About the role

• You’ll own the Machine Learning Inference Infrastructure at Photoroom, powering millions of AI requests every day across GPU-based systems.

• You’ll be responsible for the infrastructure that deploys and runs machine learning workloads, partnering closely with ML engineers to ensure services remain reliable, scalable and cost-efficient.

• You’ll design and build cloud-agnostic infrastructure solutions that support both current and future AI workloads. Requests can range from milliseconds to several seconds and process payloads of tens of megabytes.

• You’ll work across the full infrastructure lifecycle, from architecture and implementation through to monitoring, optimisation and incident management, using tools such as Datadog to maintain system health.

• You’ll build and improve systems for load balancing, autoscaling, queuing and workload orchestration, ensuring consistent performance under rapidly growing demand.

• You’ll work directly with engineers across ML, Product, Mobile and Web teams to identify bottlenecks, improve deployment workflows and enable faster iteration.

• You’ll monitor production systems, analyse usage patterns and make infrastructure decisions based on real-world performance and user impact.

• Optional: Participate in the team’s on-call rotation to help maintain platform reliability.
  

About you

• You have experience designing and operating large-scale distributed systems with high availability and reliability requirements.

• You have hands-on experience with load balancing, autoscaling, queuing systems and traffic management at scale.

• You have worked on low-latency, real-time backend systems and understand how to optimise for performance and throughput.

• You have experience building resilient, redundant infrastructure capable of handling failures gracefully.

• You have designed and operated platforms that deploy and run containerised workloads at high scale while maintaining an excellent developer experience.

• You have experience supporting workloads that vary significantly in duration, from milliseconds to several seconds.

• You are highly pragmatic and focus on delivering business impact quickly, leveraging existing tools and frameworks where appropriate rather than reinventing solutions.

• You demonstrate strong ownership and are comfortable making technical decisions independently while collaborating effectively across teams.

• You have previously worked in a high-growth startup or similarly fast-moving environment.

• You enjoy learning from others, sharing knowledge and contributing to a collaborative engineering culture.

• Experience supporting machine learning infrastructure or GPU workloads is a plus, but not required.

• You are fluent in English (French is not required).
