What youll do:

Distributed software architectures are powerful but have their challenges, especially regarding debugging across devices. The traditional debugging method does not scale and that's because a call may involve multiple devices, and it's very hard to combine data to get a single stack trace. Therefore, tracing individual flows across a distributed system is an essential component in an observability system. However, current implementations focus on web applications and microservices. We want to build a modern distributing tracing system for a wireless solution. The system can gather information from the controller, the access point, and other deployed devices such as authentication servers and analytics services. Among others, use cases of such system include troubleshooting errors, anomaly detection, latency problems discovery, exploring dependencies, and validating functionality.

Your activities will include:

  • Research state of the art on distributed tracing.
  • Design of a low overhead code instrumentation system.
  • Definition of the tracing data model. For example, sampling rates, entry points, system components, integration with other observability methods.
  • Implementation and enablement of some flows.
  • Integration with a tracing collector (e.g. telemetry collector, Zipkin, Cisco DNA-C, App Dynamics, custom).

Who you are:
  • Willing to learn and work in a team
  • Independent and self driven
  • Creative problem-solving mindset
  • Enjoy looking at practical real-life challenges and thinking creatively to solve them.


What you need to be eligible:

  • Master student in Computer Science, Computer Engineering, Electrical Engineering, or a related major
  • Strong knowledge of programming and scripting languages (C and a scripting language like Python)
  • Good understanding of computer networks and networking technologies
  • Fluent in English


Why Cisco

#WeAreCisco, where each person is unique, but we bring our talents to work as a team and make a difference. Heres how we do it. We embrace digital, and help our customers implement change in their digital businesses. Some may think were old (30 years strong!) and only about hardware, but were also a software company. And a security company. A blockchain company. An AI/Machine Learning company. We even invented an intuitive network that adapts, predicts, learns and protects. No other company can do what we do you cant put us in a box! But Digital Transformation is an empty buzz phrase without a culture that allows for innovation, creativity, and yes, even failure (if you learn from it.) Day to day, we focus on the give and take. We give our best, we give our egos a break and we give of ourselves (because giving back is built into our DNA.) We take accountability, we take bold steps, and we take difference to heart. Because without diversity of thought and a commitment to equality for all, there is no moving forward.

So, you have colorful hair? Dont care. Tattoos? Show off your ink. Like polka dots? Thats cool. Be you, with us!
