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.

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 Dev Ops 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, 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)

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
