About the Role

We're looking for a Full Stack Software Engineer to join our team building modern, cloud-native applications. You'll work across the stack — from ReactJS front ends to Spring Boot microservices — while contributing to AI-driven features, workflow automation, and secure, role-based systems.

This role suits someone who thrives working independently, takes ownership of their deliverables, and enjoys collaborating across squads in an iterative delivery environment.

Key Responsibilities

• Design, build, and maintain web applications using ReactJS (Vite) on the front end and Spring Boot on the back end

• Develop and integrate REST APIs, and design data models using JPA and SQL

• Build and maintain microservices, with attention to scalability and maintainability

• Containerize applications using Docker for consistent deployment across environments

• Contribute to the development of an AI agent, integrating it into existing product workflows

• Work with AWS services (S3, SQS) to support asynchronous processing and file storage

• Implement local API mocking to support parallel front-end/back-end development and testing

• Write and maintain unit tests to ensure code quality and reliability

• Use Gradle and Git for build management and version control

• Implement BPMN-based workflows to support business process automation

• Build RBAC-driven UI components to enforce role-based access control across the application

• Work within AWS GCC (Government/Regulated Cloud environment) where applicable, adhering to relevant compliance and security standards
  

Required Skills & Experience

• Proficiency in ReactJS (with Vite tooling) and Spring Boot

• Strong understanding of JPA, SQL, and relational data modeling

• Experience designing and consuming REST APIs

• Hands-on experience with microservices architecture and containerization (Docker)

• Familiarity with AWS services, particularly S3 and SQS

• Experience with unit testing frameworks and test-driven practices

• Working knowledge of Gradle and Git

• Exposure to BPMN workflow engines (e.g., Camunda, Flowable, or similar)

• Experience implementing RBAC (Role-Based Access Control) in front-end applications

• Bonus: experience building or integrating AI agents into production systems

• Bonus: familiarity with AWS GCC or other regulated/government cloud environments
