Full Stack Java Developer Jobs in Leominster, MA

Req ID: 136120
Remote Position: Yes
Region: Americas
Country: USA
Summary
We are seeking an experienced full-stack GUI software developer to design, develop, and test the next-generation AI-enabled automation infrastructure for switches and integrated data center racks. This is not a traditional "scripting" role; you will be building a full-stack, SDLC-integrated, test-driven engineering ecosystem centered around products running SONiC (Software for Open Networking in the Cloud) and OpenBMC within hyperscaler racks.
Your mission, collaborating with the larger DevTestOps Team and software development teams, is to build an immersive, intuitive, robust, and full-featured control center for managing world-wide network automation test infrastructure. The Test Automation Control Center will consist of a set of cloud-hosted applications controlling multiple physical on-prem systems distributed worldwide. Control capabilities cover scheduling, monitoring, analyzing, and reporting tests from the initial developer Pull Requests to the final release regression validation. Managed equipment includes the entire range of Celestica switches, high-performance IXIA traffic generators, and a variety of equipment commonly found in data center racks. You will use your knowledge of AI agents to integrate intelligent workflows that select the best automation test cases to run, diagnose test failures for rapid resolution, and analyze test coverage to provide predictive product quality assessment.
Detailed Description

• 
  Architect & Design: Lead the design and implementation of a robust, cloud-hosted GUI that provides a seamless user experience for managing physical on-prem systems distributed globally.
  
• 
  Full-Stack Development: Build and maintain the entire engineering ecosystem, ensuring it is test-driven and fully integrated into the CI/CD pipeline.
  
• 
  AI Integration: Implement AI-driven workflows to intelligently select automation test cases, perform automated failure diagnostics, and provide predictive product quality assessments.
  
• 
  Infrastructure Management: Develop user interface control capabilities for managing complex hardware, including Celestica switches, IXIA traffic generators, and diverse data center rack equipment.
  
• 
  End-to-End Visibility: Create reporting and analysis tools that track code health from the initial Pull Request to final release regression validation.
  
• 
  Collaboration: Work closely with DevTestOps and software development teams to ensure the control center meets the evolving needs of our global network infrastructure.
  

Knowledge/Skills/Competencies

• 
  Expert GUI Development: Proven experience building complex, data-rich graphical user interfaces using modern frameworks (e.g., React, Vue.js, or Angular).
  
• 
  Testing Infrastructure: In depth experience with GUI automation frameworks, such as Playright, Cypress, or Selenium.
  
• 
  Full-Stack Proficiency: Strong backend experience (Node.js, Java Script, Python, or Go) with a focus on cloud-native architectures and SDLC integration.
  
• 
  Networking & Hardware Context: Familiarity with high-performance networking environments, specifically SONiC, OpenBMC, and data center hardware management.
  
• 
  AI/ML Application: Practical experience integrating AI agents or LLM-based workflows into software applications to automate decision-making and analysis.
  
• 
  Engineering Rigor: Deep understanding of test-driven development (TDD), CI/CD pipelines, and robust software engineering practices.
  
• 
  Systems Thinking: Ability to bridge the gap between cloud-hosted software and physical hardware distributed across global sites.
