ML Engineer

A Foundational Company

Rilla builds the world’s leading conversation intelligence software for offline commerce.

By recording, analyzing, and indexing conversations, our platform supplies unparalleled alpha to the critical, physical businesses that constitute the backbone of our economy.

Our purpose is to bring the technology of the 21st century’s most innovative companies to the rest of the economy.

As a side effect of this mission, we’ve become one of the fastest growing companies in history. In numbers, that means 0→$40M in 3.5 years, growing 15% MoM, Net Revenue Retention above 170%, an NPS higher than the iPhone’s, and profitability.

The Role

ML Engineers at Rilla are redefining how humans interact with machines—using voice, intelligence, and a whole new class of data.

Every day, you’ll architect and ship AI-powered systems that make it possible for people to talk to Rilla like they would a human. You’ll help build agents that operate natively on real-world audio, extract insights from conversations no one else can even access, and push the boundaries of what’s possible in AI.

We’re building:

• A voice-first interface that lets users command Rilla directly through natural speech

• A search engine that uncovers business-critical insights from voice data that’s never been searchable

• A first-of-its-kind audio intelligence pipeline—designed for the messy, noisy, wildly unstructured conversations that happen in the real world, not in an online meeting

As an early ML engineer, you’ll shape the foundations of our AI stack and drive the invention of new techniques, tooling, and models. You’ll work across the full AI lifecycle—from data acquisition to real-time inference and user-facing chat interfaces.

If you’re obsessive about your craft, think like a founder, and want to be on the frontier of voice and offline AI, this is your team. The scale of the problems we’re solving is unmatched—and the surface area for ownership is only getting bigger.

Technologies We Use

• We work primarily in Python and TypeScript, with FastAPI for API development

• AI/ML technologies including PyTorch, OpenAI APIs, Baseten, and LiteLLM

• Cloud infrastructure with AWS and LiveKit for real-time communications

• PostgreSQL, Redis, and S3 for data storage

What We Value

• An infinite learner. Someone who is relentless in their curiosity.

• A customer obsessive. Someone who deeply care about delighting customers and solving real pains, not vanity metrics.

• A winning attitude. You thrive with extreme accountability, learning as a team, and both giving and receiving rapid feedback.

• Extreme empathy. Our customers are not tech companies. They live and work in the real world. Empathy is critical to arriving at correct solutions.

• Unafraid of failure. You take risks. You see failure as an opportunity to learn, grow, and be better the next time. In a weird way, you trick your brain into being excited when you fail, because it means you got a new opportunity to learn more.

What We Require

• Experience building and deploying ML systems in production

• Familiarity with owning the model lifecycle from inception to production.

• Comfort working directly with customers to understand their needs and solve real-world problems
