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
- Experience in fintech, fraud systems, or the broader risk domain is a strong plus
What the job involves
- We’re looking for a Staff Software Engineer to contribute with building the systems and tools that make it all happen—from application approvals to ongoing and enhanced due diligence—ensuring every business that joins Mercury is both safe and their experience is delightful
- Lead the architecture, implementation, and long-term roadmap for core systems which support multiple fraud prevention use cases
- Own the end-to-end delivery of large cross-function projects, translating ambiguous high impact problems into strategy and execution, make pragmatic tradeoffs, and drive teams to measurable outcomes
- Design, build, and operate highly available, low-latency, backend systems that enable real-time scoring and decisioning for fraud prevention
- Partner with Data Science and ML teams to productionize models, build reliable ML data pipelines, and enable real-time model serving
- Establish and elevate department level best practices, review designs, drive engineering quality, and act as a trusted advisor on architectural tradeoffs
- Mentor and grow engineers, documenting learnings and sharing technical direction through writing, 1:1s, and team meetings
- Navigate and influence multiple stakeholders, help align teams, communicate tradeoffs to technical and non-technical partners, and independently resolve cross team issues
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, off the back of a $300 million Series C round, achieved a $5.2B valuation as of 2026. As a rising unicorn in the stagnant world of startup banking, Mercury is poised for continued growth, constantly adding new features and expanding its team to further disrupt the industry.
