Diabolocom is building an AI-first communication platform and is looking for a Head of Infrastructure to own and scale the infrastructure foundation behind this platform. This role involves leading an infrastructure organization combining carrier-grade voice systems, on-premise data centers, distributed systems and AI workloads, while building the operational maturity required to support 2x growth.

Responsibilities

Own infrastructure reliability and operations across the whole stack: incident management, monitoring, alerting, post-mortems and prevention of recurring failures
Improve operational visibility across infrastructure teams: identify bottlenecks, improve processes and drive continuous improvement
Improve capacity planning, connecting business growth and infrastructure needs
Lead the evolution of network and telecom infrastructure: topology, connectivity, carrier relationships, routing, redundancy and voice platform performance and reliability
Own on-premise infrastructure operations: data centers, hardware, storage, connectivity and deployment practices
Drive scalability and reliability of stateful infrastructure: PostgreSQL, ClickHouse, Kafka, RabbitMQ, Redis and other critical systems
Support the evolution of AI infrastructure, including GPU workloads and compute clusters
Drive infrastructure improvements with automation, observability and tooling
Partner with engineering teams to ensure applications run reliably on our platforms
Lead and grow the Infrastructure team across Networking, SRE, Stateful Systems, Voice and Data Center squads

Requirements

Deep expertise in at least 2–3 infrastructure domains, such as networking, SRE/reliability, database administration, telecom/voice infrastructure, or hardware/on-premise infrastructure
Proven experience building and improving infrastructure operations: establishing processes, improving reliability practices, driving incident management and creating effective ways of working across multiple domains
Experience leading technical teams where different groups own different areas of infrastructure (e.g. networking, SRE, databases, systems or platform engineering)
Strong hands-on mindset: you stay close to technology and lead through context and expertise
Self-taught, hands-on background: you have grown technically by solving complex problems beyond your formal role
Fluent English, written and spoken
Ability to work onsite in Paris
