Astrix builds conversational AI simulations that help organisations develop and measure human skills like leadership, communication, and decision-making — skills that traditional training struggles to evaluate.

• Competitive salary
• Opportunity to work deeply with:
  • Agentic AI
  • Conversational AI
  • Real-time systems used by enterprise clients

Who Thrives at Astrix

The kind of engineer who thrives here is someone who:

• Is a self-starter and doesn’t need micromanagement
• Is disciplined about milestones and deadlines
• Communicates clearly and proactively
• Is comfortable owning problems end-to-end
• Enjoys building real products used by real people
