BACKEND SOFTWARE ENGINEER (LOW LATENCY) at Zwift
Rio de Janeiro, BR

WHO WE ARE:

 

 

Zwift is a digital destination for fitness enthusiasts that is redefining indoor exercise. We took the boring indoor routine and game-ified it, by developing an at-home training experience that connects cyclists and runners with each other around the world. We’re on a mission to make more people, more active, more often.

 

Launched from the sunny beaches of Long Beach, CA with offices in NYC, London, and Rio de Janeiro, the Zwift community is active in 195 countries (yup - more countries than the United Nations) and growing. We’re endlessly positive, relentlessly inventive, and always looking to improve… wanna join?

 

 

WHO WE'RE SEEKING:

 

 

The Zwift server platform runs on an heterogeneous and distributed cluster composed of several different layers and nodes which require a number of different technologies to integrate on a 24/7 platform for the international user community. We are constantly modifying the software, adding and improving features and accommodating the increased load that comes with the steady growth of our successful business.

 

One of the major server components is its REST API that provides authentication and persistence services to the Zwift Game, Web, and Mobile Applications. All new features modeled by the API Team conform to an established load and performance standard, allowing the MMO application to provide optimal user experience to our growing community of international users. If you love technology, you will feel at home in the API Team. Another major backend component is a cluster of so-called relay servers, our low-latency nodes which receive the live data from our users (power, cadence, etc.) and forward that information to every other user (roughly speaking). Relays process a huge amount of data per second, so there are naturally a number of performance bottlenecks we should keep an eye on, and work towards constant improvements. If you love algorithms, the Relay Team is where you want to be.

 

We are expanding our staff in Rio to address the demand for new functionalities and work with our offices in Los Angeles, New York and London. Some international travel may be required.

 

 

WHAT YOU'LL DO:

 

 

The Backend Software Engineer will be part of a high performance team helping with the design and implementation of our high availability, low latency, near real time game server infrastructure using custom network protocols and high performance message processing techniques. The quality is ensured by using Test Driven Development, Code Review, Static Analysis and Load & Performance stress tools.
