FP&A Manager

Company Overview
ACS (Allen Control Systems) is a defense technology company building precision robotic systems for the United States and its allies. Founded by two former U.S. Navy electrical engineers with deep experience in robotics and software, ACS brings together AI, computer vision, precision motion, and advanced hardware to solve complex defense challenges across land, air, and maritime environments.

Our flagship product, Bullfrog, is an autonomous precision weapon system that transforms existing weapons into highly accurate counter-drone systems — giving warfighters a scalable, cost-effective response to one of the fastest-growing threats on the modern battlefield. Bullfrog is deployed with U.S. forces, and ACS works with organizations throughout the U.S. military and national security community.

Following a $200 million Series B at a $2.2 billion valuation, ACS is rapidly expanding manufacturing, accelerating Bullfrog deployments, and developing the next generation of autonomous battlefield systems. This is an opportunity to join a proven, fast-moving team and help scale technology with direct, real-world impact on national security.

ACS is headquartered in Austin, Texas, with additional operations in Alexandria, Virginia; Mountain View, California; and Huntsville, Alabama. For more information, visit allencontrolsystems.com.

About The Role

We are looking for an FP&A Manager to build and run the FP&A function at a company in production, shipping autonomous counter-drone systems to SOCOM, the U.S. Army, and customers across multiple countries, and on a clear trajectory to $1B in annual revenue. This is a strategic leadership role and a build role. You will own the company’s financial planning and reporting infrastructure, partner directly with the VP of FP&A on capital strategy and KPI development, and provide insights to business leaders across a complex government contract revenue model. The right candidate has led FP&A at a high-growth, capital-intensive company and is ready to do it at greater scale in a business where the numbers matter and the mission is real. This role is on-site in Austin, TX.

What You’ll Do

• Support the annual operating plan, quarterly re-forecast, and long-range financial plan (3 to 5 years) reflecting program ramps, capital deployment, and capacity expansion; maintain and update the rolling financial forecast as contract award timing, production schedules, headcount plans, and capital deployment evolve.

• Build scenario and sensitivity analyses on key business questions including program delays, production acceleration, mid-year awards, and capital structure changes; prepare components of the monthly and quarterly board and investor reporting package, including financial statements, KPIs, variance analysis, and forward outlook.

• Own monthly close-to-forecast variance analysis and translate results into clear, actionable commentary for finance leadership and functional partners; support cash forecasting in partnership with Treasury and the Controller’s team.

• Partner with functional leaders across Manufacturing, Government Contracts, and Operations to build and maintain departmental budgets; help design and implement the systems, templates, and operating cadence the FP&A function will run on as it scales, with the opportunity to mentor or manage analysts over time.

What You’ll Need

• 5+ years of progressive FP&A experience, ideally at a high-growth, capital-intensive company; strong financial modeling fundamentals including three-statement modeling, forecasting, and scenario and sensitivity analysis.

• Comfort operating in a business with a complex revenue model including government contracts with milestone billing, multiple contract types, and a production schedule that drives the P&L; experience supporting board or investor reporting.

• Strong business partnering and written communication skills, with the ability to build trust and influence decision-making across technical (R&D) and non-technical (HR, Finance, Legal) stakeholders. Ability to present financial information clearly to non-finance stakeholders and leverage AI and automation tools to build financial models, improve forecasting accuracy, and accelerate analysis.

You’ll Stand Out

• Experience with NetSuite and modern FP&A planning platforms, with a focus on financial planning, budgeting, and forecasting.

• Exposure to defense or aerospace program economics including bookings, backlog, and funded versus unfunded backlog, and how they translate into forward revenue.

• Experience in a business with significant hardware inventory and a production-driven revenue model; background at a fast-moving, engineering-driven company in defense, aerospace, hardware, or adjacent industries.

What We Offer

• Competitive salary

• ACS Equity Package

• Health, Dental, Vision Insurance

• Paid Time Off
