What will you do as a Software Development Engineer in Test (SDET)?

As an Software Development Engineer in Test, you operate at the intersection of software development and quality engineering. You design and build high-quality test infrastructure and automation in the same way developers build production systems. With your strong programming skills in C++and/or Python, you ensure software is testable, scalable, and reliable by design. You work closely with software engineers on complex high-tech systems, contributing directly to codebases, test architecture, and continuous integration pipelines. Rather than only validating software, you actively shape how it is built and verified.

Your responsibilities as a Software Development Engineer in Test (SDET):

• Design, develop, and maintain test frameworks and automation tooling using C++ and/or Python
• Contribute to production code and testability improvements in collaboration with software engineers
• Develop automated tests across multiple levels (unit, integration, system) as part of the development process
• Build and optimize CI/CD pipelines and test infrastructure to enable fast and reliable feedback
• Analyze complex systems and failures, and trace issues to root cause in code
• Drive testability, observability, and quality-by-design principles within development teams
• Work on high-tech systems (embedded / hardware-software integration / distributed systems) with real-world impact
• Take ownership of technical decisions around test architecture and tooling
• Continuously improve automation strategy with a strong focus on engineering scalability and maintainability

What do we offer you?

This will make you smarter:

• Challenging and interesting projects in different domains
• Benefit from the expertise of your technical buddy and more than 100 smart colleagues
• Focus on guiding and coaching on personal development to achieve your ambitions
• Annual study budget and customized training program within our TOPIC Academy
• Tech events and knowledge sessions

This will make you better:

• Permanent contract
• An all-in employment package between €57,000 and €76.000 (including net expense allowance, mobility package, 13th-month bonus, and holiday allowance). Final salary is based on relevant work experience and level of expertise
• 26 vacation days (opportunity to buy extra days), pension scheme and relocation budget (when you relocate to the Netherlands)

This will keep you healthy:

• A good work-life balance, flexible working hours and hybrid way of working
• An inspiring office environment with daily fresh fruit and a gym
• The home office support package will turn your “home office” into an inspiring environment
• Lots of fun during events like celebrations, sport activities and the weekly Friday afternoon drinks

What do you bring as a Software Development Engineer in Test (SDET)?

• A Bachelor's or Master's degree in Computer Science, Embedded Systems or similar
• 5 years of work experience in the high‑tech domain
• Experience with programming in Python, C++ and/or C# and familiar with applying OO principles.
• Hands‑on experience with test automation
• Preferably experience with the ROBOT Framework and methodologies such as TDD, BDD, keyword‑driven testing, data‑driven testing, model‑based testing, and property‑based testing
• You are a team player, solution-oriented, and proactive
• A good command of English, and preferably Dutch language
