About the Role
We are seeking an AI Platform Engineer who combines practical technical expertise with an architectural perspective – someone who can build and operate AI solutions today while staying attuned to developments and their implications for St1's future.
You will be responsible for St1's AI platforms: the tools, infrastructure, security, and cost management that make AI accessible and reliable across the organization. You work hands-on with AI agents, gateways, pipelines, and platform services while maintaining a holistic view: how solutions interconnect, what risks exist, and how technical decisions impact the business over time.

- Manage AI gateways and ensure proper routing, logging, and control of AI traffic.
- Test and validate new AI opportunities practically before broader rollout.
AI Security and Governance
- Implement AI-specific security controls together with the CISO, such as DLP, AI gateways, shadow AI management, and protection against unsafe usage patterns.
- Ensure compliance with St1's AI policy and create transparency around AI usage.
- Maintain an up-to-date catalog of the organization's AI solutions.
- Serve as technical expert in St1's AI governance and advisor on which tools are available, approved, and appropriate.

- Identify optimization opportunities and contribute to cost-effective AI investments.
We Are Looking for Someone With
- 3–5 years of experience building and operating software or AI systems.

- Good understanding of the AI landscape: LLM platforms, agent frameworks, gateways, and development assistants.
- Ability to follow technology developments and translate trends into concrete recommendations.
- Knowledge of AI security, such as DLP, AI gateways, and shadow AI.
- Interest in AI FinOps and cost optimization.
- Strong communication skills and the ability to explain AI to both technical and business audiences.
