Financial Controller / Finance Partner / Project Manager in Finance

About the role

We're looking for a Financial Controller / Finance Partner / Project Manager in Finance to lead Atomic's highest-priority financial cross-functional projects, starting with our expansion into Europe, and help ensure the integrity of Atomic's books and financial operations across a growing number of entities and product lines.

You'll report directly to the CFO, and to the Financial and Operations Principal (FinOp) on broker-dealer work, and coordinate with leadership across finance, compliance, legal, and operations. As our financial controller, you'll help manage company-wide finance projects while building finance processes in some areas and strengthening them in others. In your first year, you'll also back up treasury, support risk and controls work, and support tax reporting as we quickly ramp up and build out processes and teams covering those areas.

Atomic is a remote-first company, and this role is fully remote; however, candidates must be based in the US or LATAM in the Americas Timezone (GMT-4 to GMT-8).

Key Responsibilities

• Propose, design, and implement projects to shorten and improve the month-end close process, using NetSuite and other systems. Move work into pre-close activities throughout the month, and leverage automated functionality available within existing systems, to immediately shorten the close.
• Take on core controllership responsibilities based on your experience, such as owning the accounting books for the technology and RIA entities, running the consolidated month-end close, or overseeing corporate tax compliance with the FinOp and external tax advisors.
• Enhance and develop consolidated accounting policies and controls appropriate for a fintech environment, across existing and new products and entities.
• Prepare the company for a consolidated audit in 12-24 months.
• Back up the CFO on treasury: cash positioning, payment approvals, bank relationships, and the cash runway forecast.
• Build the finance project management function as the initial hire, including intake, prioritization, templates, and status reporting standards. Maintain a company-wide view of finance project timelines, dependencies, risks, and resource needs, and escalate issues early.
• Lead major cross-functional projects through completion, including Atomic's expansion into Europe, managing workstreams, owners, timelines, and requests from regulators and outside counsel.
• Plan and run additional projects across finance, compliance, legal, and operations, from scoping through delivery.
• Prepare clear status updates for leadership and run effective project meetings.
• Partner with key stakeholders across finance, compliance, legal, operations, and engineering leadership.

Qualifications

• 3-5 years of project management experience leading cross-functional projects, with a track record of delivering complex initiatives on scope and on time
• Experience managing regulatory, licensing, or market expansion projects in financial services
• Proficiency with project management tools (e.g., Jira, Asana, monday.com or similar)
• Meaningful finance and accounting experience in fintech, banking, brokerage, or RIA environments
• Comfort navigating regulated multi-entity structures, including international subsidiaries
• Working knowledge of US corporate tax compliance and experience working with external tax advisors
• Hands-on treasury and cash management experience, and a working understanding of internal controls
• Basic knowledge of IFRS, sufficient to supervise EU-based accountants
• Proficiency in NetSuite or comparable enterprise ERP systems
• Advanced-level English for cross-team collaboration

Nice to Have

• PMP, CAPM, or similar project management certification
• Active CPA license and/or self-regulatory agency licenses (ex FINRA). CPA will be needed by March 2028.
• Subject-matter expertise in SOX frameworks
• International tax experience, especially with EU-US holding structures
