“I’ve never seen a job being done by a five-hundred-person engineering team that couldn’t be done better by fifty people.” - C. Gordon Bell

Your mission at Whereby*
Help us service 5 million monthly active users, with 250TB of daily traffic, by making our SFU architecture even more performant and make Whereby a globally reliable service. 
*This is the mission that moves you and your team through our strategic roadmap, and should be your focus for up to a year or two.

What is Whereby all about
Freedom to work from anywhere: our mission with Whereby is to give people freedom to live and work where they thrive.
📍 Our global HQ is in Oslo, Norway, but our users (and team) are worldwide - having been used in nearly every country in the world by millions of folk. 🌏
By making it possible to collaborate as well over video as you can in real life, we want to give you the choice to work from where your life happens. To allow you to be in a place where you can think and focus, but also allow a seamless and instant connection with others when you need to.
For our 60 team members, and also for our customers, we know that the ability to decouple location from work can be life-changing. They can afford the house they want, can spend less time commuting, be closer to nature, and their children get to grow up seeing their grandparents every day. Everyone on our team enjoys the enormous benefits that a flexible work policy brings, and we truly believe the future of work will gravitate towards our vision of the future.

Engineering at Whereby
We strongly believe in the superpowers of a well-lead, and expertly designed engineering team. We are an engineering-centric business who hopes to scale our operation sustainably, with beautiful code, an ethical approach to our users and data, and an innovative opinion on new technologies in the market.
We try to ensure both that we are building the right thing and building the thing right. We analyse data, talk to users, prototype and iterate. We focus on discovering and solving user problems, not just building and shipping features. As a member of our engineering team you’ll take on a key role in this process and see your work be used by millions of users worldwide.

🔍 What we're looking for in our Senior Software Engineer - SFU
We're looking for a Senior Software Engineer to join our Scaling team that runs our global infrastructure and media servers. You write easy-to-read and performant code with tests and documentation in case you get eaten by a yeti and are not afraid of challenging the status quo while aiming for radical simplicity in everything you do. 

🌎 We believe in everyone
We fundamentally believe talent is distributed to all of us in equal measure. We open our doors (physical or url) to everyone and we see our differences as a strength; it’s this philosophy that drives us towards our mission.
This means we see your unique history as having a value money cannot buy; we believe in the strength of every intersection of race, religion or belief, ethnic origin, different physical ability, family structure, socio-economics, age, nationality or citizenship, marital, domestic or civil partnership status, sexual orientation, gender identity.
