This position requires an active U.S. Government Security Clearance at the TS/SCI level.

We are seeking an experienced Back-End Software Engineer to support the design, development, integration, and sustainment of a large-scale data analytics platform supporting a U.S. Government customer. The successful candidate will develop and maintain scalable, secure, and high-performance server-side applications, services, APIs, and supporting software components that enable data ingestion, processing, integration, and analytics capabilities.

The engineer will work within a multidisciplinary Agile development team, collaborating with data engineers, data scientists, front-end developers, systems engineers, and government stakeholders to deliver reliable, mission-focused software solutions. The role requires strong software engineering fundamentals, experience developing distributed applications, and the ability to contribute throughout the software development lifecycle.

Principal Responsibilities:

Back-End Application Development: Design, develop, test, and maintain scalable server-side applications, services, microservices, and supporting software components.
API and System Integration: Develop and maintain RESTful APIs and service interfaces to facilitate integration between data platforms, applications, databases, and external systems.
Data Platform Enablement: Build software components and services that support data ingestion, processing, querying, access, and analytics across distributed data environments.
Performance, Reliability, and Security: Optimize application performance, troubleshoot complex software issues, and implement appropriate security, authentication, authorization, and error-handling mechanisms.
Agile Development and Collaboration: Participate in technical design reviews, code reviews, automated testing, CI/CD activities, and Agile development ceremonies; collaborate with cross-functional engineering teams to deliver and sustain platform capabilities.

Minimum Qualifications:

Must be a U.S. Citizen with an active TS/SCI clearance (with willingness to obtain a CI poly)
Bachelor's degree in computer science, software engineering, information systems, or related field with 8+ years of total professional experience in a technical support role
Demonstrated experience in software engineering, back-end application development, or a related technical discipline.
Strong proficiency in at least one modern back-end programming language, such as Python, Java, Go, or C#, with demonstrated experience developing production-quality software.
Experience designing and developing RESTful APIs, server-side applications, and distributed software components, with proficiency in relational and/or NoSQL databases.
Willingness to work onsite at least 75% (or as needs dictate) from either Herndon, VA or Westminster, CO.

Preferred Qualifications:

Experience developing microservices and distributed applications using frameworks such as Spring Boot, FastAPI, Flask, .NET, or similar technologies.
Familiarity with big data technologies and distributed processing frameworks such as Apache Spark, Hadoop, Kafka, or Elasticsearch.
Experience with cloud platforms and services, particularly AWS, Microsoft Azure, or Google Cloud Platform.
Familiarity with containerization and orchestration technologies such as Docker and Kubernetes.
Experience with CI/CD pipelines, Git-based version control, automated testing, and DevSecOps practices.
Knowledge of software security principles, secure coding practices, and application security frameworks such as OAuth 2.0 and OpenID Connect.
Experience with Agile/Scrum development methodologies, automated software testing, and infrastructure-as-code tools.
Experience supporting government, defense, intelligence, or other regulated environments.
