Location: St. Louis, MO| Onsite 

Salary: $70-75/hr on C2C 

JD

We are looking for a staff‑level software engineer / architect to lead the modernization of a largescale, mission‑critical Java platform. This role is hands‑on and focused on rewriting and re‑architecting existing systems using modern Java, Spring Boot, and cloud‑native patterns on AWS.

 

What You’ll Do

• Modernize a legacy Java platform to Java 21 and Spring Boot
• Re‑architect monolithic components into well‑structured, cloud‑native services
• Design and build services for AWS EKS and/or OpenShift
• Define execution models, service boundaries, and deployment patterns
• Drive architectural decisions around performance, scalability, and reliability
• Work closely with platform, DevOps, and cloud infrastructure teams
• Mentor senior engineers and set engineering standards
• Own solutions end‑to‑end — from design through production

 

What We’re Looking For

• Staff‑level experience building and modernizing large Java systems
• Strong hands‑on experience with Java (17+ preferred, 21 ideal) and Spring Boot
• Deep understanding of distributed systems and system design
• Practical experience deploying applications on AWS, preferably EKS
• Solid Kubernetes knowledge (EKS and/or OpenShift)
• Experience containerizing applications and running them on a scale
• Strong grasp of performance tuning, JVM behavior, and low‑latency systems
• Ability to operate as both architect and hands‑on engineer

 

Nice to Have

• Experience migrating from monoliths to cloud‑native architectures
• Exposure to eventing, messaging, or streaming systems (Kafka, MQ, etc.)
• Familiarity with CI/CD pipelines and infrastructure‑as‑code
• Background in financial services, payments, or high‑throughput systems

 

Why This Role

• Opportunity to shape the future architecture of a critical platform
• Work on complex, high‑scale systems where design decisions matter
• High ownership, real technical impact, and long‑term relevance

Thanks & Regards,

Irfan Shaik
