AI Software Engineer

Rockstar • San Francisco, CA

7d • Onsite

About The Position

Rockstar is recruiting for a well-funded seed-stage startup building the Agentic Execution System for global trade. Their agents don't assist with the work — they do it, reasoning over a live context graph of the business and executing actions with real financial consequence. They move real goods and real money for some of the largest enterprises in the world. The company is backed by leading VCs in NYC and SF, and the team brings deep experience across supply chain, financial technology, and applied AI.

Requirements

• 4+ years of experience in high-quality engineering environments
• Hands-on experience building agent applications: tool calling, MCP, context engineering
• Strong proficiency in Python, TypeScript, or similar
• Comfort with AWS/GCP
• Judgment about model tradeoffs: the ability to build the most reliable, cost-efficient system, not just the most impressive demo

Nice To Haves

• Experience with LLM post-training and evaluation
• Proficiency with Neo4j or other graph databases (or the drive to learn fast)
• Startup experience: the ability to think like a PM and an engineer in the same conversation
• High ownership, direct communication, and a bias for action
• Interest in recruiting and mentoring future engineers

Responsibilities

• Owns the core of the system: the agentic harness that handles tool routing, policy, and memory, and the context graph it reasons over.
• Build the agentic harness at the center of the platform: tool routing, policy enforcement, memory, and grounding for agents that execute real work end-to-end.
• Build a context graph of the physical economy: ingesting unstructured, contradictory data from emails, documents, and legacy systems and resolving it into a single source of truth.
• Build evaluation and reliability infrastructure that makes agent reasoning safe enough for financial actions.
• Build the technical foundation of APIs, interfaces, and infrastructure that scales with customer usage and product complexity.
• Ship to production, work directly with how enterprise customers operate, and shape what the platform becomes.
