[Hiring] Senior Software Engineer - AI Integration @Foresite

Role Description

Foresite is looking for a Senior Software Engineer with strong, hands-on AI experience to help shape how AI gets built into our platform. We are a Managed Security Services Provider (MSSP) building the next generation of AI-powered security operations.

What You'll Do:

• Design and ship the systems that connect LLMs to real security workflows — from RAG pipelines over threat intelligence to agentic automation that handles triage and investigation steps that currently require human effort.
• Influence our AI architecture, product direction, and the standard for how the team builds with LLMs going forward.
• 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.

Qualifications

• 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.
• Deep proficiency in React 18/19 and TypeScript.
• Comfortable with React Router v7 and modern routing patterns.
• Comfortable designing schemas, writing queries, and reasoning about performance across PostgreSQL and Firestore.
• Experience designing secure multi-tenant AI architectures.
• Strong understanding of scalable and highly available cloud-native system design.
• Experience working closely with product teams to ship user-facing features.

Requirements

• Knowledge of Infrastructure as Code (IaC) using Terraform to automate, orchestrate, and manage cloud platform resources effectively.
• Familiarity or hands-on experience with Google Cloud Security products (e.g., Security Command Center, SecOps, Mandiant).
• Experience building autonomous AI agents, multi-modal applications, or complex prompt orchestration pipelines.

Benefits

• Comprehensive Health & Wellness: Robust medical insurance options to keep you and your family healthy.
• Employer-Covered Insurance: Fully provided employer-paid Dental coverage, as well as Short-Term (STD) and Long-Term Disability (LTD).
• Recharge & Refuel: Start with 3 weeks of paid vacation, plus additional sick leave and paid company holidays.
• Growth & Mentorship: Access to world-class training and mentorship to support your career trajectory.
• Impactful Work: Help protect global clients using the latest AI-enhanced security tools and GCP native technologies.
