Software Developer

BLN24 is seeking a Junior Software Developer to support NOAA’s modernization of mission-critical weather and data dissemination systems. Working as part of an Agile development team and with mentorship from senior engineers, the developer will help review legacy weather applications, which typically ingest, route, and deliver weather products, and convert them into secure, event-driven, cloud-native applications on AWS in support of the National Weather Service. The ideal candidate is eager to learn modern cloud technologies, enjoys solving technical challenges, and thrives in a collaborative environment delivering solutions that improve NOAA’s capabilities. Role and Responsibilities:

• Develop and maintain backend services and REST APIs (primarily Python) that carry forward legacy application workflows, including administrative and subscription-management functions.

• Build and update user-facing features using modern front-end technologies (e.g., React) that work across a wide range of browsers and devices.

• Develop event-driven, message-processing components on AWS (e.g., Lambda, SQS, S3) and the data-access layer for relational databases.

• Study legacy code and documentation to understand how existing systems behave, and help write design documents, API contracts, and workflow diagrams that preserve that behavior in the cloud version.

• Add structured logging, audit trails, and correlation-ID tracing so issues can be followed across components.

• Write automated tests, test simulators, and mocks, and contribute to CI/CD pipelines, including security-scan gates.

• Fix security findings and vulnerable dependencies, following least-privilege access practices and government security requirements.

• Contribute to application deployments and AWS infrastructure under the guidance of senior engineers.

• Collaborate with teammates, QA, DevSecOps, and government stakeholders, and participate in demos and knowledge-transfer sessions.

• Education and experience: Bachelor’s degree or Bachelor’s degree in-progress in Computer Science, Software Engineering, or a related field

• Back-end development: Experience building backend services or APIs in Python, or in another server-side language (e.g., Java or C#/.NET) with the ability to learn Python quickly.

• Databases: Working knowledge of SQL and relational databases (e.g., PostgreSQL, SQL Server, or MySQL).

• Testing: Experience writing automated unit tests (e.g., pytest or similar).

• Tools and processes: Experience with Git and familiarity with agile development practices.

• Cloud: Exposure to AWS or another cloud platform through work, coursework, personal projects, or certification.

• U.S. Citizenship Required: Proof of U.S. Citizenship and eligibility for Public Trust clearance.

Other Desired Skills/Abilities, Experience

• Front-end experience with JavaScript (ES6+), HTML5, and CSS3, and a modern framework (e.g., React, Angular, or Vue.js).

• Hands-on experience with AWS services such as Lambda, S3, SQS, ECS, EC2, or RDS.

• AWS certification (e.g., Cloud Practitioner or Developer - Associate).

• Familiarity with Python web and data frameworks (e.g., FastAPI, SQLAlchemy).

• Experience with database design and query optimization in PostgreSQL or SQL Server.

• Experience with integration testing and CI/CD pipelines.

• Familiarity with Infrastructure as Code (e.g., Terraform, CloudFormation).

• Familiarity with Docker and containerized environments (e.g., ECS or Kubernetes).

• Experience reading and modernizing legacy code (e.g., Java, C/C++, or C#/.NET).

• Experience with application security practices such as vulnerability remediation and secrets management.

• Experience with logging and observability tools and practices.

• Familiarity with federal government environments.

• Experience using AI-assisted development tools (e.g., GitHub Copilot, Claude, ChatGPT) responsibly, within security and data-handling policies.
