## 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

We are looking for an experienced Senior MLOps / LLMOps Engineer to lead the deployment, monitoring, orchestration, and operational reliability of our production LLM applications and agentic AI platform. In this role, you will bridge the gap between AI development and production infrastructure, ensuring multi-step agentic workflows, data pipelines, and retrieval-augmented systems run reliably, securely, and at scale within a large-scale Kubernetes environment. What you’ll do: Design, deploy, and manage LLM services, agentic applications, and supporting AI workloads inside high-throughput Kubernetes clusters. Automate containerized deployments, scalable inference endpoints, and blue/green or canary rollout strategies for LLM/Agent releases via modern CI/CD pipelines. Support and maintain the production operation of agentic AI workflows, including multi-step tool execution, state management, and multi-agent coordination. Rapidly triage and resolve issues across AI application logic, orchestration frameworks, external API integrations, and underlying cloud infrastructure. Build end-to-end monitoring and evaluation (Eval) frameworks to measure and maintain AI output accuracy, drift, latency, cost, and hallucination metrics. Implement trace-level observability for agent execution paths (tracking prompts, completions, tool calls, and agent steps). Monitor and optimize real-time and batch data pipelines powering AI workloads, including feature stores, vector indexing, and embedding updates. Manage resource allocation (GPU/CPU utilization), memory footprint, autoscaling strategies, and cloud infrastructure expenditure to optimize time-to-first-token (TTFT) and throughput. What we are looking for: 3+ years of experience in MLOps, LLMOps, Platform Engineering, AI Infrastructure, or SRE with a focus on machine learning workloads. Hands-on experience managing and deploying complex containerized applications on Kubernetes (EKS, GKE, AKS, or bare metal) at scale. Strong proficiency in Python for backend automation, system debugging, custom tooling, and integration development. Proven experience with standard monitoring/logging tools (e.g., Prometheus, Grafana, Datadog, OpenTelemetry) as well as LLM-specific tracing and evaluation platforms (e.g., LangSmith, Phoenix/Arize, Langfuse, TruLens). Familiarity with modern CI/CD pipelines (GitHub Actions, GitLab CI, ArgoCD) and Infrastructure as Code (IaC) tools (Terraform, Pulumi). Deep operational understanding of agentic architectures, prompt chaining, function calling/tool execution, and non-deterministic application behavior. Nice to have: Practical experience operating Retrieval-Augmented Generation (RAG) pipelines and production vector databases (e.g., Pinecone, Qdrant, Milvus, pgvector, Weaviate). Hands-on exposure to agent development and orchestration frameworks (e.g., LangChain, LangGraph, LlamaIndex, AutoGen, CrewAI). Experience with high-performance LLM serving engines and frameworks (e.g., vLLM, TGI, Ollama, TensorRT-LLM). Understanding of AI security practices (prompt injection mitigation, data privacy, PII masking) and rate limiting/cost guardrails. Benefits:

## About Valarian Technologies Limited

## Company Overview
- **One‑liner**: Valarian builds infrastructure that lets enterprises and governments run AI, agents and applications inside a hardened, governed environment where the customer — not the vendor — holds the keys.
- **Entity Type**: Private (Series A)
- **Headquarters**: London, United Kingdom
- **Founded**: 2020
- **Founders**: Max Buchan (CEO) and Josh McLaughlin (COO) [valarian.com](https://www.valarian.com/about)

## Core Business
- **Primary industries**: National security, defence, regulated enterprise (finance, critical infrastructure)
- **Target customers**: Government / defence organisations and regulated enterprises that require high‑trust, high‑stakes deployment (B2B)
- **Mission / purpose**: “Building the infrastructure to regain control over your high‑consequence systems” — giving customers model independence, auditability and containment without ceding control to a third party [valarian.com](https://www.valarian.com/)

## Products & Services
- **ACRA (Automated Compartmentalised Runtime Architecture)**: A Kubernetes‑native control architecture that extends the cluster with workload‑level governance. Each workload (model, agent, service) runs inside its own enclave with built‑in policy enforcement, default‑deny networking, short‑lived secrets, per‑workload messaging and end‑to‑end audit. ACRA is cloud‑agnostic and can run on AWS, Azure, on‑prem or air‑gapped. [valarian.com](https://www.valarian.com/)

## Market Standing
- **Valuation / Market Cap**: Not disclosed (private company)
- **Key Metric**: **Total Funding – $70M** (Series A of $50M led by New Enterprise Associates, bringing total to $70M) [valarian.com](https://www.valarian.com/)
- **Notable Investors / Partners**: New Enterprise Associates (lead), plus “leading defence and national security investors”; also backed by operators from Palantir, Darktrace and US Special Operations. [valarian.com](https://www.valarian.com/about)
- **Growth Signals**: Deployed across multiple continents; “100s of enclaves deployed”; headcount grew ~18.5% YoY (from 19 to ~24 employees); actively hiring across engineering, compliance and security roles. [linkedin.com](https://linkedin.com/company/valarian)

## Competitive Advantages
- **Customer‑held keys**: Even Valarian cannot access customer systems after deployment — governance is enforced by the infrastructure, not by privileged access. [valarian.com](https://www.valarian.com/)
- **Model‑independent**: Customers can run any model (open‑weight or frontier) without vendor lock‑in and without the model provider training on their data. [valarian.com](https://www.valarian.com/)
- **Built by operators with real‑world experience**: The team includes backgrounds from US Special Operations, Palantir, Darktrace, secure communications and high‑assurance systems, giving them credibility in environments where failure has real consequences. [valarian.com](https://www.valarian.com/about)
- **Air‑gap ready**: ACRA is cloud‑agnostic and can operate in disconnected, air‑gapped environments — a rare capability designed from day one for government/defence deployments. [valarian.com](https://www.valarian.com/)

## Strategic Focus
- **Current priorities**: Scaling the platform for wider enterprise and government adoption; continuing to harden ACRA as the posture layer for AI workloads; expanding the team (engineering, security, compliance) to meet demand from regulated sectors. [jobs.lever.co](https://jobs.lever.co/valarian)
- **Direction for growth**: Maintain “sovereign control” positioning — enabling customers to own their inference, data and access policies regardless of cloud or infrastructure substrate.

## Why Work Here
- **Culture**: Hybrid work setup with a London HQ (flexibility where it matters, structure where it counts). [valarian.com](https://www.valarian.com/careers)
- **Compensation & benefits**: Competitive compensation, equity, and employer‑enhanced pension contributions. [valarian.com](https://www.valarian.com/careers)
- **Engineering environment**: Work on deep infrastructure (Kubernetes, SPIFFE/SPIRE, Cilium, Istio, Vault, NATS, OpenTelemetry) in a high‑trust, high‑impact domain that spans government, defence and regulated enterprise. Engineers are expected to own meaningful pieces of the platform from day one.
- **Notable perks for job seekers**: Opportunity to work on a product that deals with cutting‑edge AI governance and national‑security‑grade isolation; small but growing team (24 people) where contributions are highly visible.
