Founding Engineer (Full-Stack) (Remote)

Salary: AED 3,000 - 6,500

We are looking for a Founding Engineer to join Lexilio — an AI-powered contract review platform built for construction teams. We use Next.js, TypeScript, Supabase, and multi LLM models.

This is a founding team role with real ownership. You will ship features that construction teams use daily, not push tickets through a queue.

Tasks:

Build and own core product features end-to-end — frontend, backend, database, AI integration

Implement Stripe billing, export reports (PDF/Word), and AWS Textract for scanned document processing

Improve the multi-model AI router — prompt engineering, caching, cost optimisation

Build integrations (Procore API, Microsoft Word add-in) as the product matures

Write clean, tested, production-grade code that ships to real users

Collaborate directly with the founder on architecture decisions and technical direction

Requirements:

Strong experience with Next.js (App Router), TypeScript, and React

Experience with Supabase or PostgreSQL

Comfortable working with AI/LLM APIs (Anthropic, OpenAI) — you do not need ML expertise, but you should understand prompt engineering and token management

Ability to ship full features independently — you are not waiting for specs, you are building the spec

Comfortable in an early-stage environment where priorities shift and speed matters

Good instincts for UX — you care about what the user sees, not just what the code does

Nice to have:

Experience with Stripe integration, PDF processing, or document AI

Knowledge of construction industry or legal tech

Contributions to open source or shipped side projects

AWS experience (Textract, S3, IAM)

Experience with Vibe Coding

Compensation:

Significant founding equity

Competitive base (flexible — full-time or contract initially)

Remote-first, async-friendly

Our stack: Next.js 14 (App Router), TypeScript, Supabase (PostgreSQL + Auth + Storage), Anthropic Claude API, OpenAI API, Railway (deployment), Vercel (marketing site). We ship daily.
