Senior Manager, Strategic Finance

Nelo•New York, NY

About The Position

Nelo is a leading fintech in Mexico reimagining credit to expand consumer buying power through credit cards, BNPL loans, bill payments, and our own marketplace. With over $80M USD in annual revenue and $140M+ raised in equity and debt, we are on a mission to transform the way consumers use credit in the region. Our lean and technical team includes alumni from Uber, Rappi, DiDi, and Amazon, operating across Mexico City and New York. We move fast, think deeply, and hold a high bar for execution. We are looking for people who thrive in that environment. We are looking for a Strategic Finance (Senior) Manager to own Nelo's financial modeling engine. This is the core quantitative role within Strategic Finance: you will be responsible for the company model, all scenario planning, and the tooling that helps leadership and operators understand where growth is headed, how revenue is tracking, and what the business looks like under different assumptions. Approximately 50-60% of your time will be spent modeling. The rest will be spent translating model outputs into clear, decision-ready communication for founders, board, and senior management. This role is instrumental to the Company’s storytelling and is core to the creation of board decks and corporate presentations, with extensive exposure to C-level executives and investors. This is not a reporting role. You will own the underlying assumptions and input variables, monitor them in near real time, and update the model as the business evolves. You will know why every line moves before anyone asks.

Requirements

5 or more years in a data, finance, or quantitative role at a fintech or tech company

Strong Python skills: you use it for data manipulation, model automation, and dashboard tooling
Comfortable writing and debugging SQL for data pulls from a warehouse (Athena, BigQuery, or similar)
You use AI actively in your workflow, not as an afterthought
You work with speed and precision; attention to detail is not a trade-off for you
You communicate outcomes clearly to non-technical audiences, in writing and in person
You are a strong storyteller: you can take a complex model and turn it into a clear, compelling narrative that drives decisions
You produce clean, precise charts and visualizations; you know which chart type fits which insight and you design for the audience, not for yourself
