Overview

The Mission

​The mission of the Sr. Java Developer is to provide comprehensive technical leadership and hands-on application development for the company’s secure, enterprise-level software systems. As a Senior Java Developer, you will drive technical leadership and hands-on application development for our secure, enterprise-level software systems. You’ll serve as a key technical authority and execution lead—bridging high-level architecture with daily engineering. This role is based out of one of our two primary hubs, located just 10–15 minutes from either El Segundo, CA or Seal Beach, CA.

​We are explicitly seeking an operationally driven software leader who manages from the front lines—someone who views active coding and system architecture as their primary command center. Stepping into this position, you will lead complex application features, oversee daily development workflows, mentor team members, and build scalable REST and SOAP services within cloud environments. By combining deep mastery of Java frameworks with a project-focused approach, you will support strategic business goals and drive continuous improvement across the full software development lifecycle (SDLC).

  • Environment Management: Oversee application development infrastructure across local and cloud environments, including build tools, version control, and database maintenance.

​Technical Leadership & Project Execution

  • Team Enablement: Coach and build technical capabilities across cross-functional engineering teams, maintaining high workflow efficiency and project accountability.

  • Cross-Functional Collaboration: Partner seamlessly with cross-functional project teams, DevOps, QA personnel, and executive stakeholders across both locations.

​Technical Innovation & Client Support

  • Technical Interface: Serve as a primary technical SME for internal and external stakeholders, clarifying complex software behaviors and delivering technical updates.
  • Capability Growth: Drive technical improvements and identify opportunities for tool automated testing, CI/CD integration, and high-performance cloud solutions.

​Profile of Excellence

  • Hands-On Development Leader: A proven developer who believes authentic leadership comes from deep technical involvement. You remain active in writing code, conducting peer reviews, and stepping into the IDE alongside your team.
  • Framework Mastery: Deep, practical familiarity with core Java frameworks and enterprise design patterns, with an explicit focus on the Spring Framework, Hibernate, and web service architecture.
  • Agile & Quality Centered: A natural mentor who utilizes structured Agile/Scrum practices to build team technical competency and maintain an organized engineering workflow across sites.
  • Strategic Partner: A technical professional capable of balancing tight software accuracy with project deadlines, clearance constraints, and multi-site operational efficiency.
