About The Position

We are seeking a Senior System and Software Test Engineer to validate and assure the quality of complex system software spanning scientific instruments and full web application stacks. This role emphasizes system-level testing, automation, and CI/CD integration, and works closely with Product teams to deliver robust, scalable, and secure analytical instrument platforms. Typical tasks of the position include, but are not limited to Design, develop, and execute system-level test strategies for Linux-based IoT platforms, integrating embedded software, backend services, and web applications Validate end-to-end workflows across device firmware, edge services, cloud/backend APIs, and web UI Perform functional, integration, regression, performance, scalability, and reliability testing Test system behavior under real-world conditions (network latency, device failures, power cycling, upgrades, and stress scenarios) Test instrument bring-up, initialization, calibration, and recovery sequences across power cycles, firmware updates, and fault conditions. Verify system behavior under environmental and operational stresses (temperature variation, vibration, long-duration runs, and high-duty cycles) Lead and support cross-disciplinary root cause analysis involving software, electronics, firmware, and mechanical components Diagnose complex issues spanning Linux OS, embedded controllers, electronics, and mechanical subsystems Use logs, telemetry, oscilloscopes, logic analyzers, and other diagnostic tools to isolate hardware–software interaction issues Reproduce field and manufacturing issues in lab environments and drive corrective actions Support manufacturing test strategies by validating system-level test coverage and automation readiness Assist with serviceability and diagnostics validation , ensuring issues can be effectively detected and resolved in the field Develop and maintain automated test frameworks for system, API, and web layers Integrate automated tests into CI/CD pipelines to enable continuous quality Drive increased test coverage at the system and service-interaction level , beyond unit testing Collaborate with DevOps to support build verification, deployment validation, and release readiness Validate containerized and non-containerized deployments (e.g., Docker-based services on Linux) Monitor test results from CI pipelines and provide rapid feedback to development teams Support troubleshooting of system issues in development and pre-production environments The successful candidate will have a combination of knowledge, skills, and experience that would include the following

Requirements

5+ years of experience in system software testing or system validation for complex products combining software, electronics, firmware, and electromechanical subsystems
Strong hands-on experience testing Linux-based systems and IoT platforms , including hardware–software integration
Proven ability to test web application stacks (UI, APIs, backend services) and validate end-to-end system workflows
Proficiency in test automation and scripting (Python preferred) and integration with CI/CD pipelines
Demonstrated skill in troubleshooting and root cause analysis across software, embedded controllers, electronics, sensors, and motion-control subsystems
Comfortable working in a lab environment with analytical instruments, using diagnostic tools (logs, telemetry, multimeter, oscilloscope)

Nice To Haves

Experience with CI/CD pipelines (e.g., Jenkins, GitLab CI, GitHub Actions, Azure DevOps)
Experience with IoT platforms, edge devices, or connected instruments
Familiarity with containerization (Docker, Kubernetes concepts)
Experience with cloud-connected systems (AWS, Azure, or GCP – at a functional level)
Exposure to performance, load, or reliability testing in distributed systems
Knowledge of observability tools (logs, metrics, traces) for test and failure analysis

Diagnose complex issues spanning Linux OS, embedded controllers, electronics, and mechanical subsystems
Use logs, telemetry, oscilloscopes, logic analyzers, and other diagnostic tools to isolate hardware–software interaction issues
Reproduce field and manufacturing issues in lab environments and drive corrective actions
Support manufacturing test strategies by validating system-level test coverage and automation readiness
Assist with serviceability and diagnostics validation , ensuring issues can be effectively detected and resolved in the field
Develop and maintain automated test frameworks for system, API, and web layers
Integrate automated tests into CI/CD pipelines to enable continuous quality
Drive increased test coverage at the system and service-interaction level , beyond unit testing
Collaborate with DevOps to support build verification, deployment validation, and release readiness
