Responsibilities
Design, develop, and implement software functionality – Create and deliver software that meets system and customer requirements while respecting industry best practices, cost targets, and technical constraints
Develop and integrate embedded SW for microcontroller‑based hardware – Apply solid software engineering skills to design, code, and test firmware while performing hands‑on hardware activities such as bench‑level debugging, hardware‑software integration, and peripheral configuration on microcontrollers and associated circuitry. This responsibility ensures that the candidate can bridge software development with real‑world hardware implementation to deliver reliable, high‑performance embedded solutions
Develop software requirements – Elicit, define, and document functional and non‑functional requirements; lead the creation and validation of requirement specifications and ensure clear traceability to system specifications, design artifacts, and test deliverables
Perform requirements decomposition, verification, validation, and troubleshooting – Break down high‑level requirements into implementable units, verify and validate each element throughout the development cycle, and resolve issues through systematic analysis
Implement software solutions – Write clean, maintainable, and testable code in C, C++, Java, LabVIEW, Python, or other required languages; integrate modules, adhere to coding standards and security best practices, and modify code as needed for functional testing
Plan and execute software testing – Update and calibrate test equipment and fixtures. Develop comprehensive test cases and automated test suites. Conduct functional, integration, regression, and hardware‑in‑the‑loop testing. Perform hands‑on debugging, root‑cause analysis, and corrective actions. Oversee contractor testing activities when applicable to ensure compliance with test plans and quality criteria
Verify and validate requirements – Execute systematic V&V activities, confirm that the implemented software satisfies all stipulated requirements, and produce traceability matrices, verification reports, and compliance documentation
Produce comprehensive documentation – Author design‑review packages (PDR/CDR), verification & validation (V&V) reports, interface control documents (ICDs), user manuals, and detailed test procedures that support the full product lifecycle
Develop and apply control algorithms – Design closed‑loop control solutions (e.g., PID), state‑machine patterns, and motor‑control techniques for safety‑critical embedded systems
Collaborate with cross‑functional teams – Work closely with product‑development teammates, mechanical and electrical engineers, and other specialists to ensure seamless integration across the hardware‑software development process
Maintain configuration management – Use Git (or equivalent) for source‑code control, manage software builds, and ensure version‑controlled artifacts are available to the team
