Algunos de nuestros clientes incluyen Uber, Instacart, Doordash, Netflix, Compass Group y Adecco.

Una carrera en Checkr es una oportunidad para trabajar con algunas de las mentes más brillantes, transformar una industria para un futuro mejor y dar acceso al empleo a candidatos que de otro modo serían ignorados. Checkr ha sido reconocida en la lista de Forbes de los mejores empleadores de startups y es una de las principales empresas de Y Combinator por valoración.

Únete al equipo de IT Engineering como Senior Integrations & AI Engineer, donde desempeñarás un papel vital en la mejora de la productividad de los empleados en todos los departamentos de Checkr. En este rol, diseñarás, construirás y mantendrás integraciones empresariales que conectan nuestros sistemas de negocio críticos, actuando también como un socio de confianza para los equipos internos que dependen de ellos. Irás más allá de la ejecución pura, ayudando a los stakeholders a articular sus necesidades, definiendo el alcance de los requerimientos y utilizando tu influencia para lograr la alineación entre prioridades en competencia. A medida que nuestras funciones de integración e IA convergen, aportarás fluidez en IA para identificar oportunidades donde tecnologías como los Modelos de Lenguaje Extensos (LLMs) y la Generación Aumentada por Recuperación (RAG) puedan hacer que los flujos de trabajo sean más inteligentes y eficientes.

Lo que harás:

• Impulsar requisitos y alineación de stakeholders: Colaborar con socios internos de diversos departamentos para descubrir necesidades de forma proactiva, hacer las preguntas correctas y traducir problemas de negocio en especificaciones técnicas claras. Usar tu influencia para ayudar a los equipos a priorizar y establecer expectativas realistas.
• Construir integraciones empresariales: Diseñar, desarrollar y desplegar integraciones utilizando plataformas iPaaS (principalmente Tray.io) para conectar sistemas críticos como Salesforce, Workday, Zendesk, Snowflake y otras aplicaciones corporativas.
• Colaboración interfuncional: Trabajar estrechamente con ingenieros, sistemas de negocio y producto para alinear el trabajo de integración con iniciativas técnicas más amplias. Servir de puente entre los interesados no técnicos y los equipos técnicos.
• Optimización de la plataforma: Liderar esfuerzos para consolidar y optimizar nuestro ecosistema de plataformas de integración, garantizando escalabilidad, fiabilidad y rentabilidad.
• Aplicar IA donde agregue valor: Identificar oportunidades para mejorar los flujos de trabajo utilizando tecnologías de IA (LLMs, procesamiento de lenguaje natural y RAG) para pasar de una sincronización de datos básica hacia soluciones adaptativas e inteligentes.
• Iterar y mejorar: Recopilar comentarios sobre las soluciones de integración, refinándolas continuamente según las necesidades de los usuarios y las nuevas capacidades tecnológicas.
• Documentación y transferencia de conocimiento: Crear y mantener documentación clara y runbooks que reduzcan la dependencia de miembros individuales del equipo.
• Planificación estratégica: Contribuir a los roadmaps de integración e iniciativas de IA alineadas con los objetivos organizacionales.
• Mantenerse al día con las tendencias: Investigar los últimos avances en plataformas iPaaS y AI/ML, compartiendo hallazgos con el equipo.

• Sólidas habilidades de programación en al menos un lenguaje de scripting (Python, JavaScript o Ruby) con capacidad para escribir código personalizado dentro de los flujos de integración.
• Más de 3 año de experiencia en proyectos de AI/ML, incluyendo la construcción de soluciones potenciadas por IA, trabajo con LLMs o implementación de arquitecturas RAG.
• Experiencia con MCP, construcción de agentes, automatización agente-a-agente y otras tecnologías de IA relacionadas.
• Familiaridad con plataformas en la nube (AWS, Azure o GCP) es un plus.
• Sólido conocimiento de diseño de APIs, servicios RESTful, webhooks y arquitecturas orientadas a eventos.
• Experiencia con aplicaciones SaaS empresariales y bases de datos (Salesforce, Workday, Zendesk, Snowflake, etc.).
• Capacidad excepcional para abordar problemas abiertos en entornos no estructurados, sintetizando requisitos complejos en soluciones técnicas escalables.
• Historial comprobado de trabajo efectivo en equipos multidisciplinarios, con fuertes habilidades interpersonales y de comunicación.
• Atención al detalle con compromiso por la calidad del código, la documentación y la excelencia operativa.
• Un profundo interés en aprovechar tanto los patrones de integración tradicionales como las tecnologías de IA para transformar procesos internos.
