Job description

About Behavox

Behavox is a cloud-native AI company providing an integrated controls platform for global banks, asset managers, hedge funds, private equity firms, insurance businesses, and commodity firms. The platform unifies communications and trade surveillance, compliant archiving, policy management as well as front-office analytics on a single, AI-native technology stack, delivered as a globally scalable SaaS-based cloud service.

At Behavox, our engineering culture is built around speed, experimentation, and technical excellence, following agile principles and rapid iteration. We constantly test and adopt the latest cloud technologies and AI tooling, optimising for fast feedback loops and execution. We look for people who can move fast, challenge conventional wisdom, and who want to work at the frontier of modern AI, SaaS platforms, and distributed systems.

Behavox is a high-performance organisation with a strong bias toward delivery, ownership, and responsibility. We commit, and we execute. We are building systems that are complex, mission-critical, and global in scale; systems that many consider too large or too difficult. To do that, we seek the smartest, most technically capable engineers and technologists who take end-to-end responsibility and want to win by building what others cannot.

Founded in 2014 and backed by SoftBank Vision Fund, Behavox is headquartered in London, with offices worldwide, including New York City, Montreal, Seattle, Singapore, and Tokyo.

About the Role

The Senior FP&A Analyst owns Behavox's core financial model — its architecture, the accounting beneath it, and the forecasts and analysis the company plans and decides by. The role exists to change decisions, not report them: it turns the numbers into the choices leadership actually faces. It reads and integrates budgets into the model, but does not run the budgeting cycle.

The same analyst builds the valuations, scenarios, and pro-forma models behind every acquisition — evaluating targets, running diligence, and folding closed deals into a single consolidated view. This work is periodic and must be carried alone when it arrives; the steady state is the operating model and SaaS forecasting.

This is a high-autonomy role that works without a detailed brief and sets the modeling standard others build on. It is accountable for the accuracy and integrity of the numbers, and for turning them into recommendations sharp enough to act on — the downside case included, not just the point estimate — for senior leadership, the board, and investors. It pressure-tests the assumptions behind every result, works fluently with modern tooling and AI, and compounds that edge by learning relentlessly. Its influence comes from the rigor and reach of the analysis, not from authority: it owns the model and the truth it tells, not the decisions made from it.

What You'll Bring

1. Financial Model & Accounting Foundations — Knows how an integrated three-statement and operating model fits together, and the accounting that holds it up — SaaS revenue recognition and cost treatment included. Understands exactly how the company's budgets are built, and folds them into the model.
2. Forecasting & SaaS Unit Economics — Knows both bottom-up short-term forecasting and driver-based long-term modeling, and the SaaS metrics that actually reveal performance. Knows what moves each one and which lever changes it — not just how to report it.
3. Mergers, Acquisitions & Integration — Knows how to value an acquisition and how to fold it into one consolidated model: purchase accounting, combined-entity projections, and the mechanics that make or break the integration.
4. Business & Commercial Acumen — Knows in depth how the business and every function make money — the revenue drivers, the cost structure, the operating levers — and spots a number that doesn't add up on sight.
5. Financial Systems & AI Tooling — Commands Google Sheets and Excel, and tracks the AI and automation landscape closely enough to know where it is trustworthy and where it isn't.
