Résumé du poste

Vibe is hiring a Senior Platform/Infrastructure Engineer in Paris to own reliability across the production stack, from prediction serving to the bidding engine. You will ensure low latency, scale efficiently, and drive cost optimizations in a high-growth environment.

You will work on real-time data paths (Redis, Kafka), define SLOs, and enhance observability while collaborating with data scientists and other engineering teams. This role is hybrid in Paris with strong on-call expectations.

Qualifications

• You've owned latency-sensitive services in production, on-call included.
• Solid Kubernetes and cloud fundamentals. At ease debugging a p99 latency problem
• Observability experience: metrics, tracing, logs, and opinions about what makes an alert worth waking someone for.
• Infrastructure as code, CI/CD. You can ship the fix, not just find it.
• You're comfortable owning systems you didn't design. You'll be on the hook for this stack before you understand every model in it.

Responsabilités

• Own reliability across the production stack: prediction serving, the bidding engine, pacing, delivery. Define the SLOs, build the observability to see them, and shape how we run on-call.
• Bring p99 down on the serving path and run the bidding engine on fewer replicas without giving up latency.
• Work on the data layer under real-time serving. Redis comes first: access patterns, caching strategy, behavior when it degrades.
• Build a way to stress-test the platform end to end in staging so we find our ceiling before production does.
• Handle capacity planning and infrastructure cost as advertiser volume grows.
• Work closely with the data scientists shipping models into this stack, and with Benoît Delsart, who covers the platform and tooling side.
• Run incident response and make sure postmortems turn into changes that ship.
• Collaborate with other engineering teams, notably DSP, since our systems interact heavily with the rest of the stack.
