We are seeking a Staff Software Engineer for the  Tools Team to lead the evolution of our custom in-house web applications. This team drives our Call Centers and Supervised Identity Verification flows—the 'front door' of the premier digital wallet.

In this role, you won't just be maintaining legacy systems; you will champion an AI-native engineering culture. We leverage Claude and the Model Context Protocol (MCP) to supercharge our development lifecycle, while architecting production-grade solutions on Google Vertex AI to build agents that automate complex, manual call center functions, streamlining how our members interact with identity verification. You will oversee the intersection of Ruby on Rails, GoLang, and cutting-edge LLM orchestration to build a best-in-class, secure, and AI-augmented authentication experience.

• AI Orchestration & Agent Design: Lead the technical vision for integrating LLMs (specifically Claude) into our internal tools. Design and deploy autonomous agents that automate manual call center workflows.
• Product Evolution: Lead the technical vision for member support-facing verification UI flows, ensuring AI-assisted tools are seamlessly integrated into the agent and member experience.
• Shared Infrastructure: Develop shared UI components and API patterns that support scalable, multi-product verification workflows and AI-driven automation.
• System Integrity: Ensure all AI-driven automations comply with strict IAM, security, and data protection standards.
• Mentorship & Excellence: Mentor engineers on prompt engineering, agentic workflows, and modern full-stack best practices (Rails/Go/React).
• Instrumentation: Lead experimentation efforts, including A/B testing AI agent performance versus manual flows and detecting fraud through UX signals.

• Bachelor's degree in Computer Science or a related field.
• 10+ years of experience in full-stack engineering, with a proven track record of scaling customer-facing applications.
• 1+ years of hands‑on experience with LLM integration (Claude/OpenAI) and building agentic workflows. Familiarity with MCP (Model Context Protocol) or similar architectural patterns for connecting LLMs to data.
• 5+ years of experience in Ruby on Rails, GoLang, and React/Type Script.

• Architecture: Strong understanding of component-driven design, state management, and building secure backends with Postgre
  
  SQL.
• Leadership: Proven ability to influence cross-functional stakeholders and set technical direction in fast-paced environments.
• Automated Support Systems: Experience building or maintaining 'Human-in-the-loop' AI systems within a call center or support environment.
• Identity & Security: Deep understanding of identity verification, regulatory frameworks (NIST, IAL2), or IAM digital security.
• Scalable Tooling: Familiarity with design systems, shared component libraries, and modular SDK design.
• Data Transformation: Experience with data pipeline tools for feature flags, transformation, and secure transmission.
