About the Role

Extend is hiring a Senior AI Software Engineer, Internal Enablement (remote, US). You'll build an agentic platform for non-engineering roles — secure agent infrastructure, MCP connectors, and skill libraries that enable company-wide AI tooling adoption.

Responsibilities:

  • Design and deploy secure MCP connectors to internal systems and third-party SaaS (finance, CRM, data warehouse, expense management, analytics, support, ATS)
  • Build and maintain a shared library of reusable agent skills with review and publishing governance
  • Develop agent infrastructure and tooling so non-engineers can create reusable agent skills securely and reliably
  • Build a meta-agent that discovers APIs, scaffolds MCP servers, and provisions access automatically
  • Establish credential scoping, OpenTelemetry instrumentation, and least-privilege security patterns
  • Own the employee experience through onboarding, documentation, and adoption feedback loops
  • Design credential vending and risk-tier models for agent skills
  • Instrument the platform end-to-end with observability tooling

Requirements:

  • 5+ years shipping production systems
  • Proficiency in Python, TypeScript/Node, or Rust
  • Track record building developer tooling, SDKs, or internal frameworks measured by adoption
  • Real third-party integration experience (OAuth, credential scoping, webhooks, pagination, rate limiting)
  • AWS comfort (Lambda, API Gateway, DynamoDB, S3, managed agent runtimes)
  • Direct experience with Claude Code, MCP, or another agent framework (LangChain, CrewAI, AutoGen, OpenAI Agents SDK)
  • Production credential management (OAuth 2.0/OIDC, API key vending, secret rotation)
  • AWS security fundamentals (IAM, KMS, Lambda, serverless attack patterns)

Nice to have:

  • AWS CDK, CloudFormation, or other IaC
  • OpenTelemetry/Coralogix experience
  • Platform engineering or internal developer platform background
  • Early-stage startup IC experience
  • LLM application security (OWASP Top 10, prompt injection, agent sandboxing)

Compensation: $160,000–$180,000 base + equity. Benefits: full medical/dental/vision, flexible PTO, 401(k).
