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 all of the top 5 global software companies, 5 of the top 6 US banks, and 45 of the Fortune 500.

ThousandEyes pioneered Cloud and Internet Intelligence and is widely known as the ‘Google Maps of the Internet.’ Today, ThousandEyes is central to the global operations of the world’s largest and fastest-growing brands. The company was acquired by Cisco in August 2020, chartered with continuing to drive leadership in empowering organizations to see, understand, and improve digital experiences everywhere.

About The Team

At ThousandEyes, our mobile team is responsible for our mobile apps and our mobile SDKs. We develop and maintain a variety of mobile apps; some for our users directly, and some on behalf of our customers, including telecoms regulators around the world. Collectively, our mobile apps have hundreds of thousands of active users and have gained very positive reviews, in part due to our high engineering standards. We are currently working on some major enhancements to our mobile apps that will be popular amongst both our consumer and business customer base.

Additionally, the mobile team is responsible for our mobile SDKs. These SDKs provide all of our measurement functionality - e.g. for speed testing, latency testing, and much more - in a single well-documented, reusable library. Our iOS SDK not only powers our own iOS apps that are developed in-house but is also vended to our customers to integrate the power of the ThousandEyes tests into their own apps. To date, our SDK is deployed on more than one million handsets worldwide already.

What You Will Do

• You will be working directly in conjunction with the developers who write the measurement code (typically in C and C++) and exposing that measurement functionality via Swift APIs for use in the iOS SDK. 

• You will also ensure that we are collecting relevant environmental information alongside the measurement results in order for us to make sense of the results (e.g. approximate coordinates of the test, generation of cellular technology used), without compromising user privacy. Most crucially, you will place an emphasis on ensuring that we are exposing our functionality using clear, logical APIs, with excellent documentation and usage examples.

• You should have a solid track record of working with Swift in a professional context. Ideally, you will have already been responsible for maintaining SDKs or APIs that are used by third parties. 

• Some experience of writing C is highly desirable but not essential. A good understanding of networking concepts is also beneficial.
