About the role

  • 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

  • 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.
Benefits
  • Comprehensive Health & Wellness: Robust medical insurance options to keep you and your family healthy.
  • Employer-Covered Insurance: We fully provide employer-paid Dental coverage, as well as Short-Term (STD) and Long-Term Disability (LTD).
  • Recharge & Refuel: We believe in a true work-life balance. You’ll start with 3 weeks of paid vacation, plus additional sick leave and paid company holidays to ensure you have time to recharge.
  • Growth & Mentorship: Access to world-class training and mentorship. We support your career trajectory, whether you’re looking to deepen your technical skills or move into leadership.
  • Impactful Work: Help protect global clients using the latest AI-enhanced security tools and GCP native technologies.
