Madrid, España Sg Tech A tiempo completo

At sg tech we are looking for a AI-Native Full Stack / Developer Experience Engineer responsible for designing and delivering next-generation developer experiences for the Global BaaS platform. The role owns developer portals, SDKs, sandbox environments, and AI-driven documentation and support agents.

Mid–senior profile with strong front-end and API DevEx expertise. AI experience is desirable but not mandatory.

Primary Responsibilities

Developer Portals & Frontend

- Build and maintain API developer portals using Apigee Developer Portal, React, Next.Js, and TypeScript.

- Implement developer-facing features: SDK generation (multi-language), semantic API discovery, usage analytics, and API monetization support (metering hooks).

- Implement front-end tools for SLA tracking, developer telemetry, and visualization of API workflows.

Sandbox, Testing & Documentation

- Own sandbox and testing environments (Postman collections, contract tests) for external partners and internal teams.

- Automate documentation and changelog generation with LLM-assisted tools;
own versioning and validation of docs.

Conversational Support & Developer Tools

- Provide conversational developer support (ChatOps) via ChatGPT Enterprise-backed agents, integrated into the portal and Slack.

- Collaborate with Platform (Global BaaS) for gateway integrations and Backend Leads for sample apps and domain examples.

DevEx Operations

- Maintain CI/CD for DevEx services and ensure observability (Prometheus, Datadog).

AI-related responsibilities are optional and can be acquired during onboarding.

Core Tech Stack

Frontend: React, Next.Js, TypeScript

Backend: Node.Js (NestJS/Express), Python (FastAPI)

API Management & Portal: Apigee Developer Portal

Testing & Sandbox: Postman, Pact, JMeter, K6

Observability: Prometheus, ELK, Datadog

CI/CD & IaC: GitHub Actions, ArgoCD, Terraform

AI Tools: ChatGPT Enterprise, GitHub Copilot, OpenAI/Azure AI for doc automation

Security: OAuth 2.1, OIDC, mTLS where applicable

AI-native components (semantic search, LLM agents, automation) are desirable but not mandatory.

AI-Native & DX Practices

- Use LLM-based generation for docs, changelogs, SDKs, and example code;
enforce review gates.

- Provide semantic search (vector DB-backed) in the portal for API discovery.

- Offer a conversational assistant with governed LLMOps practices and audit logging.

AI requirements can be acquired during onboarding.

Requisitos

Required Skills & Qualifications

- Strong proficiency in React, Next.Js, TypeScript, and Node.Js.

- Experience with Apigee Developer Portal and API SDK generation.

- Familiarity with OpenAPI 3.1, contract testing, and sandbox management.

- Experience integrating LLM-based documentation tooling and ChatOps assistants.

Solid front-end and API DevEx fundamentals are prioritized over AI expertise.

Preferred Qualifications

- Experience with semantic search, vector stores, and conversational AI for developer support.

- Familiarity with Camunda or Apache Camel for orchestrating developer tooling workflows.

- Proficiency in English and Spanish (tested).

AI-related experience is optional;
not a blocker.

About the Role

Owner of the developer experience: making APIs easier to discover, adopt, and integrate through excellent tooling, smart automation, and conversational support.
