Test Validation Engineer

We build complex, connected scientific instruments that combine embedded software, Linux-based platforms, cloud services, and web applications. This role sits at the system level—where real-world device behavior meets software quality—and ensures our platforms are robust, reliable, and ready for production and field use
.

You’ll own system‑level validation across hardware, firmware, backend services, and web interfaces, working closely with product, firmware, software, and manufacturing teams.

• Design and execute system-level test strategies for Linux-based IoT and connected instrument platforms
• Validate end-to-end workflows across device firmware, edge services, backend APIs, and web UI
• Perform functional, integration, regression, performance, and reliability testing
• Test system behavior under real‑world conditions (network latency, device failures, power cycling, upgrades, stress scenarios)

• Test instrument bring‑up, initialization, calibration, and recovery across firmware updates and fault conditions
• Validate operation under environmental and operational stress (temperature, vibration, long‑duration runs)
• Lead and support cross‑disciplinary root cause analysis involving software, firmware, electronics, and mechanical subsystems
• Use logs, telemetry, and lab tools (e.g., multimeter, oscilloscope, logic analyzer) to diagnose complex system issues

• Develop and maintain automated tests at the system, API, and web layers (Python preferred)
• Integrate automated tests into CI/CD pipelines to support continuous quality and release readiness
• Collaborate with Dev Ops and development teams on build verification, deployment validation, and pre‑production testing

• Support manufacturing and service teams by validating system-level test coverage and diagnostics
• Reproduce field and manufacturing issues in lab environments and help drive corrective actions

• 5+ years of experience in system testing, validation, or quality engineering for complex products
• Hands‑on experience with Linux‑based systems
  , embedded platforms, or IoT devices
• Proven ability to validate end-to-end systems spanning hardware and software
• Experience with test automation and scripting (Python strongly preferred)
• Strong troubleshooting and root cause analysis skills across hardware–software boundaries
• Comfort working in a lab environment with physical devices or instruments
• Experience testing web applications
  , APIs, and backend services
• Docker or containerized deployments
• Exposure to cloud‑connected systems (AWS, Azure, or GCP)
• Performance, reliability, or long‑duration system testing
• Observability tools (logs, metrics, traces)

• Ownership of system-level quality for a real‑world, high-impact product
• Close collaboration with firmware, hardware, software, and product teams
• A role where testing is proactive and influential
  , not reactive
• Clear growth path toward senior system or principal‑level engineering roles
