Job Description

Software Development Specialist – Platform Engineer – API, Identity

VOLL

• Lead the evolution of the API Gateway as a secure exposure layer, complementing the existing WAF with rate limiting, schema validation, and self-service onboarding of new APIs. • Define and evolve the authentication and authorization architecture (OAuth2, OIDC, JWT) for APIs exposed to external clients. • Design security guardrails for the public exposure of MCP servers: client authentication, tools scope, per-client/tenant limits, and abuse prevention. • Define authorization patterns between internal services (mTLS, service-to-service access policies). • Build reusable libraries and components that product teams integrate to expose APIs secure-by-default. • Serve as the technical contact with Cybersecurity/AppSec to align the externally exposed surface. • Identify and prioritize security gaps in external exposure before they become incidents. • Review product teams' architectures that expose new services externally, focusing on authentication and authorization. • *Objectives may extend beyond this initial scope, involving other challenges focused on architecture, back-end, messaging, and security as the platform and team needs evolve.*

Job Requirements

  • Proven experience as a platform engineer or senior software developer building tools/infrastructure consumed by other teams.
  • API Gateway architecture and management (Kong, Apigee, AWS API Gateway, or similar).
  • Authentication and authorization applied to external APIs: OAuth2, OIDC, JWT, key rotation.
  • Service authorization in distributed environments (service-to-service), including mTLS.
  • Secure software development (OWASP), with a focus on applications exposed externally.
  • Microservices architecture design and event-driven architecture.
  • Bachelor's degree in Computer Science, Software Engineering, Information Systems, or related fields.
  • Nice to have:**
  • Experience exposing MCP servers or similar integration protocols with AI agents.
  • Previous experience working with Cybersecurity/AppSec.
  • Experience with VPC Lattice, ECS Service Connect, or service mesh.
  • Advanced English and/or Spanish.
