You will design resilient, high-performance backend systems that handle millions of advertising operations daily, integrate with multiple advertising platforms, and serve as the foundation for our AI agent ecosystem.
This is a hands-on engineering role where youβll ship production code daily, collaborate closely with AI/ML teams, and directly impact thousands of brandsβ advertising performance.
What Youβll Own
1. Core API Development
- Build and maintain RESTful APIs serving web, mobile, and AI agent clients
- Design database schemas and optimize query performance for high-traffic endpoints
- Implement authentication, authorization, and rate limiting for secure API access
- Write comprehensive tests (unit, integration, E2E) ensuring code quality and reliability
2. Service Integration & Data Pipelines
- Integrate with advertising platform APIs (Meta Marketing API, Google Ads API, TikTok Ads)
- Build data ingestion pipelines processing campaign metrics, creative performance, and audience insights
- Handle webhook processing, event streaming, and asynchronous job processing
- Implement retry logic, circuit breakers, and graceful degradation for external service failures
3. AI-Ready Infrastructure
- Build backend services that support AI agent workflows and LLM integrations
- Design APIs that enable AI agents to query data, execute actions, and receive feedback
- Implement observability hooks (tracing, logging, metrics) for AI system monitoring
- Collaborate with Data Science teams to productionize ML models and predictions
4. Performance & Scalability
- Optimize API response times (P95 <500ms) and database query performance
- Implement caching strategies (Redis, CDN) for high-traffic endpoints
- Design for horizontal scalability using containerization and orchestration
- Monitor system health, troubleshoot production issues, and participate in on-call rotation
5. Code Quality & Collaboration
- Write clean, well-documented, and maintainable Python code following team standards
- Conduct thorough code reviews providing constructive feedback to peers
- Participate in pair programming sessions and knowledge-sharing activities
- Contribute to technical documentation, runbooks, and architectural decision records
What Youβll Bring
Required
- Bachelorβs degree in Computer Science, Software Engineering, or equivalent experience
- 5+ years of production backend development with demonstrable impact on system reliability and performance
- Python expertise: Strong proficiency in Python web frameworks (FastAPI, Flask, Django) and async programming
- API design: Experience building RESTful APIs with proper versioning, error handling, and documentation (OpenAPI/Swagger)
- Database proficiency: SQL expertise (PostgreSQL, MySQL) including schema design, indexing, and query optimization
- Cloud infrastructure: Hands-on experience with Google Cloud Platform (preferred) or AWS/Azure
- GenAI & Agentic Framework familiarity: Practical experience using GenAI tools (GitHub Copilot, ChatGPT, Claude) for development, understanding of LLM capabilities/limitations, worked on setting up agentic toolings such as RAG, Guardrails, Feedback loops, planning, MCPβs and orchestration tools etc...
- Containerization: Production experience with Docker and Kubernetes for service deployment
