FP&A Manager
Allen Control Systems • Austin, TX • Full Time
Posted on Wed, May 6, 2026
Company Overview
Allen Control Systems (ACS) is a cutting-edge defense startup founded by two former Navy electrical engineers with a proven track record in robotics and software. We are developing an autonomous gun turret using advanced computer vision and control systems to precisely detect, track, and neutralize enemy drones.
With an engineering-first culture, ACS values technical excellence and innovation. Backed by our founders’ successful exits from two previous ventures acquired for a combined $180M in 2022, we are committed to ensuring that the groundbreaking technologies we develop will have a real-world impact.
About The Role
We are looking for an FP&A Manager to join our team. ACS is shipping autonomous counter-drone systems to SOCOM, the U.S. Army, and customers across multiple countries, and we are on a clear trajectory to $1B in annual revenue. The FP&A Manager we hire will build the planning and reporting infrastructure that helps us get there. You will own the company’s financial forecasting and budgeting processes, build the board and investor reporting package from scratch, and serve as a direct analytical partner to the CFO. This role starts as a senior individual contributor and will grow into a people management role as ACS scales.
What You’ll Do
Own the company’s annual operating plan and quarterly reforecast process end-to-end; maintain a rolling financial forecast that reflects actual contract award timing, production schedule changes, headcount plans, and capital deployment.
Build scenario models that answer questions such as: what happens to the P&L and balance sheet if a contract is delayed, if production accelerates, or if a new program is awarded mid-year.
Build the monthly and quarterly board reporting package from scratch including financial statements, KPIs, variance analysis, and forward outlook; support the CFO in board preparation, investor diligence, and future fundraising activity.
Build department-level budget accountability: work with functional leaders to set plans, track actuals, and deliver variance commentary that is actionable rather than just descriptive.
Develop the financial reporting cadence that keeps leadership informed without creating reporting overhead.
Hire and develop a small FP&A team over time, building the function to support a business growing rapidly in revenue, headcount, and complexity.
What You’ll Need
Has built FP&A infrastructure from scratch at a high-growth, capital-intensive company; not inherited a mature process, but designed and built one.
Strong financial modeling skills: three-statement modeling, scenario analysis, sensitivity analysis, and the ability to build models that non-finance leaders can use.
Direct experience building board and investor reporting packages; you understand what a sophisticated board wants to see and how to present financials with clarity and narrative.
Comfortable operating in a business with a complex revenue model: government contracts with milestone billing, multiple contract types, and a production schedule that drives the P&L.
Strong written communication and presentation skills; background at a fast-moving, engineering-driven company in defense, aerospace, hardware, or adjacent industries.
Comfortable using AI tools in daily financial modeling and analytical work; we will ask how in the interview.
You’ll Stand Out
Experience supporting a Series B or later fundraise including financial model preparation, data room management, and investor diligence.
Experience implementing or operating a modern FP&A planning tool such as Mosaic, Pigment, or Adaptive Planning.
Familiarity with government contract revenue recognition under ASC 606 and how contract type affects the P&L forecast.
Exposure to defense or aerospace program economics: bookings, backlog, funded vs. unfunded, and how they translate into forward revenue.
Has hired and developed FP&A talent before, even at small scale.
