Job summary

FSO Instruments in the Netherlands is looking for a medior Embedded Software Engineer to help shape the future of space communication. You will contribute to a modular software suite for space-grade optical subsystems, ensuring robust performance from launch to end-of-life.

The role emphasizes embedded C/C++ firmware, deterministic real-time control, hardware bring-up, and rigorous testing in a cross-disciplinary environment, with opportunities to advance in laser satellite communication tech.

Qualifications

• Bachelor's or Master's in Electrical Engineering, Computer Engineering, or related field.
• 5+ years embedded software experience, preferably in space or high-tech environments.
• Strong knowledge of embedded software, RTOS, and low-level programming.
• Proficient in C and C++.
• Experience with UART, SPI, I2C and hardware/software co-design.

Responsibilities

• Firmware Development — develop embedded C/C++ firmware for MCUs, FPGAs, or SoCs controlling optical subsystems.
• Real-Time Control — create deterministic control loops for actuators, gimbals and fine-steering mirrors.
• Hardware Integration — bring-up boards, debug interfaces, and validate revisions.
• Optical Payload Support — drivers and control logic for lasers, detectors, ADC/DAC chains.
• Testing & Verification — unit tests, HIL tests, and environmental testing participation.
• Documentation & Reviews — contribute to ICDs and design reviews.

Job description

Are you a talented Embedded Software Engineer with a passion for space systems and laser communication technology? FSO Instruments, a pioneering space company specializing in laser satellite communication technology, is actively seeking a highly skilled and motivated medior Embedded Software Engineer to join our dynamic team. If you are eager to make a significant contribution to the future of space communication and engage in groundbreaking projects, this is an extraordinary opportunity for you.

About Demcon

FSO Instruments is at the forefront of developing advanced laser satellite communication technology. Together with our partners and shareholders we are committed to strengthening the Dutch space industry and pushing the boundaries of communication systems to enable faster, more reliable, and secure connections between satellites, airplanes, drones and ground stations. By pushing the boundaries of what is achievable, we are shaping the future of space communication, both locally and globally.

What are you going to do?

The software suite under development must seamlessly support a diverse range of optical communication products currently being engineered at FSO Instruments, demanding a highly modular and scalable architecture. Because these systems operate in the harsh and unforgiving environment of space, robustness and resilience are essential design drivers. This places strong emphasis on deterministic behavior, fault tolerance, and reliable performance across all mission phases — from launch to end-of-life.

Typical activities and responsibilities for embedded software engineers at FSO Instruments:

• Firmware Development — Implement and maintain embedded C/C++ firmware for microcontrollers, FPGAs' soft cores, or SoCs that control optical communication subsystems (pointing, acquisition, tracking, modulation control).
• Real-Time Control Systems — Develop deterministic control loops for actuators, gimbals and fine-steering mirrors.
• Hardware Integration — Bring-up of new boards, debugging interfaces (SPI, I2C, UART, CAN, SpaceWire), and validating hardware revisions.
• Optical Payload Support — Implement drivers and control logic for lasers, detectors, ADC/DAC chains, and optical alignment sensors.
• Communication Protocols — Implement and test custom or standardized protocols for inter-module communication and satellite bus interfaces.
• System Diagnostics — Develop telemetry, logging, fault detection, and recovery mechanisms for space-grade reliability. Executing reliability analysis in close collaboration with other disciplines.
• Testing & Verification — Write unit tests, HIL tests, and participate in environmental testing (thermal-vacuum, vibration, radiation considerations).
• Documentation & Reviews — Contribute to design documents, interface control documents (ICDs), and participate in design reviews.

What do you bring to the table?

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related field.
• 5+ years of experience as Embedded Software Engineer or a similar role, preferably in the field of communication technology, space systems or high-tech (semicon).
• Strong knowledge of embedded software, real-time operating systems, and low-level programming.
• Proficiency in programming languages such as C and C++.
• Familiarity with communication protocols and standards used in embedded systems, such as UART, SPI and I2C.
• Experience with microcontrollers, FPGA’s, System-on-Chips, and hardware/software co-design.
• Knowledge of laser communication principles and technologies would be advantageous.
• Excellent problem-solving skills and the ability to work effectively in a collaborative and fast-paced environment.
• A solution-orientated team player with good communications skills.
• You have good command of the English language in word and writing. Good command of the Dutch language is preferable but not mandatory.

What do we offer you?

At FSO Instruments we have a 'flat' organization where people can easily find and help each other. We value a comfortable and inclusive workplace. Furthermore, you can count on, among other things:

• A good, market-based salary;
• 31 days off and 8% vacation allowance;
• Possibility to work from home, maximum 2 days a week.
• A good pension plan at Zwitserleven;
• The opportunity to follow training and courses, or externally, so you can further develop your knowledge;
• A laptop and mobile phone from work;
• Bicycle plan.
