Ctruh is looking for a deeply technical, hands-on Senior Backend Engineer - someone who can architect systems in the morning, write production-grade code in the afternoon, and scale infrastructure to power millions of 3D and XR experiences.

You will own the entire backend ecosystem: architecture, APIs, databases, infrastructure, performance, and reliability. This is not an oversight or management-only position - it is a builder’s role where you design, code, deploy, and optimize mission-critical systems.

You will make foundational decisions, build distributed systems that handle massive 3D processing workloads, and lead backend engineering direction as the platform scales globally.

What You’ll Build

1. System Architecture & Design

• Evaluate microservices vs monoliths based on product stage
• Design REST, GraphQL, and real-time WebSocket APIs
• Build event-driven systems for asynchronous processing
• Architect multi-tenant systems with strict data isolation
• Maintain architectural documentation and technical specifications

2. Core Backend Services

• Build high-performance APIs for 3D content, XR experiences, analytics, and user interactions
• Create 3D asset processing pipelines for uploads, conversions, and optimization
• Develop distributed job workers for CPU/GPU-intensive tasks
• Build authentication and authorization systems (RBAC)
• Implement billing, subscription, and usage metering
• Build secure webhook systems and third-party integration APIs
• Create real-time collaboration features via WebSockets or SSE

3. Data Architecture & Databases

• Design scalable schemas for 3D metadata, XR sessions, and analytics
• Model complex product catalogs with variants and hierarchies
• Implement Redis-based caching strategies
• Build search and indexing systems (Elasticsearch, Algolia)
• Architect ETL pipelines and data warehouses
• Implement sharding, partitioning, and replication strategies
• Design backup, restore, and disaster recovery workflows

4. Scalability & Performance

• Build systems designed for 10x–100x traffic growth
• Implement load balancing, autoscaling, and distributed processing
• Optimize API response times and database performance
• Implement global CDN delivery for heavy 3D assets
• Build rate limiting, throttling, and backpressure mechanisms
• Optimize storage and retrieval of large 3D files
• Profile and improve CPU, memory, and network performance

5. Infrastructure & DevOps

• Architect AWS infrastructure (EC2, S3, Lambda, RDS, ElastiCache)
• Build CI/CD pipelines for automated deployments and rollbacks
• Use Infrastructure-as-Code tools (Terraform, CloudFormation)
• Set up monitoring, logging, and alerting systems
• Use Docker and Kubernetes for container orchestration
• Implement security best practices for data, networks, and secrets
• Define disaster recovery and business continuity plans

6. Integration & APIs

• Build integrations with Shopify, WooCommerce, Magento
• Design webhook systems for real-time events
• Build SDKs, client libraries, and developer tools
• Integrate payment gateways (Stripe, Razorpay)
• Implement SSO and OAuth for enterprise customers
• Define API versioning and lifecycle/deprecation strategies

7. Data Processing & Analytics

• Build analytics pipelines for engagement, conversions, and XR performance
• Process high-volume event streams at scale
• Build data warehouses for BI and reporting
• Develop real-time dashboards and insights systems
• Implement analytics export pipelines and integrations
• Enable A/B testing and experimentation frameworks
• Build personalization and recommendation systems

The Ideal Candidate

• You are a backend engineer first and architect second - someone who still enjoys writing code, debugging complex issues, and solving scaling problems hands-on.
• You have built systems from the ground up and experienced the challenges that come with scaling them. You think in systems, evaluate trade-offs clearly, and design architectures that are practical, resilient, and future-proof.
• You are comfortable discussing microservices vs monoliths, choosing the right database for a use case, designing APIs, and introducing caching or queues when appropriate. You have made architectural decisions, optimized them later, and learned from the process.
• You stay close to the code. You pair program, review pull requests, jump into production incidents, and ship features alongside your team. You enjoy designing high-level architecture and then implementing the most critical components yourself.
• You balance ambition with pragmatism. You know when to use managed services, when to build custom solutions, and how to ship iteratively while maintaining system stability.
• Most importantly, you are a builder - someone excited to architect the backend foundations of a fast-growing XR platform, optimize performance for massive 3D workloads, and design infrastructure that supports global, real-time immersive experiences.
