Full-Stack Engineer (Back-End Leaning)

The role

This position sits within the engineering organisation and centres on server-side work for a voice AI company's product suite. The engineer would staff projects across the business, building features on top of the company's speech models, extending customer-facing products, and keeping internal systems reliable as usage grows. Collaboration with frontend, growth, and sales colleagues is part of the day-to-day.

What you would do

• Build and operate the platform layered over the company's voice models, which serve a very large user base
• Extend existing products with meaningful new capability and third-party or enterprise integrations
• Strengthen internal infrastructure so services stay available, fast, and secure during scaling
• Partner with frontend, growth, and sales teams to shape solutions for customers
• Move between projects across the company based on current priorities

What they asked for

• Strong proficiency in Python
• Solid track record in back-end development
• Understanding of common system design approaches and infrastructure, including API design, cloud tooling, storage, and data structures
• Working knowledge of test design and security fundamentals
• Formal credentials are not required; evidence of hard problems solved, such as projects or open-source contributions, carries weight

Nice to have

• Hands-on experience with container orchestration via Kubernetes
• Experience integrating Stripe or comparable payment providers
• Grounding in how AI models function
