Peraton offers enhanced benefits to employees working on this critical National Security program, which include heavily subsidized employee benefits coverage for you and your dependents, 25 days of PTO accrued annually up to a generous PTO cap and eligible to participate in an attractive bonus plan. Join a cross-functional Scrum team building mission-focused software in an Agile DevSecOps environment in our Herndon, VA location. As a junior engineer, you’ll contribute to full‑stack features, participate in acceptance criteria development, automate tests using Open Source/COTS tools, document instructions, and support integration activities. You’ll fix bugs, ship enhancements, and learn best practices while working with modern cloud, data, and messaging technologies. What You’ll Do • Build & deliver software in sprints: design, develop, test, document, and integrate features across front-end and back-end services. • Apply Agile engineering practices: participate in backlog grooming, sprint planning, daily standups, demos, and retros. • Support DevSecOps workflows: use Git-based workflows, CI/CD pipelines, and containerization to move changes from development to production. • Automate testing: create unit/integration tests and simple scripts to improve quality and repeatability. • Contribute to modernization: assist senior engineers in analyzing legacy ExtJS/Spring components and migrating to modern stacks and microservices. • Collaborate & learn: work closely with product owners, UX, QA, and other engineers; document technical work in Confluence and track tasks in Jira. Technologies You’ll Use (and grow into) • Front-end: JavaScript/TypeScript with React or Angular, HTML5, CSS3, responsive design; exposure to state management (Redux/NgRx) and modern build tools (Webpack, Vite, Angular CLI). • Back-end: Python 3.8+ (FastAPI or Flask), OR Java (Spring/Spring Boot); RESTful API design and OpenAPI/Swagger. • Messaging: Basic understanding of message brokers (e.g., ActiveMQ), JMS/STOMP concepts; integrating Python apps (e.g., stomp.py). • Data: PostgreSQL, MongoDB (schemas, indexing), and AWS managed databases (DynamoDB, DocumentDB). • Search & Analytics: Exposure to Elasticsearch (v8+)—index management, query DSL, analyzers/tokenizers, Python client usage. • Cloud & DevOps: AWS (EC2, S3), Docker, Kubernetes (foundational), CI/CD with Jenkins, GitLab CI or GitHub Actions; infrastructure-as-code (intro level). • Testing & Quality: JUnit, Pytest, Jest; familiarity with integration/E2E tools (Cypress, Selenium) and TDD concepts. • Security: Awareness of secure API design, OAuth2/JWT, CORS configuration, and OWASP-aligned practices.
