Senior Financial Analyst

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 a Senior Financial Analyst to be the day-to-day finance partner to our Engineering and Enablement functions at a company shipping autonomous counter-drone systems to SOCOM, the U.S. Army, and customers across multiple countries, on a clear trajectory to $1B in annual revenue. This is an execution-focused, high-visibility individual contributor role. You will own the budgets, forecasts, and financial reporting for Engineering and enabling functions including IT, Facilities, and People, and work directly with functional leaders to ensure spend, headcount, and program plans are grounded in financial reality. You will also help stand up the tools, templates, and reporting cadence FP&A runs on as the company scales. This role is on-site in Austin, TX.

What You’ll Do

• Build and maintain the annual budget and quarterly re-forecast for Engineering and Enablement cost centers, including headcount, R&D spend, and program-related costs; partner with Engineering leadership to forecast hiring plans, contractor and tooling spend, and program-driven cost changes.

• Own monthly budget-versus-actual variance analysis for supported functions and deliver clear, actionable commentary to functional leaders and FP&A leadership; prepare recurring reporting packages and ad hoc analyses, and contribute inputs to the broader monthly and quarterly finance reporting package.

• Serve as the primary FP&A point of contact for Engineering and Enablement leaders; build financial models and tools that non-finance leaders can use to manage their own budgets; help functional leaders understand the drivers behind variances and translate operational decisions into financial impact.

• Help build and refine the systems, templates, and processes FP&A uses to plan and report; contribute to the evaluation and rollout of a modern FP&A planning platform; take on increasing scope across additional functions as the team and business grow.

What You’ll Need

• 3 to 5 years of progressive FP&A experience, ideally supporting an engineering, R&D, or technical function; strong Excel and financial modeling skills with the ability to build clear, usable models and reports for non-finance stakeholders.

• Comfort working with headcount-heavy, engineering-driven cost structures and translating hiring and program plans into financial forecasts; detail-oriented and able to own a full budget cycle from planning through variance analysis.

• Strong business partnering and communication skills, with the confidence to build trust and influence decision-making across technical (R&D) and non-technical (HR, Finance, Legal) stakeholders. Ability to partner directly with engineering and functional leaders and leverage AI and automation tools to build financial models, improve forecasting accuracy, and accelerate analysis.

You’ll Stand Out

• Experience supporting R&D or engineering cost centers, including capitalized R&D or program-based cost tracking.

• SQL or data tooling experience, including Power BI or similar platforms, to support headcount and spend reporting.

What We Offer

• Competitive salary

• ACS Equity Package

• Health, Dental, Vision Insurance

• Paid Time Off
