📋 Description

• Own the architecture, development, and evolution of Superagent, the core agent harness powering conversations, tool calls, and multi-step agentic workflows • Design and optimize the agent execution loop for latency, reliability, token efficiency, cost, and task completion • Build and improve context management, memory/state handling, tool routing, function schemas, structured outputs, retries, and error recovery • Build and maintain agent evaluation infrastructure to measure quality and guide engineering decisions with data • Integrate and benchmark multiple LLM providers and models • Implement caching, batching, parallel tool execution, and prompt/context compression • Build observability and instrumentation across agent runs, including tracing, logging, metrics, and regression detection • Extend and customize underlying agent frameworks when existing abstractions are insufficient • Build reliable integrations with evolving AI and tool ecosystems • Work with product engineering teams to expose clean abstractions while keeping harness complexity behind the platform • Debug and resolve complex issues across non-deterministic, distributed, and model-driven systems

🎯 Requirements

• 4+ years of experience in software engineering, backend engineering, or systems infrastructure • Strong proficiency in Python and/or TypeScript • Hands-on experience building or operating LLM-based agents in production • Strong understanding of tool calling, function schemas, context limits, structured outputs, model failures, and unreliable LLM behavior • Experience with at least one agent framework such as LangGraph, OpenAI Agents SDK, CrewAI, AutoGen, or a custom/homegrown agent harness • Strong understanding of agent orchestration and multi-step workflows • Experience with evaluation suites, benchmarks, A/B testing, or other measurement systems for AI products • Strong understanding of concurrency, caching, profiling, performance optimization, and latency/cost tradeoffs • Experience working with LLM APIs and production AI infrastructure • Excellent debugging and problem-solving skills for complex and non-deterministic systems • Passion for technology, self-driven, proactive, and possessing a strong builder mindset • Optional: contributions to open-source agent frameworks, LLM tooling, or AI infrastructure • Optional: experience with RAG pipelines, vector databases, or long-term memory systems • Optional: familiarity with MCP or similar tool-integration standards • Optional: experience with LLM inference infrastructure, model routing, rate limits, fallbacks, or high-volume model APIs • Optional: experience with LangChain, LlamaIndex, LangGraph, DSPy, or similar AI infrastructure frameworks • Optional: experience with Kubernetes, Docker, cloud infrastructure, or distributed systems • Optional: experience building internal developer platforms or infrastructure used by multiple engineering/product teams • Optional: strong background in observability, distributed tracing, and production reliability • Optional: contributions to open-source projects or personal AI infrastructure projects

🏖️ Benefits

• Competitive salary and benefits package • Culture that encourages ownership, experimentation, learning, and data-driven engineering • Direct influence over the architecture and technical roadmap • Collaboration with a passionate and talented team • Work on real production-scale AI systems
