Github Jobs in Delaware (NOW HIRING)

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 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

What We're Looking For (MustHave)

• 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
