Senior Software Engineer

About the role

We're looking for a Senior Software Engineer to build backend systems that power billions in transaction volume across 180+ countries. This is a backend-heavy role focused on secure, reliable value transfer across blockchain and traditional banking protocols. Multiple teams are hiring for areas including liquidity, payments, developer tooling, and stablecoin operations.

Responsibilities

• Own and extend microservices responsible for secure, reliable value transfer across blockchain and traditional banking protocols
• Design APIs used by developers worldwide
• Integrate with major banks and financial platforms
• Collaborate closely with product and engineering on architecture and system design
• Lead small technical teams (2–4 engineers) on architecture and design decisions

Requirements

• 6+ years of professional software development in object-oriented languages; deep Java expertise is the primary requirement (Go is used but secondary; C#/.NET-centric backgrounds are not a fit)
• Solid background in payment systems — credit cards, bank transfers, payment rails
• Strong RESTful API design and development fundamentals
• Experience with cloud platforms (AWS, GCP, or Azure) and SQL schema design
• CS degree or equivalent
• Must be US-based with meaningful Pacific Time availability (this team operates on PT and overlap is required)

Qualifications

• Web3/blockchain exposure is a plus, not a requirement

Pay

$150,000 – $200,000 base + equity. Compensation is flexible for the right person.
