Your Role

As a Senior Software Engineer in Test, you'll join a multidisciplinary team alongside MRI and Software Engineers to build and own a testing platform for our scanning software. Your mission is to make complex systems testable: microservices, AI inference, MRI workflows, and hardware-adjacent components-reliably, repeatably, and at scale.

This is a hands-on software engineering role. You will design test infrastructure, simulation layers, and CI integrations that enable fast feedback and high confidence releases-from unit tests to end-to-end and system health monitoring.

In this role, you'll play a key part in redefining software testing by delivering high-quality testing solutions.

Your day-to-day

Your responsibilities include:

• Own and evolve the team's testing framework across unit, contract, integration, and end-to-end testing, with a strong emphasis on maintainability and scalability.

• Design and implement simulation tooling (adapters, mocks, stubs, fakes, simulators) to test systems without requiring physical hardware, including: error injection / fault simulation, bypassing hardware dependencies in test mode, and deterministic, reproducible test environments.

• Integrate tests into CI/CD pipelines (gating, quality signals, reporting, flake management) and improve observability for failures using tools like Grafana/Sentry (or equivalent).

• Build contract and integration tests validating microservice communication (RabbitMQ events and/or REST APIs), ensuring message schemas, compatibility, and failure handling remain stable over time.

• Develop E2E/system-level tests for critical workflows spanning AI models, MRI processes, and service orchestration.

• Raise unit test quality via code review: improve test design, coverage meaningfulness, reliability, and maintainability.

• Work closely with the Head of Quality Engineering on strategy, prioritization, and long-term architecture for a future-proof testing ecosystem.

Your experiences and skills Fit to our values

• We own every challenge: we enjoy complexity and thrive under uncertainty.

• We strive for better: we seize any opportunity for growth and challenge the status quo. We are constantly learning and improving.

• We imagine new frontiers: we think beyond 'doable' and 'reasonable.' We design a sustainable and healthy future together.

Experience and skills

• Proficiency in Python, Pytest, Unittest.

• Expertise in designing and implementing mocks, stubs, and fakes with mocking frameworks such as Python's unittest.mock, pytest-mock, or equivalent tools to isolate testing.

• Experience in developing and maintaining scalable testing frameworks and managing CI/CD pipelines.

• Expertise in designing robust architecture while applying best practices in software development.

• Proficiency in working with messaging systems like RabbitMQ or RESTful APIs to design, test, and validate reliable communication between distributed services.

• Strong debugging skills to trace issues.

• Proficiency in designing and implementing unit test and TDD approaches.

We look for people to join us in our journey towards a culture focused on the following principles:

• A friendly environment where collaboration and inclusivity empower everyone to do their best work.

• A commitment to scalability and great testing practices, designing solutions that are robust, efficient, and future-proof.

• The ability to see the big picture while addressing specific needs, balancing strategic thinking with tactical execution.

• A mindset that embraces challenges and does the hard work to eliminate testing bottlenecks and drive innovation.

• The confidence to say "no" when needed and the wisdom to work smarter, not harder, prioritizing impactful solutions.

• Eager to learn.

What makes you stand out from other candidates
