Full-Stack Engineer (Python + React) Work from Bangalore Office

Apply to this role only if you are willing to work from office. It is a great opportunity and we need very strong and passionate technical candidates only. Looking for immediate joiners ( within 0 to 15 days.Location is Bangalore.

Role Overview

We are seeking an experienced Lead Full-Stack Engineer to architect and build a digital

advertising budget management platform from the ground up. This platform automates budget

pacing, campaign scheduling, and quality assurance for paid media campaigns running across

major ad platforms — Google Ads, Microsoft Ads, Meta, LinkedIn, and TikTok — through a

unified third-party API.

This is a greenfield build. As the Lead Engineer you will own the technical architecture, make

stack and infrastructure decisions, and be responsible for the reliability of a system that

executes scheduled, business-critical operations outside of business hours. You will work

closely with a Product Manager (client-side) and a Junior Engineer, and will interface directly

with the outsourced DevOps vendor.

Responsibilities

Architecture & Technical Leadership

• Design and own the end-to-end technical architecture of the platform including the Budget

Engine, Scheduler, Unified API Connector, Campaign Intake Module, and Dashboard

• Make and document key technical decisions: database design, API abstraction strategy,

scheduling infrastructure, and deployment approach

• Establish coding standards, code review process, and engineering best practices for the

team

• Guide and mentor the Junior Engineer, reviewing their code and providing technical

direction

• Collaborate with the outsourced DevOps vendor on infrastructure setup, CI/CD pipelines,

and monitoring

Core Platform Development

• Build the Budget Engine: dynamic daily budget calculation logic supporting even pacing,

front-loaded pacing, mid-flight changes, campaign pauses, and extensions

• Build the Scheduler: reliable, time-based job execution for budget pushes, campaign

launches, and status changes — including off-hours and holiday periods

• Build and maintain the Unified API Connector: authenticated integration with Unified.to

covering Google Ads, Microsoft Ads, Meta, LinkedIn, and TikTok — handling push and pull

operations, rate limits, retries, and error handling

• Build the Audit Log: immutable, timestamped record of every budget decision, push event,

and manual override

• Build the Campaign Intake Module: structured data intake with validation against external

order management data

Reliability & Operations

• Design and implement retry logic, alerting, and failure recovery for all scheduled push

operations

• Ensure the scheduler operates reliably 24/7, including weekends and public holidays
• Implement role-based access control and secure credential management for all third-party

API keys

• Support post-launch platform operations — bug fixes, Unified.to API updates, performance

improvements

Requirements

• 4 to 6 years of full-stack software development experience
• Strong Python backend development skills — API design, background job processing,

database modeling

• Proficient in React for building operational dashboards and data-driven UIs
• Experience building and consuming REST APIs, including authentication, rate limiting,

pagination, and error handling

• Solid experience with background job / task scheduling libraries (e.g. Celery,

APScheduler, or equivalent)

• Experience with relational databases (PostgreSQL preferred) and data modeling for

audit/log use cases

• Demonstrated experience building production systems that must operate reliably outside

business hours

• Experience leading or mentoring junior developers
• Strong written communication — able to document architecture decisions and API

contracts clearly

• Comfortable working asynchronously with a remote, distributed team

Nice to Have

• Experience integrating with advertising platform APIs — Google Ads API, Meta Marketing

API, LinkedIn Campaign Manager API, or Microsoft Advertising API

• Familiarity with unified advertising API platforms (e.g. Unified.to, Skai, Marin Software, or

similar)

• Experience with budget pacing, bid management, or campaign automation tooling
• Familiarity with DevOps practices — CI/CD, containerization (Docker), cloud infrastructure

(AWS or GCP)

• Experience building data export pipelines or BI integrations (e.g. Tableau, Looker)
• Experience with AI-assisted QA or automated testing frameworks
