About the role

Key responsibilities & impact

Design and build AI-powered workflows that serve both internal analysts and external customers across guided security operations.
Own the AI architecture end-to-end: model selection, prompt engineering, RAG pipelines, agent orchestration, and evaluation frameworks.
Optimize for cost and performance — manage token budgets, reduce latency, and build instrumentation so we know exactly what our AI spend buys us.
Collaborate with product and engineering to identify where AI creates real leverage and where it doesn't.
Mentor engineers on LLM best practices and raise the AI literacy of the broader team.

Requirements

What you’ll need

5+ years of software engineering experience with strong fundamentals (you write production code, not just notebooks).
Deep, practical experience using Agent Development Kit.
Proven track record of integrating LLMs into production environments - prompt engineering, context management, RAG architectures, agent frameworks, evaluation and observability.
You are deeply proficient in React 18/19 and TypeScript.
Comfortable with React Router v7 and modern routing patterns.
Experience designing schemas, writing queries, and reasoning about performance across PostgreSQL and Firestore.
Familiar with modern ORMs and use runtime validation to enforce data integrity at system boundaries.
Experience designing secure multi-tenant AI architectures — building LLM integrations that enforce strict data isolation between customers.
Strong understanding of scalable and highly available cloud-native system design.
Experience working closely with product teams to ship user-facing features.
