• Partner with product, design, trading and backend teams; communicate tradeoffs, estimate work and take accountability for delivery.
• Write automated tests, investigate production issues, instrument applications and improve reliability and performance.
• Use modern AI development tools (such as Cursor, Claude Code, GitHub Copilot or equivalent) responsibly to accelerate coding, debugging, testing, documentation and code review.
• Design and implement AI-powered product features, agents and workflow automations using LLM APIs, tool/function calling, structured outputs, retrieval, and integrations with internal services.
• Build reliable agent workflows with evaluation, observability, access controls, human approvals where appropriate, and safeguards for sensitive client and trading data.
• Other duties as assigned
