Job description

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

Your first assignment is to own the data layer of a federal agency's enterprise data warehouse: 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 on Amazon Redshift and its relational neighbors. 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.

What you'll build

• A warehouse data layer that performs: physical design (distribution and sort keys, workload management), query and plan tuning on large datasets, and data models that hold up.
• The pipes and guardrails around it: schema migrations, S3-to-Redshift load patterns, stored procedures, and Apache Ranger access controls.
• In time, the firm itself: new capabilities, tools, and lines of business you help spin up.

Who you are

You are the person who makes a database fast and keeps it honest, and you take that ownership seriously. You have designed and tuned large warehouses, and you know why the physical model matters. You experiment, fail, learn, and repeat quickly. You would rather own an outcome than be handed a task.

What you bring

• Deep, hands‑on ownership of a data warehouse on Amazon Redshift (and relational databases like PostgreSQL and SQL Server): physical design, tuning, and modeling.
• The craft around it: stored procedures, schema migration, S3-to-Redshift loads, and governed access.
• The judgment to build in a regulated environment where accuracy and auditability are not optional.

What you'll need

U.S. citizenship (this initial engagement may be staffed by U.S. citizens only) and the ability to obtain a Public Trust determination. This is a hybrid role based in the Washington, DC metropolitan area, and it requires commuting into DC regularly. Everything else, the years, the certifications, the specific tools, we ask in the application and get into during the interview.

What we offer

Fully paid medical, dental, and vision; a matched 401(k) with immediate vesting; unlimited paid time off; and sponsored certifications. Beyond that, work worth your best years.

What we commit to

As a Benefit Corporation, our commitment runs three ways: real, measurable value for our clients; government that works better for the public; and a team that makes everyone in it better.

We hire people who want to help build the firm, not just work at it. If that is you, apply.

Peregrine Advisors is an equal opportunity employer.
