Open roles
Full Stack JavaScript Developer — AI Agents & DevOps
We're looking for a Full Stack JavaScript Developer with a strong inclination toward the new frontiers of software development: AI agent development, vibe coding with next-gen tools, and solid DevOps skills.
The ideal candidate is someone who doesn't just write code, but orchestrates intelligent systems, automates pipelines, and leverages AI-native tools to multiply their own productivity and the team's. You'll play an active role in shaping the technical architecture of our products, with a key role in the development of the Compass platform and other strategic projects.

- Experiment with and integrate new AI-native development paradigms into the team's daily workflow
- Contribute to defining best practices and internal workflows for vibe coding and assisted development
- Evaluate and rapidly prototype new tools and frameworks emerging in the AI/dev ecosystem
04 · DevOps & Infrastructure
- Manage cloud infrastructure on AWS, GCP or Vercel/Railway with an Infrastructure as Code approach (Terraform, Pulumi, SST)
- Configure and maintain CI/CD pipelines (GitHub Actions, GitLab CI) with automated deployments
- Containerize applications with Docker and orchestrate with Kubernetes or managed solutions
