Backend Department

Join us as a Backend Department Lead and drive the technical direction and development of the backend platform behind one of the fastest-growing AI products in the US market.

We are looking for a strong technical leader who combines deep expertise in high-load system architecture with hands-on engineering leadership and experience in building and developing high-performing backend teams. In this role, you will have real technical ownership of our AI Gateway, generative pipelines, and mission-critical backend services powering a product already used by more than 2 million people.

About Us:
Zeely is the agentic AI platform for creating, launching, and scaling paid ads.

Simply put: we've made the best AI solutions and marketing tools available to small and medium businesses — tools that used to be reserved for big brands with expensive marketing teams.

The next big step: a B2B solution for large marketing teams and enterprise clients — workflows, creative analytics, and full control over campaigns across the whole team. For companies where performance marketing already runs at scale and needs more efficiency and automation.

A few numbers that speak for themselves:

• 4 years on the market — a stable, profitable company backed by international investors;

• 6× growth over the past year;

• 2,000,000+ businesses already use Zeely;

• #1 in its category in the US market;

• 200+ specialists on the team;

• Markets: US + worldwide.

Your Key Responsibilities:

• Lead the Backend Department and set the technical direction for a team of 15+ backend engineers;

• Own backend architecture and drive key technical decisions around scalability, reliability, performance, and system design;

• Lead the evolution of our AI Gateway — the core platform layer powering text, image, voice, avatar, and video generation across multiple AI models and providers;

• Design and evolve AI orchestration pipelines, optimizing routing, fallback strategies, generation quality, latency, and cost;

• Scale backend services and infrastructure to support growing product traffic and increasingly complex workloads;

• Drive engineering excellence across code quality, architecture, security, observability, testing, and operational reliability;
