Software Development Engineer in Test (SDET)

Accountabilities

• Collaborate with software development and quality assurance teams to understand product requirements and translate them into comprehensive test plans.

• Design, develop, and execute automated API and service-level tests for .NET backend services, including contract testing and mocking downstream dependencies.

• Validate end-to-end workflows across application layers, ensuring that user interface actions trigger the correct backend processes, data is accurately stored in SQL Server, and results are correctly displayed.

• Test asynchronous, event-driven, and batch processes on AWS, including Lambda, SQS/SNS, and scheduled jobs, with particular attention to retries, failure handling, and idempotency.

• Develop and maintain automated and manual test cases for SaaS web applications using modern JavaScript-based automation tools.

• Build, maintain, and continuously improve the test automation framework, defining standards and best practices across the engineering team.

• Create and maintain test data strategies using synthetic data, ensuring protected health information (PHI) is only used within approved environments.

• Use SQL queries to validate data integrity, transformations, and application state changes in SQL Server.

• Analyze application logs and monitoring data, including AWS CloudWatch, to diagnose failures and verify backend behavior.

• Conduct API and backend performance, load, and stress testing using tools such as k6, JMeter, or NBomber, establishing baselines and identifying regressions.

• Integrate automated testing into continuous integration and continuous delivery workflows.

• Own the test automation strategy and roadmap, determining testing priorities and identifying opportunities to improve coverage and efficiency.

• Apply AI-assisted failure analysis to identify root causes such as flaky network calls, timing issues, and data-state problems, reducing manual troubleshooting.

• Leverage AI-driven test case generation and coverage analysis to identify edge cases, uncover untested code paths, and strengthen testing of regulatory and compliance workflows.

• Partner with product and engineering leadership to identify testing gaps and compliance risks, particularly those involving HIPAA and PHI handling.

• Mentor junior automation engineers, conduct code reviews, and lead cross-functional initiatives that improve testing velocity and shorten release cycles.

• Stay current with testing technologies and methodologies, recommending improvements to tools, processes, and engineering practices.

Requirements:

• Bachelor's degree in Computer Science or a related field, or equivalent practical experience.

• At least 5 years of software development experience, with a focus on testing and test automation for SaaS web applications and backend services.

• Strong programming skills in C# and JavaScript or TypeScript.

• Experience with .NET testing frameworks such as NUnit, xUnit, or MSTest.

• Hands-on experience with modern end-to-end automation tools such as Cypress, CodeceptJS, or Playwright.

• Familiarity with API testing tools and frameworks, including Postman, RestSharp, or Pact for contract testing.

• Strong SQL skills and practical experience validating data in Microsoft SQL Server.

• Experience testing AWS services and workflows, including Lambda, SQS/SNS, S3, and CloudWatch.

• Understanding of asynchronous, event-driven, and batch-processing architectures.

• Experience with Agile development methodologies and continuous integration and delivery practices.

• Knowledge of performance testing tools such as k6, JMeter, or NBomber.

• Strong analytical and problem-solving abilities, with exceptional attention to detail.

• Excellent communication and collaboration skills, with the ability to build effective partnerships across technical and business teams.

• A proactive, self-motivated approach and the ability to deliver results in a fast-paced environment.

• Healthcare industry experience is highly preferred, particularly familiarity with HIPAA requirements and handling protected health information.

• Experience mentoring engineers, reviewing automation code, and defining testing standards is valuable for success in this role.

• Must be eligible to work in the United States; new hires are subject to employment eligibility verification.

Benefits:

• Annual salary: $135,000–$160,000, with compensation determined by geographic labor market, relevant knowledge, skills, and experience.

• Medical, dental, and vision insurance.

• 401(k) retirement plan with employer matching contributions.

• Generous paid time off (PTO).
