Team Lead Full Stack Engineer

High-Load ML AdTech Platform | Real-Time Systems | Remote

🌍 Who we are:

Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies in a wide range of industries.

🧩 About the Product:

We build a proprietary ML-driven platform for programmatic user acquisition and retargeting in the mobile app space. It processes tens of terabytes of data daily and handles millions of real-time requests per second with low latency — directly driving client growth and revenue.

Operating at this scale requires strong distributed architecture, performance optimization, and security. Our clients are major app developers who depend on reliable, high-throughput systems and measurable ROI.

As a Full Stack Team Lead, you will own the design and evolution of our core real-time ad-serving infrastructure. You’ll lead a distributed team of 4 engineers, drive technical direction, and ensure performance, availability, and security at scale.

This is a hands-on role: ~50% coding and architecture, ~50% team leadership, sprint planning, and stakeholder collaboration.

You’ll work closely with the Executive, Product, Data, and Design teams to deliver scalable solutions and shape the product roadmap.
