Job Description

Contract duration: 6 months (with a potential extension)
Engagement Type: Full-time
Start date: July 2026
Location: Abu Dhabi (on-site)

We are seeking an experienced Full-Stack Engineer to own features from database to interface — designing APIs and data models, building responsive frontends, and shipping production code with tests, observability, and CI/CD. We value breadth across the stack with enough depth to make sound architectural calls.

The modern full-stack role increasingly includes integrating AI: calling LLM APIs, building RAG-backed and agentic features, and streaming model output into the UI. We work TypeScript-first, edge-aware, and type-safe end-to-end, with AI coding assistants as part of the everyday toolchain.


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.

Tools & Technologies You’ll Work With:

  • Frontend: React, Next.js (App Router, RSC), Vue/Nuxt, Svelte/SvelteKit, Tailwind CSS, shadcn/ui.

  • State & data: TanStack Query, Zustand, Server Actions.

  • Backend: Node.js, Bun; FastAPI/Django, Spring Boot, .NET, Go.

  • APIs & data: REST, GraphQL, tRPC, gRPC; PostgreSQL, MongoDB, Redis, pgvector; Prisma, Drizzle.

  • AI integration: Vercel AI SDK, OpenAI/Anthropic/Gemini SDKs, RAG and embeddings.

  • Auth & testing: OAuth/OIDC, Auth.js, Clerk; Vitest, Jest, Playwright, Cypress.

  • Build & deploy: Vite, Turborepo/Nx, pnpm; Vercel, AWS/Azure/GCP, Docker, GitHub Actions; Sentry.
