Design, build, and ship new LLM‑powered Command features, creating tests with product and compliance to ensure they work correctly.
1‑4 years of backend or full‑stack experience, eagerness to learn Haskell, React, TypeScript, Redux, and prior work on LLM‑based products.
Command is Mercury’s AI financial assistant; expanding its capabilities directly enhances the core banking experience for all customers.
A product‑minded builder who thrives in ambiguous, startup‑like environments, empathizes with users, and actively uses AI tools to boost impact.
In 1965, an engineer in Scotland was given a mundane task with a tricky problem to it - banks wanted to close on Saturdays and still serve customers, but they didn’t know how to solve authentication of the right user. James Goodfellow, working at Smiths Industries, uncovered the insight that you needed something you have (a card) and something you know (a PIN). Because someone told him they could only remember 4 digits instead of his proposed 6, today over 3 million ATMs use a card+4 digit PIN over 60 years later.
Like the ATM, Mercury is building technology that pushes forward financial interfaces for the long term. Command is Mercury's LLM-powered financial assistant, launched to all customers in June 2026. It lets users understand their finances and take action in plain language, from asking about cash flow to sending payments, issuing cards, and managing invoices. With the product now in customers' hands, the work is to evolve it, extend its capabilities, and find new ways to leverage LLMs to give Mercury customers a more powerful banking* experience.
