Job description

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.
Responsibilities
What You'll Do
System-Level Testing & Validation
  • 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)
Hardware-Software Integration
  • 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
Automation & CI/CD (System Focus)
  • 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

Manufacturing & Field Support (Collaboration-Oriented)
  • 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

Qualifications
What We're Looking For (Must-Have)
  • 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

Strong Plus (Not Required)
  • Experience testing web applications, APIs, and backend services
  • CI/CD pipeline integration (Jenkins, GitHub Actions, GitLab CI, Azure DevOps)
  • 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)

What You'll Get
  • 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
