About Zanskar Research

Zanskar Research is a quantitative proprietary trading firm headquartered in Bangalore, operating at the cutting edge of high-frequency and algorithmic trading across Indian and global markets. Our edge is technology - and we intend to keep it that way. Every microsecond counts, and the engineers who build here understand that deeply.

The Role

We're looking for a highly experienced Go engineer to join our core infrastructure team. You'll be embedded in the engine room - building, optimizing, and scaling the systems that power our trading strategies. This is a fully onsite role in Bangalore, 5 days a week, working alongside a tight-knit team of quants and engineers.

Responsibilities

• Design and build low-latency, high-throughput trading infrastructure in GO.
• Develop and maintain order management systems (OMS), execution engines, and market data pipelines
• Optimize critical paths for sub-millisecond performance — profiling, benchmarking, and tuning
• Integrate with exchange APIs (NSE, BSE, CME, or similar) and co-location environments
• Build reliable, observable internal services using gRPC, Protobuf, and messaging systems
• Work closely with quant researchers to implement and deploy strategy-level components
• Own reliability — participate in incident response and own SLOs for your systems
• Review code, set architectural standards, and uplift the engineering team technically

Requirements

• 4+ years of professional Go development with production deployments at scale
• Expert-level understanding of Go concurrency: goroutines, channels, sync primitives, context management
• Deep knowledge of Go's memory model, GC behavior, and performance profiling (pprof, trace)
• Demonstrable experience building low-latency or real-time systems (HFT, trading, gaming, telecom, etc.)
• Strong understanding of TCP/IP networking, kernel bypass, and socket optimization
• Hands-on with Linux performance tuning: CPU affinity, NUMA, IRQ affinity, huge pages
• Experience with market data feeds, FIX protocol, or financial exchange connectivity — a strong plus
• Proficiency with gRPC / Protobuf and high-performance message brokers (Kafka, NATS, or similar)
• Solid fundamentals in distributed systems: consistency, fault tolerance, clock synchronization
• Comfortable reading and reasoning about x86 assembly for hot-path optimization
