Experiencia práctica diseñando, configurando y desplegando API Proxies en Google Apigee (Apigee X o Hybrid) para integración interna y exposición externa. Experiencia sólida integrando microservicios con Google Cloud Storage para carga, descarga, streaming y gestión segura de archivos. Experiencia con el ecosistema GCP: Cloud SQL, Cloud Pub/Sub y Secret Manager. Experiencia instrumentando observabilidad distribuida con Elastic APM. Capacidad demostrable para trabajar en entregas incrementales (vertical slicing): dividir soluciones complejas en iteraciones cortas y funcionales.\nRequisitos técnicos (hands-on)Java 25: manejo de características modernas del lenguaje, como Virtual Threads, Pattern Matching y Structured Concurrency.\nSpring Boot 3+: Spring Data JPA, Spring Security y Spring Cloud GCP.\nApigee:\nConstrucción y mantenimiento de API Proxies internos y externos. Políticas de seguridad: OAuth 2.0, JWT, API Keys y mTLS. Control de tráfico: Spike Arrest, Quota y Rate Limiting. Mediación y transformación de datos (JSON/XML) y manejo estandarizado de errores (FaultRules). Configuración de Target Servers y Service Callouts.\nGoogle Cloud Storage: uso del SDK oficial de Java para transferencias eficientes (multipart y streaming), metadatos, permisos IAM y generación de Signed URLs.\nCloud SQL (PostgreSQL): modelado relacional, configuración de pools de conexión (HikariCP) y optimización de consultas.\nCloud Pub/Sub: flujos de eventos asíncronos con publicación y suscripción desacopladas.\nGCP Core: despliegue en GKE y gestión de variables y claves en Secret Manager.\nDiseño de APIs: contratos bajo OpenAPI 3.1 / Swagger y diseño guiado por especificaciones (Spec-Driven Development), definiendo y validando los contratos antes de implementar.\nObservabilidad: instrumentación con agente Java de Elastic APM u OpenTelemetry para trazar transacciones entre Apigee, el backend y servicios externos; monitoreo de latencia y errores en Kibana.\nTesting: JUnit 5, Mockito y Testcontainers (con PostgreSQL y emuladores de GCP).\n¿Qué harás?\nTe sumarás a un proyecto en una importante institución financiera de Chile, como desarrollador/a backend hands-on. Serás responsable de construir, desplegar e integrar microservicios en Java 25 con Spring Boot 3 y de implementar la capa de API Management en Google Apigee.\nDiseñarás API Proxies para tráfico interno y externo, integrarás los microservicios con Google Cloud Storage y otros servicios de GCP, y trabajarás con un enfoque de entregas incrementales apoyado en herramientas de desarrollo asistido por IA. Toda la solución se monitorea de extremo a extremo con Elastic APM.\nResponsabilidadesMicroservicios: construir e integrar microservicios escalables con Java 25 y Spring Boot 3, con buenas prácticas de diseño, seguridad e idempotencia.\nApigee: configurar y mantener API Proxies para tráfico interno y externo, gestionando políticas de seguridad (autenticación y permisos), control de tráfico y transformación de datos.\nGCP: implementar la carga y gestión de archivos en Google Cloud Storage, la persistencia en Cloud SQL (PostgreSQL) y la mensajería con Cloud Pub/Sub.\nCalidad y observabilidad: escribir pruebas automatizadas unitarias y de integración, y monitorear el rendimiento y la trazabilidad de las transacciones con Elastic APM.\nEntrega incremental: dividir el trabajo en entregas funcionales y continuas, usando herramientas de IA para agilizar la codificación, la refactorización y las pruebas.\nValoramos positivamente\nDesarrollo asistido por IA: uso habitual y crítico de asistentes de código e IDEs con IA para codificar, refactorizar, generar pruebas y documentar. Mentalidad de entrega incremental: criterio para diseñar arquitecturas evolutivas, con despliegues continuos de incrementos estables y probados. Experiencia en el sector financiero.\nCondiciones\nUbicación: Santiago, Chile. Modalidad: híbrida. Contrato: plazo fijo, 3 meses.","description_format":"text","description_chars":4064,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Consulting & Digital Transformation"],"lifecycle":[{"event":"open","at":"2026-10-30T22:02:00Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":2,"expected_fill_days":14,"reasons":["seen:2","velocity","win:early"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/factor-it-back-end-developer-senior-java-25-spring-boot-3","json_url":"https://alion.io/job/factor-it-back-end-developer-senior-java-25-spring-boot-3.json","meta":{"generated_at":"2026-11-02T06:19:31Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":9119,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3852494},"rest":"https://alion.io/mcp/rest/get_company?id=3852494"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffactor-it-back-end-developer-senior-java-25-spring-boot-3"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Ffactor-it-back-end-developer-senior-java-25-spring-boot-3"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Ffactor-it-back-end-developer-senior-java-25-spring-boot-3"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/factor-it-back-end-developer-senior-java-25-spring-boot-3\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffactor-it-back-end-developer-senior-java-25-spring-boot-3"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3549404}},{"tool":"search_jobs","arguments":{"company":"factorit.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3549404},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
