Summary

Job Description

The Software Development Engineer in Test (SDET) will be responsible for developing automated tests to ensure the quality of software systems and applications. The role involves creating test plans, writing code for automating tests, maintaining existing tests, and reporting on product defects. The SDET will work closely with developers, test engineers and other stakeholders to identify issues early in development cycles and provide feedback to improve overall system reliability. This position requires strong technical skills as well as excellent communication abilities.

We are looking for a Software Developer in Test to own and develop our automated test platform. This is a software engineering role first, you will design and build production-quality code that verifies software, not a testing role that occasionally writes scripts. You will architect test infrastructure and contribute to shared libraries.

Responsibilities

• Design, build, and maintain a multi-module test infrastructure spanning API, browser, performance, and protocol-level testing disciplines
• Create and maintain automated functional, integration, system, regression and performance tests.
• Develop and version reusable shared libraries, authentication clients, model libraries, and data providers consumed across multiple test modules
• Build software tests that interface with external systems and hardware devices to enable isolated, reproducible test environments independent of third-party availability
• Engineer layered API client abstractions that handle authentication, request construction, response validation, and structured logging
• Design and execute tests that model realistic concurrent user journeys and produce actionable results
• Author and maintain CI/CD pipeline definitions that execute, gate, and report on test results across environments and deployment targets
• Integrate test execution with external test management and defect tracking systems to maintain traceability from requirement to result
• Enforce production-grade engineering standards on test code, design patterns, code review, refactoring, and module-level abstractions
• Collaborate on API contracts, authentication flows, and system observability from a testability perspective during design and development

Minimum Required

• Bachelor’s in Computer Science, Engineering or related discipline.
• 3+ years of professional software development, test automation or quality engineering experience
• Fluent in C#; able to design and build maintainable, extensible code at module and library level
• Proven experience building test frameworks and shared libraries from scratch.
• Proficiency with multi-module build systems, dependency management, and library versioning at scale
• Experience authoring and owning CI/CD pipeline definitions end-to-end, including containerized test environments
• Familiarity with structured test reporting, code coverage analysis, and static quality tooling
• Experience with Defect Tracking Tools, Requirements Management and Test Management Tools such as ADO, Cognition Cockpit, and JAMA software
• Experience with Agile and Scrum methodologies in software development
• Excellent interpersonal skills, decision-making, and problem-solving skills
• Effective written and verbal communications skills, ability to clearly and precisely communicate with management and remote team members
• Familiarity with FDA regulations for medical instruments, ISO 13485, IEC 62304 standards and Quality Management systems

Preferred Skills

• Master’s degree in Computer Science, Engineering or related discipline
• Experience building software simulators for external systems, APIs, or hardware devices
