About The Position

Peregrine Advisors is a firm founded on a simple conviction: the best solutions come from the people closest to the problem, given real ownership and the tools to deliver. We are a data and technology innovation hub and a Benefit Corporation working at the center of the federal government's mission to deliver for client stakeholders and the US public, looking for highly motivated contributors who thrive when trusted to own a hard problem and equipped to deliver the solution. Your first assignment is to own the database layer of a federal agency's enterprise data platform: the physical design, the models, and the performance that let analysts and systems trust it at scale. You will shape how a large, high-volume platform is structured and tuned across Amazon Aurora, DynamoDB, and Apache Iceberg tables on S3. The work is real, hard, and it matters. It is also where you start, not the shape of your career here: we hire people, not seats, and we move our best to where the hardest problems are.

Requirements

• Sole United States citizenship and the ability to obtain a Public Trust determination.
• Hybrid role based in the Washington, DC metropolitan area, requiring regular commuting into DC.
• 7+ years of database development and administration experience.
• Bachelor’s degree.
• Deep, hands-on ownership of a database layer on Amazon Aurora (PostgreSQL-compatible), DynamoDB, and S3 with Apache Iceberg tables: physical design, tuning, and modeling.
• Expertise in stored procedures, schema migration, S3 load patterns into the platform stores, and governed access.
• Judgment to build in a regulated environment where accuracy and auditability are not optional.
• Physical design at scale: partitioning, indexing, and storage layout.
• Query and EXPLAIN-plan tuning on large datasets.
• Logical and physical data modeling.
• PL/pgSQL stored procedures and S3 load patterns into the relational and Iceberg stores.
• Basic proficiency in writing, PowerPoint, and Excel.

Nice To Haves

• Schema migration tooling (AWS Schema Conversion Tool).
• Apache Ranger access controls.
• Neptune or Neo4j.
• Federal information technology or high-volume transaction experience.
• Familiarity with AI-assisted developer tooling.

• Develop the pipes and guardrails around the database layer: schema migrations, S3 load patterns into the relational and Iceberg stores, stored procedures, and Apache Ranger access controls.
• In time, contribute to the firm itself by developing new capabilities, tools, and lines of business.
