We are a data-driven company with a collegial atmosphere looking for team members who can do great work for application in the algorithmic trading industry. NumerixS Quant builds quantitative trading strategies grounded in science and driven by technology. With a team of scientists, mathematicians, and physicists, we design and run systematic trading strategies grounded in rigorous academic research. We are seeking a Controller who will be solely responsible for the accounting function and PNL reconciliation, serving as a financial business partner to leadership. Our ideal candidate is a hands-on, independent accounting professional with hedge fund experience who quickly builds strong working relationships with stakeholders. This opportunity will be remote, based in Texas. About you You've built a career in hedge fund or alternative investment accounting, have owned the full accounting cycle, and you're ready to take that ownership to the next level as a solo operator. You're motivated by running the whole function and taking full accountability for its accuracy, integrity, and controls, not just executing within it. You’re self-directed and think like an owner: anticipating issues before they surface, setting the processes others will follow, and being the final word on the numbers. What You’ll Do Full ownership of the accounting function, including books, records, and internal controls, maintained in Xero. - Own the monthly PNL reconciliation process with investors, confidently identifying and resolving discrepancies to ensure the firm’s numbers are accurate and well-supported. If the numbers don’t line up, you’re the one who digs in, makes the case, and doesn’t back down until it’s resolved correctly. - Build strong, trust-based relationships with clients and stakeholders, to quickly and efficiently resolve discrepancies. - Review and approve all supplier invoices, with an eye toward cost control and ensuring the firm is never overpaying for expenses, resolving discrepancies if they arise. - Manage payroll across the US and Canada using ADP, accurately and on schedule. - Ensuring the accounting books, records and related internal controls are appropriate for audit. - Design, document, and maintain accounting policies and internal controls appropriate for the company’s size and regulatory environment. - Own everything that touches money, including managing bank accounts, all ad hoc banking tasks, transfers, and money-related HR tasks. What You Bring - 7+ years of accounting experience, including prior experience owning a full accounting function inside a hedge fund or alternative investment fund. - Hands-on general ledger ownership, running books independently without oversight. - Experience reconciling internal PNL to an external party’s calculation. - Demonstrated ability to identify and resolve discrepancies with confidence, including experience advocating for a position with an external party and supporting it with clear, accurate data. - Strong interpersonal and relationship-building skills, with the ability to maintain productive working relationships even in the context of firm, direct communication. - Proficiency or fast ability to ramp on Xero and ADP for both US and Canada payroll. - Comfortable being the sole finance person in the building — no backup, no team to lean on. What We Offer - Annual bonus eligibility based on performance - Extended healthcare coverage - 401(k) matching up to 9% (maximum annual contribution of $13,250)*
