  • Collaborate with cross-functional teams to gather requirements, define technical solutions, and implement scalable and maintainable backend services.
  • Contribute to architecture discussions and support the design of new features, enhancements, and system improvements with a focus on performance, scalability, and reliability.
  • Build and enhance event-driven microservices and distributed messaging solutions using Apache Kafka for business-critical processing workflows.
  • Partner with DevOps teams to support build automation, deployment, monitoring, and continuous integration and continuous deployment (CI/CD) practices.
  • Create and maintain technical documentation including system designs, application programming interface (API) specifications, and implementation details.
  • Perform unit testing, integration testing, code reviews, and release support activities to improve software quality and delivery consistency.
  • Participate in Agile ceremonies and contribute ideas that improve engineering practices, team processes, and software quality.
  • Responsibilities listed are not intended to be all-inclusive and may be modified as necessary.

  • 5+ years of experience building backend services or microservices using Java, Spring Boot, Spring Batch, Spring Cloud Stream, or similar enterprise frameworks.
  • 5+ years of experience designing and developing RESTful application programming interfaces (APIs) with attention to security, scalability, and maintainability.
  • 5+ years of experience working with Apache Kafka or similar distributed messaging platforms in asynchronous or event-driven architectures.
  • 5+ years of experience working with containerization and orchestration technologies such as Docker and Kubernetes for application deployment, scaling, and troubleshooting.
  • Experience with relational and non-relational databases such as MySQL, MongoDB, or similar platforms, including data access and query optimization.
  • Experience using Git and modern continuous integration and continuous deployment (CI/CD) tools in Agile software delivery environments.
  • Bachelor's degree in computer science, software engineering, or a related field, or equivalent combination of education, related experience and/or military experience.

Experience that would be great to have:

  • Experience with distributed systems design and high-volume event processing.
  • Experience with cloud-native application deployment and observability practices.
  • Experience with Scrum or other Agile delivery frameworks.

Individuals with temporary visas including, but not limited to, F-1 (OPT, CPT, STEM), H-1B, H-2, or TN, or any candidate requiring sponsorship, now or in the future, will not be considered for this role.
  • We're better together. This role is fully on-site.
  • This is a full-time, direct-hire position, and no contract options for unsolicited agency submissions will be considered.
