Job Title: Backend Engineer
Company Description: Proveden Ltd - London-based voice AI startup building real-time interpretation infrastructure.
Job Description:
Join as the second backend engineer to build production-grade infrastructure for real-time voice interpretation. Working directly with the technical founder, you will own the core API platform that enables instant, tonally-accurate translation across multiple languages. You will architect scalable systems for high concurrency, ensuring natural, fluid conversations for global users.
Location: London, UK
Why this role is remarkable:
Ownership of a build-from-scratch opportunity where you design the core infrastructure rather than maintaining legacy systems.
Work on cutting-edge voice AI that preserves tone and intent, solving the complex challenge of real-time, low-latency cross-language interpretation.
Join a high-autonomy, technical founding team at a critical scaling phase with a functional product already in use.
What you will do:
Design and build a unified AI API platform to package internal capabilities into a scalable, production-ready system.
Architect and manage high-concurrency infrastructure, including real-time voice rooms, auto-scaling, and load balancing on Azure.
Implement critical business logic systems including usage metering, billing pipelines, and comprehensive monitoring/analytics dashboards.
The ideal candidate:
4-8 years of backend experience with a proven track record of building and scaling production systems from the ground up.
Expert-level Python skills with deep knowledge of distributed systems, cloud infrastructure, and database optimization.
Experience with real-time systems or voice technologies, paired with a strong ownership mindset to thrive in a small, fast-paced team.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
