Senior Software Developer in Test (SDET)

Responsibilities:

• Design, build, and maintain a multi-module test infrastructure spanning API, browser, performance, and protocol-level testing disciplines.
• Develop and version reusable shared libraries, authentication clients, model libraries, device simulators, and data providers consumed across multiple test modules.
• Build software simulators for 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 load simulations that model realistic concurrent user journeys, define SLO thresholds, 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
• Advise on API contracts, authentication flows, and system observability from a testability perspective during design and development
• Mentor engineers contributing to the test codebase and establish conventions that allow the platform to scale with the team
• Minimum Required:
• Bachelor's degree, preferably in Software engineering/Computer science
• 3+ years of professional software development experience with a strong foundation in object-oriented design and clean code principles.
• Proficiency in Java; able to design and build maintainable, extensible code at module and library level
• Proven experience building test frameworks and shared libraries from scratch (not just writing tests within an existing one)
• Deep understanding of OAuth 2.0 authentication flows including client credentials, PKCE, bearer token injection, and thread-safe token refresh.
• Hands-on experience engineering browser automation frameworks including page object hierarchies, dynamic wait strategies, and failure diagnostics
• Experience designing and executing load simulations with realistic user journey modeling and JVM tuning for high-concurrency execution
• 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
• Preferred skills and knowledge:
• Experience building software simulators for external systems, APIs, or hardware devices communicating over non-HTTP protocols (WebSocket, MQTT, TCP, or similar)
• Familiarity with healthcare messaging standards such as HL7 v2.x or FHIR
• Experience integrating test results with test management or defect tracking platforms (e.g. Xray, Zephyr)
• Background in domains involving regulated, safety-critical, or medical device software
• Contributions to open-source testing or developer tooling
