• Connecting the platform to customers' systems: CRMs, ticketing, calendars, internal APIs and their phone setup.
• Writing integration code and small services in Python or TypeScript.
• Debugging live calls with customers: reading logs and traces, finding the cause, fixing it or handing it to the core team with a clear report.
• Turning what you learn on site into product improvements, together with engineering.

Technical Skills:

Required:

• Solid Python or TypeScript; REST APIs, webhooks and authentication.

• Docker, cloud platforms, CRM platforms such as HubSpot or Salesforce.

Communication:

Soft Skills:

• Flexible Work Setup: Work fully remotely or from a co-working space — whichever suits you best.
• Equipment Provided: Company laptop and phone provided for all employees.
• Collaborative Environment: Join a small, agile team where your contributions have a direct impact.
