Backend Team Lead (ML)

Mayflower is a technology company building highload products used by millions of people worldwide. Operating at the scale of one of the world's top-50 websites, we solve complex engineering challenges and create solutions that power real-time entertainment for a global audience.

We are looking for a Backend Team Lead for our ML development team focused on building and delivering production-grade ML-powered applications.

This role is not about research or experimentation. You will be responsible for turning ML models into reliable, scalable, user-facing services.

You will work at the intersection of machine learning and backend engineering, owning the full lifecycle of ML-powered features — from integration to deployment and operation in production.

Job Responsibilities

Design and build production ML services (APIs, microservices, real-time systems)

Lead and grow a team of backend engineers: plan work, mentor team members, conduct code reviews, provide technical guidance, and foster engineering excellence.

Drive architectural decisions and ensure the scalability, reliability, and maintainability of ML services.

Integrate ML models into user-facing applications

Ensure reliability, scalability, and performance of ML-powered systems

Define and implement best practices for serving, versioning, and monitoring models in production

Collaborate closely with:

ML engineers / data scientists (who develop models)

DevOps / MLOps team (who provide platform and infrastructure)

Own the delivery pipeline of ML features into production

Lead and mentor engineers working on ML-powered applications

Drive architectural decisions around low-latency and high-load systems

Identify bottlenecks between experimentation and production and eliminate them
