Junior Full Stack Software Engineer (DevSecOps)

Responsibilities

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.

Qualifications

Required Qualifications

• A Bachelor’s degree in an area applicable to the position with 2+ years of relevant experience OR a Master’s degree in an area applicable to the position; an additional 4 years of experience maybe considered in lieu of a degree requirement.

Desired

• Front-end state management (Redux, NgRx); modern build tooling (Webpack, Vite, Angular CLI).
• Python async/await and ASGI servers (Uvicorn/Hypercorn).
• Elasticsearch basics (indexing, query DSL) and Python client usage.
• MongoDB schemas, aggregation pipelines, performance tuning; drivers (PyMongo or Motor).
• Message broker familiarity (ActiveMQ, JMS/STOMP).
• CI/CD pipelines (Jenkins, GitLab CI, GitHub Actions); infrastructure-as-code (Terraform/CloudFormation).
• Kubernetes fundamentals; container orchestration patterns.
• Legacy analysis/migration: ExtJS and Spring to modern microservices/API gateway patterns.
• E2E testing (Cypress/Selenium); integration testing strategies.
• Collaboration tooling (Jira, Confluence); code reviews and branching strategies.
• Monitoring/observability awareness (Prometheus, Grafana, ELK).

Soft Skills
