Data Scientist

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 will likely include turning a federal agency's operational and filing data into evidence by:

• framing analytical questions with the people who own the mission, and turning them into designs that can actually be tested;
• building analyses and models in Python and SQL against a cloud-native data platform:
  Amazon Aurora (PostgreSQL-compatible), Amazon Simple Storage Service (S3) with Apache Iceberg tables, and related Amazon Web Services (AWS) analytics services;
• designing the evaluation that provides the evidence a model is fit for a regulated environment: baselines, error analysis, and documented limits;
• hardening one-off notebooks into repeatable, reviewed analytical pipelines; or
• putting findings in front of decision-makers in plain language, with visuals that carry the argument instead of decorating it.

Adaptability and a demonstrated capacity to learn new concepts, systems, and tools are what keep you ahead of program needs as projects complete and priorities shift.

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.

• Models that earn their place: forecasting, classification, risk scoring, and anomaly detection matched to the question, the data, and the scrutiny a federal decision has to survive.
• The evaluation evidence behind them: validation designs, error analyses, and documentation that let someone else check the work.
• Analytical features and datasets drawn from large, messy, document-heavy corpora, including text extracted with Amazon Textract and analyzed with foundation models through Amazon Bedrock.
• AI-assisted analysis as standard practice: language models and coding assistants across the lifecycle, with your judgment on top.
• In time, the firm itself: new capabilities, tools, and lines of business you help spin up.

You are rigorous about method and honest about uncertainty: when the evidence supports a narrower claim, you make the narrower claim. You care what the data is for, not just what it contains, and you would rather spend a day understanding the process that produced a number than a week modeling it wrong. You communicate clearly, adapt across roles and clients, and care about creating public value.

You experiment, fail, learn, and repeat quickly. You would rather own an outcome than be handed a task.

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.

A high-performing team of developers, engineers, data scientists, architects, and strategists solving complex, real-world problems, with work that runs from strategy formulation to hands‑on implementation. We develop people across roles and clients, with extensive onboarding and sponsored training and professional development. And Peregrine has been a Benefit Corporation from day one: public value is built into the work itself, not bolted on afterward.

Work worth your best years.

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.

Peregrine Advisors is an equal opportunity employer.
