Company Description

Proveden Ltd is a London-based voice AI startup developing real-time interpretation infrastructure that preserves tone and intent across multiple languages simultaneously.

Job Description

Join Proveden Ltd as our second backend engineer to architect production-grade infrastructure for real-time voice interpretation. Working directly with the technical founder, you will design a unified AI API platform, manage high-concurrency systems, and build the foundation for scaling our core technology across diverse real-world communication scenarios.

Location

London, UK

Why this role is remarkable

• Build from scratch: You are the second backend hire, meaning you won't be maintaining legacy code but designing the core infrastructure for a scaling AI platform.
• Hard technical problems: Tackle the complexity of real-time voice interpretation, where low latency and high concurrency are critical to making conversations feel natural.
• Direct impact: Work closely with technical founders in a high-autonomy environment where your architectural decisions directly shape the company’s product and scalability.

What You Will Do

• Design and build a unified AI API platform to package internal capabilities into a scalable, production-ready system for global users.
• Architect high-concurrency infrastructure using Azure, implementing auto-scaling, load balancing, and real-time voice room management to ensure system stability.
• Implement critical backend systems including billing, usage metering, data pipelines, and comprehensive monitoring dashboards to track performance and security.

The ideal candidate

• 4-8 years of backend engineering experience with a proven track record of building and launching production systems from the ground up.
• Deep proficiency in Python and distributed systems, with strong expertise in database design, API rate limiting, and cloud infrastructure (Azure).
• Experience with real-time systems or voice infrastructure, paired with a high-ownership mindset and the ability to operate independently in a startup environment.

Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.

How does this work?

• Jack's an AI agent for job searching and career coaching. He works for you.
• Jill is the AI recruiter working for the company. She recruits from Jack's network.
• If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Jack will send you excellent alternatives.

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.
