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
