Senior Java AWS Full-Stack Engineer

Randstad is seeking a highly skilled Senior Java AWS Full-Stack Engineer for a high-impact, hybrid role with a premier client in the Washington, D.C. / Wilmington area. As a core member of an Agile engineering team, you will drive the development and automation of complex backend applications, leveraging a modern AWS cloud-native ecosystem. This role offers a unique opportunity to bridge the gap between robust J2EE foundations and cutting-edge cloud architecture, requiring a developer who is equally comfortable writing high-performance Java code, architecting serverless functions, and leading end-to-end automation strategies within a Scaled Agile Framework (SAFe).

Architect & Develop: Design, develop, and maintain scalable backend services using Java and Spring Boot, transitioning legacy frameworks into modern, cloud-native architectures.

Cloud Implementation: Build and manage AWS-based solutions utilizing Lambda, Kinesis, DynamoDB, Aurora, and Redshift to ensure high availability and performance.

Automation & CI/CD: Implement and manage robust continuous integration and deployment pipelines using GitHub/GitLab, SonarQube, and automated testing suites.

Full-Stack Integration: Collaborate on the design and implementation of frontend JavaScript frameworks, ensuring seamless integration with backend APIs (REST/SOAP).

Quality Assurance: Lead TDD/BDD methodologies, writing comprehensive unit and integration tests using JUnit to maintain high code quality and security standards.

Agile Leadership: Participate in all phases of the SDLC, including active involvement in in-person PI Planning events and team meetings in the DC/Wilmington offices.

Expert Java Skills: Extensive experience with Spring Boot, Hibernate, J2EE technologies (Servlets, JMS, JDBC), and Object-Oriented design patterns.

AWS Specialization: Proven track record of developing cloud-native applications with a focus on serverless (Lambda) and managed database services (DynamoDB/Aurora).

Technical Breadth: Strong proficiency in Oracle/SQL, MQ, Web Services (SOAP/REST), and data formats including JSON, XML, and XSLT.

Security & Identity: Solid understanding of HTTPS, JAAS, Role-Based Security, and modern encryption techniques.

Modern Web Stack: Experience with JavaScript frameworks and a deep understanding of HTML/CSS within a full-stack context.

DevOps Mindset: Skilled in using Git-based version control and automated quality gates like SonarQube.

Location: Ability to work in a hybrid/remote capacity, with the flexibility to attend onsite meetings and PI Planning in Washington, D.C. or Wilmington.

Equal Opportunity Employer: Race, Color, Religion, Sex, Sexual Orientation, Gender Identity, National Origin, Age, Genetic Information, Disability, Protected Veteran Status, or any other legally protected group status.
