Systems Engineer, MCP Portals

Role Requirements

  • Experience building and operating reliable distributed systems, backend services, network services, or infrastructure products in production.
  • Strong programming skills in TypeScript, JavaScript, Go, Rust, C++, or another systems-oriented language.
  • A solid understanding of HTTP, APIs, proxies, streaming connections, and common distributed-systems failure modes.
  • Experience debugging production systems using logs, metrics, traces, error reporting, and customer-provided evidence.
  • Ability to reason carefully about security boundaries, credential handling, concurrency, state management, and backward-compatible deployments.
  • Clear written and verbal communication skills, with the ability to coordinate investigations and solutions across team boundaries.

Nice to Have Skills

  • Experience with authentication and authorization technologies such as OAuth 2.0, OpenID Connect, JWTs, PKCE, or policy-based access control.
  • Experience with the Model Context Protocol or other rapidly evolving application protocols. Prior MCP experience is helpful but not required.
  • Familiarity with the Cloudflare Developer Platform, or other serverless edge-computing platforms.
  • Experience building gateways, forward proxies, identity systems, developer platforms, or Zero Trust and data loss prevention products.

Role Responsibilities

  • Design, build, and operate the globally distributed services that connect MCP clients to authorized upstream MCP servers.
  • Evolve our implementation as the MCP specification changes.
  • Build secure authentication and authorization flows involving Cloudflare Access, OAuth, identity, and delegated access to upstream services.
  • Improve the reliability, scalability, latency, and resource efficiency of multi-tenant systems built on the Cloudflare Developer Platform.
  • Develop observability through structured logs, metrics, traces, dashboards, and actionable alerts, and participate in production support and incident response.
  • Investigate customer issues across multiple services and teams, distinguishing product defects from upstream failures, policy configuration, and infrastructure dependencies.
  • Collaborate with product, security, and engineering partners to turn customer needs and emerging standards into well-tested, maintainable product capabilities.

Perks and Benefits

  • Compensation may be adjusted depending on work location.
  • For Bay Area based hires: Estimated annual salary of €45,000-62,000.
