  • Integrate Mo with all Alan services
  • Extend our architecture to support the next chapters of Mo

Requirements:

  • Strong background in software engineering, systems architecture, with a spike in back-end engineering
  • Experience with traditional ML, or LLMs, or ML dev ops is a big plus
  • Product-minded: you want your solutions to be used, and impactful

  • Humble and still willing to grow (no matter your seniority!)
  • Collaborative, enthusiastic about teamwork, learning, and teaching
  • Fluent in English (no need to speak French!)
  • High potential and curiosity
  • 5+ years of experience
What we offer:
  • Fair rewards. Generous equity packages complement your base salary
  • Flexible Office. Amazing office space at our HQ, sponsored co-working hubs or a full-remote experience with home office equipment sponsorship
  • All the tools you need. Top of the range equipment: Macbook Pro, keyboard, laptop stand, monitor, and noise-canceling headphones
  • Flexible vacation policy and flexible working hours
  • Delightful healthcare insurance: Extremely comprehensive health insurance - 100% for you and your children, 90-100% for partners depending on your country (permanent contracts only)
  • Transport. Country-specific commuter benefits
  • Learning & Training opportunities. A highly flexible Training policy free books and budget to attend and speak at conferences if the opportunity arises
  • Personal growth through coaching: At Alan, coaching isn't just a perk - it's core to who we are. Every Alaner is paired with a dedicated coach from day one
