About this role
Mercury is a fintech company that is building a modern bank and is seeking a Senior Software Engineer for their Banking Integration Platform team. The role involves building and maintaining integrations with banking systems and payment networks, designing internal APIs, and ensuring the reliability of external connections.
Responsibilities:
- 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:
- Has 7+ years of professional software engineering experience building and operating backend infrastructure and distributed systems at scale
- Has experience integrating modern distributed software systems with older, legacy infrastructure, preferably in a highly-regulated environment
- Has an understanding of how banks and banking systems work: accounts, transactions, ledgers, and the data models underneath
- Is a product-minded engineer who thinks about the developers consuming your APIs, not just the systems you're connecting to
- Thrives in environments where you're building something new rather than maintaining something established
- Is comfortable with our tech stack (Haskell) or ready to learn
- Has strong and justified opinions about building reliable, maintainable systems
