We are looking forward to hire System Testing Professionals in the following areas :

Job Description

Experience required: 5+ years.

We need your talent! Client is currently seeking a Senior Software Test Engineer to join our R&D Software team.

Our instruments are pivotal in: Electric Cars, 3D Printing, batteries, recyclable plastics, space suits, candy that melts in your mouth and not your hands, paint that goes on smooth and dries without streaks, and even ensuring your French fries have the perfect crunch to them! Material Science uniquely spans the fields of physics, chemistry, engineering, and manufacturing.

Our instruments and software come together to aid in accelerating the design of new materials as well as the quality of manufacturing those materials.

We’re looking for a passionate Senior Software Test Engineer with a talent for building quality software solutions. We build complex, connected scientific instruments that combine embedded software, Linux-based platforms, cloud services, web applications, and our flagship Windows desktop software (TRIOS). This role sits at the system levelwhere 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, web interfaces, and rich desktop applications, working closely with product, firmware, software, and manufacturing teams.

As a Senior Software Test Engineer, You Will

• Design and execute system-level test strategies for Linux-based IoT, connected instrument platforms, and flagship Windows desktop applications (such as TRIOS).
• Perform manual and automated software testing specifically targeting complex Windows desktop environments and scientific applications.
• Validate end-to-end workflows across device firmware, edge services, backend APIs, web UIs, and desktop clients.
• Perform functional, integration, regression, performance, and reliability testing across the entire software ecosystem.
• 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 desktop 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 & Desktop Focus)

• Develop and maintain automated tests at the system, API, web, and desktop application layers (Python strongly preferred; C# or UI automation tools a plus).
• Integrate automated tests for both embedded Linux systems and Windows desktop applications 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.

Education

• Bachelor’s Degree in computer science or computer engineering preferred, or an equivalent combination of education, training, and experience.

Experience

• 5+ years of experience in system testing, validation, or quality engineering for complex products.
• Experience with manual and automated software testing for Windows desktop-based applications (e.g., TRIOS or similar complex analytical/instrumentation software).
• 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.

Preferred

• Interest or foundational experience working in an analytical instrumentation domain.
• Basic knowledge of Networking and TCP/IP communication.
• Interest in interfacing with embedded devices.
• Experience testing web applications, APIs, and backend services.
• Experience with desktop UI automation frameworks (e.g., WinAppDriver, TestComplete, Selenium).
• 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).

For you, it’s more than a job. Among other things, we’re strong advocates of creating quality software and using the latest testing methodologies to ensure we meet the expectations of our customers.

At YASH, you are empowered to create a career that will take you to where you want to go while working in an inclusive team environment.
