About the Role

We are looking for a Full Stack Engineer (Next.js + tRPC) to work closely with the founding team in building and scaling a modern, high-performance web platform. You'll play a key role in shaping both the product and engineering decisions, collaborating across product, engineering, and marketing to deliver a seamless user experience. This is a role for someone who is comfortable working in a fast-paced startup environment, taking ownership, and contributing across the stack, from frontend UX to backend APIs and integrations.

Key Responsibilities

• Build and maintain scalable web applications using Next.js (App Router) and React 18
• Develop end-to-end type-safe APIs using tRPC and backend services with Hono
• Design and manage database schemas and queries using PostgreSQL and Prisma
• Collaborate directly with co-founders to define product requirements, architecture, and roadmap
• Work closely with the marketing team to implement SEO strategies and optimize web performance
• Integrate third-party services like Clerk (authentication) and Stripe (payments)
• Implement responsive and accessible UI using Tailwind CSS, Shadcn, Radix UI, and modern component patterns
• Manage server state and data fetching using TanStack React Query
• Contribute to analytics, logging, and monitoring using tools like PostHog and Axiom
• Participate in code reviews, architectural discussions, and performance optimizations
• Work within a monorepo setup (pnpm + Turborepo) for efficient development and scaling

Must-Have Qualifications

• Proficiency in TypeScript
• Hands-on experience with Next.js and React
• Experience building APIs using tRPC or similar frameworks
• Solid understanding of backend development (Node.js-based frameworks like Hono or Express)
• Experience with PostgreSQL and ORMs like Prisma
• Strong knowledge of REST/HTTP concepts, API design, and data fetching strategies
• React Query (TanStack Query) for server state management
• Experience with modern styling approaches like Tailwind CSS
• Familiarity with Git and collaborative workflows
• Strong problem-solving skills, attention to detail, and ability to take ownership of features from concept to production

Nice-to-Have Skills

• Experience with monorepo setups using Turborepo and pnpm
• Familiarity with authentication systems like Clerk
• Experience with Stripe or payment integrations
• Experience with AI integrations (e.g., OpenAI, Vercel AI SDK)
• Exposure to Docker and cloud services like AWS S3
• Experience working on SEO optimization and performance improvements
• Prior experience working closely with founders or startup teams

What Success Looks Like

• Owning and shipping features end-to-end with minimal hand-holding
• Writing clean, scalable, and well-documented code that the team can build on
• Proactively identifying performance bottlenecks and resolving them before they become problems
• Contributing meaningfully to architectural and product decisions alongside the founding team

What's in It for You

• Work directly with the founding team, fast learning and real ownership from Day 1
• Shape the product and engineering culture at an early-stage, fast-growing startup
• Work on a modern, cutting-edge tech stack across the full product lifecycle
