Wonderful is transforming the way enterprises deliver customer support, blending cutting-edge AI with local market expertise.

• Integrate our AI platform with customer systems, APIs, and workflows
• Design and implement backend services and data pipelines to support integrations
• Build, configure, and deploy AI agents tailored to specific customer use cases
• Collaborate directly with customers to understand requirements and deliver custom solutions
• Serve as a trusted technical contact for customer-facing teams
• Troubleshoot, debug, and optimize integrations in real-world environments
• Work closely with internal product and R&D teams to align customer needs with platform capabilities

• 4–5+ years of software development experience, including production-grade backend systems
• Strong proficiency in TypeScript and Go
• Solid understanding of HTTP, REST APIs, and modern web integration patterns
• Hands-on experience working with AI agents and integrating LLMs into real-world applications
• Comfortable navigating cloud environments and shipping fast across the stack
• Excellent communication skills and confidence working directly with customers
• Problem-solver mindset with a high degree of autonomy and adaptability

Bonus Points

• Experience in early-stage startups or fast-paced product teams
• Familiarity with cloud infrastructure (AWS, GCP) and containerized deployments (Docker, Kubernetes)
• Understanding of vector databases, embedding models, or retrieval systems

• A seat at the table as we build a new AI category from the ground up.
• The energy of an early-stage scale-up + the stability of world-class investors.
• Ownership, autonomy, and impact that you just won’t find at corporate giants.
• A team of ambitious builders who balance urgency with a strong sense of vibe.
