About The Position

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.

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

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
