Senior System Test & Validation Engineer

Senior System Test & Validation Engineer

Req. # 25592 | Job Family: DE – Development Engineering |

Location:

US-DE-New Castle | Pay Range: USD $92,000 – $153,000

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.

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 (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 Dev Ops and development teams on build verification, deployment validation, and preproduction 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.

• 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.
• CI/CD pipeline integration (Jenkins, Git Hub Actions, Git Lab CI, Azure Dev Ops).
• 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.
