Valarian: Innovating for the new era of digital sovereignty

Valarian Technologies is a dual-use technology company building critical tools to safeguard the future in an era of evolving global security challenges. We're rethinking security beyond traditional military domains, addressing asymmetric threats that impact our technological advantage, economic strength, and democratic institutions.

We build Acra – the platform foundation for everything we do as a dual-use technology company. The platform’s name, rooted in the Greek word for citadel (or, fortress), reflects the design and purpose of our infrastructure-agnostic secure enclaves: protecting critical data. Some of the government and commercial workflows include: increased operational resiliency for mission-critical systems and functions; enabling organisations to more quickly and widely adopt emerging technologies while ensuring the integrity of their intellectual property; information flow during disaster response scenarios, and zero-trust / least-privilege environments for M&A, attorney-client privileged communications, etc. And we’ve only scratched the surface.

At our core, we're driven by a shared mission and a belief in making a tangible impact on our world. Whether you join our London HQ or the wider global organisation, you’ll be a part of collaborative, high-performing teams, creating cutting-edge software, platforms, and infrastructure.

The Role

We are looking for a hands-on Finance Manager to take ownership of finance operations, month-end accounting and management reporting within a growing, early-stage business.

Reporting to the Head of Finance, you will be responsible for ensuring that the day-to-day finance function runs accurately, consistently and on time. You will own the monthly close through to the production of management accounts, while also managing a broad range of finance, compliance, equity, systems and business-support workstreams.

This is a manager-level individual contributor role rather than a junior support position. You will be expected to independently prioritise work, establish what needs to be done, coordinate internal stakeholders and external advisers, and drive tasks through to completion. You should escalate material risks and decisions, but will not need the Head of Finance to manage each step of your work.

A key part of the role will be utilising modern finance software, integrations and pragmatic automation to operate an effective finance function with a lean team. You will assess where technology can remove repetitive work, improve controls, strengthen data quality and provide better visibility, while avoiding unnecessary complexity or overengineering.

You are not expected to personally provide specialist tax, legal or valuation advice. However, you will be expected to own those processes internally: gathering information, briefing advisers, managing deadlines, reviewing outputs, coordinating approvals and ensuring actions are completed.
