What the job involves
- We’re looking for an experienced Software Development Engineer in Test (SDET) to join our Software Quality team and help lead our test automation strategy across the Mill ecosystem — spanning embedded firmware, mobile apps (iOS/Android), web, and cloud platforms
- This role will play a key part in shaping our end-to-end quality strategy and building the frameworks that ensure reliability and scalability in our rapidly evolving products
- Collaborate closely with the engineering team to design and develop Mill’s automated test infrastructure
- Design, implement, and scale automation frameworks covering embedded firmware, mobile applications, web, and cloud services
- Interface with cross-functional leaders (Product, QA, Engineering, TPMs) to translate product requirements and feature requests into well-defined, structured test plans
- Drive automation initiatives — mentor QA engineers, explore emerging tools, and champion best practices in test engineering
- Establish and maintain reliable processes and tooling for test script development, integration, and execution
- Partner with Developers, QA Engineers, Firmware Engineers, Software Engineers, Product Managers, and TPMs to ensure robust end-to-end product quality across all layers of the stack
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.
