Software EngineerSoftware Engineering

The SDET will play a key role in strengthening software quality, reliability, and performance across a healthcare-focused SaaS platform. This position combines hands-on test automation engineering with ownership of the broader testing strategy and roadmap. You will design and maintain automated testing solutions for .NET backend services, APIs, web applications, and cloud-based workflows. Working closely with engineering, product, and quality teams, you will help ensure data integrity, regulatory compliance, and dependable user experiences. You will also introduce AI-assisted testing practices and performance monitoring to improve coverage and accelerate release cycles. This is an opportunity to influence engineering standards while mentoring other automation professionals in a collaborative, fast-paced environment.

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.
