We're looking for a AI-first Full Stack Engineer with a strong backend and Elixir expertise to own partner APIs and dashboards that power the qiibee ecosystem (partnered Miles & More, Etihad Guest, and more). In this role, you'll combine deep backend expertise with AI-powered workflows to take features through every stage — from architecture and coding to deployment, monitoring and ongoing improvement — across a double-entry ledger, partner-facing APIs and the React interfaces on top of them. You'll be a key point of ownership for our core platform, ensuring every partner integration is correct, reliable and well documented — supported by AI at every step. Tasks - Design, build and operate Elixir services with Phoenix, Ecto and OTP: APIs, workers and background jobs. - Build and evolve our partner-facing REST APIs, including versioning, outbound webhooks and delivery guarantees. - Work on money-adjacent systems where correctness comes first: ledgers, points balances, settlement and reconciliation. - Own frontend features end to end in React and TypeScript, from the admin and partner dashboards to the API behind them. - Use AI coding agents (Claude Code) daily to move faster, while reviewing their output. - Review code substantively, and act as a second pair of eyes on system correctness. - Write the reasoning down: clear PR descriptions, architecture notes, and docs updated in the same pull request as the code. - Collaborate with product and our infrastructure team on deployment, monitoring and security on AWS. Requirements - AI first: Use AI coding tools (Claude Code, Cursor or similar) every day. - 6+ years of professional software engineering, with 4+ years on the backend. - 3+ years of production Elixir with Phoenix, Ecto and OTP, shipped and operated, not learned on the side. - Strong PostgreSQL: real SQL, transaction semantics and performance tuning. - Solid REST API design and background job processing (Oban or equivalent) with retries. - Proven experience in the loyalty, travel tech, payments or FinTech industries. - 2+ years of React and TypeScript, strong enough to own a frontend feature outright: components, state, forms, validation and error handling. - Working knowledge of AWS (ECS, RDS, S3), Docker and CI/CD with GitHub Actions. - Fluent in English Nice to have 🎯 - Built features on top of LLM APIs or AI agent workflows - Redux Toolkit / RTK Query, LiveView, Node.js (Express) or GraphQL. - Multi-tenant B2B platforms, multi-region architectures, observability (AppSignal, Sentry, Datadog) and SOC 2 exposure. Benefits 🚀 Benefits: - Fully remote work - Competitive monthly salary package - Equity share and qiibee tokens (QBX), sharing in our success - Fast-paced remote startup environment 💫 About us: At qiibee, we're on a mission to turn loyalty currencies into one of the world's largest payment methods. Our points exchange platform lets businesses and loyalty programs issue and redeem loyalty rewards instantly, unlocking real purchasing power and economic freedom for their members. We're an AI-first, international team, building an increasingly agentic company where AI handles the busywork so our people can focus on what matters most: our customers. We're looking for ambitious, high-performing people who are eager for growth, challenges, and continuous learning to help us turn our vision into reality.
