This is a hands-on engineering role at the intersection of software development, quality engineering, security testing, and AI enablement. You'll turn common testing challenges into reusable solutions, develop and evaluate AI-assisted testing capabilities, and integrate quality and security checks directly into engineering workflows. You'll collaborate across QA, Engineering, and Security to create solutions teams can trust and adopt at scale. Just as importantly, you'll help shape shared testing practices, mentor others, and measure how our tools improve coverage, reduce manual effort, and accelerate feedback. Your Day-to-Day * Design, build, test, and maintain shared automation frameworks, internal services, and developer tools that serve multiple QA and engineering teams. * Partner with QA and engineering teams to identify common testing needs and validate functionality, integration, reliability, performance, and usability across application and platform layers. * Build and evaluate AI-assisted and agent-based testing capabilities using repeatable evaluations, human oversight, appropriate tool permissions, and fallback behavior for unreliable results. * Develop and automate security testing for APIs, applications, and shared platforms, including authentication, authorization, access boundaries, and sensitive-data handling; partner with Security teams to validate findings and verify fixes. * Test AI-enabled tooling for incorrect outputs, prompt injection, information exposure, unintended actions, and behavior when inputs or dependent services fail. * Integrate reusable quality and security checks into CI/CD workflows, supported by actionable diagnostics, maintainable test data, clear documentation, and compatibility across supported environments. * Investigate failures and production issues in shared tools and platforms, using targeted experiments and operational feedback to assess correctness, reliability, maintenance effort, and cost. * Drive adoption through documentation, demonstrations, and mentoring while establishing shared testing practices and measuring improvements in test coverage, manual effort, and feedback time. ## Related Videos - [How I Built QA from Scratch in a Scaling Startup - no fluff real life story](https://www.wearedevelopers.com/videos/2041-how-i-built-qa-from-scratch-in-a-scaling-startup-no-fluff-real-life-story) - [Are Code Reviews Worth It?
