Overview

We’re partnering with a company that in just over year has:

• Built category-leading agent technology
• Gained traction with some of the world’s top game studios

This is a founding-level hire, working directly with the founders to take agents from impressive demos → reliable, production systems that operate at scale.

• Design and scale multi-agent LLM systems handling thousands of concurrent workflows
• Own production ML systems, training, serving, and optimising large-scale / billion-parameter models
• Engineer systems that work in the real world, handling failure, edge cases, latency, and recovery
• Develop agents that operate across mobile, desktop, and varied environments without brittle logic
• Turn complex user journeys into autonomous, repeatable workflows
• Build evaluation and feedback loops (benchmarking, annotation, RLHF/SFT) to continuously improve systems
• Harden systems for production reliability, observability, and unattended operation
• Work across the stack, LLMs, backend systems, APIs, and infrastructure
• Collaborate directly with users to translate real problems into automation
• Operate as a founding engineer, shaping architecture, making trade-offs, and moving fast in ambiguity
