Job description

Valarian: A New Era of Sovereign Intelligence

Valarian is a dual use technology company building critical tools to safeguard the future in an era of evolving global security challenges. Backed by a Series A funding round of $50m led by NEA, we are rethinking security beyond traditional military domains to address asymmetric threats that impact our technological advantage, economic strength, and democratic institutions. We provide the control infrastructure that allows government and regulated enterprise to put frontier-class AI to work safely.

We are bringing a frontier AI experience inside secure boundaries for the first time. Our technology supports mission critical workflows across government, healthcare, and enterprise, including:

• Scaling open-weight models without external inference endpoints.

• Putting frontier class AI to work across organisations through partnerships with other leading AI startups such as Perplexity.

• Increasing operational resiliency for air gapped, on prem, and cloud based systems.

• Securing intellectual property and maintaining auditability for high stakes enterprise environments.

• Facilitating secure information flow during disaster response, M&A due diligence, and privileged legal communications.

We’ve only scratched the surface. Built in Britain by veterans of the Ministry of Defence, British Forces, Darktrace, and elite engineering backgrounds, we are driven by a shared mission to safeguard western democracy. Whether you join our London HQ or our wider global organisation, you’ll be part of a collaborative, high performing team creating the cutting edge software and infrastructure that defines the frontier of enterprise AI.

The Role

As a Solutions Engineer, you will deploy, extend, and integrate our secure Kubernetes platform (ACRA) into real-world workflows. You aren't just writing backend services in Go—you are partnering directly with end-users to understand their operational constraints, adapting our containerized workloads to their infrastructure, and feeding crucial feedback back into the core platform team.

You will write production Go, build React frontend components, configure microservices, and orchestrate Kubernetes workloads while collaborating across frontend, core backend, infrastructure, and AI teams to deliver client outcomes.

What you’ll do:

• Deploy & Integrate: Build backend microservices, APIs, and Custom Resource Definitions (CRDs) in Go to integrate ACRA into diverse customer environments (isolated enclaves, edge clusters, hybrid cloud)
• Bridge Product & Customer: Translate ambiguous client security requirements and user workflows into practical technical implementations without waiting for detailed specs
• Kubernetes Application Development: Develop containerized applications, Helm charts, and event-driven microservices running seamlessly on customer K8s platforms
• Collaborate with Specialists: Partner with embedded DevOps/Infra specialists (for base cluster provisioning) and ML/AI engineers (for model harness integration), keeping client value at the center
• Close the Feedback Loop: Identify recurring integration patterns and work with core engineering to turn custom client fixes into standardized platform features

What we are looking for:

• Go & Backend Engineering: Strong hands-on experience building microservices, REST/gRPC APIs, or event-driven backend systems in Go.
• Kubernetes Application Logic & Tech Stack: Deep familiarity with Docker, K8s manifests, Helm charts, GitOps workflows (Argo/Flux), relational databases (RDBs), KV Caches, and Event Buses, focusing on building applications for Kubernetes.
• Product & Customer Intuition: Demonstrated experience interfacing with external clients, solutions architects, or cross-functional teams to solve real operational problems.
• System Design & Security Boundaries: Clear understanding of workload isolation, secrets management, identity-aware communication, and failure domain boundaries.
• Pragmatic Ownership: Comfort operating in ambiguous, fast-moving environments where debugging spans client applications, networking layers, and platform code.

Benefits:

• 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
• Private health insurance - because your health is important to us
• Hybrid work setup – because everyone has different needs
• Gym memberships - because staying active fuels productivity
• Rewarding company retreats and meetups that respect your work/life balance – because we love getting to know each other
