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\nIn this role, you will help build and operate the backend and platform services behind ACRA: our secure Kubernetes platform for controlled compute, data governance, and AI-driven security operations.\nYou will work mainly in Go, building services across backend engineering, Kubernetes, platform infrastructure, and security. This includes systems designed for reliability, scale, and security from the start, including how AI can help define, enforce, and reason about security controls.\nYou will join a focused engineering team that values ownership, direct feedback, and support. You will start with clear areas of work, then take on more autonomy over services and platform direction as you build context.\nThis is a strong fit for someone who wants to become excellent across backend, platform, Kubernetes, and security, and help build a serious security platform from an early stage.\nWhat you’ll do:\nAs part of the team, you will:\nDevelop backend services, APIs, and platform components using Go.\n\nOwn services from design and implementation through testing, deployment, and production monitoring.\n\nWork with Docker, Kubernetes, CI/CD, GitOps, and secrets management.\n\nBuild platform features for workload isolation, policy enforcement, audit logging, and identity-aware communication.\n\nDesign event-driven distributed systems for resilience and scalability.\n\nImprove metrics, logging, tracing, and incident response.\n\nWork with engineering and product teams to turn requirements into technical solutions.\n\nOwn specific platform areas and contribute independently.\n\nImprove how the team reviews code, deploys changes, and learns from incidents.\n\nWhat we are looking for:\nBackend engineering experience, with some exposure to Go.\n\nExperience building APIs, backend services, or microservices.\n\nExperience working with Docker and containers.\n\nExperience deploying to, developing on, or building with Kubernetes.\n\nUnderstanding of CI/CD pipelines and deployment workflows.\n\nFamiliarity with GitOps, Argo, container registries, secrets, or deployment security.\n\nUnderstanding of event-driven architecture, asynchronous workflows, or distributed systems.\n\nSystem design knowledge around reliability, scalability, observability, and failure handling.\n\nAbility to debug issues across applications, services, and infrastructure.\n\nInterest in why the platform is being built, not just what needs to be implemented.\n\nOwnership, curiosity, and ability to work independently.\n\nWillingness to learn across backend, platform, infrastructure, and DevOps.\n\nNice to have:\nSecurity, regulated, or high-trust environments such as defence, government, fintech, healthcare, critical infrastructure, or sovereign cloud.\n\nKubernetes security areas such as zero trust, workload isolation, identity-aware systems, network policy, service mesh, or policy enforcement.\n\nPlatform security practices such as secrets management, supply-chain security, admission control, auditability, and operational evidence.\n\nObservability and operations, including metrics, logs, traces, alerting, incident response, and debugging production systems.\n\nExperience in startup, platform, infrastructure, or product engineering environments with broad ownership.\n\nYou do not need to have worked with all of these. They are areas you may learn and build with us.\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. Here are the key benefits accessible to all employees at Valarian Technologies:\nEquity - because you have the right to own what you’re building\n\nA competitive salary - because we value your unique skills\n\nEmployer pension contributions - because you deserve a secure future\n\nPrivate health insurance - because your health is important to us \nHybrid work setup - because everyone has different needs\n\nRewarding company retreats and meetups that respect your work/life balance - because we love getting to know each other!\n\nLife at Valarian\nOur culture is built on inclusivity, compassion and flexibility - we want everyone to be empowered to achieve their goals at Valarian.\nThe work we do is vital, but so are the connections that make it happen. We thrive on the shared energy, spontaneous conversations, and mutual trust built when we spend time together. We operate on a hybrid model, gathering in our London office 3 days a week to support one another and collaborate.\nWe may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing 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 judgment. Final hiring decisions are ultimately made by humans.
