Who We Are

The name ThousandEyes was born from two big ideas: the power to see things not ordinarily possible and the ability to collect insights from a multitude of vantage points. As the world continues its digital transformation and relies more on cloud services and the Internet, the “network,” which is now both public and private, has become a black box our customers cannot see or understand.  

Our Internet and cloud intelligence platform delivers the only collectively powered real-time view of the Internet and private networks, cloud, and SaaS platforms, helping enterprises and service providers identify problems before they impact revenue, damage brand reputation, or halt employee productivity. 

In August 2020, Cisco Systems completed the acquisition of ThousandEyes, which now forms the ThousandEyes Business Unit within the Cisco Networking Business Group and is the Network Assurance solution for Cisco across the Cisco Networking Cloud and Cisco Security Cloud. ThousandEyes is also a foundational component of Cisco’s growing Full-Stack Observability (“FSO”) business. 

About the role

The Datastores team is focused on running our platform’s mission critical datastores (think ElasticSearch, Kafka, MongoDB, MySQL, etc). The team is responsible for all aspects of our platform’s datastores reliability, such as availability, performance, change management, capacity planning, monitoring and emergency response. 

As a Principal Site Reliability you will focus on innovating and providing strong technical vision as well as work with the team to build reliable, scalable and highly available datastores on a constantly growing multi-region scale platform. You will partner with leaders across ThousandEyes as a datastores subject matter expert to help design the best architectures and processes, and be a role model for the Engineering team in delivery and team work.

What You’ll Do

We’re looking for a reliability-focused engineering leader to focus on automation and help drive datastores operational excellence to a new level. With evergrowing volumes of data and operating at a multi-region scale this is an opportunity for you to join a team and help take the ThousandEyes platform’s datastores to a new level.

Here are some of the main things we are looking for:

  • Deep knowledge of datastores. You have experience building and supporting mission critical datastores, and be happy talking relational and nosql. You are able to ensure that the ThousandEyes platform’s services are using the right datastores infrastructure, designed and optimized for availability, latency and performance.

  • Strong technical vision. You can collaborate with and beyond the team to formulate a compelling vision for the systems the team owns. You have the communication skills to sell it and to make sure it is represented in the team’s strategy and roadmap.

  • Expert in reliability. This is a hands-on role, so you will be excited by the opportunity to write software, automate and build reliable systems in order to enable our datastores to scale effortlessly. Think self service. You will have many examples of successfully delivering complex systems. 

  • Natural collaborator. It takes a village to do anything worthwhile, and you’re happy working across Engineering and Product Management to help shape the future direction of the platform’s datastores.

  • Effective mentor. You have a passion to up-level the team and those around you. You are open to learning as well…nobody is an expert at everything.


  • Ability to design and implement scalable and well tested solutions, with focus on datastores.

  • Ability to write high quality code in Python, Go, or equivalent languages.

  • Strong Infrastructure as Code skills, ideally with Terraform and Kubernetes.

  • Good knowledge of cloud provider managed services (ideally AWS), and how they can be leveraged in our context.

  • Good understanding of Unix/Linux systems, the kernel, system libraries, file systems, and client-server protocols.

  • Strong communication and documentation skills.

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.

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.
