About Flox

We’re building Flox to make Nix practical for teams operating at enterprise scale — giving developers and AI agents a reproducible foundation to build and run software without environment drift.

We recently raised a $25M Series B led by Addition, NEA, and D. E. Shaw. We’re still early, but we’re already working with companies including NVIDIA, Microsoft, CoreWeave, Morgan Stanley, D. E. Shaw, Resolve AI, and PostHog.

As we enter our next stage of growth, we’re looking for someone to build the financial and operational backbone of the company alongside our CEO and leadership team.

The Role

We’re hiring a Head of BizOps/Finance. You’ll own our financial model, planning, forecasting, and core finance operations, while also working directly with the CEO on the questions that matter most to the company: where we invest, how quickly we hire, how we price, how we measure the business, and which strategic opportunities we pursue.

We’re looking for someone who likes being close to the details but can zoom out quickly. One day you may be preparing for a Board meeting or updating our operating model; the next you may be evaluating a strategic partnership, acquisition opportunity, major customer investment, or new market initiative.

You’ll have significant ownership from day one and the opportunity to grow into a key member of our leadership team.

What You’ll Own

• Finance and planning: Own our operating model, budget, forecasts, cash planning, runway, and long-range scenarios.

• Company performance: Build the metrics and reporting that help us understand how the business is performing and where we should invest.

• Board and fundraising: Lead the financial side of Board preparation, investor reporting, fundraising, and diligence.

• Corporate development: Evaluate strategic partnerships, acquisitions, investments, and other inorganic opportunities, including financial analysis, diligence, and transaction support.

• Finance operations: Oversee accounting, tax, treasury, compliance, and financial reporting, working with external partners where appropriate.

• GTM economics: Partner with the commercial team on pricing, packaging, revenue forecasting, deal economics, and sales capacity.

• Business operations: Take on important cross-functional problems, improve how we operate, and build the systems and processes we’ll need as the company scales.

Who We’re Looking For

We expect the right person to have roughly 8+ years of experience, but we care more about trajectory and judgment than checking every box.

You may come from IB, PE, strategic finance, corporate development, consulting, or a high-growth technology company. Finance experience is strongly preferred, and experience evaluating strategic transactions, partnerships, or acquisitions is a plus.

You’ll likely be a strong fit if you:

• Are excellent with financial models and comfortable making decisions with imperfect information.

• Understand how venture-backed technology companies operate and what changes as they scale.

• Can evaluate both organic and inorganic growth opportunities, moving comfortably between strategy and execution.

• Have worked closely with founders, executives, Boards, or investors.

• Communicate clearly and can turn complex analysis into a simple point of view.

• Enjoy building from scratch rather than inheriting mature systems and processes.

• Want a role where the scope will evolve as quickly as the company does.

Experience with enterprise software, developer tools, cloud infrastructure, AI infrastructure, or usage-based businesses is helpful but not required.
