ABOUT THIS MANDATE
Recruiting Bond has been exclusively retained by one of India's most well-established digital platform organisations — a company operating at the intersection of Technology, Information, and Media — to identify and place a world-class Backend Tech Lead who can drive a transformational engineering agenda at scale.
This is not an ordinary role. The organisation is executing a high-stakes, large-scale modernisation of its backend infrastructure — migrating from legacy monolithic systems to resilient, cloud-native, AI-augmented distributed architectures that serve millions of concurrent users. The person in this seat will be a core pillar of that transformation.
We are looking exclusively for the top 1% — engineers who think in systems, own outcomes, and lead by example.
THE OPPORTUNITY AT A GLANCE
🏗️ Architecture Ownership
Drive system design decisions across the entire backend platform. Shape the future of distributed, fault-tolerant architecture.

- Implement circuit breakers, bulkheads, and resilience patterns using Resilience4j / Hystrix or equivalents
- Engineer Dead-Letter Queue (DLQ) strategies and event reprocessing pipelines with guaranteed delivery semantics
- Apply Saga orchestration and choreography patterns for distributed transaction integrity
- Execute zero-downtime deployments and canary release strategies with rollback capability
- Design and enforce multi-region disaster recovery and business continuity protocols
3. AI-Driven Engineering Practices
- Champion LLM and GenAI adoption as first-class tooling across the software development lifecycle
- Apply prompt engineering techniques for automated code generation, review, and documentation workflows
- Utilise AI-assisted debugging, root cause analysis, and predictive performance optimisation
- Build automation-first pipelines that reduce toil and accelerate delivery velocity
- Evaluate and integrate emerging AI developer tools into the engineering ecosystem
4. Engineering Leadership & Culture
- Own backend platforms end-to-end with full accountability across development, stability, and performance
- Actively mentor, coach, and elevate engineers at all levels (L3–L6) through structured 1:1s and code reviews
- Drive and lead technical hiring — from designing assessments to final hire decisions
- Partner with Product, Data, DevOps, and Security stakeholders to align engineering with business objectives
- Represent the engineering org in cross-functional roadmap planning and architecture decision reviews
