  • Ensure high availability and disaster recovery mechanisms.

  • Work timing needs to cater to US trading hours (3pm to 12am singapore time)

Key Requirements:

  • Technical Skills:
  • Expert-level C++17/20 programming, including multi-threading, lock-free data structures, and template metaprogramming.

  • Experience with low-latency optimizations (NUMA, kernel bypass, RDMA, DPDK, TCP/UDP tuning).

  • Strong understanding of market microstructure for US equities and crypto venues.

  • Familiarity with market data protocols (ITCH, OUCH, FIX, WebSocket APIs) and exchange-specific APIs.
  • Experience with real-time data processing and event-driven architectures.

  • Quant & Trading Knowledge:
  • Understanding of mid/high-frequency trading strategies, order types, and execution algorithms.

  • Familiarity with risk management and position tracking in real time.

  • Infrastructure & Tooling:
  • Proficiency in Linux systems programming and network programming.

  • Experience with build systems (CMake, Bazel), profilers, and debuggers (gperf, perf, valgrind).

  • Knowledge of cloud-native and on-prem deployments is a plus.

  • Education & Experience:
  • Bachelor's/Master's in Computer Science, Electrical Engineering, or related field.

  • 3–7 years of experience in low-latency trading systems or HPC environments.

Preferred Experience (Bonus Points):

  • GPU acceleration (CUDA) or FPGA programming for ultra-low latency strategies.

  • Experience with Python for data analysis or integration scripts.

  • Knowledge of cryptography and blockchain protocols for crypto execution systems.

  • Exposure to distributed systems and microservices architectures.

Soft Skills:

  • Strong problem-solving and debugging skills.

  • Ability to work in a fast-paced, iterative development environment.

  • Excellent communication for cross-functional collaboration.

  • High ownership mentality with a focus on reliability and performance.

What We Offer:

  • Opportunity to work on cutting-edge trading systems for global markets.
