Software Engineering, Data Science
London, UK
Posted on Wednesday, June 12, 2024

Who We Are

The name ThousandEyes was born from two big ideas: the power to see what’s not ordinarily possible, and the ability to collect intelligence from vantage points as diverse and global as the Internet. As organizations depend on cloud services, the Internet has become their defacto network connecting cloud applications to users. Our Internet and cloud intelligence platform is like a ‘Google maps of the Internet’, providing the only collectively powered view of digital experiences end-to-end. We enable our customers made up of the world’s largest and fastest-growing brands, to identify problems before they impact revenue, brand reputation, or employee productivity.

In August 2020, Cisco Systems completed the acquisition of ThousandEyes, which now forms the ThousandEyes Business Unit within Cisco’s Network Services Business Group, and is a foundational component of Cisco’s growing Observability business.

About The Role

WAN Insights is the cornerstone of Cisco’s Predictive Networks vision. We wanted to go beyond reacting to network glitches, we wanted to anticipate them, and we did for Cisco Catalyst SD-WAN. Now, as we look forward to expanding to other segments, we need talented engineers to join our mission.

Our product has been featured on the Cisco Live stage, Gartner reports, and received numerous awards such as 2023 Cloud Computing Product of the Year Award, 2023 CRN Tech Innovators Award, and Cloud Management Solution of the Year in the UK Cloud Excellence Awards.

In this position you’ll play a key role in turning data into valuable insights for our customers. Responsibilities range from writing big data pipelines to REST APIs, from designing database tables to optimizing query performance. We expect solid computer science fundamentals, ownership, willingness to learn and to do, and most importantly a great team spirit.

What We’re Looking For

  • An experienced Software Engineer with excellent knowledge of computer science fundamentals.
  • Expertise in Python or Golang, as they're the most prominent programming languages in our codebase; we are also open to considering applicants with experience in Java, Scala, C# or C++.
  • Practical experience with distributed processing of large amounts of data.
  • Hands-on experience with PySpark/Spark
  • Experience working according to DevOps best-practises (CI/CD, testing, familiarity with Github/Gitlab).
  • Good knowledge of at least one major relational database, e.g., MySQL, PostgreSQL.


  • Familiar with Docker, Kubernetes and cloud technologies such as AWS.
  • Airflow and Kafka.
  • Familiarity with NoSQL databases.
  • Familiarity with REST API development.

Cisco values the perspectives and skills that emerge from employees with diverse backgrounds. That's why Cisco is expanding the boundaries of discovering top talent by not only focusing on candidates with educational degrees and experience but also placing more emphasis on unlocking potential. We believe that everyone has something to offer and that diverse teams are better equipped to solve problems, innovate, and create a positive impact.

We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification. Research shows that people from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy. We urge you not to prematurely exclude yourself and to apply if you're interested in this work.

Message to applicants applying to work in the U.S. and/or Canada:

When available, the salary range posted for this position reflects the projected hiring range for new hire, full-time salaries in U.S. and/or Canada locations, not including equity or benefits. For non-sales roles the hiring ranges reflect base salary only; employees are also eligible to receive annual bonuses. Hiring ranges for sales positions include base and incentive compensation target. Individual pay is determined by the candidate's hiring location and additional factors, including but not limited to skillset, experience, and relevant education, certifications, or training. Applicants may not be eligible for the full salary range based on their U.S. or Canada hiring location. The recruiter can share more details about compensation for the role in your location during the hiring process.

U.S. employees have access to quality medical, dental and vision insurance, a 401(k) plan with a Cisco matching contribution, short and long-term disability coverage, basic life insurance and numerous wellbeing offerings. Employees receive up to twelve paid holidays per calendar year, which includes one floating holiday, plus a day off for their birthday. Employees accrue up to 20 days of Paid Time Off (PTO) each year and have access to paid time away to deal with critical or emergency issues without tapping into their PTO. We offer additional paid time to volunteer and give back to the community. Employees are also able to purchase company stock through our Employee Stock Purchase Program.

Employees on sales plans earn performance-based incentive pay on top of their base salary, which is split between quota and non-quota components. For quota-based incentive pay, Cisco typically pays as follows:

.75% of incentive target for each 1% of revenue attainment up to 50% of quota;

1.5% of incentive target for each 1% of attainment between 50% and 75%;

1% of incentive target for each 1% of attainment between 75% and 100%; and once performance exceeds 100% attainment, incentive rates are at or above 1% for each 1% of attainment with no cap on incentive compensation.

For non-quota-based sales performance elements such as strategic sales objectives, Cisco may pay up to 125% of target. Cisco sales plans do not have a minimum threshold of performance for sales incentive compensation to be paid.
