Job Description:

Parsons is looking for an amazingly talented Junior full-stack software engineer to join our team! In this role, you will contribute across the full software development life cycle—from component/page design to back-end architecture, implementation, and verification testing—supporting mission-critical applications and products. You will help deliver scalable, secure, and elegant solutions in collaboration with multidisciplinary teams. 

This position is an in-office position and does not allow for remote work. Work is extremely hands-on and requires full, end-to-end software/hardware testing. 

What You'll Be Doing: 

• Build and maintain scalable front-end interfaces and back-end services. 

• Optimize performance for both UI responsiveness and data processing workflows. 

• Implement CI/CD pipelines and containerized deployments using Docker. 

• Conduct peer code reviews and ensure unit, integration, and regression test coverage. 

• Collaborate with UI/UX designers, system architects, program managers, and stakeholders. 

• Apply Agile/SAFe methodologies and maintain clear documentation of codebases and processes. 

What Required Skills You'll Bring: 

• U.S. Citizenship and ability and willingness to obtain a TS/SCI. 

• Bachelor’s degree in computer science or a related field (or 4 years of additional experience in lieu). 

• 3+ years of experience in software development in either front-end or back-end technologies. 

• Strong programming skills in a few of the following:  ReactJS, Java, JavaScript, C++, and SQL. 

• Develop RESTful APIs and microservices using modern frameworks. 

• Expertise in containerized application development and management. Preferably with a strong familiarity of Docker, including deploying, managing, and scaling containerized applications, as well as troubleshooting and optimizing workloads within a cluster. 

• Proficiency with RESTful API design, data visualization, database architecture (SQL/NoSQL), and version control (Git). 

• Experience with front-end frameworks and responsive design principles. 

• Strong debugging and performance optimization skills for distributed systems. 

What Desired Skills You'll Bring: 

• Experience with message brokers: AMQ, ZMQ, or RabbitMQ.  

• Familiarity with PostgreSQL, or any SQL database framework.  

• Knowledge of DevSecOps practices and tools (e.g., GitLab CI/CD, Jenkins, Terraform, Ansible, Artifactory).
