Job Description

Looking for a hands-on Lead Java Backend Engineer to help design, develop, and scale enterprise-level APIs and microservices supporting its AWS-hosted digital platform.
This is a technical leadership role on a team of approximately 12–13 engineers. The ideal candidate can drive architecture and design decisions, guide other developers, and take ownership of complex initiatives while remaining actively involved in hands-on backend development.
This is NOT a pure architect or people management role. Candidates must still be hands-on with Java/Spring Boot development.

Must-Have Requirements

• 10+ years of software engineering experience, including extensive hands-on Java backend development.
• Java 17+ (Java 21 preferred) and strong Spring Boot experience.
• Extensive experience designing and developing RESTful APIs and microservices.
• Strong AWS/cloud experience, including deploying and supporting production applications.
• Proven technical leadership experience involving architecture decisions, design reviews, code reviews, and mentoring engineers.
• Strong API design and integration experience; Apigee/API Gateway experience highly preferred.
• Experience with automated testing, CI/CD pipelines, and end-to-end software delivery.
• Must be able to work onsite in Chicago Mondays and Wednesdays.

Highly Preferred Technical Experience

• API Management: Apigee, OpenAPI/Swagger, API-first architecture.
• Security: OAuth 2.0, JWT, service-to-service authentication.
• Event-Driven Architecture: Kafka, AWS SQS/SNS/Kinesis, RabbitMQ, or similar.
• Databases: PostgreSQL, Oracle, MongoDB, DynamoDB, or similar SQL/NoSQL databases.
• CI/CD: Jenkins, Azure DevOps, GoCD.
• Testing: JUnit, Mockito, integration and performance testing.
• Additional: Redis, Elasticsearch, GitHub Copilot/Cursor, Agile/Scrum.

Candidate Screening Guidelines

Prioritize candidates who have

• Recent hands-on Java/Spring Boot development experience, not just architecture oversight.
• Experience functioning as a technical lead on enterprise backend/API projects.
• Strong AWS and microservices architecture experience.
• Stable work history with reasonable tenure.
