Company mission
To make scaling tech companies simpler with a personalized banking stack for startups, and power the next generation of companies that will shape the American industry.
Role
Who you are
- Seven or more years of backend software engineering experience
- Proven experience leading technical projects at scale, including planning, execution, and stakeholder management
- Experience maintaining and improving legacy systems
- Clear and persuasive communication skills — you can articulate tradeoffs and influence decisions across teams, communicating clearly with non-technical stakeholders
- A mindset that balances urgency with craftsmanship: shipping fast, without cutting corners on quality engineering
- Creativity and adaptability — you think beyond the obvious and find solutions that move both product and business forward
- A track record of mentoring engineers and helping teams grow
What the job involves
- Domestic Wires plays that role at Mercury. We own the engineering behind secure, compliant, and reliable domestic wire transfers — enabling businesses to move significant amounts of capital with precision and trust
- The systems we build must balance speed with safety, scale with strict controls, and product flexibility with regulatory requirements
- As a Senior Engineer, you’ll operate at the core of Mercury’s money movement platform
- You’ll design and evolve high-reliability systems, influence technical strategy, partner across product, risk, and banking* teams, and mentor others as we scale
- This is an opportunity to work on infrastructure where durability, clarity, and strong judgment matter as much as raw speed
- Lead Projects End-to-End: Drive technical projects from concept to production. Define solutions, analyze tradeoffs, make critical decisions, and deliver software that works today and is sustainable for tomorrow
- Collaborate Across Functions: Partner with product, design, and business stakeholders to shape initiatives. Translate between technical and non-technical audiences to ensure clarity, alignment, and buy-in
- Code Craftsmanship: Write clear, testable, and maintainable code. Establish patterns and best practices that your team can follow, ensuring long-term scalability and reliability
- Build for Quality & Sustainability: Design extensible systems, make balanced decisions on tech debt, plan careful rollouts, and own the quality of your work through post-launch monitoring
- Think Product, Not Just Code: Approach problems with a product mindset. You care as much about the business impact of what you build as the technical design
- Mentor & Elevate: Coach engineers on your team by sharing patterns, practices, and critical thinking to raise the technical bar and foster a culture of sustainable engineering
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.
