- Strong backend development skills, ideally using Python

- Solid understanding of API design, asynchronous communication patterns, and robust error handling
- Familiarity with CI/CD systems (e.g., GitHub Actions, CircleCI), build tooling, and code quality enforcement (e.g., linters, formatters, testing frameworks)
- Passion for system reliability, including observability, alerting, tracing, and performance optimization
- Excellent communication skills and comfort working in a collaborative, product-focused environment
Desirable
- Deep mobile experience: Native Modules, Bluetooth Low Energy (BLE), deep links, react-navigation, Tailwind CSS, websockets, and Fastlane
- Experience with feature flagging systems such as LaunchDarkly or Eppo

Our take
Wasted food and its decomposition do more for CO2 emissions globally than the entire airline industry combined. Whilst food waste bins run by local councils in the US do redirect the majority of food waste to recycling plants, there are still holes to plug, which is exactly what Mill is doing.
For a yearly subscription, customers can buy and use a combined waste tracking and impact app alongside the company’s purpose-made food waste bin. Unlike other bins for food waste, Mill’s product shrinks and dehydrates waste so that there’s no smell or runoff. Mill will dispose of your waste themselves, and use it for sustainable chicken feed.
With a number of high profile environmentally-friendly investors behind them, the Mill ecosystem has a range of benefits for company subscribers as well as individuals. Restaurants and offices can subscribe to Mill and help to move towards sustainability goals, whilst partnerships with local farms provide a solid revenue structure.
Mill is only available in the US, but since its successful first-gen launch in 2023, it has been using funding from that year to enhance its product offering and reach a wider market.
