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.

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
