• Hands-on Agentic AI experience
• A proven ability to lead and influence technical and non-technical stakeholders
• Strong system design and architecture skills
• A track record of mentoring other engineers

Why You'll Love It

• You’ll work with Agentic AI in production on a live commercial system.
• You’ll own the platform. It's your platform and your call.
• Your voice will count. You’ll sit at the table with engineering, product and commercial leaders.
• You’ll hit the ground running. A structured 2–4 week onboarding gets you delivering quickly.
