Head of Financial Systems at Metrea · Katori

Company Overview

Metrea delivers effects-as-a-service to national security partners across five domains and more than a dozen mission areas. These include airborne ISR, electronic warfare, secure communications, aerial refueling, special air missions, aerial firefighting, and advanced simulation. We own the whole stack: designing, building, and operating turnkey capabilities that give our partners decisive, asymmetric advantage against rapidly evolving threats.

Our operating model is built around three interlocking pillars. The Support Groups provide a global shared-service – spanning people, finance, platform, operations, legal, and engagement. This frees up our Core Groups, who develop and own mission capabilities end-to-end, to focus entirely on delivery. The Market Groups apply a regional lens, ensuring that our agile and adaptable capabilities remain aligned to the wicked problems that matter most to our partners across the Americas, EMEA, and Asia-Pacific.

At the heart of our model is a simple but powerful idea: be a true partner with skin in the game. Our partners need effects, not just equipment. By owning the full stack – from the lab to the field – we are able to drive a continuous cycle of innovation that keeps our partners ahead. It's a fast-moving, intellectually demanding environment where talented people are given real responsibility, work on problems that matter, and contribute to an enterprise that is growing quickly and deliberately.

Headquartered in Washington, DC, with facilities across the United States, the United Kingdom, as well as Continental Europe and Asia-Pacific.

Position Summary

The Head of Financial Systems will be a results-oriented and technologically driven financial leader responsible for enhancing Metrea's finance processes, systems, data and reporting capabilities as the enterprise scales globally. A core focus will be identifying and delivering AI-driven efficiency, automation and process improvement across Finance, reducing manual activity, strengthening controls and improving the speed, accuracy and quality of financial reporting. The job governs and maintains financial and operational systems so they remain effective, integrated and fit for purpose, and gives Controlling, Treasury and FP&A the reliable data, tools and processes they need. Working closely with Finance and Platform Technology, the Head of Financial Systems will identify where to simplify, automate and improve reporting and analytics, and will lead financial due diligence in partnership with the Investment function and the post-acquisition integration of finance systems and processes.

The Head of Financial Systems will bring deep finance and operational expertise, real technological fluency and the ability to lead transformation in a complex, fast-scaling global enterprise. Experience in a regulated, government-contracting or aerospace and defence environment is an advantage.

Our Firmware

At Metrea, our single core value is Rooted in Humility, and our four cornerstone attributes are Entrepreneurial, Systematic, Discerning, and Over-Deliver. These form what we call our Teammate Firmware. Just like technical firmware connects software and hardware, our Firmware is the constant interface between our mission and our people. It defines how we show up, how we work together, and how we solve complex problems.

Our team Firmware creates a web-like, hyper-collaborative, dynamically hierarchical way of working that helps us adapt quickly, communicate openly, and distribute decision-making to where expertise actually lives. It enables groups to self-organize around hard problems, shift fluidly as priorities evolve, and operate with the trust, curiosity, and discipline required in a complex mission space. This foundation allows us to deliver elegant, effective solutions and uphold our purpose: protecting our precious inheritance.
