OVHai; Paris; Híbrido; EUR 60.000 - 90.000; Jornada completa

Descripción de la vacante

OVHai LLM seeks an infrastructure generalist to design, build, and maintain backend services and APIs that power our product stack in Paris. You’ll provision laptops, servers, cloud accounts, and GPU resources, while serving as the go-to for IT escalations and production incidents.

As the first line of defense on security, you’ll ensure patching, access control, and GDPR-compliant data handling, while automating CI/CD and infrastructure-as-code to improve efficiency.

Formación

• Real experience with systems and network administration (servers, IAM, networking).
• A security-first mindset — never assume, always lock down.
• Calm, clear communication when incidents occur or a laptop order is blocked.
• Comfort being on-call and owning incidents through to resolution.
• Pragmatic decision-making: prefer workable solutions over perfection.
• Fluent in both English and French (written and spoken).

Responsabilidades

• Design, build, and ship backend services and APIs the product depends on.
• Provision and maintain laptops, servers, cloud accounts, and GPU resources for the team.
• Be the primary point of contact for IT escalations and production incidents.
• Keep devices, accounts, and access secure — patching, access control, endpoint protection.
• Handle user data in the backend responsibly, in line with GDPR.
• Automate recurring work (CI/CD, infra-as-code) to avoid repeat tasks.

About Us

At OVHai LLM, we build large language models and design platforms and services around these models for specific use cases. We’re a tight-knit team of 15 researchers and engineers, united by curiosity and a shared drive to push the boundaries of what LLMs can do — from training and fine-tuning to rigorous evaluation and benchmarking.

Our team is genuinely diverse and multicultural, bringing together different backgrounds, perspectives, and ways of thinking. That mix is core to how we work: we believe the best research comes from teams that challenge each other’s assumptions and learn from one another every day.

We take our work seriously, but not ourselves. Expect a collaborative, low-ego environment, plenty of interesting debates, shared lunches, and lots of fun — alongside real opportunities to contribute to cutting-edge LLM research from day one.

The Role

You’re a generalist on the infrastructure side: you build the backend services and APIs our product runs on, and you’re also the reason everyone here has a working laptop, cloud access, and secure systems. We’re small enough that these two jobs are still one job. You’re comfortable with that tradeoff, and you’re the first name people think of whether the fire is in the code or in the network.

What You Will Do

• Design, build, and ship backend services and APIs that the rest of the product depends on
• Provision and maintain laptops, servers, cloud accounts, and GPU resources for the team
• Be the primary point of contact, both for corporate IT escalations and for production incidents
• Keep devices, accounts, and access secure — patching, access control, endpoint protection
• Handle user data in the backend responsibly, in line with GDPR (consent, retention, access requests)
• Automate the recurring work (CI/CD, infra-as-code) so the same manual task doesn’t happen twice

What We Look For

• Real experience with systems and network administration (servers, IAM, networking)
• A security-first mindset — you default to “is this locked down,” not just “does this work”
• Calm, clear communication when something is on fire, whether that’s a bug or a blocked laptop order
• Comfort being on-call and owning incidents through to resolution
• Pragmatism — you know when “good enough and shipped” beats “perfect and late”
• Fluent in both English and French (written and spoken).

Nice to Have

• Experience liaising with an external or corporate IT department
• Familiarity with infrastructure-as-code and observability tooling
• Exposure to GPU cluster management for ML workloads
• Willingness to make small frontend changes when needed

The Recruitment Process

• A 15-minute introductory call with the engineering team to discuss the role
• An interview and technical use case assessment with our engineering team
• An HR interview to assess soft skills
• Debriefing session

Note: this role is scoped for a small team. As the company grows, this job is a natural candidate to split into a dedicated IT/infrastructure role and a dedicated product engineering role.
