Senior Software Engineer - Cards

Responsibilities

• Lead projects from idea to tech spec to implementation to launch, working with your PM, EM, tech lead, and teammates at each stage. When you lead a project, it's yours to see through.
• Learn how debit and credit cards actually work under the hood (authorization, clearing, settlement, disputes) and use that knowledge every day.
• Build features across the stack, from the card experiences customers use to the backend systems that move money.
• Help keep our operations excellent. Our systems are some of the most observable at Mercury, and with great observability comes great responsibility.
• Mentor other engineers and raise engineering quality through design reviews, code reviews, and collaboration.
• Work with product, design, operations, risk, compliance, sales, and many other teams.
• Have strong full-stack experience, a product mindset, systems thinking, and a knack for getting things across the line.
• Have made architectural decisions on complex systems, and be able to explain your reasoning and the trade-offs.
• Be excited to put new features in customers' hands, and care just as much about keeping existing ones working like a charm.
• Care about correctness in systems where failure has real financial consequences.
