About GreedyGame / PubScale

GreedyGame (PubScale) is a Bengaluru-based, Google Certified Publishing Partner building an all-in-one platform for app growth and monetization, trusted by 1500+ publishers and advertisers worldwide. Our products span native and immersive ad formats, mediation, user acquisition (GROW), and offerwalls.

About the Role

We're looking for a Software Engineer Intern to work on GAM. You'll get hands-on experience building and shipping real backend and frontend features used by publishers processing large volumes of ad traffic daily, while working closely with engineers who operate at the intersection of adtech, data, and scale

What You'll Do

Build and maintain backend services that integrate with Google Ad Manager (GAM) and multiple third-party ad networks

Develop frontend features and dashboards in React used by both publishers and internal teams for tasks like ad unit management, monitoring, and operational workflows

Work with large datasets - ad traffic, impressions, and performance metrics - to support reporting and optimization.

Integrate with external APIs (ad networks, mediation platforms, data providers)

Collaborate with senior engineers and product managers to design, build, test, and ship features end to end

Debug and optimize existing systems for performance and reliability at scale

Must-Haves

Proficiency in Go for backend development

Working knowledge of React for frontend development

Experience with relational databases (MySQL or PostgreSQL) and MongoDB

Solid understanding of data structures, algorithms, and API design fundamentals

A builder's mindset - comfortable navigating ambiguity and shipping in a fast-moving environment

Good to Have

Experience with ClickHouse or BigQuery for large-scale data querying/analytics

Familiarity with AdMob or AdSense

Freelance project experience

Prior experience working at a startup

Experience building MCP (Model Context Protocol) servers

Why Join Us

Work on a product that handles massive scale - real ad traffic, real publishers, real revenue impact

Direct mentorship from experienced engineers, with ownership over meaningful pieces of the product

A fast-paced adtech startup environment where your code ships to production, not just a sandbox

Exposure to the intersection of ad tech, large-scale data systems, and external API integrations

Note for the candidate: We value curiosity over perfection. If you love building entire systems from the ground up and are ready to dive deep into the world of ad-tech tooling, we want to hear from you.
