About the Role

What We're Looking For

• Technical depth and real familiarity with the LiteLLM product surface
• Obsessed with customers and making them successful with the product
• Obsessed with solving root causes rather than patching over problems
• Metrics-driven and hardworking, ready to move through a high volume of tickets
• A strong bias toward understanding problems deeply

• Competitive salary
