  • Significant, demonstrated impact that your work has had on the product and/or the teams.
  • Deep knowledge of a high-level programming language (for example, Ruby, Python, Perl etc.) but it doesn’t need to be a language that we use here; great people are effective and learn what we use quickly or introduce us to better ways of working.

  • Provide assessments of project progress, risks and challenges to engineering leadership to help guide resource allocation and prioritisation.
  • Contribute to our technical architecture as we grow.
  • Care about agility as much you care for scalability and availability. Continuous deployment keeps us focused on incremental releases. Even our biggest technical achievements roll out piece by piece, feature flagged out of sight.
  • Contribute to all phases of software development including ideation, prototyping, design and implementation. This role has a mix of both hands-on development as well as lead/architecture work.
  • Build using the best tools in the industry. We invest heavily in AI-powered developer tools that remove friction and help you focus on solving meaningful problems.
  • Play an active role in hiring, mentoring and career development of other engineers
  • Raise the bar for technical standards, performance, reliability, and operational excellence

What believers are saying

  • Fin for Platforms expansion into Zendesk and competitor ecosystems diversifies revenue beyond native platform.
  • 350+ third-party integrations including Salesforce and Stripe increase switching costs and cross-sell opportunities.
  • Proactive support and outbound messaging tap growing demand for customer retention and churn prevention.

What critics are saying

  • Zendesk Answer Bot and Salesforce Service Cloud Einstein AI erode market share with native AI integration.
  • Fin standalone agent on Zendesk cannibalizes core platform revenue as customers adopt AI separately.
  • Venture debt at 12-15% interest rates trigger cash burn crisis amid slowing AI growth.

What makes Intercom unique

  • Fin AI agent resolves 50% of queries automatically with multilingual, multi-channel action capabilities.
  • Omnichannel consolidation across email, chat, phone, WhatsApp, and social apps in single inbox.
  • Real-time customer intelligence combining behavioral data, conversation history, and custom attributes.
