Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment. About the Role This project is suited for a Senior Python developer with deep functional testing experience, strong Linux and Docker skills, the ability to read code across multiple languages with the support of LLMs (e.g., C, Rust, Go) and translate requirements for migration tasks, and confidence using tools like Roo Code or Claude Code to accelerate iterative development. Key Responsibilities - Create functional black box tests for large codebases in various source languages - Create and manage Docker environments to ensure 100% reproducible builds and test execution across different platforms - Monitor code coverage and configure automated scoring criteria to meet industry benchmark-level standards - Leverage LLMs (Roo Code, Claude) to accelerate development cycles, automate repetitive tasks, and improve overall code quality

• Analyze product requirements and architect test plans • Contribute in team sprint planning meetings • Write, validate and execute test cases • Track defects and provide quality metrics • Collaborate with SDETs and other engineers on test strategies • Take ownership of and champion quality in areas of focus • Promote to the entire organization how important it is to ship high-quality / low-defect code

• Develop and execute test plans, test cases, and test scripts for software applications • Identify bugs and issues in the software and report them accurately • Work closely with development teams to understand software changes and ensure quality assurance • Participate in manual testing of software applications and coordinate automated testing efforts • Contribute to team meetings, reporting on testing progress and results • Continuously improve testing processes and methodologies

• Serve as the local expert and ultimate technical authority for your Pillar's test processes, feature interactions, and quality standards. • Engage early in the SDLC, contributing significantly to refinement, planning meetings, and RFC/Design reviews. Challenge Product Managers and Engineering Leads to consider testability, competitive edge, and integration risks before a single line of code is written. • Review and influence Pillar OKRs (e.g., engineering velocity, reliability) to identify partnership opportunities where QE tactics directly drive business objectives. • Take accountability for the quality of your Pillar by proactively identifying weak spots, automation blockers, and resource gaps, and aggressively escalating these to leadership to request support. • Represent your Pillar in the Cross-Module Leadership Team to coordinate cross-team impacts, share industry-leading practices, and align on standardized test plans and tooling across all pillars. • Architect and lead non-functional testing strategies across the pillar, explicitly championing performance, load, and scale testing to ensure the platform reliably handles enterprise-level concurrency and data volumes. • Drive AI Adoption & Standardization: Champion the use of AI in the testing lifecycle. Collaborate with the Internal Tools (Autobots) team to contribute to, adopt, and standardize common AI-based testing solutions across your pillar (e.g., leveraging AI for test script generation, intelligent failure triage, and pipeline optimization). • Champion the philosophy that quality is a shared engineering goal, ensuring development teams are equally accountable for automation maintenance and preventing the anti-pattern of "throwing it over the wall to QA." • Intelligently allocate QE efforts within your Pillar, prioritizing high-value user journeys and guiding your team to swarm on the most critical initiatives. • Contribute test code, audit Developer Unit/Integration tests for coverage gaps, and actively write complex End-to-End (E2E) automation scripts alongside your team. • Partner closely with your Pillar’s dedicated Automation Enablement engineer to ensure framework gaps are closed and flaky tests are managed urgently. • Act as a strong mentor and teacher of nuanced testing principles to both Feature QEs and Developers, empowering others to do the work while continuing to deliver impact yourself.
