We’re looking for people who want to be part of something being built from the ground up, who enjoy the momentum and responsibility that comes with it and who bring commitment, curiosity and teamwork to everything they do.

We’re looking for an exceptional Q&A Test Engineer to join our team building cutting‑edge Runtime Assurance systems for AI and robotics applications. You will play a vital role in developing the safety‑critical embedded software components that ensure the safe and reliable operation of our solutions.

SAIF Autonomy offers a competitive compensation package, excellent benefits and the opportunity to work on cutting‑edge technologies that shape the future of AI and robotics safety.

• Lead the design, development and implementation of embedded software for SAIF Systems’ Runtime Assurance platform across various hardware architectures and real‑time operating systems.
• Ensure compliance with industry standards, regulations and best practices for safety‑critical software development, such as DO‑178C, ISO 26262 and IEC 61508.
• Build configuration and pipeline management.
• Software‑in‑the‑Loop and Hardware‑in‑the‑Loop including automated deployment across multiple platforms.
• Integration of different performance testing techniques across multiple types of simulation (gazebo sim, rosbag).
• Collaborate with cross‑functional teams, including hardware engineers, systems architects and AI/ML experts, to integrate embedded software components seamlessly into the overall system.
• Participate in code reviews, performance optimisations and thorough testing (unit, integration, and system‑level) to maintain the highest quality standards.
• Contribute to the continuous improvement of the team’s software development processes, tooling and methodologies.

• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering or a related field. Or equivalent experience, with a strong focus on embedded systems QA and software development and/or testing.
• Experience with one or more CICD pipeline services (Jenkins, Cloud Build, AWS Code Pipeline, etc).
• Experience with infrastructure/Automation techniques (bash, python).
• Knowledge of source control (git).
• Experience with at least one test framework (pytest, gtest).
• Hands‑on experience in embedded software testing and QA, with a proven track record in delivering safety‑critical systems.
• Solid understanding of software development methodologies, such as Agile, Continuous Integration, and Test‑Driven Development.
• Develop, implement and execute test strategies and verification activities for safety‑critical software.
• Perform static and dynamic code analysis using industry tools (e.g., Rapita RVS, LDRA, Vector
  
  CAST, Polyspace).
• Support compliance with safety standards (e.g., DO‑178C, ISO 26262, IEC 61508, DEF STAN 00‑55) through rigorous testing and documentation.
• Define and maintain test cases, procedures and automation frameworks to ensure consistency and repeatability.
• Collaborate closely with software engineers, systems engineers and safety teams to ensure test coverage against requirements.
• Lead defect reporting, tracking and resolution through structured QA processes.
