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
- System Architecture & Design
- Architect highly scalable backend systems from the ground up
- Define technology choices: frameworks, databases, queues, caching layers
- 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
- 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
- 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
- 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
- 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
- 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
- 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.
