Product Engineering & Delivery

• Build real, production-grade features end-to-end, working across the full stack using Next.js, React 19, Node.js, and PostgreSQL, owning everything from polished UI components to scalable APIs and data models
• Ship fast using modern, AI-augmented development workflows with tools like Cursor and Claude Code to prototype ideas, generate code, refactor safely, and learn new patterns
• Write automated tests with Playwright and Jest to ensure quality and confidence in every release
• Design and ship well-structured Fastify-based APIs with OpenAPI documentation, type-safe validation, and clear contracts between frontend and backend systems
• Integrate real-world services including Clerk for authentication, AWS S3 for storage, SendGrid and Twilio for communications, and Google Maps for location-based features
• Ship to web and mobile by deploying PWAs and mobile apps using Capacitor and PWABuilder
• Contribute to CI/CD pipelines using GitHub Actions and help optimize performance and reliability
  

AI-Assisted Development & Collaboration

• Use AI tools pragmatically; understand when to leverage Claude Code/Cursor for speed vs. when to hand-craft solutions
• Review AI-generated code critically, ensuring security, performance, and maintainability standards
• Define best practices for AI-assisted development within our codebase
• Debug across the stack; troubleshoot issues in React components, API endpoints, database queries, and native mobile apps
• Communicate trade-offs clearly, balancing speed, quality, and technical debt in fast-moving environments

Tools You'll Use

• Next.js, React 19, TypeScript (frontend)
• Node.js, Fastify (backend)
• PostgreSQL (database)
• Claude Code, Cursor (AI-assisted development)
• Playwright, Jest (testing)
• GitHub Actions (CI/CD)
• Capacitor, PWABuilder (mobile)
• Clerk, AWS S3, SendGrid, Twilio, Google Maps (integrations)
• ClickUp (team communication and task management)

You'll be onboarded to the tech team organization. You will be part of a team and will communicate with them via Slack and Google Meet. Periodic 1-on-1 meetings will be held to ensure you are successful and have a productive and enjoyable experience.

• Excited to be part of a small, fast-moving digital-native team where your input directly shapes how things work
• Advanced English level.
  
  

AI is part of the core workflow, every day, for real work. This is not a traditional full-stack role where AI is a nice-to-have.

This role is for developers who:

• Think in terms of “prompt → generate → validate → refine → ship”
• Are comfortable letting AI write the first version of most things.
• Take responsibility for the correctness, security, performance, and maintainability of AI-assisted output.
• See AI as a force multiplier, not a threat to craftsmanship
  

• Experience with Next.js (App Router) and Node.js / Fastify.
• Background in end-to-end testing (Playwright, Cypress, or similar).
• Experience with mobile or PWA development.
• Familiarity with modern frontend tooling and state management.
• Experience integrating cloud services and third-party APIs.
• Exposure to monitoring or analytics tools.
• Experience in B2C platforms, sports-tech, or consumer-facing products.
