About The Position

Sparteo is hiring a Senior Platform Engineer to design, operate, and scale the infrastructure foundations that support its products. The Infrastructure & Cloud Services team operates a self-managed platform based on bare-metal infrastructure in the company’s own datacenters, Kubernetes at scale, and a self-managed network using BGP, its own AS, transit, and peering. The role owns critical parts of the stack, leads platform architecture decisions, and helps the team grow. It also contributes to infrastructure expansion in the US and platform-wide cost optimization.

The position involves close collaboration with product teams and stakeholders. Sparteo describes its work environment as flexible, with work possible from home or its urban offices in Paris, Lille, or London. The posting includes an unconfirmed location note about being within reach of datacenters for on-site interventions; it does not establish that as a final requirement.

• Strong networking fundamentals, including BGP, L2/L3, and load balancing.
• Strong communication skills with product teams and stakeholders.
• Fluent written and spoken English.
• Openness to AI-assisted tooling in daily workflows, using it to automate, document, and work faster.
• A pragmatic, analytical problem-solving approach; ability to work in a fast-moving environment, prioritize effectively, listen, and contribute to collective progress.

Responsibilities

• Design, implement, and operate the Kubernetes platform, including networking, ingress, GitOps, and configuration management.
• Own CI/CD pipelines and packaging, applying automation from provisioning through deployment.
• Operate the observability stack, including large-scale metrics and log management.
• Own runbooks and the alerting catalog to support platform reliability and actionable on-call practices.
