  • Quality & DevOps: Write comprehensive unit and integration tests; maintain CI/CD pipelines; perform code reviews and enforce best practices.
  • Cross-Functional Collaboration: Partner with ML engineers, product managers, and analysts to define requirements and deliverables.
  • Documentation & Monitoring: Create clear API documentation, system diagrams, and runbooks; implement monitoring and alerting for critical workflows.
  • Front-End Support (Bonus): Develop simple dashboards or tooling to visualize model outputs, metrics, and pipeline health.

Qualifications

  • 5 years of professional software development experience focusing on backend systems.
  • Expert-level Python skills; strong coding ability in application development.
  • Exposure to statistics, mathematics, and machine-learning concepts.
  • Experience building data pipelines or evaluation frameworks for ML/LLM workloads.
  • Proficiency with testing frameworks, CI/CD tools, and code-review processes.
  • Solid collaboration and communication skills in agile environments.

Nice-to-Haves

  • Hands-on experience with large language models or advanced AI frameworks.
  • Familiarity with cloud platforms (AWS, GCP, or Azure) and containerization (Docker, Kubernetes).
  • Prior experience in startups or fast-paced tech settings.
  • Backend expertise in microservices, RESTful APIs, and database technologies.
