UX Engineer/Front-End 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.

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.

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. We’re looking for engineers who are comfortable contributing across product decisions, frontend architecture, platform evolution, and user experience.

• Help evolve frontend architecture for composable and independently deployable applications
• Build and ship frontend features end-to-end
• Build well-tested, production-grade frontend systems
• Contribute to product and UX decisions across the platform
• Design interfaces for complex operational and data workflows
• Develop scalable Vue/React + TypeScript applications and reusable component systems
• Write high-quality code that can be easily understood and leveraged by others

Strong experience building and shipping production Vue/React + TypeScript applications. Strong understanding of frontend architecture, state management, and API integration. Good product and UX instincts with attention to usability and performance. Experience building reusable UI systems or component libraries. Experience designing composable frontend systems, reusable workflows, or modular application architectures. Experience with real-time or data-heavy applications.

We are committed to consistently enhancing our benefit package, taking into account the overall well-being and needs of our teammates:

• Equity – because you have the right to own what you’re building
• A competitive salary – because we value your unique skills
• Employer pension contributions – because you deserve a secure future
• Hybrid work setup – because everyone has different needs
• Rewarding company retreats and meetups that respect your work/life balance – because we love getting to know each other!

If you want to join us in the London office – it’s quite nice! – and if you’d prefer to work remotely, that’s fine too.
