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. \nLike 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.\nWhat You'll Do:\nShip new capabilities users love\nFeel a strong sense of product ownership and actively seek responsibility - help design and ship new Command skills\nPartner with product and compliance teams to define what \"working correctly\" means for each new capability, then build the tests that prove it\nJoin a small but mighty team of experienced product and AI engineers building the future of Mercury\nThis list is illustrative. Command is a product in motion and priorities will shift as we learn. The right person should be comfortable working in ambiguity, in a scrappy startup environment\nThe Ideal Candidate:\nHas 1-4 years of backend or full-stack development experience, with knowledge of or excitement to learn Haskell, React, TypeScript, and Redux\nExperience building LLM powered products\nA builder who is passionately product-minded and has experience building and shipping new products\nEmpathizes with users and can channel their perspective to build lovable products\nCan balance tradeoffs and find creative solutions to accomplish goals\nActively incorporates AI tools into their workflow and is excited about leveraging them to amplify their impact - whether that's accelerating development, improving code quality, or finding creative solutions to hard problems\nIf this role interests you, we invite you to explore our public demo at demo.mercury.com.\nMercury values diversity & belonging and is proud to be an Equal Employment Opportunity employer.
