About the Role
Join a core product team building agentic AI systems that automate complex, multi-step workflows across regulated and enterprise domains. You will ship production LLM services and help make them reliable, safe, and useful for customers.
What You'll Do
-
Design and maintain agentic systems for workflows across healthcare, legal, fintech, logistics, and compliance.
-
Build and operate RAG pipelines, including vector databases, embeddings, indexing, and domain-specific search.
-
Develop multi-agent orchestration, tool-calling, memory, and reasoning components.
-
Create evaluation, testing, and safety infrastructure to measure performance and catch regressions.
-
Deliver full-stack AI features, from APIs and data models to frontend and backend code, deployment, monitoring, and ongoing operations.
-
Work with product and design partners to prioritize work, define success measures, and improve features using user feedback and telemetry.
What We're Looking For
-
Two to eight years of software engineering experience building and shipping user-facing or backend products, preferably at a startup or product-focused company.
-
Professional experience deploying LLM-based services, including prompt design, orchestration, and tool integration.
-
Proficiency with Python and TypeScript/React or equivalent, plus cloud platforms such as AWS or GCP and relational or NoSQL databases.
-
Working knowledge of RAG, vector databases, embeddings, and retrieval pipelines.
-
Experience building automated tests, evaluations, and monitoring for production AI systems, as well as API-driven, high-throughput systems and real-time features.
-
Familiarity with agent or workflow frameworks such as LangGraph or CrewAI, and orchestration tools such as Temporal or Trigger.
-
Experience with multi-tenant or enterprise systems, regulated industries, fine-tuning, or multimodal models is useful.
