Full-stack Software Engineer (x/f/m) - AI Developer Tools
The Engineering team
In our engineering team, we build the infrastructure, interfaces, and applications to provide first-class service to our members, health professionals, and even ourselves.
Being an engineer at Alan means joining a team of talented, committed, and passionate engineers, with a lot of product interaction.
The Stack
Python/Flask, React, React Native, PostgreSQL in a monorepo. We deploy daily and believe in distributed ownership – you build it, you own it.
Scope
- Hopper – Alan's own background coding agent: agent orchestration, parallel agent pools, web dashboard for builders
- AI-native engineering enablement – Harness integration, agentic workflows, …
- Autonomous testing infrastructure – agents that validate their own work before shipping
- Sandboxed development environments – removing brittle local setups so everyone can contribute safely
- CI/CD and quality guardrails – auto-fix, complexity scoring, automated checks and new PR review experiences that enable confident reviewing
- Non-engineer contribution tooling – flows and interfaces that make Designers, PMs and Ops autonomous contributors
Focus for 2026
In 2026, we’re moving from “AI tools you monitor” to “AI agents you trust.” That means scaling Hopper – Alan’s own background coding agent – alongside the infrastructure that makes it reliable: managed agent pools, sandboxed environments, autonomous testing, and CI auto‑fix. Engineers will routinely offload tasks to agents. Non-engineers will open pull requests after having easily tested their changes. Agents will validate their own work before it ships.
