Sr Software Engineer low latency - Hybrid at Chicago, IL
Description :
This role engineers secure, scalable and reliable technology solutions, with minimal mentoring, to advance the client in the global marketplace and serve risk management needs of customers around the world.
Principal Accountabilities
- Focuses on Architecture and Solution efficiencies. Balances performance, capacity and reliability with core system functionality.
- Identifies potential opportunities for code optimization. Provides input for code reviews and helps with environment build deployments, release notes and build notices; Reviews code to proactively identify and mitigate potential issues and defects and helps to identify sources of defects as well as troubleshoots various forms of code.
- Writes optimized application modules and unit tests with minimal guidance. Understands low-level designs and how to incorporate into the larger application.
- Uses design tools to frequently share and communicate design ideas on larger systems. Comfortable using low level tools to examine the system (i.e. packet capture, hardware counters, etc).
- Utilizes knowledge of modern multi-processor architecture to tune the applications and systems for high throughput and low latency.
- Uses patterns frequently, contributing to best practice and process enhancements
