About the Role Si desea conocer los requisitos para este puesto, siga leyendo para obtener toda la información relevante.We are seeking a Senior GEN?AI Engineer with a Data & Platform focus. You will design, build, and operate GEN?AI powered, data?intensive systems that process and learn from large?scale event streams. This role is production?oriented: you’ll ship reliable LLM features, prove they work via rigorous evaluation, and continuously improve quality through context engineering.This is not a research?only role. You will work on systems where LLMs interact with business?critical workflows, and where quality, latency, observability, and operational reliability matter.What you can expect:Build and maintain production?grade GEN?AI services in Python.Write clean, maintainable, and efficient code.Optimize applications for performance, reliability, and scalability.Design systems that process, enrich, and learn from real?time event streams.Work with data pipelines, message queues, retrieval systems, and streaming architectures.Build reliable context and retrieval layers for LLM?powered products.Improve LLM quality through context engineering, evaluation, observability, and feedback loops.Design systems with idempotency, retries, deduplication, backpressure, and failure recovery in mind.Collaborate closely with backend, data, product, and infrastructure teams.What we are looking for:Bachelor’s degree in Computer Science, Engineering, or a related field.1+ years of experience with GEN?AI projects.5+ years of experience with the Python programming language.Proven experience building data?intensive applications.Hands?on experience shipping production systems, not only prototypes or notebooks.Experience with event?driven systems, message queues, or streaming architectures.Experience with Kubernetes or cloud?native infrastructure.Strong understanding of observability, metrics, logging, alerts, and production debugging.Ability to reason about reliability topics such as idempotency, retries, duplicate events, backpressure, latency, and failure modes.Experience with distributed systems, including design patterns for scalability, fault tolerance, data consistency, and partitioning in large?scale production environments.Experience with data retrieval techniques.Experience with DSPy, GEPA, or other LLM optimization/evaluation techniques is a plus.Experience with some of the following is a strong plus:RisingWave or other streaming databasesApache Kafka or similar event?streaming systemsApache Iceberg, data lakes, lakehouse architectures, or Ice Lake?style platformsAirflow or similar workflow orchestration toolsPostgreSQL or other relational databases at scaleVector databases or hybrid searchReal?time data processingData retrieval systemsOur offer to youCompetitive salary based on performance and experienceChance of earning Klar stock options26 days of paid vacation per yearComputer deviceInternational work environment with amazing and highly skilled peopleA world class team that helps you evolve your skills in areas you’re interested inWellhub subscription to offer mental and physical healthKlar is a safe place for everyone!We trust our highly skilled and diverse team and we’re committed to creating a welcoming and inclusive environment for new talents to flourish.
