  • Build scalable, low-latency, and fault-tolerant systems to serve recommendations at scale
  • Develop robust APIs and services to deliver real-time or batch recommendations (using Python, Go)
  • Integrate ML models into backend services and production applications
  • Optimize performance of model inference systems (e.g., using vector databases, caching, distributed serving)
  • Build and maintain CI/CD pipelines for model and service deployment
  • Leverage modern monitoring/telemetry tools to identify, assess, and provide solutions to platform issues
  • Stay up to date with the latest technology trends and bringing the best to the team

Requirements

  • 5+ years of experience in machine learning and backend software engineering
  • Strong experience building recommendation systems in a real-world production setting
  • Proficiency in at least one backend programming language (e.g., Go, Java) and Python
  • Deep understanding of recommendation algorithms, user modeling, embeddings, and similarity search
  • Experience with ML pipeline tools (e.g., MLflow, Kubeflow, Airflow)
  • Familiarity with serving architectures (e.g., REST/gRPC APIs, model servers)
  • Strong grasp of distributed systems, microservices, and system design
  • Experience with SQL and NoSQL databases and working with large-scale datasets

Nice to have

  • Experience with real-time recommendations (e.g., using Kafka, Redis, or Pub/Sub systems).
  • Experience with personalization strategies, ranking models, or reinforcement learning.
  • Exposure to experimentation platforms and online A/B testing.

We offer

  • Flexible working hours (full-time).
  • One "Flex Day" off per month – eligible after six months with the company.
