Role Description

We're looking for a Senior Software Engineer to help build the financial infrastructure behind Fold. You'll design, build, and scale backend services that power payments and real-time transaction processing. This is a chance to have an outsized impact at a company where your technical decisions shape the trajectory of the product.

Day to day, that means:

• Designing and implementing scalable, reliable backend services that handle real-time transaction processing
• Building and evolving event-driven systems for processing financial events
• Integrating with external partners — card processors, banking APIs, payment networks
• Owning features end-to-end, from technical design through deployment and monitoring
• Collaborating closely with product, design, and fellow engineers to ship quickly and iteratively
• Mentoring other engineers through code reviews, pairing, and architectural guidance
• Improving engineering practices, tooling, and infrastructure as the team grows

Qualifications

• 5+ years of professional software engineering experience with strong proficiency in Java or a similar statically-typed language (Kotlin, Scala, C#)
• Experience building and operating production microservices and distributed systems
• Experience with messaging or event streaming systems (Kafka, Pulsar, or similar)
• Solid understanding of relational databases with an intuition for data modeling and transactional consistency
• Comfort working with cloud infrastructure, CI/CD pipelines, and containerization
• Experience scaling systems in a fast-paced, growth-stage environment
• Strong communication skills and a collaborative, low-ego mindset

Requirements

• Experience with financial systems, payment processing, or ledger/accounting domains
• Familiarity with event-driven architectures, CQRS, and event sourcing patterns
• Experience with Micronaut, Quarkus, or similar modern Java frameworks
• Passion for Bitcoin
• You're already a Fold user
• Candidates must have permanent legal authorization to work in the United States. Visa sponsorship is not available for this position.

Benefits

• We’re a highly collaborative, fully remote team
• Flexible work schedule, including flexible time off
• Competitive salary
• Equity package
• 401k with employer match up to 3%
• Yearly vacation stipend
• Comprehensive health, vision and dental insurance, including HSA and FSA accounts
• Paid parental leave
• Regular in-person team meetups to socialize and co-work
• New to Bitcoin? We offer all our new hires a “starter pack” to get you up to speed, including learning materials about Bitcoin and your own hardware wallet.
• And much, much more!
