Fullstack Team Lead (m/f/d)

India, Remote

Hello 👋 I am Servesh , Co- founder and CTO at Kayzen, and I am now looking for a Fullstack Team Lead to lead our Fullstack team. 🙌 But wait, you have not heard of Kayzen before? 😃

Kayzen is a mobile demand-side platform (DSP) dedicated to democratizing programmatic advertising. We enable leading apps, agencies, media buyers, and brands to run programmatic customer acquisition, retargeting, and brand performance campaigns through its self-serve and managed service options. Built on the three core pillars of performance, transparency, and control, Kayzen powers the world’s best mobile marketing teams with bespoke solutions that fuel business growth and deliver a competitive advantage. With an unprecedented scale of 160B+ daily ad requests from 1.6B+ unique users worldwide, we serve up to 1B+ ads per day in 180 countries. Kayzen is accessible through our APIs and user interface.

The Team

The Fullstack team owns the user-facing applications and interfaces that power the Kayzen platform — from our self-serve campaign management dashboard and real-time reporting suite to internal tooling used by our managed service teams. We work closely with product managers, designers, backend engineers, and data teams to deliver seamless, high-performance experiences. We are responsible for some of the most impactful work at Kayzen, including:

“The Console” which is the face of Kayzen we are very proud of.

Complex features which surface a lot of backend infrastructure via console

Almost 100% uptime with very well planned & executed project management

Sounds interesting. Isn’t it?

About the Role

We are looking for a coding-first Fullstack Team Lead who is as comfortable in the IDE as they are in a sprint planning session. You should be an early adopter of AI-assisted engineering (e.g., Claude Code, Cursor, Copilot) not just for your team's productivity, but in your own daily coding workflows. You will own the translation of complex product requirements into high-performance UIs while managing the 'execution gap' across your team's projects.

Responsibilities

Core responsibilities

Lead and mentor a team of Fullstack engineers, fostering a culture of quality, ownership, and continuous improvement

Hands-on contribution to the codebase — writing production code, conducting code reviews, and setting coding standards

Collaborate closely with Product, Design,QA and Backend teams to deliver cohesive, user-centric features

Define and drive the Fullstack technical strategy, architecture, and roadmap

Recruit, onboard, and grow fullstack engineering talent

Hands-on AI Implementation

Lead by example by integrating AI-powered coding agents and automated LLM-based testing into your own daily development cycle to set the pace for the team.

Architect and build 'AI-First' UI patterns, moving beyond static dashboards to generative, prompt-driven interfaces in collaboration with the LLM Platform team.

Project & Execution Management

Manage the 'Execution Gap' within the Fullstack pod, ensuring that high-level product roadmaps are broken down into actionable, high-velocity engineering sprints with zero 'slippage'
