- Architect scalable, fault-tolerant distributed systems with zero-downtime principles.

- Drive active-active, multi-region architecture strategy and DR readiness.

- Lead performance benchmarking, tuning, and capacity planning.

- Establish architectural governance and engineering best practices.

- Collaborate with business, product, and compliance teams.

- Mentor senior engineers and lead architecture reviews.

Mandatory Experience :

- 15+ years in backend/distributed systems engineering.

- Proven experience building ultra-low latency, high-scale systems.

- Mandatory 3-5 years of experience in stock broking / trading platforms / capital markets.

- Experience handling mission-critical systems with strict SLAs.

- Exposure to high-volume, real-time transaction systems.

Domain Expertise (Must Have - Broking Platforms) :
