Role

Who you are

Has 7-10+ years of software development experience, with a strong focus on the backend, with a knowledge of or excitement to learn Haskell
Has been an experienced technical lead making architectural decisions in the past and seen the impact of those decisions over time. You should be able to clearly articulate your technical opinions and lay out tradeoffs
Is passionately product-minded and has experience building and shipping new products balancing reliability and velocity
Is someone comfortable driving discussions in areas with ambiguous ownership, approaches them with empathy, and delights in getting outcomes. Our work touches many other teams and areas of the product; you’ll have a lot of autonomy and the expectation is you’ll use that to seek out ways to have an impact
Is ridiculously helpful, taking initiative to make your coworkers’ lives easier by investing time to mentor and proactively share your knowledge and learnings through writings, 1:1s, and team meetings

What the job involves

Feel a strong sense of product ownership and actively seek responsibility – we often self-organize on small/medium projects, and we want someone who’s excited to help shape and build the future of Mercury Personal
Set the technical vision and lead the charge on architectural decisions, system design, and engineering best practices that shape the future of Mercury Personal and beyond
Collaborate closely with designers, product leaders, and other engineers to build new features for Mercury Personal and thoughtfully port existing business banking features over
Work across organizational boundaries to coordinate dependencies, reduce friction, and enable teams to deliver complex initiatives that span multiple domains

Our take

Frustrated by the archaic, fee-laden banking services offered to entrepreneurs, the founders of Mercury set out to create a better solution. They envisioned a platform that was dynamic, tech-driven, and free from unnecessary fees.

Mercury delivers on this vision by automating business payment processes, offering FDIC-insured accounts, and providing full API access, empowering entrepreneurs with greater control and efficiency. This approach stands in stark contrast to traditional startup banking, which often burdens young businesses with high fees and limited functionality.

By prioritizing user experience and offering a free service tier, Mercury has attracted over 200,000 businesses and achieved a $3.5B valuation as of 2025. As a rising unicorn in the stagnant world of startup banking, mercury is backed by substantial funding and poised for continued growth, constantly adding new features and expanding its team to further disrupt the industry.
