Senior Embedded Systems Test Engineer (All Genders)

STARK; Berlin; On-site; EUR 70,000 - 110,000; Full time

Job summary

STARK in Berlin seeks an experienced Embedded Software Test Engineer to bridge software and hardware, designing robust test suites that push firmware in lab environments.

You will develop automated tests with Python, manage HIL/SIL/MIL simulations, and work with CAN/SPI/I2C protocols and RTOS such as FreeRTOS or Zephyr. The role demands 5+ years in embedded testing or development and strong debugging skills.

Qualifications

• 5+ years of experience in embedded software testing or development.
• Strong programming skills in scripting languages like Python.
• Experience with embedded RTOS (e.g., FreeRTOS, Zephyr) or bare‑metal environments.
• Familiarity with communication protocols: UART, SPI, I2C and CAN.
• Tools: Experience with Git, Jira, and lab equipment (Multimeters, Power Supplies, Debuggers like J‑Link).

Responsibilities

• Test Strategy & Design: Develop comprehensive test plans, cases, and procedures based on functional requirements and design specifications.
• Automated Testing: Design, build, and maintain automated test frameworks and scripts (robotframework/Python).
• Hardware-in-the-Loop (HIL): Configure and operate HIL, SIL, and MIL simulation environments to validate software behavior in real‑world scenarios.
• Debugging & Analysis: Utilize oscilloscopes, logic analyzers, and protocol analyzers (CAN, SPI, I2C) to troubleshoot complex hardware/software interactions.
• Defect Management: Identify, document, and track software defects; collaborate closely with firmware developers to verify fixes and perform regression testing.
• Compliance: Ensure testing processes meet industry‑specific standards (e.g., ISO 26262, IEC 62304, or DO‑178C) where applicable.

Job description

At Stark, we forge the future of European and national security through cutting‑edge, AI‑driven technology and unmatched engineering precision. As a premier defence technology company, our mission is clear: to equip NATO Allies and their partners with next‑generation autonomous defence platforms and advanced AI‑driven software built to perform in the world’s most demanding environments.

We believe that true security stems from relentless innovation. By combining elite engineering talent with agile technology and an AI‑native operational culture, Stark turns complex defence challenges into field‑tested, multi‑domain solutions.

WHY JOIN US

• The software and systems you work on directly protect personnel and defend European and national sovereignty.
• You will work alongside industry‑leading minds on autonomous systems, advanced propulsion, and secure cyber platforms.
• We foster a fast‑paced, collaborative environment where bold ideas are supported by serious R&D backing.

About the Team

We are the architects of the physical experience. As part of our R&D‑driven Electronics Department, our__Embedded Software Team turns visionary ideas into high‑performance technology. In our enthusiastic and high‑energy environment, we have the tools, the talent, and the passion to engineer first‑class products that lead the global market.

Your Mission

You will bridge the gap between software development and hardware integration, designing robust test suites that push our firmware to its limits.
You thrive in the lab and enjoy “breaking” things to make them better, and you have a deep understanding of how software interacts with physical circuitry.

Responsibilities

• Test Strategy & Design: Develop comprehensive test plans, cases, and procedures based on functional requirements and design specifications.
• Automated Testing: Design, build, and maintain automated test frameworks and scripts (robotframework/Python).
• Hardware-in-the-Loop (HIL): Configure and operate HIL, SIL, and MIL simulation environments to validate software behavior in real‑world scenarios.

• Education:Bachelor’s degree in Electrical Engineering, Computer Science, or a related field.
• Experience:5+ years of experience in embedded software testing or development.
• Strong programming skills in scripting languages like Python.
• Experience with embedded RTOS (e.g., FreeRTOS, Zephyr) or bare‑metal environments.
• Familiarity with communication protocols: UART, SPI, I2C and CAN.
• Tools:Experience with Git, Jira, and lab equipment (Multimeters, Power Supplies, Debuggers like J‑Link).

Nice‑To‑Have

• The “Testing Mindset”:A proactive approach to identifying edge cases and potential failure points.
• Adaptability:Comfortable working with evolving hardware prototypes and early‑stage firmware.
• Communication:Ability to translate complex technical bugs into actionable reports for stakeholders.
• Fluent English (C1 preferred). German language skills are advantageous but not required.

SECURITY CLEARANCE

Due to the nature of our work in the defence sector, candidates must be eligible to obtain and maintain the appropriate security clearance required for this position. Details will be provided during the recruitment process.
