## 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

You will make the data services and processing workloads supporting ACRA and Valarie reproducible to deploy, observable in production and safe to recover. You will work closely with data engineers and ACRA platform engineers across customer-controlled environments. What you’ll do: Build and maintain CI/CD and GitOps workflows for data applications, pipelines, configuration and database changes, including validation, promotion and rollback. Develop reusable tooling for scheduling, dependency management, retries, checkpoints, replay and backfills. Establish monitoring and actionable alerts for pipeline freshness, completeness, processing latency, failures and resource usage. Operate workload-owned data services and coordinate with ACRA platform owners for shared database, messaging and storage services. Implement and exercise recovery procedures, including backup restoration, interrupted processing and failed upgrades. Integrate data workloads with ACRA’s identity, secrets and network controls, preserving enclave isolation and authorised access. Investigate production incidents, improve runbooks and automate recurring operational work. What you’ll bring:

Valarian Technologies Limited is an equal opportunity employer and welcomes applications from invdividuals regardless of race, colour, religion, sex, sexual orientation, gender, identity or expression, national origin, age, disability, genetic information, marital status, veteran, amnesty, or any other legally protected characteristic.

We are committed to ensuring a fair and inclusive recruitment process and providing employment opportunities to all applicants. Decision recruitment, hiring, and employment are based solely on qualifications, skills, and experience relevant to the job requirements.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analysing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgement. Final hiring decisions are ultimately made by humans.

## 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.
