Harness Engineering Intern

About us:

Playo is a leading global sports activity platform with over 5 million users across 5 countries, that connects players, venues, trainers, and brands in one full stack ecosystem across 50+ sports. We operate at the intersection of consumer technology, social networking, marketplaces & real-world logistics and are building a scalable, multi-vertical sports-tech venture with a focus on long-term sustainability and global dominance.

The Opportunity:

With coding agents now writing a meaningful share of the codebase, quality engineering means designing the system of guides and sensors that wraps every change contributing to Playo's stack. We're hiring a Harness Engineer Intern to help build this system.

Roles and Responsibilities:

• Build the behaviour harness for Playo's services — end-to-end and API test automation across our stack and AI-driven test generation.
• Build feedforward guides and feedback sensors that catch regressions early and self-correct.

Requirements:

• Strong programming fundamentals in TypeScript/JavaScript or Python
• Working understanding of REST/GraphQL APIs, microservices, Docker and Github Actions
• Hands-on exposure to at least one E2E framework (Playwright, Cypress, or Selenium) or API testing tool (Postman/Newman, REST Assured, Supertest) via projects / internships
• Demonstrated use of AI coding assistants (Claude Code, Cursor, Copilot) on real projects — bonus if you've authored AGENTS.md/CLAUDE.md files, written custom Skills, or built/used MCP servers
• Passion for sports and fitness
• Excitement about working in a fast-paced startup environment
