Senior Software Engineer - Money Movement

Role Description

As a Senior Software Engineer on the Money Movement - Innovation team, you'll build the systems behind NMI's bank-to-bank payments:

• Public APIs
• Internal tools
• Third-party integrations

You'll use Scala, TypeScript, and C#, with TDD and containerized microservices on AWS (Docker, Lambda, ECS). You'll work AI-first, using tools like Claude Code daily and helping the team sharpen how it uses them. We're looking for someone who digs into ambiguous, high-stakes problems and owns them end to end.

About the team:

• The Innovation team sits at the center of NMI's money movement strategy.
• Formed through NMI's acquisition of Dwolla, we build and evolve the bank payment platform NMI's partners rely on, spanning open banking, push-to-card, account verification, and new payment rail integrations.
• We work asynchronously, communicate often, and expect blockers to be surfaced early.
• Psychological safety and continuous improvement are how we keep our high pace sustainable.

You will:

• Design and develop applications in Scala, TypeScript, and C#
• Use AI-first tools like Claude Code to research approaches, generate code, and strengthen review and testing
• Own code quality and production issues: reviews, bug reports, and troubleshooting
• Translate business needs into technical solutions with stakeholders and your team
• Participate in agile ceremonies (refinement, planning, standups, retros) and help improve how the team works
• Apply system design expertise across messaging (RabbitMQ), data at scale (SQL, S3), database/caching (RDS, Redis, DynamoDB), and CI/CD (Git, Jenkins, CloudFormation, Terraform)

Qualifications

• Strong grasp of programming languages, techniques, security, and architecture
• Ability to take ownership of assigned work and complete it without close oversight
• Experience with AI-first coding tools (e.g., Claude Code, Codex, Copilot)
• Experience mentoring and participating in code reviews
• 4+ years developing applications with object-oriented or functional languages
• Bachelor's degree in Computer Science (or related field), or 4+ years of additional equivalent experience

Requirements

• Working knowledge of distributed system design: event-driven microservices, containerized apps, service discovery
• Experience with Agile practices
• Experience with TDD and Continuous Integration
• Experience with paired programming or mobbing
• Experience with Scala, cats, or other functional programming tools and libraries
• Experience building and sharing AI skills or similar
• Exposure to ACH, payments, or other reliable/secure systems is a plus
