Trading Infrastructure is a global organization of Engineers who architect, build and maintain our world-class infrastructure. From colo design/implementation, to optimizing our exchange connectivity, to building world class low latent Wide Area Networks, we leverage research and automation to consistently adapt and innovate our infrastructure to scale and drive our trading and evolving business.

Jump is looking for a Digital Modem Engineer to join our world class wireless team. In this role, you will you will lead the design and development of custom, low-latency modem architectures for our point-to-point wireless networks around the globe.

What You'll Do:

• Design, simulate, and realize innovative physical layer wireless communication algorithms for low latency applications
• Implement modem/system models and perform detailed performance investigations to allow performance sign-off and enable RTL development
• Collaborate with digital designers and firmware developers to realize algorithms with power and area efficient implementation

Skills You’ll Need:

• At least 5+ years of experience in the design, build, and deployment of digital modem systems
• Deep knowledge and demonstrated experience in digital modem design, including
• Transmit and receive pulse shaping digital filter design
• Symbol rate throughput, latency, and spectral occupancy analysis and optimization
• Carrier/symbol clock offset tracking and recovery
• Adaptive equalization using blind, training-based, and decision-directed algorithms
• Channel modeling and simulation
• Fixed point design, simulation and analysis
• Experience with Python, C/C++ and/or Matlab for algorithm development, modeling (floating-point and fixed-point) and link-level simulation
• MS/PhD in Electrical/Computer Engineering, Computer Science, or equivalent experience
• Reliable and predictable availability 

Bonus Points:

• Experience in logic design for wireless modem FPGAs, ASICs or custom data-path components for DSP applications (sequential and arithmetic components)
• Familiarity with Radio Frequency (RF) and microwave components: oscillators, mixers, attenuators, amplifiers, couplers, isolators, Printed Circuit Boards (PCB) layout
