Job Description

Hello, we’re L’Oréal. We’re not just building brands, we’re shaping how the world experiences beauty (and it takes a lot of cool jobs to do it). Intrigued? Keep reading, this might be the opportunity you’ve been searching for.

A Day in the Life

You will drive the technical execution for the L'Oréal GPT and some of our Employee AI Workstation products at So Tech. Working alongside a co-lead, you are the structural anchor of the pod – the one who ensures the architecture is sound, secure, and reliably delivered.

• Own the rigorous execution of our technical architecture (including AI Gateway and MCP Gateway) with minimal need for supervision.
• Enforce strict quality and security standards equally across all components, ensuring full compliance with Key IT Controls and AI Guardrails.
• Anticipate technical risks and system vulnerabilities deliberately, stopping issues before they become live incidents.
• Deconstruct complex skills-agent architecture problems into clear, logical steps.
• Take absolute ownership of technical debt, code quality, and delivery commitments.
• Step in to troubleshoot and resolve deep technical issues when the system requires it.

The pressure of multi-project delivery is high here. You won’t rely on charisma to get things done – you will succeed through undeniable technical discipline, focus, and an ability to hold the line on technical priorities without getting distracted.

We Are Looking For

You bring pure execution and structure. You are the pragmatic counterbalance in a dynamic team, building trust through consistent, high-quality delivery and risk anticipation.

You Bring

• Tech and Data Architecture Design:Alongside our transversal architect, you design robust, secure architectures and ensure seamless integration in the L'Oréal IT landscape.
• Problem Solving:Rigorously analyzing complex issues and operating efficient technical solutions.
• Prioritization:Maintaining strict focus on core technical priorities despite competing project pressures.
• Tech Service Delivery:Managing tech releases and deployments with consistent standards.
• Critical Thinking:Anticipating risks and making reasoned, deliberate technical judgments.

What’s In It For You

• A place for you to leave your comfort zone and grow beyond your potential (here, you’ll be encouraged to try new things and take risks!)
• Real responsibility from day 1, there’s no sitting on the sidelines at L'Oréal
• An environment where people of every ethnicity, social background, age, religion, gender and sexual orientation as well as people with disabilities are accepted, can speak up, will thrive and are celebrated!
• A place where you can contribute to something bigger! Many of our brands have societal/environmental causes to make a concrete difference

Who We Are

At L'Oréal, we expect a level of leadership that leaves a lasting impact. You won’t just manage a team‑you’ll actively mentor the next generation of talent and shape the strategic direction of your function. This is a space for leaders who are comfortable making hard decisions, challenging the consensus, and driving large-scale transformation. In Beauty Tech, our ambition is to exponentially augment L'Oréal's game‑changing science with cutting‑edge technologies, at scale. You’ll join a global community of Tech Experts, leveraging AI, data, and digital innovation to deliver unsurpassed beauty experiences. With state‑of‑the‑art infrastructure and a strong culture of continuous upskilling, you will directly impact our brands and businesses. We’re committed to guaranteeing inclusive recruitment processes and to advocating for hiring and promoting each candidate in an ethical and equitable way. The Group strictly prohibits discrimination against any applicant for employment because of the individual's gender identity or expression, sexual orientation, visible and/or invisible disabilities, socio‑economic and/or multicultural origins, health conditions, age, religion, or any other characteristics protected by law.
