work in a small, cross-functional team of system, hardware, FPGA and test engineers and take responsibility for your software from requirements through verification and integration on the TechSAT test environment.

Your Tasks

• Design, implement and test embedded software for in C (and C++ where appropriate) on a real-time operating system or bare-metal platform.
• Develop the platform software: board support package, boot and startup software, built-in test, health monitoring and safe-state handling.
• Develop drivers and I/O handling for avionics interfaces: ARINC 429, CAN FD, RS-485, discrete I/O, RVDT/LVDT position sensing and Ethernet.
• Develop the software according to DO-178C: software requirements and design, traceability, coding standards (e.g. MISRA C), reviews and structural coverage analysis.
• Verify the software through unit, integration and hardware-in-the-loop tests on the ADS2-based test systems, including fault injection.
• Support the system safety assessment (FHA, FMEA, FTA) and the hardware/software interface definition with the hardware and FPGA team.
• Keep all source code, toolchains and build environments under configuration management and fully reproducible.

Your Profile

Required

• Degree in computer science, electrical engineering, aerospace engineering, computer engineering or a comparable field.
• Solid knowledge of microcontrollers or multicore processors, interrupt handling and low-level drivers.
• Hands-on experience with serial and fieldbus interfaces such as CAN, RS-485, SPI or ARINC 429.
• A structured, well-documented way of working and enjoyment of working in a small team.
• Fluent in technical English communication

Nice to have

• Experience with safety-critical software development, ideally to DO-178C (DAL A to C)
• Experience with requirements-based development and testing, traceability and static analysis or coding standards such as MISRA C.
