Embedded Software Engineer (m/f/d)

ATMOS Space Cargo GmbH; Verwaltungsverband Rheinmünster-Lichtenau; On-site; EUR 70,000 - 110,000; Full time

Job summary

ATMOS Space Cargo GmbH is seeking an Embedded Software Engineer (m/f/d) to develop firmware for avionics and to define interfaces with the hardware it controls. You will work across electrical, mechanical, and systems teams from requirements through board bring-up, testing, and documentation.

Responsibilities include developing software for microcontroller-based systems, creating interfaces (CAN, SPI, I2C, UART), writing drivers and bootloaders, and performing hardware-in-the-loop tests with lab

Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Electronics, Computer Engineering, or a related field.
• 5+ years of professional experience developing embedded software for custom electronic hardware.
• Strong programming skills in C and C++ on resource-constrained microcontroller platforms.
• Ability to read and review schematics and to reason about analog and digital circuits.
• Experience with board bring-up and hardware debugging using oscilloscopes, logic analyzers, and JTAG or SWD debuggers.
• Very good written and spoken English; German is a strong plus.
• EU nationals only (candidates must be nationals of an EU member state).

Responsibilities

• Develop embedded software and firmware for microcontroller-based systems from requirements through testing and release.
• Define and implement interfaces between embedded software and electronic hardware (sensors, actuators, CAN, SPI, I2C, UART).
• Write and maintain low-level drivers, BSPs, and bootloaders for custom hardware.
• Bring up new boards and debug hardware and software with lab instruments.
• Plan and run unit, integration, and hardware-in-the-loop tests and maintain documentation.

Job description

ATMOS Works is seeking an Embedded Software Engineer (m/f/d) with strong hands-on experience at the boundary between firmware and electronic hardware. In this role, you will develop the embedded software running on our avionics and define how it interfaces with the hardware it controls, staying involved in the electronics design down to PCB level. Working closely with electrical, mechanical, and systems engineering, you will take ownership from requirements through board bring-up, testing, and documentation.

Key Responsabilities

• You will develop embedded software and firmware for microcontroller-based systems, from requirements through testing and release.
• You will define, document, and implement the interfaces between embedded software and electronic hardware, including sensors, actuators, and communication buses such as CAN, SPI, I2C, and UART.
• You will write and maintain low-level drivers, board support packages, and bootloaders for custom hardware.
• You will bring up new boards and debug hardware and software together in the lab using oscilloscopes, logic analyzers, and debuggers.
• You will plan and run unit, integration, and hardware-in-the-loop tests, and maintain the corresponding technical documentation.

Requirements

• Bachelor's or Master's degree in Electrical Engineering, Electronics, Computer Engineering, or a related field.
• 5+ years of professional experience developing embedded software for custom electronic hardware.
• Strong programming skills in C and C++ on resource-constrained microcontroller platforms.
• Ability to read and review schematics and to reason about analog and digital circuits.
• Experience with board bring-up and hardware debugging using oscilloscopes, logic analyzers, and JTAG or SWD debuggers.
• Very good written and spoken English; German is a strong plus.
• Please note that we can only consider applicants for this position who are nationals of an EU member state.*

Preferred Qualifications

• Experience in space, aerospace, defense, or other high-reliability systems.
• Experience with real-time operating systems and hardware-in-the-loop test setups.
• Knowledge of EMC-compatible design, grounding, and shielding.
• Experience with Python for test automation and data analysis.

Company description

ATMOS Works is a dedicated business unit of ATMOS Space Cargo, based in Kraków, with a business unit in Lichtenau, established to serve European government and defence customers. ATMOS Works develops and operates dual-use orbital capabilities, including the secure, sovereign return of sensitive hardware and data, in-orbit demonstration and validation (IOD/IOV), and advanced space systems.

ATMOS was founded as a European company built on the values of freedom, democracy, equality, the rule of law, and human rights. We are committed to protect these values by making our technology available to others who share the same values, strengthening infrastructure and innovation for prosperity on Earth.

Our team is multinational and diverse, with offices in Lichtenau and Strasbourg. We work in a collegial, hands-on culture where people support each other, take ownership, and keep learning every day. Motivation for the mission comes first — building spacecraft is not a nine-to-five pursuit. We align the mission, the team, and the individual in mutual dependence. This principle shapes our work environment where exceptional people, as committed as they are competent, can grow and contribute to a mission that matters.
