Job summary

Pubscale engineering team in Bengaluru is seeking a senior engineer to own product surfaces end to end, from brief to production. You will shape React screens, Go APIs, and data models, while building a scalable design system for dashboards and reports.

The role emphasizes frontend excellence, strong TS and HTML/CSS fundamentals, and a hands-on backend mindset with Go, PostgreSQL, and MongoDB. You will mentor juniors and collaborate with cross-functional teams.

Qualifications

• 4–5 years building production web applications, with most time in React.
• Deep React and TypeScript experience (hooks, composition, performance, memoization).
• Strong HTML and CSS fundamentals (layout, responsive, accessibility).
• Proven track record shipping complex dashboards/tables with large data sets.
• Hands-on Go backend experience or willingness to go deep in Go (REST APIs).
• Experience with PostgreSQL and MongoDB (schema design, indexing, query optimization).
• Experience with Git workflows, CI/CD, code reviews, production debugging.
• Ownership mindset: scope work, flag risks, see features through to adoption.

Responsibilities

• Own product surfaces end to end: publisher dashboards, mediation, reporting, and workflows across React, Go, and data models.
• Define frontend structure: components, state management, loading/empty/error states, and fast, accessible pages.
• Build and grow design system: shared components for tables, filters, charts, and forms.
• Design APIs the UI needs: write/extend Go services, response contracts, pagination and caching decisions.
• Work with data layer: model/query PostgreSQL and MongoDB, support analytical stores, optimize slow queries.
• Ensure reliability: add monitoring, error tracking, tests, and root-cause production fixes.
• Mentor interns and engineers; write proposals and explain tradeoffs to product/engineering.

Job description

Pubscale is GreedyGame’s flagship product, a monetization, user acquisition, and growth platform used by 5,000+ apps and games and serving 100M+ daily ad impressions. Brands like Amazon, Dream11, MPL, ShareChat, and Mobikwik run on it, along with 1,000+ publishers across 20+ countries. We’re scaling from 1 to 10, and we need a senior engineer who can own product surfaces from brief to production.

The products you’ll own:

Pubscale:

monetization, user acquisition, revenue uplift, and business-growth analysis in one place

Immersive Ads:

native, non-intrusive ad formats with smart caching, priority loading, and adaptive refresh

Offerwall:

a reward-based engagement layer that monetizes non-paying users through personalized tasks, with eCPMs up to $1000 in Tier 1 geos and up to 3X more revenue in emerging markets

AdX & GROW:

Google Ad Manager monetization with premium demand partners, plus an AI-driven UA engine

What you’ll do:

• Own product surfaces end to end: publisher and internal dashboards for ad unit management, mediation, reporting, monitoring, and operational workflows, covering the React screens, Go APIs, and data model behind them
• Set the frontend bar: define how we structure components, manage state and server data, handle loading, empty, and error states, and keep data-heavy pages fast, accessible, and responsive
• Build and grow our design system: a shared component library for tables, filters, date-range pickers, charts, and forms
• Design the APIs the UI needs: write and extend Go services, shape response contracts, and make calls on pagination, aggregation, caching, and where computation should live
• Work with the data layer: model and query PostgreSQL and MongoDB, work with analytical stores for reporting, and catch slow queries and N+1 patterns before they reach users
• Make it reliable: add monitoring, error tracking, and tests where they matter, and drive production fixes to the root cause
• Raise the team’s level: review code, mentor interns and junior engineers, write technical proposals, and explain tradeoffs to product and engineering

What we’re looking for:

• 4–5 years building production web applications, with most of that time in React
• Deep React and TypeScript: hooks, composition, performance profiling, memoization, and knowing when to use React Query or Redux and when not to
• Strong HTML and CSS fundamentals: layout, responsive design, accessibility, and attention to visual detail
• A track record of shipping complex tables, filters, charts, and dashboards over large datasets, with virtualization, pagination, and efficient re-rendering
• Hands‑on backend experience in Go (or solid experience in another backend language and a willingness to go deep in Go): REST APIs, concurrency basics, and testing
• Comfort with PostgreSQL and MongoDB, including schema design, indexing, and query optimization
• Experience with Git workflows, CI/CD, code reviews, and production debugging
• Ownership: you scope work, flag risks early, and see features through to adoption

Bonus:

• Built or maintained a design system or component library
• Charting experience (Recharts, ECharts, D3, Highcharts) and data-visualization sense
• ClickHouse or BigQuery for analytics workloads
• Ad‑tech, analytics, or B2B SaaS dashboard experience
• Frontend performance work: bundle splitting, Core Web Vitals, rendering large datasets
• Experience building MCP servers or AI-assisted product features
• Startup experience or meaningful freelance or open‑source work

What makes you a great fit:

• You think in screens, flows, and the job a publisher is trying to get done, and you push back when a flow doesn’t serve that job
• You write clean, maintainable React and care about the details users actually notice
• You’re as comfortable opening a Go handler or a slow query as you are a component file
• You make pragmatic tradeoffs between speed and quality and explain them clearly
• You enjoy helping engineers grow and leave codebases better than you found them

Why Pubscale:

• Work on products used by millions of users every day
• Real ownership of the screens and services that publishers and internal teams rely on
• A direct line to the CTO and a seat at the table on technical direction
• A learning stipend for books, courses, and conferences, plus internal blogs
• Comprehensive benefits: health insurance, PTO, parental leave, and more
• A high-growth, inclusive, engineering‑led culture that supports experimentation and impact
