Description:

Join a high-impact, mission-driven team as a Full-Stack Software Engineer, supporting a mature and well-established technical organization. You’ll be a member of a small 3-4 person team, which plays a critical role within a broader 20+ person development organization. Together, the team supports a robust web-based platform that integrates diverse publicly available information (PAI) sources into a powerful analytical tool used by hundreds of mission customers.

In this role, you'll contribute across the stack, developing ingest pipelines, building scalable REST APIs, and enhancing user-facing visualizations. The platform supports large-scale data ingestion, complex queries, and interactive analysis. You'll collaborate closely with other sub-teams on the project to ensure end-to-end functionality and performance. We're looking for a developer who is excited to contribute to all aspects of this system and who also brings an interest in improving team processes and tooling, particularly in ways that help us integrate new data sources more efficiently and deliver faster.

This long-running software effort is known for its technical stability, team cohesion, and deep integration into mission-critical systems, offering you the opportunity to make meaningful contributions in a fast-paced, collaborative environment.

• Drive the continual evolution of a mature software system, encompassing code quality, testing, documentation, and Jira ticket management, while leading the end-to-end design and implementation of data processing workflows.
• Leverage established design patterns and AI platforms to streamline code development, data transformation, and schema management, ensuring the product’s long-term scalability and maintainability.
• Understand API-driven microservice design patterns, No
  
  SQL databases, dataflow tools (Apache NiFi), and modern web frameworks.
• Contribute to all parts of the data processing lifecycle, from collection to processing to storage, and facilitate presentation to analysts in our UI.
• Manage and optimize data storage, retrieval, and performance using Elasticsearch and the Dgraph graph database, with some MongoDB and Redis used as well.
• Maintain a team player mentality as a collaborative member of a fast-paced, structured team; and provide mentorship and guidance to team members in best practices for data processing and software engineering.
• Collaborate with analysts, product owners, and fellow engineers to ensure solutions meet operational needs.
• Help identify and implement process improvements to support faster delivery of new data sources and overall team efficiency.
