About Prefect

Prefect builds automation for an unpredictable world. The last decade of automation was about protecting workflows from unpredictability; in the agentic era, unpredictability is the point. Our mission is to give people confidence in automated work, whether that work is a mission-critical data pipeline or a fleet of AI agents.

In August 2026, Prefect and Dagster, competitors for eight years, joined forces to build the next generation of automation infrastructure. Today, our ecosystem includes Dagster, the data platform; Prefect, the agent platform; and FastMCP, the leading open-source developer framework for the MCP ecosystem. Together, our open-source and commercial products are trusted by Fortune 500 companies, data innovators, and high-growth technology companies around the world.

We think of our culture as the operating system of the company. We’ve carefully created a supportive, high-performance environment that empowers our team to do the best work of their careers, have meaningful impact, and continue growing personally and professionally. We’re a remote-first team that values high standards, ownership, and thoughtful collaboration.

Role Summary:

Reporting to Justin, our Senior Director of Finance, you’ll take ownership of operating expense accounting for Prefect. This includes assessing and recording monthly accruals, maintaining the cash feed and ensuring transactions are accurately captured, and overseeing budget vs. actuals, T&E, vendor bill payments, and corporate card programs.

You’ll be the person department leads come to when they want to understand what they’ve spent and what they have left, and the person making sure vendors and employees get paid accurately and on time. It’s a hands-on role with a lot of ownership, cross-functional visibility, and room to make the work you own more efficient as the company grows.

You’ve done this before at a software or tech startup, you’re comfortable being the primary owner of a process rather than one of several hands on it, and you’re comfortable working in a modern finance stack like Ramp, Navan, and Stripe.

What You'll Do:

Own budget vs. actuals reporting, partnering directly with department leads to explain variances and keep them informed of their spend.

Manage the full operating expense cycle: vendor bill payments (AP), the corporate card program, and employee travel & expense reimbursements.

Prepare journal entries, accruals, and balance sheet reconciliations for opex accounts as part of month-end close, consistent with GAAP.

Assist with federal and state reporting requirements and tax filings, including corporate tax returns, sales tax registrations and filings, and 1099s.

Partner with department heads to improve how they track and forecast their own budgets — you're building the process, not just running it.

Identify and drive automation and process improvements across AP, T&E, and close, using tools like Ramp, Navan, and Rillet.

Assist with ad hoc requests and projects, such as system automations, process improvements and researching technical accounting topics.

Your Qualifications:

Must-haves:

3+ years of progressive accounting experience, ideally at a fast-growing software or tech startup.

Hands-on ownership of AP, corporate card programs, and/or T&E processes — not just a supporting role on someone else's.

Experience with modern finance tools like Ramp, Stripe, and Navan.
