Job Description

Senior Applied AI Engineer

ultima milla

• Diseñar y construir sistemas de IA en producción que resuelven problemas reales de negocio, end-to-end: desde discovery hasta operación. • Trabajar con producto y operaciones para traducir problemas ambiguos en soluciones acotadas, medibles y mantenibles. • Construir pipelines de datos que alimentan tanto modelos como superficies de producto. • Diseñar sistemas de evaluación rigurosos: cómo medimos calidad, cómo detectamos regresiones, cómo decidimos cuándo algo está listo para shippear. • Integrar LLMs en producción con todos los retos que eso implica: prompt engineering serio, tool use, manejo de costos y latencia, control de calidad de outputs. • Tomar decisiones técnicas sobre qué tipo de solución aplicar a cada problema. No todo necesita un LLM, no todo necesita ML, y parte del rol es saber distinguir. • Diseñar e implementar las salvaguardas de seguridad del sistema: límites de autonomía, aprobaciones humanas, aislamiento entre clientes, auditoría. • Colaborar con el equipo de backend para definir contratos e integraciones limpias entre servicios. • Mentorear a otros ingenieros en prácticas de IA aplicada conforme el equipo crezca (responsabilidad creciente con el nivel de seniority).

Job Requirements

  • Inglés B2 o superior.
  • +6 años de experiencia total, con más de 3 años trabajando en sistemas de ML/IA en entornos productivos.
  • +4 años de experiencia en ingeniería de software, incluyendo al menos 2 años desarrollando y manteniendo sistemas de Machine Learning o IA en producción (más allá de notebooks o pruebas de concepto).
  • Experiencia práctica construyendo sistemas con LLMs en producción: prompt engineering serio, function calling / tool use, RAG, manejo de costos y latencia, evaluación de outputs.
  • Sólido conocimiento de al menos un lenguaje fuerte para sistemas de IA — Python es el más común, pero también consideramos perfiles fuertes en Go, Rust o TypeScript/Node siempre que tengas experiencia construyendo sistemas de ML/IA productivos en ese stack.
  • Experiencia con al menos un framework de ML (PyTorch, scikit-learn, JAX, o equivalente).
  • Capacidad de tomar un problema de producto ambiguo y traducirlo en un sistema de IA acotado, medible y mantenible.
  • Mentalidad de evaluación primero: sabes que un sistema de IA sin métricas no es un sistema, es una apuesta.
  • Experiencia diseñando pipelines de datos a escala (sistemas de mensajería event-driven, procesamiento batch, o equivalente).
  • Has liderado al menos un sistema de IA end-to-end en producción, desde discovery hasta operación.
  • Experiencia con observabilidad de sistemas de IA: tracing distribuido, métricas de calidad, detección de drift.
  • Capacidad demostrada para influir en decisiones arquitectónicas que cruzan equipos.
  • Experiencia evaluando y eligiendo entre modelos, proveedores, y arquitecturas (cuándo fine-tuning vs prompting vs modelo clásico, cuándo un proveedor comercial vs open source, cuándo agentes vs pipelines).
  • Mentoría formal de otros ingenieros de IA y definición de prácticas de equipo.
  • Capacidad para comunicar trade-offs técnicos a audiencias técnicas y no técnicas, en español e inglés.

Benefits

  • Misión a nivel regional: lograr que los negocios de LATAM se despreocupen de su logística.
  • Ubicación: Argentina, Colombia, México, Venezuela, Panamá, Perú.
  • Esquema: 100% remoto.
  • Horario: Lunes a Viernes 8:00 a 17:00 CST (México).
  • Con flexibilidad de horario cuando haya nuevos releases.
  • Crecimiento y desarrollo profesional.
