Software Development Engineer in Test (SDET) – Unity

Proactively look for ways to make manual testing faster and more reliable — e.g. using capture, instrumentation, and AI-assisted tooling to streamline execution and the recording of results and defects, particularly in hard-to-automate areas such as real-device XR, rather than treating hands-on testing as a fixed overhead.

Execute test cases where automation is not yet built out or suited to automation (e.g. real-device spatial/AR interactions).

Validate application functionality, user workflows, UI behaviour, and overall user experience.

Reproduce, document, and verify defects.

Support release validation and user acceptance testing activities.

Act as a technical bridge between Unity developers and the QA function — working with developers to expose low-level implementation detail (state, internals, hooks) that is currently invisible from outside the application, so that QA can meaningfully test against it.

Champion QA involvement upstream in the design process — engaging early enough to call out testability and quality risks before they're built in, rather than discovering them at test time.

Help shape user stories and acceptance criteria so QA-relevant information is present by the time work enters delivery — e.g. edge cases, testability constraints, and non-functional considerations captured as stories are written, not retrofitted afterwards.

Review requirements and acceptance criteria to ensure they are testable and complete.

Participate in Agile ceremonies including sprint planning, reviews, and retrospectives.

Contribute to test plans, quality standards, and testing best practices.

Continuously improve automation coverage, testing processes, and quality reporting.

Actively champion the adoption of AI tooling within QA and testing workflows — identifying where AI can meaningfully accelerate test generation, test maintenance, defect triage, or reporting, and driving adoption of these practices across the wider QA/engineering team rather than treating this as a one-off initiative.

3+ years' experience in a Software Testing, QA Automation, or SDET role.

Strong C# development skills with experience designing, building, and maintaining automated test frameworks using C# and modern testing practices.

Strong hands-on experience developing or testing applications in Unity, including use of the Unity Test Framework, Play Mode testing, and Edit Mode testing.

Demonstrated ability to build custom test tooling or simulation/harness solutions from scratch — not just configure existing frameworks — particularly for scenarios where standard simulators or test doubles don't reflect real-world behaviour.

Knowledge of Unity performance and memory profiling.

Experience using Jira, Azure DevOps, or similar test management tools.

Experience performing structured manual testing.

Strong understanding of software testing principles and Agile development practices.

Experience using Git and modern development workflows.

Strong cross-functional communication skills, with a track record of translating between engineering implementation detail and QA/testing needs — this role requires working closely enough with developers to influence how testability is built into the application itself, not just testing it after the fact.

Comfort engaging in design discussions and backlog refinement/story-writing, not just testing finished work — able to spot and articulate quality or testability risks early enough to influence how a story or design is written.

A proactive mindset focused on quality, with strong analytical, troubleshooting, and problem-solving skills.

Excellent communication and stakeholder collaboration skills.

Experience testing AR, VR, or mixed reality applications.

Practical experience using AI tools to improve QA or engineering workflows — e.g. AI-assisted test generation, code review, or defect triage — or a track record of driving adoption of new tooling/process more broadly.

Experience testing outside the game engine layer — API, backend, or data integrity testing against services such as a CMS.

Experience with Azure DevOps, GitHub Actions, Jenkins, or similar CI/CD tools.

Experience working within regulated environments, such as healthcare.
