Título profesional en Ingeniería de Sistemas, Ciencias de la Computación, Ingeniería Electrónica o afines.\n\nEl propósito del rol es desarrollar, probar y mantener el código de las canalizaciones (pipelines) de datos en tiempo real que ingieren telemetría desde sistemas industriales (SCADA, historiadores y sensores), asegurando que los datos fluyan continuamente desde la planta hasta los sistemas analíticos mediante transformaciones de baja latencia y sin degradación de rendimiento.\n\nRequisitos del perfil:\n\nExperiencia: Sólida trayectoria en ingeniería de datos y desarrollo de software \"hands-on\", procesando datos en streaming e integrando sistemas industriales (OT-IT). Experiencia comprobable gestionando formatos típicos de telemetría de campo (Timestamp, Tag/Sensor ID, Value, Quality Flag).\n\nLenguajes y Bases de Datos: Nivel avanzado en Python (asyncio, FastAPI) y SQL (agregaciones por ventanas, particionamiento de series temporales). Nivel intermedio/avanzado en Java o Scala. Dominio técnico en bases de datos de series temporales (ClickHouse, TimescaleDB o InfluxDB) y optimización de consultas INSERT.\n\nStreaming y Conectividad SCADA: Uso intensivo de Apache Kafka (APIs, conectores) y motores como Flink o Spark Streaming. Experiencia conectando servidores SCADA e historiadores (Ignition, PI Web API) mediante OPC UA, Modbus y MQTT. Implementación de serialización (Avro/Protobuf) y Schema Registry.\n\nCompetencias: Perfil 100% ejecutor orientado al código limpio. Capacidad analítica para depurar problemas de rendimiento (cuellos de botella, lag, backpressure). Dominio de entornos Linux, Docker, Git y flujos CI/CD.\n\nFunciones principales:\n\nEscribir aplicaciones de procesamiento en streaming para transformar y enriquecer datos industriales continuos; construir servicios livianos para conectarse a servidores SCADA y gateways IoT; desarrollar la lógica de inserción masiva por micro-lotes hacia bases de datos y datalakes; resolver problemas diarios de rendimiento en producción; y ejecutar pruebas unitarias para validar lógicas de agregación y el manejo de datos que llegan fuera de orden (watermarking).\n\nModalidad: Remoto\n\nContrato: Indefinido","description_format":"text","description_chars":2292,"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":[{"name":"Colombia","iso":"CO","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-11-09T15:56:30Z"}],"visa":[],"liveness":{"score":62,"band":"ok","label":"Likely open","p_open":0.85,"p_active":0.81,"p_room":0.9,"age_days":14,"expected_fill_days":27,"reasons":["seen:14","win:mid"],"computed_at":"2026-11-09T19:21:14Z"},"pay":null,"html_url":"https://alion.io/job/octans-digital-services-java-developer","json_url":"https://alion.io/job/octans-digital-services-java-developer.json","meta":{"generated_at":"2026-11-09T19:21:14Z","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":5052,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-10T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":4527125},"rest":"https://alion.io/mcp/rest/get_company?id=4527125"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Foctans-digital-services-java-developer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Foctans-digital-services-java-developer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Foctans-digital-services-java-developer"},{"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/octans-digital-services-java-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Foctans-digital-services-java-developer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3971245}},{"tool":"search_jobs","arguments":{"company":4527125,"detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3971245},"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.
