About the Role

The Senior Software Development Engineer in Test - Embedded Software/Firmware is a coding-focused individual contributor responsible for verification and validation (V&V) of embedded software used in insulin-pump systems. This role develops and maintains automated test software, reusable libraries, frameworks, and CI/CD integrations while executing risk-based testing across firmware, embedded applications, device interfaces, hardware/software integration, and supporting test infrastructure. The engineer partners closely with software, systems, hardware, quality, and regulatory teams to build high-confidence evidence that product requirements are met and patient safety is protected.

Responsibilities may include the following and other duties may be assigned.

Embedded Test Automation & Engineering Tools

• Design, develop, version, and maintain production-quality automated test scripts, test library functions, framework APIs, utilities, and test data using Python and JavaScript.
• Write clean, maintainable, and well-structured test software for embedded-device workflows including device configuration, communication interfaces, logging, data capture, and result analysis.
• Integrate, troubleshoot, and maintain automated tests in source control and CI/CD pipelines, including test execution, quality gates, reporting, and failure diagnostics.
• Debug test scripts, framework libraries, CI/CD failures, and test-environment issues; identify root causes and implement durable corrective fixes.

Embedded Pump Software Verification & Validation

• Develop and execute test strategies, test plans, protocols, test cases, and reports for embedded pump firmware.
• Analyze software and system requirements, architecture, interfaces, and risk controls to identify test conditions, gaps, and traceable verification evidence.
• Perform functional, integration, regression, reliability, fault-injection, and recovery testing of embedded device behavior.
• Validate hardware/software interactions using hardware-in-the-loop (HIL) and software-in-the-loop (SIL) benches, simulators, test fixtures, and laboratory equipment.
• Investigate defects, isolate root causes, document reproducible evidence, and partner with development teams through resolution and verification.

AI-Enabled Quality Engineering

• Apply AI-assisted tools responsibly to improve requirements analysis, test design, test-data generation, log analysis, defect triage, and test documentation.
• Evaluate AI-enabled testing capabilities for accuracy, traceability, security, intended use, and fit within a regulated medical-device development environment.
• Use engineering judgment to review AI-generated outputs and ensure that test evidence remains accurate, reproducible, and compliant with established quality processes.

Quality, Risk & Regulatory Compliance

• Create and maintain objective V&V evidence, including traceability between requirements, risks, tests, results, deviations, and defects.
• Execute risk-based testing in accordance with design controls, applicable procedures, and relevant medical-device standards, including IEC 62304, ISO 13485, and risk-management processes.
• Support design reviews, risk analyses, audits, investigations, CAPAs, and release-readiness activities as needed.
• Identify quality risks and opportunities to improve test coverage, product reliability, and engineering processes.

Cross-Functional Collaboration & Technical Leadership

• Collaborate with Systems Engineering, Embedded Software, Hardware, Quality, Regulatory, Cybersecurity, and Manufacturing teams throughout the product lifecycle.
• Communicate test status, quality risks, defects, and recommendations clearly to technical and cross-functional stakeholders.
• Provide technical guidance and mentorship to test engineers, share automation and embedded-test practices, and contribute as a senior member of the team.

Required Qualifications

Requires a bachelor's degree and minimum of 4 years of relevant experience, or an advanced degree with a minimum of 2 years of relevant experience.

Preferred Qualifications

• Bachelor's degree in Computer Science, Software Engineering, Electrical Engineering, Biomedical Engineering, or a related technical discipline.
• Experience testing safety-critical embedded products, particularly medical devices or insulin-delivery systems, and firmware operating under real-time constraints.
• Experience using both Python and JavaScript for embedded test automation, and familiarity with reading C or C++ firmware to support test design and defect investigation.
• Experience designing, extending, or maintaining HIL/SIL environments, device simulator
