Senior Firmware Test Engineer

We are looking for a Senior Firmware Test Engineer to lead and participate in the creation and execution of test strategies for embedded firmware in top-tier Pressure and Temperature field instruments, known for delivering precise and reliable measurements across various industries. In collaboration with engineers from multiple global locations, the role involves analyzing diverse requirement sources like software requirement specifications, interface specs, data dictionaries, and command specs to develop structured test designs, automate implementations, and conduct test campaigns using our Azure Dev Ops infrastructure.

You will interact with products through communication interfaces such as HART instead of modifying product firmware directly.

• Analyze and interpret multiple requirements sources (SRS, interface specs, data dictionaries, command specs) to develop comprehensive, traceable test designs
• Design, implement, and maintain automated test cases that interact with the product through HART and other communication interfaces
• Execute and manage test campaigns within Azure Dev Ops, including test plans, test runs, and results reporting
• Develop and refine test strategies for test automation (~90%) and manual testing (~10%), contributing to overall test architecture alongside the team lead
• Investigate test failures to isolate root cause between the test system, test script, and product behavior—escalating confirmed product issues to the firmware team with clear, reproducible evidence
• Participate actively in formal peer reviews of test designs and implementations, both as a reviewer and as an author presenting work for review
• Maintain rigorous documentation and traceability practices
• Collaborate closely with firmware developers to understand product behavior and ensure test coverage aligns with product risk and requirements
• Drive test planning across the full product lifecycle: requirements, design, validation, release, and post-release support
• Identify and drive continuous improvement in test processes, automation frameworks, and validation methodologies
• Provide technical mentoring and guidance to other test engineers as needed, supporting the team lead in work direction and coaching
• Work in an agile development environment using Azure Dev Ops

You step up to handle tough issues. You stage activities with relevant milestones and schedules. You provide clear direction and accountabilities. You effectively handle risk. You create a plan and outline for various audiences.

• Bachelor's Degree in Engineering or Computer Science
• Minimum of five (5) years of related experience
• Legal authorization to work in the United States - sponsorship will not be provided
• Willingness to occasionally meet with global team members during off hours
• Experience developing automated tests in C# or similar object-oriented language
• Knowledge and experience with agile development methodologies

• Engineering degree from an ABET-accredited school or Masters degree
• Experience working in geographically distributed teams
• Experience developing and executing tests within a CI/CD or Dev Ops-based test infrastructure
• Experience with Azure Dev Ops (test plans, pipelines, work items) or similar test management tools
• Experience testing embedded or firmware-based products through external communication interfaces (e.g., HART, fieldbus protocols)
