What you will do

• Design and implement integrations with cutting-edge Large Language Models (LLMs) and APIs (like OpenAI’s models, Anthropic’s Claude, and more).
• Develop intelligent, agent-based systems to automate and assist in complex software development tasks.
• Engineer the core infrastructure for our AI agents, including components such as 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.

This is a greenfield project, which means you’ll have a say in the technologies we choose. Nothing is set in stone. However, our environment and the problem space suggest we’ll be working with:

Primary Languages: Python, TypeScript, Scala – based on available APIs and existing integration – but actual stack will be determined as the project progresses. The project will be based on internally developed services and solutions, utilising Scala, Java, AWS, GRPC, MySQL and more.

What we expect:

• Proven polyglot programming skills with the ability to rapidly learn new languages, frameworks, and domains
• Strong, hands‑on experience in Python
• Hands‑on, practical experience building with or integrating LLMs, coding assistants, or AI agents. You should be ready to demonstrate your work or discuss your implementation experience during the interview
• A proactive, self‑starter attitude. You take initiative, communicate clearly, and thrive in a collaborative, goal‑oriented environment
• 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 (we are not looking for model researchers or trainers)

A few perks of being with us

• Building tech community
• Home office reimbursement
• Training Package
• And a lot more!
