We’re looking for a Senior Test Design Engineer (or above)

to serve as a technical linchpin for our growing UK team. This isn't just about passing or failing—it’s about designing the systems that ensure excellence from concept to launch.

Your Day-to-day Impact

• Architect Innovation: Develop cutting-edge test concepts and designs using the industry’s best tools.
• Full-Spectrum Ownership: Lead design creation, analysis, and verification across the entire product lifecycle.
• Collaborative Leadership: Partner with cross-functional teams to bridge the gap between "it works on paper" and "it thrives in the real world."
• Drive Efficiency: Champion a Lean Sigma culture, hunting down waste and optimizing processes like a pro.
• Documentation Excellence: Ensure every project is backed by comprehensive, high-quality documentation that meets rigorous standards.

The Essentials

• The Credentials: A Bachelor’s degree in Electrical or Mechanical Engineering (or a related field).

The Experience: 10+ years in test design engineering. You’ve been around the block, and you know where the potholes are.

The Toolkit: Mastery of LabVIEW and TestStand is a must.

The Expertise: Proven success with automated test systems, functional testing, and environmental stress testing.

The Mindset: A black-belt-level grasp of Lean Sigma principles and a commitment to continuous improvement.

Bonus Points For

• A natural ability to build strong relationships with both team members and customers.
• Expertise in structured design and a "cross-discipline" vocabulary.
• A love for the lab—comfort with high-end measurement equipment and diagnostic tools.
