The Application Window is expected to close on 6/30/25. However, the job posting may be removed earlier if the position is filled or if a sufficient number of applications are received.

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.

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 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.
