Senior Software Development Engineer In Test

MiniMed•Northridge, CA

About The Position

The Senior Software Development Engineer in Test 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.

Requirements

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.
Strong hands-on programming proficiency in Python and JavaScript, including code design, debugging, refactoring, use of version control, and development of reusable functions and libraries.
Hands-on experience with embedded debugging and test tools such as HIL systems, simulators, test fixtures, serial interfaces, protocol analyzers, device logs, or laboratory instruments.
Demonstrated hands-on software development experience building and maintaining automated test frameworks, reusable libraries, and utilities; ability to debug and resolve issues in test code independently.
Experience integrating automated tests into CI/CD workflows, including pipeline configuration, test execution, quality gates, reporting, and diagnosis of pipeline failures.
Experience with AI-enabled testing or AI-assisted engineering workflows, including the ability to evaluate output quality, maintain appropriate traceability and human review, and apply generated code responsibly.
Working knowledge of verification and validation, requirements traceability, risk-based testing, defect investigation, and root-cause analysis in a regulated environment.
Strong written and verbal communication, analytical problem-solving, and collaboration skills.

Nice To Haves

Bachelor's degree in Computer Science, Software Engineering, Electrical Engineering, Biomedical Engineering, or a related technical discipline.
Experience testing embedded software, firmware, real-time systems, or hardware/software integrated products; medical-device experience is strongly preferred.
Experience with device communication protocols, wireless connectivity, or embedded interfaces is preferred.
Experience with Appium is a plus for occasional companion-application or system-workflow automation; it is not a primary responsibility of this embedded pump-testing role.
Experience with Arduino and/or Raspberry Pi boards for embedded test.

Responsibilities

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.
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.
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.
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.
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.
