Support technical interviews, evaluate development tools, analyze software metrics, and apply sound judgment to improve delivery.

Bachelor's degree in Computer Science, Software Engineering, Computer Engineering, Electrical Engineering, Biomedical Engineering, or a related discipline; equivalent experience may be considered.

Typically 6+ years of professional software-development experience, including substantial hands-on C#/.NET development; regulated medical-device, safety-critical, or IoT experience is strongly preferred.

Strong experience with object-oriented design, application architecture, design patterns, dependency management, and maintainable software practices.

Experience developing and executing unit, functional, and integration tests, including mocks/test doubles, code coverage, static analysis, CI/CD, and configuration management.

Experience with database-backed applications and database design or implementation decisions.

Experience designing, implementing, and consuming APIs or interprocess communication interfaces; RESTful API experience is preferred.

Experience integrating software with firmware, sensors, electromechanical systems, embedded Linux, or hardware-controlled products is preferred;
Yocto familiarity is a plus.

Python proficiency for automation, testing, data processing, or development-support scripts is preferred.

Experience with Jira, Git, distributed development teams, and external development partners.

Ability to work with ambiguous requirements, ask precise clarification questions, identify downstream impacts, and communicate technical concepts clearly to non-software stakeholders.

Knowledge of software-development documentation and design-control expectations for medical devices or other regulated products is preferred.

Demonstrated ownership, problem-solving ability, individual leadership, and interest in mentoring other developers.

Supervisory Responsibilities No formal direct report responsibilities initially. The position is expected to provide increasing technical leadership, mentoring, design oversight,…
