Frontend Engineer

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 organizations 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 You will build frontend systems for secure compute, governed data, and operational workflows running in high-trust environments. You will work across product, engineering, and customer teams to design and ship interfaces for governance systems, runtime environments, orchestration workflows, and controlled execution environments. You will contribute to scalable frontend architecture, reusable operational feature systems, shared platform primitives, and composable application patterns across both control plane and runtime domains. We are evolving the frontend platform toward independently deployable and composable application architecture, with shared interaction systems, reusable workflows, and clear ownership boundaries across the platform.
