Principal Engineer, Agentic Engineering

Bullish is an institutionally focused global digital asset platform that provides market infrastructure and information services. They are seeking a Principal Engineer to lead the technical authority for AI and agentic engineering, shaping architecture and driving the shift towards AI-native software delivery.

Responsibilities:

• Build the agent infrastructure that lets AI agents discover each other, communicate, and coordinate — so any team can deploy an agent and it joins the ecosystem
• Evolve our autonomous coding pipeline — task in, pull request out, with deterministic multi-agent execution, full cost control, and human review before merge
• Make engineering standards executable — encoding conventions as AI behaviours that activate in developer workflows, not documents pinned to a wiki
• Transform the delivery pipeline — auditing every manual gate and either automating it, replacing it with an agent, or justifying its retention as a deliberate human decision point
• Own AI infrastructure end to end — model routing, LLM proxy, cost attribution, evaluation frameworks, and observability for production AI systems
• Set the technical direction for AI and agentic systems across the engineering organisation
• Design and build production systems: agent orchestration, autonomous coding pipelines, LLMOps infrastructure
• Stay hands-on: write code, review PRs, debug production issues, and set the technical bar
• Evaluate new models, frameworks, and techniques as the landscape evolves — and bring what works into the organisation
• Establish metrics and observability for agent output quality, cost, and throughput
• Recruit and mentor engineers as the function grows, while remaining a primary contributor yourself
• Partner with the AI Enablement team to provide the technical foundation for business team AI adoption
