Software Test Engineer

Senior SDET - Test Automation (Devices)

Location: London

Type: Contract

Duration: 6 months (high potential for extension or conversion)

Work Setup: Hybrid - minimum 3 days on-site, 5 days preferred

Project Overview

Join a medical device software development program focused on AI-driven operating room technologies and video data processing systems. You'll test and automate complex applications running on low-latency, high-performance computing platforms used in surgical environments.

Role Summary

An automation-first quality culture, where software quality is built through code. As a Software Development Engineer in Test (SDET), you'll design, develop, and maintain automated test solutions for embedded and connected device platforms. This role requires a hands-on engineer with strong Python automation expertise and experience in systems-level testing beyond traditional web or mobile environments.

Key Responsibilities

• Design, develop, and maintain robust, reusable test automation frameworks for device software.
• Collaborate with developers to define testable architectures and embed quality throughout the SDLC.
• Create and execute advanced test strategies for embedded platforms (Linux, Android, IoT).
• Develop test plans and protocols for APIs (REST, IPC), web interfaces, and OTA updates.
• Integrate automated testing into CI/CD pipelines (Jenkins, GitHub Actions, Azure DevOps).
• Support manual testing activities when required and promote automation best practices.
• Produce and maintain technical documentation and standards for automation and quality engineering.

Technical Competencies

• Strong proficiency in Python (critical requirement).
• Solid experience with test automation frameworks (e.g., PyTest, Selenium, Appium, or equivalent).
• Familiarity with Linux, real-time systems, and interprocess communication (IPC).
• Experience testing:
• Device OS (Android, Linux)
• APIs (REST, IPC) and service-oriented architectures
• Web-based interfaces and Internet-connected devices
• Video data or streaming systems (advantageous)
• Knowledge of CI/CD pipelines and version control systems (Git).
• Experience with performance, reliability, and system-level testing.
• Beneficial: Familiarity with medical device software standards (IEC 62304).

Profile & Experience

• Bachelor's degree in Computer Science, Engineering, or equivalent.
• 3+ years' experience in SDET, automation, or software engineering roles.
• Proven ability to design and implement automation solutions (not just execute manual tests).
• Self-starter with strong problem-solving, technical leadership, and collaboration skills.
• Broad testing experience-beyond web and mobile automation-is essential.
• Prior exposure to medical devices, AI, or high-performance computing is a strong plus.

Nice-to-Have

• Familiarity with BDD tools (e.g., Behave, Cucumber).
• Background in AI or computer vision testing.
