Overview

Full-Time

Role Overview

Key Responsibilities

• Build responsive, accessible interfaces with React/Next.js (or Vue/Svelte) and TypeScript.
• Develop and maintain backend services and APIs (REST, GraphQL, gRPC, or tRPC) with clean domain models.
• Design relational and non-relational data models, write performant queries, and manage migrations.
• Integrate AI features — call LLM APIs, build RAG and tool-using flows, and stream output into the UI.
• Implement authentication and authorization securely (OAuth/OIDC, JWT, managed auth providers).
• Write automated tests across the stack — unit, integration, and end-to-end.
• Own features end-to-end, from design through deployment, monitoring, and iteration.
• Optimize performance: rendering strategy (SSR/SSG/ISR/edge), caching, Core Web Vitals, and query tuning.

Candidate Requirements

• Demonstrated experience delivering AI solutions in an enterprise or client-facing/consulting environment.
• Prior experience at management consulting firms and/or Big Tech is an advantage.
• Bachelor's or Master’s degree in Computer Science, Engineering, Information Technology, or a related field.
• 3+ years building and shipping production web apps across frontend and backend.
• Strong JavaScript/TypeScript and a modern frontend framework (React/Next.js, Vue, or Svelte).
• Backend experience in at least one of Node.js, Python, Go, Java, or .NET, with solid API design.
• Strong SQL and database design (PostgreSQL/MySQL) plus a NoSQL or caching store.
• Experience with Git, CI/CD, testing, and deploying to a cloud or serverless platform.
• A solid understanding of web fundamentals: HTTP, REST, auth, caching, security, and performance.
• Experience integrating third-party and/or AI APIs into applications.

Nice To Have

• AI-native product features (copilots, RAG search, agentic flows).
• Monorepo tooling and design systems.
• Real-time features (WebSockets, CRDTs, collaborative editing).
• Mobile or cross-platform experience (React Native, Expo).
• DevOps fluency — containers, IaC basics, owning your own deployments.
