In the late 19th century, the electrical industry was rapidly expanding. However, it was heavily fragmented without standard voltages, frequencies, and plug types, making it difficult for consumers. The “War of Currents” emerged between proponents of DC, led by General Electric, and proponents of AC, led by Westinghouse Electric. With advancements in AC, pioneered by Nikola Tesla, engineers and executives of both companies came together to negotiate a new technical standard. They helped establish what is now known as IEEE (Institute of Electrical and Electronics Engineers) which provided a formal platform for developing and adopting industry standards. By the early 20th century, the collaboration led to the widespread adoption of 60Hz as the standard frequency for AC power in North America and the establishment of standardized voltage levels and plug types. This standardization was crucial for the rapid expansion of the electrical grid and the proliferation of electrical appliances and systems which consumers have benefited from for over a century.

Mercury is rapidly expanding and setting the new standard for what a business banking* platform can do for its customers. As we grow beyond traditional business banking into financial workflows, we must maintain a unified experience. Coming together with other product teams, we are passionately focused on ensuring our products not only meet but exceed the needs of our customers in a delightful way.

The Spend Management team is building products and platforms that redefine how companies implement processes and strategies to track, control, and optimize their spending. We’re a team of full-stack engineers motivated by the desire to create a lovable and intuitive product experience that brings a sigh of relief to our customers who are frustrated by existing complex and fragmented spend management solutions.

As part of this role, you will:

  • Feel a strong sense of ownership - driving the product from early concepts to launch and beyond, while keeping the user experience front and center in every decision
  • Drive architectural decisions and define the technical direction, while fostering alignment across the team and mentoring engineers toward those goals
  • Collaborate closely with product managers, designers, and other engineers to create intuitive, lovable experiences
  • Build core functionality in Haskell, ensuring the product is performant, maintainable, and scalable
  • Mentor and support more junior engineers on the team, raising the bar for technical excellence

The ideal candidate for the role:

  • Has 7-10+ years of software development experience, with a knowledge of or excitement to learn Haskell
  • Has made architectural decisions in the past and measured the impact of those decisions over time. You should be able to clearly articulate your technical opinions and lay out tradeoffs.
  • Is passionately customer and product minded and has experience building, shipping, and iterating on new products
  • 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 and doesn’t mind crossing team boundaries to improve the product experience and reduce tech debt
