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 organizations rely more on cloud services and the Internet, the network has become a "black box" outside of their control. ThousandEyes gives organizations visibility and insight into the now borderless network. It arms them with an accurate understanding of how the network impacts their applications, users, and customers. ThousandEyes is used by some of the world's largest and fastest growing brands, including 4 of the top 5 SaaS companies, 4 of the top 6 US banks and 3 of the Fortune 5. ThousandEyes is backed by Sequoia Capital, Google Ventures, Tenaya Capital and Sutter Hill Ventures, with headquarters in San Francisco, CA.

What You’ll Do

The Datastores team is focused on our platform’s mission critical datastores (think ElasticSearch, Kafka, MongoDB, and MySQL). The team is responsible for all aspects of our platform’s datastores, such as availability, performance, change management, capacity planning, monitoring and emergency response. As a Principal Site Reliability on the team, you will focus on providing strong technical vision as well as help the team handle the company’s core datastore services, maintaining a constantly growing infrastructure capable of handling a very high volume of incoming data per day. 

We’re looking for talented engineers with a software or operations background, experienced in designing, analyzing, and troubleshooting large-scale high available datastores systems. You must be willing to work closely with our application development teams to ensure the reliability and performance of our infrastructure.


  • Collaborate and work closely with the software engineers to ensure that the ThousandEyes platform datastores infrastructure and services are designed and optimized for availability, latency, and performance.
  • Provide strong technical vision for your team and ensure consistent delivery on objectives.
  • You have a total of 5+ years of experience building and supporting missing critical services with focus on automation, availability, and performance.
  • Design, implement and maintain elastic and resilient datastores that support our platform as we grow to multi-region scale.
  • Drive and build automation wherever possible, enabling our datastores to scale effortlessly. Think self-service.
  • You have worked on large-scale distributed systems including multi-tiered architecture.
  • Participate in and contribute to improve our 24x7 incident response and on-call rotation.

Required Skills

  • 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.

We Are Cisco

#WeAreCisco, where each person is unique, but we bring our talents to work as a team and make a difference. Here’s how we do it.

We embrace digital, and help our customers implement change in their digital businesses. Some may think we’re “old” (30 years strong!) and only about hardware, but we’re also a software company. And a security 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 can’t 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? Don’t care. Tattoos? Show off your ink. Like polka dots? That’s cool.
