Senior Software Engineer, Agents - Hiring Sprint
About The Position
Airbyte is building the runtime that powers trustworthy AI agents. We believe the future isn't simply giving LLMs access to APIs, it's building the infrastructure that allows agents to reason over enterprise context, retrieve evidence, invoke actions safely, and explain every decision they make. We're building the AI Runtime that sits between language models and enterprise systems. Our runtime resolves entities across hundreds of business systems, assembles the right context, chooses the appropriate connectors and skills, validates evidence, enforces permissions, executes actions safely, and returns responses users can trust. The interface is becoming dramatically simpler: "Investigate this customer and tell me what changed." Behind that simple request is an intelligent runtime responsible for orchestration, routing, retrieval, evaluation, evidence generation, permissions, and action policies. We're early. The architecture is taking shape but there's enormous room to define how this works. You'll help build both the runtime infrastructure and the user-facing experiences that make it real.
Requirements
- 7+ years of software engineering experience building production systems.
- Deep understanding of distributed systems and backend architecture.
- Experience building AI applications using LLMs, agents, RAG, MCP, or modern AI frameworks.
- Strong software engineering fundamentals including APIs, concurrency, testing, and system design.
- Experience building developer platforms, orchestration systems, or workflow engines.
- Ability to rapidly prototype while maintaining production quality.
- Strong product instincts and comfort operating in ambiguous environments.
- Exceptional written communication skills.
- A bias toward ownership and shipping.
Nice To Haves
- Experience building AI agents or agent frameworks, including evaluation systems.
- Familiarity with orchestration frameworks (LangGraph, Temporal, MCP, or similar).
- Experience with retrieval systems, vector search, or knowledge graphs.
- Experience building developer tools or platform infrastructure.
- Experience with data infrastructure including Kafka, Iceberg, Postgres, Spark, or modern data warehouses.
Responsibilities
- Build the AI Runtime: Design and implement the orchestration layer that turns natural-language intent into reliable execution.
- Build systems for entity resolution, context assembly, connector orchestration, and evidence retrieval.
- Develop reusable Skills that encapsulate business workflows and domain expertise.
