- Build responsive, performant user interfaces using React and TypeScript
- Design, implement, and maintain RESTful APIs using Java, Python, and Node.js
- Create and maintain API documentation using Swagger/OpenAPI
- Develop and operate containerized services using Docker and deploy on Kubernetes (EKS)
- Configure, maintain, and optimize CI/CD pipelines (Drone CI, Jenkins, Spinnaker)
- Monitor system health, performance, and reliability using logging, metrics, and observability tools
- Debug production issues and lead root cause analysis across distributed systems
- Integrate and support third-party systems, including payment platforms (e.g., Stripe)
- Collaborate cross-functionally with Product, Design, and DevOps to deliver end-to-end solutions
- Enforce best practices for Git workflows, code reviews, and release management
- Define and uphold microservices principles, including service boundaries, scalability, and system integrations
- 8+ years of professional software engineering experience with demonstrated impact on complex, distributed systems
- Strong full-stack experience across modern frontend and backend technologies
- Proficiency in systems thinking, including modeling system behavior, understanding trade-offs, and anticipating downstream effects of architectural decisions
- Deep understanding of distributed systems, microservices patterns, and API design
- Hands-on experience with AWS, including S3, EKS, WAF, Cost Explorer, and Bedrock
- Experience integrating with Salesforce (SFDC) or PROS APIs is preferred
