  • • Work in a hybrid model requiring 3 days per week in the Paris office (Monday mandatory), with flexibility for remote work and quarterly remote weeks.

🎯 Requirements

  • • 5+ years of professional software engineering experience with strong proficiency in backend development using Python (FastAPI, Django, or similar frameworks) and/or Golang.
  • • Hands-on experience with frontend technologies including VueJS, TypeScript, and modern JavaScript frameworks, preferably in a Nuxt or SPA context.
  • • Proven ability to design, build, and maintain distributed systems using PostgreSQL, Redis, Kafka, or RabbitMQ, with familiarity in event-driven architectures.
  • • Experience working with cloud infrastructure (GCP preferred), Kubernetes, Docker, and CI/CD pipelines (CircleCI, ArgoCD, or similar).
  • • Demonstrated ownership mindset, strong communication skills, and fluency in English for collaboration across global teams.
  • • Experience in agile environments with a track record of improving system reliability, observability, or performance through initiatives like chaos engineering or SLA-driven development.

🏖️ Benefits

  • • Hybrid work model: 3 days/week in Paris office (Monday mandatory), 2 remote days weekly, plus 1 remote work week per quarter and 3 flex days annually.
