Staff Software Engineer

Job Description

Senior / Staff Software Engineer, Banking Platforms

Location: NYC - hybrid, 3 days in the office

The opportunity

A small senior team is building a new financial platform for large institutions. The product uses AI where it helps. It also handles money, so accuracy comes first.

The team moves with startup speed and autonomy. An established parent organization provides enterprise resources and stability. You get real ownership and the resources to do the job well.

What you build

• Services that hold accounts, record transactions and move money
• Workflows that run reliably and recover from failure
• Controls that enforce regulatory rules
• APIs, events and data contracts that other teams trust
• Monitoring, alerting and recovery for the services you run

How you work

• You own your services from design to production, including on-call
• You choose the simplest design that meets today’s need and holds up later
• You use AI tools and agent workflows where they improve results
• You mentor engineers and share what you learn

What you bring

• 5 to 15 years of software engineering experience
• Production experience building distributed systems in a compiled language such as Go, Java, Kotlin or Rust
• Experience with message streaming, such as Kafka or similar
• Clear reasoning about concurrency, data consistency, retries and partial failure
• A record of running critical systems in production: incidents, monitoring, rollbacks and recovery
• Comfort with automated testing and modern deployment practice
• Daily use of AI tools, with you accountable for the design, testing and security of what ships

Why join

• Your work runs at large financial institutions
• A small, senior team with high autonomy and accountability
• Systems where quality matters and your impact is visible
• Startup pace with the stability of a larger organization
