Your day to day

Hardware Emulation & Simulation

• Design and implement software simulators for MRI scanners, sensors, and custom hardware interfaces.

• Develop mocks and stubs that accurately reproduce hardware behavior under edge-case conditions.

Test Framework Development

• Build and maintain reusable shared libraries for test harnesses, data generators, and assertion utilities.

• Embed gRPC client/server mocks to validate inter-service contracts in isolation.

Messaging & State Management

• Integrate Redis and RabbitMQ into test workflows to simulate real-world data flows and stateful scenarios.

• Author test utilities that can spin up and tear down message queues and in-memory data stores on demand.

CI/CD & Pipelines

• Architect and maintain end-to-end test pipelines (e.g. GitHub Actions, Jenkins) that run hardware-emulated and microservice tests.

• Automate environment provisioning (Docker, Kubernetes) for parallel, reproducible test runs.

Collaboration & Best Practices

• Partner with Software Engineer in Test, Software teams to identify high-value scenarios for automation.

• Champion test-driven development, code reviews, and continuous feedback loops.

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.

Technical Expertise

Hardware Emulation Expertise

• Proven ability to write device simulators, hardware mocks, or FPGA/driver emulations in software.

• Deep understanding of low-level protocols (SPI, I²C, custom serial) and how to reproduce them in a test harness.

Passion for Testing

• Test-driven development mindset, with a portfolio of robust unit, integration, and system tests you’ve authored.

• Eagerness to explore failure modes and proactively hunt for edge-case bugs.

gRPC Proficiency

• Design, implement, and mock gRPC services in your language of choice (Python/Go/Java).

• Validate service contracts and error-handling paths with automated tests.

Redis & RabbitMQ

• Hands-on experience using Redis for in-memory state emulation and RabbitMQ (or equivalent) for message-based workflows.

• Ability to script dynamic queue/exchange setups and teardown in tests.

Pipeline & Infrastructure Automation

• Skilled in building CI/CD test pipelines that coordinate multi-stage tests, generate reports, and gate deployments.

• Familiarity with container orchestration (Docker, k3s/Kubernetes) for isolated test environments.

Shared Libraries & Modularity

• Track record of designing and maintaining internal libraries or SDKs that accelerate test development and enforce consistency.

• Strong API design skills to make onboarding and adoption frictionless.

What makes you stand out from other candidates

• You’ve built or contributed to an open-source hardware simulator, testing framework, or tooling that’s widely adopted.

• You’ve led cross-disciplinary efforts to integrate test suites into production CI/CD pipelines at scale.

• You maintain an active blog, talks, or GitHub repos showcasing innovative approaches to test platform engineering.

• You mentor others in testing best practices, from test design to mocking patterns and pipeline reliability.
