Software Engineer (Test)

Ensera Design is a world-class user‑centred innovation and product development consultancy, specializing in the medical and consumer health sectors with offices in Bristol, Colorado and New Jersey. As part of Ensera, we collaborate globally with contract manufacturing facilities in Europe, the USA, and Asia.

We are currently seeking an Embedded Software Engineer in Test to join our talented team and contribute to delivering exceptional solutions for our clients.

You’ll join a multidisciplinary team developing a greenfield medical device from the ground up.

Day to day, your focus will be building structured testing strategies and processes for embedded systems and shaping the automation approach as it takes its form. You’ll work closely with the embedded, Linux, UI and connectivity teams to make code testable from the start.

You’ll have a team of Senior Software Engineers around you who’ll mentor you throughout. Due to the nature of Ensera Design’s work, you’ll have the opportunity to either branch out into other specialisms or go deeper into the one you’re already in.

About you

You enjoy working on and improving complex safety‑critical systems through designing effective test strategies. You’ll have a strong background in test automation and have a real passion for improving how testing is done in complex engineering environments.

You’ll be a strong collaborator and communicator who’s happy to work closely with developers in C++ and Python environments.

You’ll be interested in the full development lifecycle and in working to standards like IEC 62304.

What you’ll do

• Design and implement test strategies for embedded software
• Build and maintain automated test frameworks
• Contribute to testing approaches for assigned subsystems and interfaces
• Work with development teams to ensure software is testable and verifiable
• Support requirements‑based testing and traceability
• Investigate failures, support root‑cause analysis, and verify corrective actions
• Contribute to continuous integration and automated test execution
• Share knowledge and mentor more junior members of the team

Your skills and experience

You don’t need to tick every box but if you hit most of the essentials, we’d love to hear from you.

• Around 3–5 years’ experience in software testing for embedded and/or Linux‑based systems
• Experience building automated test frameworks and infrastructure
• Understanding of embedded software architectures and constraints
