Finance Finance Manager Los Angeles, CA

Promentrs is a professional services firm providing high-caliber accounting and finance expertise to businesses across industries. We embed experienced professionals directly with our clients, giving them the senior-level talent they need, exactly when they need it. Whether a client is navigating a complex close, managing rapid growth, or preparing for an audit, our people step in and deliver with confidence and precision.

We’re building a team of sharp, self‑motivated accounting professionals who want variety, autonomy, and real impact without the constraints of a traditional in‑house role. This engagement begins as a 1099 independent contractor arrangement, with the option to transition to full‑time employment.

Each engagement is unique. Rather than the routine, maintenance‑driven work that defines most internal accounting roles, you’ll be brought in for purposeful, high‑impact projects that challenge you to think critically and perform at your best. Because you work on one engagement at a time on a full‑time basis, you’re fully immersed in each client’s environment, developing deep expertise across industries, systems, and business situations that most accountants never encounter in a traditional role.

As a Finance Manager at Promentrs, you are the analytical engine behind our clients’ most important financial decisions. Where an Accounting Manager owns the close and the Controller owns the ledger, you own the story the numbers are telling. You will translate financial data into insight, build the models that drive planning, and serve as a trusted business partner to client leadership across functions.

Each engagement is unique. You will be brought in for purposeful, high‑impact work, not routine maintenance. You will work on one engagement at a time on a full‑time basis, immersing yourself fully in each client’s business, industry, and financial challenges. That depth and variety will accelerate your career in ways that a single in‑house role simply cannot match.
