The position demands deep technical ownership across the entire stack, with particular emphasis on backend architecture, database performance, and cloud-native infrastructure.
Core Responsibilities
Architect and implement end-to-end systems handling high throughput and low latency requirements
Design scalable microservices and monolithic applications based on product needs and traffic patterns
Lead system design and scaling strategy for features handling millions of contacts, activities, workflows, and automation rules
Define service decomposition, API contracts, event schemas, and data migration strategies
Database schema design, indexing strategies, query optimization, and sharding/replication topologies
Build and maintain RESTful and GraphQL APIs with strict backward compatibility and versioning

Hands-on experience with major cloud providers (AWS and/or GCP mandatory): Multi-region deployments, serverless (Lambda/Cloud Functions), managed databases, and cost optimization
Expert in design patterns (creational, structural, behavioral) and architectural patterns. Proven ability to choose the right pattern, enforce it, and mentor the team on correct usage vs anti-patterns.
