A venture-backed NauWork client that provides Simulation-as-a-Service for scaled network systems is seeking a Software/Systems Engineer [Network Modeling] with strong networking experience for complex/distributed systems and/or high-performance computing services.
The company operates a High-Performance Computing Platform (HPC) in the public cloud that leverages the latest open source technologies and middleware to run network simulations at scale. The team strives to remove each and every barrier that would keep the simulation software/network development team from executing faster and releasing a clean, quality product.
About The Job
The company is looking for a Software Engineer with a strong understanding of data center design configurations, distributed systems and/or high performance computing, and exposure to network simulation/emulation/virtualization. The primary responsibility of the role is to help design and develop software to run network simulations using the ns3 framework.
Responsibilities
Define and implement network simulations using customer-driven data center configurations. Analyze results and provide high quality insights.
Develop and maintain the company's simulation methodology for performance modeling of network and network devices, including queueing & packet processing models. Incorporate functional models into performance models.
Help identify simulation model bottlenecks and bugs, and devise solutions to these problems.
Operate as a self-driven team player at times independently and with minimal direction, and at times collaborating closely with co-workers and customer engineers
Own device and system models for large-scale distributed applications.
Specify the methodology and software required to exercise the models; log results, perform regression testing, or correlate against real life systems.
Leverage simulation efforts for customer validation by adjusting the model to customer variants, and drive evolution of the models to achieve both customer and internal development goals.
Requirements
Understanding of hardware and system software design for network interfaces.
Knowledge of hardware and software design and configurations for large data centers.
Strong experience in data communications, networking protocols, and standards such as TCP/IP, UDP, and data link layer protocols including Ethernet. Prefer experience with RDMA, RDMA over converged ethernet (RoCE), or Infiniband RDMA.
Experience modeling network components in data center configurations, preferred.
Experience evaluating results and generating performance insights.
Experience with discrete event network simulation tools, such as ns-2, ns-3, or omnet++, to evaluate the performance characteristics of network components, preferred.
Strong coding ability with C++. Additional preference for Python.
Understanding of silicon chip architecture and fundamentals.
Good understanding of complex distributed systems, including experience debugging and solving performance issues in these environments.
Proficient understanding of source code management using GIT tools.
Bachelor’s Degree or equivalent in Computer Science, Electrical Engineering or a related field.
