• Proven experience designing and building RESTful APIs and microservice architectures
• Hands-on experience working in AWS cloud environments
• Familiarity with containerization (Docker, Kubernetes) and DevOps practices
• Hands-on experience with AI-assisted engineering tools (e.g. Claude Code, Cursor, or similar) — required
• Strong sense of ownership, quality, and accountability
• BS in Computer Science, Engineering, or equivalent practical experience
• Good level of spoken and written English: able to communicate technical topics effectively across distributed teams
• Working hours: Pacific Standard Time - Full time

Preferred Qualifications

• Background in regulated or compliance-driven systems is a plus
• Exposure to event-driven architectures and message queues
