Job description

Our Mission

Reflection’s mission is to build open superintelligence and make it accessible to all.

We’re developing open weight models for individuals, agents, enterprises, and even nation states. Our team of AI researchers and company builders come from DeepMind, OpenAI, Google Brain, Meta, Character.AI, Anthropic and beyond.

Role Overview

As Controller, you’ll build the accounting function from the ground up. You own the close, technical accounting, financial reporting, and the internal controls that make all of it trustworthy. You’ll navigate complex deal structures across sovereign and enterprise contracts, manage the external audit relationship, and oversee equity accounting as our programs scale. You’ll own tax compliance and strategy, partner with legal and finance on entity structure, and build the accounting and tax teams beneath you. This role reports to the VP of Finance.

What You’ll Do

• Own the month-end and quarter-end close — accuracy, timeliness, and improving both

• Lead all technical accounting determinations: revenue recognition, equity, leases, and novel deal structures

• Own global tax strategy, planning, and compliance — federal, state, and international

• Manage the external audit relationship end-to-end; own the audit timeline and deliverables

• Build and maintain internal controls and financial reporting infrastructure

• Partner with legal on entity structure and transfer pricing

• Oversee AP, AR, payroll, and treasury operations

• Build the accounting and tax teams beneath you

What We’re Looking For

• 7-10+ years of relevant finance and accounting experience

• CPA required; Big 4 background strongly preferred

• Deep technical accounting expertise — ASC 606, ASC 718, ASC 842, ASC 360 and the judgment to handle what's not in the textbook

• Experience owning a close process and an audit at a high-growth technology company

• Demonstrated ability to build an accounting function from scratch, including team, systems, and processes

• Comfortable navigating ambiguity in deal structures and translating complexity into clear accounting positions

• Strong technical foundation in federal and international tax, with exposure to multi-entity or multinational structures

• International experience, including transfer pricing and cross-border operations

What We Offer:

We believe that to build superintelligence that is truly open, you need to start at the foundation. Joining Reflection means building from the ground up as part of a small talent-dense team. You will help define our future as a company, and help define the frontier 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 the best talent globally.

• Health & wellness: Comprehensive medical, dental, vision, life, and disability insurance.

• Life & family: Fully paid parental leave for all new parents, including adoptive and surrogate journeys. Financial support for family planning.

• Benefits & balance: paid time off when you need it, relocation support, and more perks that optimize your time.

• Opportunities to connect with teammates: lunch and dinner are provided daily. We have regular off-sites and team celebrations.
