Software Engineer - Embedded & Safety-Critical Systems
Location: Cardiff
A newly formed mid-sized technology firm, created through the merger of two established engineering companies (one UK-based, one US-based), is seeking skilled Software Engineers to join their growing team. With a focus on delivering cutting-edge embedded software and hardware solutions, this role offers the chance to contribute to high-integrity systems used in advanced aerospace and defence applications.
About the Role
We're looking for engineers who are passionate about solving complex problems in critical systems. You'll help design and build robust software solutions for highly regulated environments - including avionics systems and submarine control interfaces. You'll work as part of a collaborative, cross-functional engineering team based in either Cardiff or Cheltenham.
Key Responsibilities
1. Develop and maintain real-time embedded software in line with rigorous safety and quality standards
2. Collaborate with hardware, systems, and test engineers to ensure seamless integration
3. Engage in the full software lifecycle, from requirements through to verification and delivery
4. Contribute to internal process improvements and technical best practices
What You'll Need
5. A degree in Computer Science, Software Engineering, Electronics, Mathematics, or a related discipline - or equivalent hands-on experience
6. Proficiency in at least one of the following: C or C++
7. Exposure to any of the following is highly desirable: RTOS, VXWorks, Ada, DO-178, device driver development, or embedded display technologies
8. Embedded systems experience is a plus, but not essential
9. Familiarity with safety-critical environments is advantageous
Why Join Us?
This is an opportunity to work in a flexible, low-bureaucracy environment that values productivity, transparency, and mutual trust. We've taken the best parts of both large-scale and agile companies to create a workplace where engineers can do meaningful work while maintaining a healthy work-life balance.
What We Offer
10. A strong emphasis on work-life balance and employee autonomy
11. Involvement in highly respected defence and aerospace programmes
12. Supportive, down-to-earth company culture
13. Long-term professional development
