Mid-Level Spring Boot Engineer

Nyla Technology Solutions•Annapolis Junction, MD

About The Position

We are seeking a high-performing Spring Boot & Data Modernization Engineer to join a collaborative, mission-driven team responsible for processing terabytes of operational enterprise data each week. In this role, you will enhance and scale a core Spring Boot application backed by MariaDB while driving its evolution toward modern containerization and Kubernetes orchestration. You will work across the full engineering spectrum—optimizing high-throughput database queries, designing RESTful APIs, refining Angular front-end interfaces, and automating CI/CD pipelines via GitLab. You will also have direct opportunities to shape architectural decisions, participate in DevSecOps practices, and cross-train across application, database, and deployment environments to build highly resilient systems.

Requirements

ACTIVE SECURITY CLEARANCE AT THE TS/SCI POLYGRAPH LEVEL IS REQUIRED
Demonstrated experience developing, debugging, and maintaining enterprise Java applications using Spring Boot or modern framework equivalents.
Proven ability to build, optimize, and maintain software that efficiently ingests, processes, and manages terabytes of operational data.
Strong hands-on experience working with relational database engines—specifically MariaDB, PostgreSQL, or Oracle—including query tuning and data access layer optimization.
Experience designing, developing, and maintaining secure RESTful APIs and building modern front-end web interfaces using Angular or similar frameworks.
Practical experience working with container technologies (Docker or Podman) and deploying containerized applications into Kubernetes-managed environments.
Hands-on experience utilizing GitLab CI/CD pipelines for automated builds and testing, along with Jira and Confluence for sprint planning and technical documentation.

Nice To Haves

Experience deploying applications to CNCF-compliant Kubernetes platforms such as Rancher, Amazon EKS, or OpenShift.
Familiarity with Kubernetes architecture components (Deployments, Services, ConfigMaps, Secrets, Ingress, Persistent Volumes) and Helm chart management.
Practical background in decomposing monolithic services into microservice architectures and guiding software evolution.
Experience providing backup DBA operational support (routine maintenance, monitoring, backup/recovery, and troubleshooting) for MariaDB, PostgreSQL, or Oracle databases.
Hands-on experience with automated test frameworks, DevSecOps pipelines, and continuous deployment workflows.
