Mercury is building a bank and will be connecting our modern, product-focused engineering systems to enterprise core banking systems and payment networks built in a different era, with different assumptions and different interfaces. Our Banking Integration Platform as a Service team is like NASA’s RPOD team, building our integration subsystems that are technically correct and operationally trustworthy.

This is some of the most consequential infrastructure work at Mercury. Every account opening, every monetary transaction, and every balance call will flow through the systems you build. Product teams across the company will depend on clean abstractions that hide the complexity underneath. You'll be one of the few engineers at Mercury who truly understands the full depth of our Bank Core* and all its internal and external integrations.

In this role, you will:

• 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*.

You should:

• 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.
