With offices in London, Málaga and Madrid, we’re building products that give customers maximum security, sovereignty, and control over their digital assets. We operate as a lean and innovative organisation: bringing brilliant solutions to market - using cutting edge, cloud‑native technologies.

If you’re passionate about shaping the future of blockchain infrastructure, collaborating with smart, curious colleagues, and making an impact from day one – we’d love to hear from you.

About You

We’re looking for a Senior Platform Engineer who thrives in a collaborative environment. You’re curious and inventive, with a natural drive to explore new ideas and turn them into meaningful outcomes. You enjoy tackling complex challenges, working across disciplines, and contributing to projects that push the boundaries of what’s possible in our Technology & Security team.

You thrive in an international and forward‑thinking setting and are passionate about shaping the future of digital products and services. You combine creativity with rigour: transforming concepts into real impact for our customers.

As a Senior Platform Engineer at Clavium, you'll be a key player in maintaining and improving the infrastructure that powers our blockchain platform. You'll work alongside cross‑functional teams to ensure the reliability, performance, and scalability of our systems. Your responsibilities will include administering multiple Kubernetes clusters, managing complex system upgrades, and driving improvements in how we deploy and operate our services.

What you'll do

Kubernetes Management: Administer and optimise multiple Kubernetes clusters, supporting a variety of systems across multiple private and public cloud environments.

System Upgrades: Plan and execute upgrades for large, complex systems in collaboration with key staff across multiple sites, ensuring minimal disruption and maximum efficiency.

Release Management: Oversee technical releases, including managing software deployments, de‑risking processes, and reviewing change requests.

Design Evaluation: Identify and evaluate alternative design options, weighing the trade‑offs to ensure optimal solutions.

Cross‑Functional Collaboration: Work closely with engineering teams to ensure seamless integration of systems and services.

Automation: Drive automation improvements and help refine deployment pipelines to increase operational efficiency.

Incident Management: Participate in incident response and contribute to the root cause.

Participate in an on‑call rota (typically every 4 to 6 weeks) providing out‑of‑hours support for critical incidents only – covering weekdays from 5pm to 8am and 24/7 at weekends; non‑critical issues are handled during standard office hours.

What you'll bring

Deep Kubernetes Expertise: Proven experience managing Kubernetes clusters at scale, including troubleshooting, scaling, and optimising for high availability and performance.

Cloud Experience: Familiarity with public (GCP, AWS) and private clouds and experience working with containerisation technologies like Docker.

Infrastructure as Code (IaC): Strong experience with IaC tools such as Terraform, Ansible, or similar.

Continuous Integration & Deployment (CI/CD) concepts and tools: Experience with Gitlab is highly desirable, with knowledge of build tools (Maven, Gradle), binary repositories (Nexus, Artifactory) and code quality tools (SonarQube).

Release Management: Experience managing technical releases, coordinating deployments, and mitigating risks in a fast‑paced environment.

Observability & Monitoring: Expertise in observability tools such as Prometheus, Grafana, Fluentd, and Kibana to ensure system health and performance.

Programming & Scripting: Proficiency in scripting languages (e.g., Bash, Python) and understanding of coding concepts.

System Administration: Strong background in Linux system administration and network diagnostics

Collaboration Skills: Ability to collaborate across teams and geographies, with strong communication skills for both technical and non‑technical audiences.

Problem‑Solving Mindset: A strong problem solver who can design scalable, efficient solutions to complex challenges.

A typical day with us
