Mercury is a financial technology company that provides online business banking services, although it is not a bank itself. It partners with FDIC-insured banks like Choice Financial Group, Column N. A. , and Evolve Bank & Trust to offer banking services. Mercury aims to simplify financial operations for startups and businesses by offering a range of services including checking and savings accounts, treasury management, corporate cards, expense management, invoicing, and accounting automations. The platform is designed to streamline various banking tasks and enhance financial workflows with features like fraud monitoring and account security. It also offers investment opportunities through its Mercury Treasury product and startup support through its Mercury Raise platform.

📋 Description

• Build Mercury’s integration with an FFIEC-approved bank core and the connections to payment networks. • Design internal APIs that give product teams simple, consistent interfaces to complex external systems. • Handle the messy realities of enterprise integrations such as retries, failures, format mismatches, and downtime. • Build data pipelines that keep Mercury's systems in sync with our bank core. • Own monitoring, alerting, and recovery for our most critical external connections. • Partner with many other teams at Mercury to define clean boundaries and reliable contracts. • Help shape the technical architecture of Mercury Bank.

🎯 Requirements

• Have direct experience with either a bank core that has achieved FFIEC-compliance (such as FIS) or that of a US-based Global Systemically Important Bank (G-SIB). • Understand how core banking systems work: accounts, transactions, ledgers, and the data models underneath. • Be a product-minded engineer who thinks about the developers consuming your APIs, not just the systems you’re connecting to. • Thrive in environments where you're building something new rather than maintaining something established. • Be comfortable with our tech stack (Haskell and TypeScript) or ready to learn. • Have strong opinions about building reliable, maintainable systems.

🏖️ Benefits

• The total rewards package at Mercury includes base salary, equity, and benefits. • Our salary and equity ranges are highly competitive within the SaaS and fintech industry and are updated regularly using the most reliable compensation survey data for our industry.
