ABOUT Wonderful

Role Overview:
  • Lead the technical side of sales: join early-stage conversations, present demos, and guide architecture and security discussions.

  • Act as hands-on engineering lead - shipping code, building integrations, and setting high quality standards.

  • Build and lead a high-performing technical team across engineering, integration, and pre-sales.

  • Drive customer integrations, from scoping to deployment of AI agents, and ensure production accuracy.

  • Gather customer feedback, localize the product, and represent regional needs to the global Product team.

  • Serve as the local technical point of contact, building partnerships and handling escalations.

  Requirements:
  • 8+ years of hands-on software engineering experience - you’ve built things that actually shipped

  • Proven track record in pre-sales, solution architecture, or complex technical implementations

  • Customer-facing background in roles like Site CTO, Solutions Architect, or Deployed Engineer - you know how to speak both tech and business

  • Strong leadership DNA - ideally with Founder experience

  • Excellent English (written and spoken) plus fluency in at least one local language

  • Comfortable operating independently in a zero-to-one environment - building the plan, the team, and the system from scratch

  • Experience thriving in a fast-moving startup where speed and ownership matter more than titles
