  • Engineer the core infrastructure for our AI agents, including components like MCP servers
  • Seamlessly weave AI capabilities into the daily workflows of our developers by integrating with essential tools like GitHub, Slack, IDEs, and client internal services, mostly Scala-based
  • Collaborate within a distributed, international team to research, prototype, and deploy solutions that have a direct impact on developer productivity and satisfaction

Requirements:

  • Proven polyglot programming skills with the ability to rapidly learn new languages, frameworks, and domains
  • Hands-on, practical experience building with or integrating LLMs, coding assistants, or AI agents
  • Strong, hands-on experience in at least one of the following: Scala, or another modern JVM language (e.g., Kotlin, Java 17+)
  • A proactive, self-starter attitude
  • Excellent communication skills in English and the ability to effectively collaborate with team members in the US West Coast time zone

Nice to have:

  • A passion for or prior experience in building developer tools, IDE plugins, or enhancing developer workflows
  • Experience with DevOps practices and tools (CI/CD, Docker, Kubernetes, cloud platforms like GCP or AWS)
  • Familiarity with the MLOps or Data Engineering ecosystem, particularly on the integration and tooling side
What we offer:
  • Building tech community
  • Flexible hybrid work model
  • Home office reimbursement
  • Language lessons
  • MyBenefit points
  • Private healthcare
  • Training Package
