Full 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
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
