  • Hands-on expertise in fine-tuning large language models and applying post-training methods such as SFT and RLHF in real-world settings
  • Strong proficiency in Python and SQL; familiarity with TypeScript is beneficial
  • Experience with version control, automated testing, and CI/CD pipelines
  • Ability to communicate complex technical concepts across research and engineering teams
  • Proven success in mentoring research teams on engineering best practices and production workflows
  • Comfort operating in fast-moving, uncertain environments while upholding high standards for quality and safety

Benefits

  • Remote work flexibility with a preference for candidates in London, Lisbon, or Porto
