Job Description

Role Overview

We are looking for a Backend Technical Architect who combines deep Python expertise, strong computer science fundamentals, and hands-on engineering rigor to design and build scalable, high-performance systems.

This is a high-ownership, high-impact role where the individual is expected to:

• Operate using first-principles thinking
• Be deeply hands-on with code, not just design
• Solve ambiguous, complex technical problems
• Drive end-to-end architecture and execution
  
  

• Ability to take ambiguous problem statements and convert them into clear, executable technical plans
• Consistent delivery of high-quality, production-grade systems with strong reliability and performance
• Demonstrated impact in eliminating bottlenecks, improving system efficiency, and scaling platforms
• Strong influence across teams through clear technical communication and leadership
  
  

• Architecture & System Design
• Design scalable, fault-tolerant distributed systems using microservices architecture
• Ensure systems are built with observability, resiliency, and extensibility by design
• Hands-on Development (Python-first)
• Actively contribute to core codebases with high-quality, maintainable Python code
• Lead by example in coding standards, debugging, and performance optimization
• Build reusable frameworks, libraries, and internal platforms
• Problem Solving & Performance Engineering
• Identify and resolve system bottlenecks (CPU, memory, I/O, network, DB)
• Drive performance tuning, load testing, and scalability improvements
• Establish benchmarks and SLO-driven engineering practices
• Lead root cause analysis (RCA) and implement long-term fixes
• Design guardrails to prevent 99% of known failure modes
• Improve observability (metrics, logs, traces) across systems
• Technical Leadership & Mentorship
• Lead a team of senior, mid-level, and junior engineers
• Mentor engineers in system design, coding best practices
• Raise the overall engineering bar across teams
• Cross-Team Collaboration
• Work effectively with frontend, backend, data, and platform teams
• Ensure features are implemented end-to-end in a cohesive and scalable manner
• Communicate technical concepts clearly to both engineers and leadership Required
  
  

• Strong hands-on experience in Python (design, debugging, performance tuning)
• Experience building and scaling microservices-based distributed systems
• Deep understanding of concurrency, parallelism, async processing, and event driven architectures
• Strong grasp of API design (REST/gRPC)
• Experience with data systems: SQL (Postgres) and NoSQL (MongoDB, Elasticsearch), Messaging systems (Kafka, Event Hubs, queues), data-intensive systems and pipelines
• Hands-on experience with cloud and infrastructure: AWS / Azure / GCP, Docker, Kubernetes, CI/CD pipelines
• Familiarity with observability tools: Prometheus, Grafana, Kibana (or similar)
• Experience with workflow orchestration tools (Airflow, NiFi or equivalent)
• Exposure to Data / AI platforms (preferred)
• Strong focus on code quality, testing, and automation
• Comfortable using GenAI development tools (e.g., Cursor, Copilot) to improve productivity
• Experience in working with Ontology/Knowledge Graph in any complex data ecosystem is a huge plus
  
  

• Competitive salary and benefits package.
• Flexible hybrid working model.
• Opportunities for professional growth and development.
• Collaborative and inclusive work environment.
• Access to the latest technologies and tools.
• Opportunity to make a tangible impact on cutting-edge Retail/ CPG AI solutions.
