Software Development Engineer in Test (SDET)

Sharetec Systems is a company dedicated to developing innovative core banking and lending software solutions for credit unions. They are seeking a Software Development Engineer in Test (SDET) to build and own the test automation infrastructure, design automation frameworks, and integrate them into CI/CD pipelines to ensure quality software delivery.

Responsibilities:

• Design, build, and maintain scalable automated test frameworks from scratch — not inherited or extended from existing suites
• Serve as the primary subject matter expert on test automation tools, techniques, and best practices across the engineering organization
• Establish architecture, folder structure, conventions, and shared patterns for the automation codebase
• Maintain test suites for reliability and maintainability as the platform evolves
• Integrate automated test suites into CI/CD pipelines (GitHub Actions, Azure DevOps, or equivalent) to support continuous delivery
• Design pipeline triggers, handle test parallelism and flakiness, and own reporting and alerting within the pipeline
• Identify gaps in current testing infrastructure and proactively propose and implement improvements
• Partner with DevOps and Engineering to ensure test execution environments are reliable and representative
• Partner with product managers and developers to integrate automation early in the SDLC, promoting a shift-left quality mindset
• Influence team QA practices through documentation, mentorship, and standards-setting — not just personal execution
• Review pull requests for testability and advocate for design choices that improve coverage and maintainability
• Stay current on emerging testing tools, frameworks, and industry trends
• Evaluate and advocate for adoption of new tools and approaches where they improve quality outcomes

Requirements:

• 5+ years of professional software testing or SDET experience
• Demonstrable experience building test automation frameworks from scratch — not just using or maintaining inherited ones
• Hands-on Playwright experience in a production-grade project
• Python proficiency demonstrated through professional or open-source work
• API testing ownership using Postman or equivalent — including contract testing, data-driven tests, and CI integration
• CI/CD pipeline ownership — built or significantly extended a pipeline using GitHub Actions, Azure DevOps, Jenkins, or equivalent
• Experience testing .NET / C# applications in a production environment
• Experience with long-lived production platforms — not just greenfield or short-term contract work
• Experience in fintech, financial services, or SaaS B2B software
• Familiarity with performance or load testing tools such as JMeter or k6
• Experience with cloud-based or containerized test execution environments
• Exposure to security testing concepts and practices
• Early leadership signals — mentoring peers, defining QA standards, or influencing team practices
• Bachelor's degree in Computer Science, Software Engineering, or a related field (or equivalent hands-on experience)
