Senior Java​/API Engineer

Location:

Chandler, AZ (onsite, 3 days/week)

Level: 7+ years of experience

Engagement: W2 through Randstad Digital

You’ve built API platforms from the inside, not from a whiteboard. We need someone who can own the architecture of an enterprise API gateway program, set patterns the rest of the org will follow for years, and still throw down code when a complex integration calls for it.

• Lead architecture and design for an enterprise API gateway program serving dozens of downstream teams
• Define API standards, governance, and security patterns across the organization
• Build reference implementations and reusable libraries that scale across teams
• Drive performance, resiliency, and observability strategy for the gateway layer
• Mentor mid-level Java engineers and grow the bench
• Partner with security to enforce zero‑trust and least‑privilege at the API layer

• 7+ years of Java engineering, with 3+ years focused on API gateway / API platform work
• Deep Spring Cloud, Spring Boot, and microservices architecture experience
• Strong understanding of authentication, authorization, and API security patterns
• Hands‑on with at least one major API gateway at production scale (Apigee, Kong, APIM, etc.)
• Experience leading architecture for high‑throughput, low‑latency systems
• Track record of mentoring and leveling up other engineers
• Experience in financial services or another regulated industry
• Event‑driven architecture experience (Kafka, Pulsar)
• Published patterns, talks, or open‑source contributions in the API space

You’ll be the technical anchor for how a Fortune 50 bank exposes its capabilities to the rest of the business. The decisions you make show up in every product the company ships.
