Playbypoint
Senior Full Stack Software Engineer — Developer Platform (Remote LATAM)
About this role
Company: Playbypoint Team: Core Platform Location:LATAM remote. Open to other timezones with overlap to UTC-3 / UTC-5. Employment: Full-time Reports to: Engineering Manager, Core Platform About Playbypoint We're a rapidly expanding startup at the forefront of the racquet sports industry. At Playbypoint, we specialize in providing innovative enterprise software solutions that empower clubs, players, and coaches to streamline their operations and enhance their game. We're backed by top investors, trusted by leading clubs, and scaling fast – and we're looking for passionate individuals to join us in revolutionizing the racquet sports world with cutting-edge software. The Role We're building the platform that lets the world build on top of Playbypoint — and we're looking for a Senior Full Stack Engineer to be part of it. This goes beyond a traditional external API: you'll design and deliver the full stack of surfaces that enable developers, partners, and AI agents to integrate with us — REST APIs, MCP servers, skills, webhooks, and the developer experience layer that ties it all together. This is a high-visibility, high-ownership role at the intersection of platform engineering and the emerging ecosystem of AI-powered builders. Our stack: Ruby on Rails (backend), React + TypeScript (frontend), GraphQL and REST APIs, MySQL / Redis / Sidekiq, cloud-native infrastructure on AWS.
What You'll Do
- Design and build Playbypoint's external API — versioned, stable, and built to scale with a growing ecosystem of integrators and partners.
- Develop and maintain MCP servers and skills that expose Playbypoint capabilities to AI agents and developer tools.
- Own the developer experience end to end: API documentation, developer portal, onboarding flows, SDKs, and sandbox environments.
- Define API governance practices: versioning strategy, deprecation policies, backward compatibility, and breaking change management.
- Build the infrastructure that makes our external surfaces observable and reliable — rate limiting, auth, throttling, usage analytics.
- Partner with product and internal engineering teams to expose platform capabilities through well-designed, consistent integration contracts.
- Track and shape how the ecosystem of builders — human and AI — integrates with Playbypoint. You Might Thrive in This Role If You
- Have 7+ years of software engineering experience, with significant focus on API design, platform development, or developer tooling.
- Are comfortable across the full stack — backend API design and frontend developer portal/documentation surfaces.
- Have designed and shipped public or partner-facing APIs at scale — versioning, auth models, rate limiting, and the full lifecycle of an external API are familiar territory.
- Have hands-on experience building for AI-era integration surfaces — MCP servers, agent skills, LLM tool definitions, or similar patterns.
