We’re looking for a Full-Stack Software Engineer who can own features end-to-end, from database schema design through production deployment.

You’ll work across our entire stack to build customer-facing products and internal tools, with significant autonomy and direct impact on the business.

What You’ll Do

  • Design and implement full-stack features using modern TypeScript across the frontend and backend
  • Architect, build, and maintain robust RESTful APIs with proper authentication, validation, and error handling
  • Maintain high engineering standards through comprehensive testing, including unit, integration, and end-to-end tests
  • Containerize and deploy services using Docker and CI/CD pipelines
  • Collaborate closely with the founding team on product direction, architecture, and technical strategy
  • Contribute to scalable, maintainable system architecture in a fast-moving startup environment

Requirements

  • 2+ years of experience
  • Strong proficiency with TypeScript and Node.js
  • Experience building production-grade frontends with React; Next.js preferred
  • Familiarity with modern frontend tooling, such as Tailwind and component libraries
  • Backend development experience with frameworks like Fastify or similar
  • Solid understanding of PostgreSQL, including schema design and query performance
  • Familiarity with Docker, CI/CD workflows, and cloud deployment environments
  • Experience implementing secure authentication flows, such as JWT or OAuth
  • Strong testing discipline — you write tests as part of building features, not after the fact

Nice to Have

  • Experience with type-safe ORMs such as Kysely, Drizzle, or similar
  • Knowledge of Redis for caching and performance optimization
  • Comfort with Nginx configuration, reverse proxies, and SSL/TLS setup
  • Experience with monorepo tooling such as Turborepo or Nx
  • Prior work on SaaS platforms or multi-tenant architectures
