Full Stack Engineer (Elixir Backend Focus)

Were 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 youll 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.

Youll 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.

• 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.

• 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.
• 3 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 (Express) or GraphQL.
• Multi-tenant B2B platforms multi-region architectures observability (AppSignal Sentry Datadog) and SOC 2 exposure.

Benefits:

• Fully remote work
• Competitive monthly salary package
• Equity share and qiibee tokens (QBX) sharing in our success
• Fast-paced remote startup environment
