We're rethinking security beyond traditional military domains, addressing asymmetric threats that impact our technological advantage, economic strength, and democratic institutions.\nWe 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 organisations 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.\nAt 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.\nThe Role\nWe are looking for a Senior Customer Deployment Engineer to lead the installation, upgrade, and operational delivery of ACRA in customer environments.\nYou will work directly with customers, onsite and remotely, to understand their requirements, prepare their infrastructure, install ACRA through our Onboarding Wizard, and guide deployments through validation and operational handover. You will also help maintain live deployments, deliver upgrades, and work with engineering to make unattended installation and upgrade workflows more reliable.\nThis role combines practical Kubernetes expertise with customer communication and delivery ownership. You should enjoy investigating technical problems, working alongside customer teams, and taking responsibility for getting a deployment working in the environment where it will actually be used.\nYou will work closely with Valarian’s infrastructure, platform, product, and engineering teams. Your experience in the field will help shape our installation tooling, documentation, and deployment workflows, making each deployment more repeatable and easier to operate.\nSuccess means customers have a working platform they can confidently use and maintain, with clear operating procedures and a dependable relationship with Valarian.\nWhat you’ll do:\nLead customer installations from initial technical discovery and readiness assessment through deployment, validation, and handover.\n\nGather high-level requirements, including intended workloads, infrastructure constraints, integrations, security requirements, availability expectations, and acceptance criteria.\n\nWork with customer infrastructure and security teams to establish prerequisites across cluster capacity, networking, DNS, certificates, storage, identity, and access.\n\nInstall and configure ACRA using the Wizard and supported deployment workflows across cloud, on-premise, and customer-managed environments.\n\nAct as the primary technical contact during delivery, build trusted customer relationships, and communicate progress, blockers, responsibilities, and next steps clearly.\n\nPlan and execute ACRA upgrades, including compatibility checks, maintenance windows, backups, recovery procedures, and post-upgrade validation.\n\nHelp customers plan and carry out Kubernetes or OpenShift cluster upgrades, coordinating changes with the teams responsible for the underlying infrastructure.\n\nHelp configure, test, and improve supported unattended installation and upgrade workflows, including health checks, failure detection, and recovery.\n\nTroubleshoot installation and live deployment issues across Kubernetes, Linux, networking, storage, and application dependencies; work with engineering to resolve product defects.\n\nValidate agreed customer workflows and operational readiness before completing deployment or upgrade handover.\n\nMaintain deployment records, installation guides, and runbooks; train customer operators and provide agreed support after go-live.\n\nTurn recurring deployment problems and customer feedback into clear improvements to ACRA, the Onboarding Wizard, automation, and documentation.\n\nWhat we are looking for:\nStrong hands-on experience deploying, troubleshooting, and operating production software on Kubernetes.\n\nPractical Linux knowledge and a good understanding of networking, DNS, TLS, persistent storage, containers, and access controls.\n\nExperience delivering production upgrades and handling failed changes, including backup, recovery, and service validation.\n\nFamiliarity with Helm, GitOps, and infrastructure or deployment automation.\n\nExperience working directly with customers or external technical stakeholders, gathering requirements and managing delivery expectations.\n\nClear communication skills: you can explain an issue to an infrastructure engineer and give a concise, useful update to a customer stakeholder.\n\nStrong operational judgement: you know when to proceed, investigate further, pause a change, or escalate.\n\nAbility to take ownership of a deployment while working effectively with customer teams and engineering specialists.\n\nAbility to write useful scripts or small tools in Bash, Python, or a similar language.\n\nWillingness to work onsite with customers, travel as required, and support agreed maintenance windows.\n\nYour background could be in field engineering, professional services, technical implementation, infrastructure engineering, SRE, or technical support with substantial deployment responsibility. We care about evidence of successful delivery and sound judgement.\nNice to have\nExperience with OpenShift or Kubernetes in on-premise, bare-metal, restricted, or air-gapped environments.\n\nExperience delivering software in regulated, sovereign, government, defence, or other security-critical settings.\n\nFamiliarity with Terraform, Ansible, Argo CD, or comparable infrastructure and configuration tools.\n\nExperience with monitoring, secrets management, distributed storage, or Kubernetes networking.\n\nExperience improving installation tooling, writing operational documentation, or delivering customer training.\n\nBenefits:\nOur benefits are designed to ensure our employees feel taken care of and are proud to be a part of the Valarian team. We are committed to consistently enhancing our benefit package, taking into account the overall well-being and needs of our teammates.
