What are the responsibilities and job description for the Software Developer-Mid position at ECS Federal, LLC?

ECS is seeking a Software Developer-Mid to work in our Fairfax, VA office / remote.

ECS is seeking talented professionals to join our successful and growing team in building the next-generation Continuous Diagnostics and Mitigation (CDM) Cyber data solution. The CDM Program is the Cybersecurity and Infrastructure Security Agency's (CISA) dynamic approach to strengthening the cybersecurity of Federal networks and systems through better awareness and visibility into their security posture and cyber threats. ECS is responsible for designing, building, deploying, operating, and maintaining a complete ‘Data Services' solution which includes the collection, normalization, visualization, and sharing of cyber data from more than 100 Federal agencies. The CDM Data Services product is an integrated suite of multiple Commercial Off the Shelf (COTS) products, software configuration packages, and custom code which work together to operate as an integrated solution tailored to meet Department of Homeland Security (DHS) requirements.

We are seeking professionals who thrive in a dynamic, fast-paced, and highly collaborative environment where problem-solving, critical thinking, and a holistic approach to serving the mission are key. Our program operates within the Scaled Agile Framework (SAFe). An aptitude and enthusiasm for continuous learning, improvement, and cyber security is a must!

ECS is looking for a Software Developer to support the development of an integrated solution to visualize cyber security related data. This position will work as part of an agile development team to conduct systems design, analysis, and development of the solution.

Successful candidates will have demonstrated experience writing well-structured Python code using best practices to deliver enterprise-level applications. Candidates should have a solid understanding of core data pipeline processing capabilities to include different design patterns, stream vs bulk processing, ETL functionality, a range of data stores, and APIs. The ability to develop and deliver reliable, performant, and scalable solutions on time is a critical ability of the ideal candidate.
