- Proficiency with TypeScript and Node.js (Python and Java/Spring familiarity for legacy support)
- Hands-on experience with AWS in serverless and event-driven architectures
- Proven experience owning production systems, including monitoring, troubleshooting, and incident response
- Strong understanding of RESTful API design and distributed system patterns
- Ability to work autonomously and take ownership of large bodies of work
- Strong collaboration and communication skills in cross-functional environments

- Experience with financial services, payments, or money-movement platforms (transfers, P2P, bill pay)
- Experience with API management platforms such as Kong or Apigee
- Infrastructure as Code experience (Terraform)
- Experience with multi-region deployments and blue/green release strategies
- Familiarity with Apache Camel, SOAP integrations, or hybrid REST/SOAP environments
