About SweatPals

SweatPals is the community-first fitness platform that turns workouts into social adventures. Backed by a16z speedrun, Patron, Kevin Hart, and other world-class investors such as founders of Instacart and Dreamworks Animations, we connect hundreds of thousands of “Pals,” hosts, and gyms through events, memberships, and rich social features. We’re still scrappy at heart, but we’re scaling fast—and personalized, intelligent experiences are central to our next chapter.

• Design and document APIs (REST and GraphQL) consumed by web and mobile clients

• Build scalable systems with PostgreSQL and cloud-native patterns (AWS / GCP)

• Improve developer experience and system reliability through better tooling, observability, and CI/CD

• Collaborate closely with product, design, and community teams to deliver features that power growth and engagement

• Strong TypeScript skills across both frontend and backend

• Solid understanding of PostgreSQL, including performance tuning and indexing

• Comfort with cloud environments (AWS, GCP, or Azure) – provisioning, permissions, automation

• Familiarity with CI/CD workflows and tooling

• Experience owning and shipping features end-to-end in a startup or fast-moving environment

• Clear, collaborative communication style

Bonus Points

• Experience with monorepos (e.g., Turborepo, Nx)
