Senior System Test & Validation Engineer

Overview

Why This Role Matters

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 DevOps 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

• •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
