Your first assignment is to help modernize how a federal regulator validates the financial data it receives in eXtensible Business Reporting Language (XBRL), on what may be one of the largest XBRL implementations in existence. You will work in Arelle, the open-source XBRL engine, extending it with the plugins, validation rules, and pipelines that turn incoming filings into validated, trusted data. 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

• Arelle plugins and extensions, built on its plugin architecture and application programming interfaces (APIs), that add and enforce the validation rules a federal filing program depends on.
• Validation pipelines across the full XBRL stack: taxonomies and linkbases, Inline XBRL (iXBRL), Formula, and the Open Information Model (OIM).
• In time, the firm itself: new capabilities, tools, and lines of business you help spin up.

Who you are

You are a strong software engineer first, and you go deep. You have built and shipped real systems in Python, and you master a hard domain rather than skirting it. You experiment, fail, learn, and repeat quickly. You would rather own an outcome than be handed a task.
What you bring

• Senior-level software engineering with strong Python, including building against plugin architectures and APIs.
• Deep XBRL, or the engineering talent and drive to get there fast, across the specification stack, taxonomy work, and validation.
• 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.

[Salary range: TBD]
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.
