About Poesis

Whoever builds the leading intelligence for finance will create far more than returns. Poesis is the AI-native investment firm running autonomous agents that predict markets, construct portfolios, and manage risk. Our founders managed institutional capital at Capital Group ($3T AUM) and led enterprise ML at Goldman Sachs and Amazon. We're building a new type of firm, where live capital is the training ground for an intelligence that compounds with every signal.

AI agents are a core part of how we make this a reality. We're looking for an experienced software engineer to help lead our agent engineering efforts. As the Agents Engineering Lead, you'll bring strong technical judgment and deep curiosity about what frontier models and harnesses make possible, translating emerging capabilities into production systems. You'll collaborate with Poesis leaders to set the vision and execute the development roadmap, with a unique opportunity to define the architecture that shapes how these systems are built and scaled across the organization.

• Strong familiarity with the modern AI stack (LLMs, tool use, orchestration, evaluation)

• Proficiency in Python and SQL, with bonus for TypeScript, Go, or Rust

• Basic understanding of financial markets and a personal or professional interest in investing

• Demonstrated experience designing, building, and deploying multi-agent systems in production environments; expertise in agent orchestration, tool calling, context window management, and agent grounding

• Proven ability to anticipate and address failure modes, with hands-on experience in observability and evaluation of agent systems
