Strategic Finance Manager

Role Overview

As a Strategic Finance Manager, you'll help build the core muscles of our capital allocation, forecasting, and planning processes. You'll work across the business - spanning GTM, compute, R&D, and corporate finance - building models and analyses that inform how we allocate resources, evaluate opportunities, and plan for growth. The work will vary depending on where you focus, but the common thread is connecting ground-level business activity to rigorous financial thinking.

What You'll Do

• Build financial models across a range of contexts - deals and partnerships, product and channel economics, cost structures, and investment decisions
• Support the corporate financial model with bottoms-up inputs, and maintain that connection as the underlying business evolves
• Partner cross-functionally - with sales, GTM, engineering, research, and finance leadership - to translate business activity into financial frameworks
• Develop cost and investment models (compute, infrastructure, headcount, R&D) to inform resource planning and tradeoff decisions
• Identify financial risks and opportunities early, and help structure decisions that balance growth with returns
• Improve the templates, assumptions libraries, and processes used across the team

What We're Looking For

• 5+ years of experience in strategic finance or FP&A at a high-growth technology company, management consulting, investment banking, or similar
• Strong financial modeling skills - build clean, auditable models from scratch
• Experience with deal economics, revenue modeling, or commercial finance at a technology company
• Comfort with cost-side modeling: you understand how compute, headcount, and infrastructure costs behave
• Ability to work cross-functionally with sales, GTM, engineering, research, and finance leadership without losing rigor
• Comfortable with ambiguity: takes initiative, operates independently, and brings structure and curiosity to open-ended problems.

What We Offer

• We believe that to make intelligence open and accessible to all, you need to start at the foundation.
• Joining Reflection means building from the ground up as part of a talent-dense team.
• You will help define our future as a company, and help define the future of open foundational models.

We want you to do the most impactful work of your career with the confidence that you and the people you care about most are supported.

• Top-tier compensation: Salary and equity structured to recognize and retain our talent globally.
• Stock options: Everyone who joins and contributes to Reflection's success gets to share in the upside through stock options.
• Health & wellness: Comprehensive medical, dental, vision, and life, with an annual wellness allowance.
• Meals: Lunch and dinner are provided in the office daily.
• Life & family: 22 weeks paid parental leave for all new birthing and non-birthing parents, including adoptive and surrogate journeys.
• Vacation days: Unlimited paid time off in the U.S. and 30 days in the U.K.
• Sponsorship support: We sponsor visas to help exceptional talent join our team and support long-term immigration pathways where applicable.
• Team building: We have regular off-sites, happy hours, and team celebrations.
