Full Stack Developer
Position Summary
Softtek Government Solutions (SGS) is seeking an experienced Full Stack Software Developer to support the Congressional Budget Office (CBO) Full Stack Software Development Services task order. The developer contributes to the design, development, testing, and maintenance of web applications and supporting backend services that sustain CBO's internal workflows, analytical pipelines, and reporting capabilities.
The role spans the full application stack, Python/FastAPI backend APIs, ReactJS front-end interfaces, PostgreSQL databases, and Docker containers deployed to AWS and operates within CBO's trunk-based development workflow, contributing clean, reviewed, and well-documented code through frequent integration to the main branch. The developer participates in ongoing sprint cycles, planning and retrospective ceremonies, and delivers production-ready software on a continuous basis in close coordination with CBO's internal engineering team.
Responsibilities
Application Development & Feature Delivery
- Full-stack delivery: Design, develop, test, and deploy new features and enhancements across front-end (ReactJS) and back-end (Python/FastAPI) layers of CBO applications.
- API development: Build and maintain RESTful APIs using FastAPI, ensuring proper validation, error handling, versioning, and documentation (e.g., OpenAPI/Swagger).
- Front-end development: Develop responsive, accessible front-end interfaces using ReactJS, adhering to CBO UX standards and Section 508 accessibility requirements.
- Database engineering: Implement and manage data models, queries, migrations, and stored procedures within PostgreSQL databases, with attention to performance and data integrity.
Trunk-Based Development & Collaboration
- Trunk-based workflow: Operate within CBO's trunk-based development workflow, committing small, incremental changes frequently to the main branch to reduce integration risk and maintain a releasable codebase.
- Code review: Participate in code reviews, providing and receiving constructive technical feedback to maintain code quality and consistency.
- Stakeholder collaboration: Collaborate with CBO engineers, product owners, and analysts to understand requirements, refine user stories, and deliver working software iteratively.
- Branching standards: Adhere to CBO's branching, commit, and merge standards, including short-lived feature branches and feature flags where applicable.
Containerization & Cloud Deployment
- Containerization: Package applications and services using Docker, maintaining clean, minimal, and reproducible container images.
- AWS deployment support: Support deployment of containerized workloads to AWS environments (e.g., ECS, EKS, or equivalent managed services), working within existing cloud infrastructure patterns established by CBO's infrastructure team.
- AWS working knowledge: Demonstrate working knowledge of AWS services relevant to application hosting and operation, including EC2, S3, RDS, CloudWatch, IAM, and VPC networking concepts.
- Infrastructure collaboration: Collaborate with CBO infrastructure staff on environment configuration, secrets management, and cloud resource usage; write code that integrates cleanly into automated deployment pipelines without serving as a dedicated IaC/CI-CD engineer.
Maintenance, Bug Fixes & Technical Debt Reduction
- Defect resolution: Investigate, diagnose, and resolve application defects, performance issues, and security vulnerabilities across all layers of the stack.
- Refactoring: Proactively identify and address technical debt, refactoring code to improve maintainability, readability, and test coverage.
- Operational monitoring: Monitor application behavior and logs (e.g., via AWS CloudWatch or equivalent) and respond to operational issues as needed.
Testing & Quality Assurance
- Automated testing: Write and maintain automated unit, integration, and regression tests for both back-end (pytest or equivalent) and front-end (Jest, React Testing Library, or equivalent) code.
- Coverage requirements: Ensure new features and bug fixes are accompanied by appropriate test coverage prior to merge.
- UAT participation: Participate in functional and user acceptance testing in coordination with CBO stakeholders.
Documentation
- Technical documentation: Maintain accurate, up-to-date technical documentation for all developed systems, including API documentation, data model diagrams, architecture decision records (ADRs), and developer setup guides.
- Operational knowledge base: Document operational procedures, environment configurations, and known issues in CBO's designated knowledge management platform.
Qualifications
- Must be a US Citizen
- Demonstrated proficiency in the core technology stack: Python, FastAPI, ReactJS, PostgreSQL, and Docker.
- Sufficient familiarity with AWS cloud services (EC2, S3, RDS, CloudWatch, IAM, VPC) to deploy, monitor, and troubleshoot cloud-hosted applications.
- Experience writing automated tests (pytest, Jest/React Testing Library) and maintaining strong test coverage.
- Experience with trunk-based development, frequent integration, code review, and feature-flag-driven release practices.
- Working knowledge of front-end accessibility standards (Section 508).
- CI/CD pipeline concepts and IaC tooling familiarity (e.g., Terraform, GitHub Actions) desired but not a primary responsibility of this role.
Required Clearance
- Eligible for Public Trust Tier 2 suitability determination
