ABOUT Wonderful

Wonderful enables enterprises to build, test, deploy, and monitor AI agents for their most complex needs, serving customers and employees seamlessly across voice, chat, email, and back-office systems in any language or cultural context.

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
