🚨 We’re Building a “Top 1% Engineering Org”
We’re building a high-talent-density, AI-first R&D organization from scratch — inside a publicly listed company undergoing a full-scale transformation.
Think:
→ Rewriting legacy systems into AI-native architectures
→ Embedding LLMs + Agentic AI into core workflows
→ Reimagining platforms, infra, and data systems for the next decade
This is the kind of shift you’d expect from Google, Microsoft, or Meta —
Except you get to build it from day 0 → scale it globally.
About the Role / Team
We are building a next-generation AI-first R&D organization in Bengaluru, focused on solving complex problems across LLMs, Agentic AI systems, distributed computing, and enterprise-scale architectures.
This initiative is part of a publicly listed global company investing heavily in AI-driven transformation, re-architecting its platforms into intelligent, autonomous systems powered by large language models, workflows, and decision engines.
You will be working on:
- Agentic AI systems & LLM-powered workflows
- Distributed, scalable backend systems
- Enterprise-grade AI platforms
- Automation-first engineering environments
🚀 The Mandate
Own and evolve the technical backbone of an AI-first enterprise platform.

- Lead 0→1 and 1→N platform builds (LLM integrations, agentic systems, orchestration layers)
- Redesign legacy systems into scalable, modular, AI-native architectures
- Drive system design excellence across teams (APIs, infra, observability, reliability)
- Make high-stakes decisions on trade-offs (latency, cost, scalability, model performance)
- Mentor senior engineers and influence engineering culture/org standards
- Partner with product, data, and leadership on long-term technical strategy
🧠 What We’re Looking For
- Proven track record building high-scale backend or platform systems
- Deep expertise in distributed systems, microservices, cloud (AWS/GCP/Azure)
- Strong exposure to data systems/infra / Data / real-time architectures
- Experience or strong interest in LLMs, GenAI, or AI system design
- Exceptional system design, abstraction, and problem-solving ability
- High ownership mindset — you think in terms of systems, not tickets
- Strong coding skills in Python / Java / Go / Node.js
- Solid understanding of data structures, system design basics, and backend architecture
- Experience building scalable APIs and services
- Familiarity or curiosity around AI/LLMs, async systems, or event-driven design
- Strong debugging, problem-solving, and ownership mindset
- Solve hard system problems (latency, scale, reliability)
- Drive cross-team technical decisions and standards
- Mentor senior engineers and influence org-wide architecture
- Design large-scale distributed systems and backend platforms
- Mentorship & Technical Leadership
- Expertise in system design, scalability, and performance optimization
Nice to Have
- Experience integrating LLMs, vector databases, or AI pipelines
- Contributions to architecture at scale
- Experience with Agentic AI / LLM orchestration frameworks
- Background in product engineering or platform companies
- Exposure to global-scale systems (millions of users / high throughput)
🔥 What Sets You Apart
- Built platforms used by millions of users / high-throughput systems
