Junior Engineer - Infrastructure and Devops

Tamme is an ad-tech platform that balances supply and demand for double sided marketplaces that have a geographical element. For example, Deliveroo, Uber Eats etc need to make sure that they have the right ratio of riders to diners within a certain radius. If the ratio in an area isn't right then tamme makes sure that the perfect ads are showing in the right places in order to bring balance back to the marketplace. If everything is working perfectly then tamme tries to work out where it can expand to next, taking into account like for like suburbs and available channel reach everywhere around the world.

We value inclusion very highly. You will find no discrimination on the basis of race, religion, gender, sexual orientation, age, or disability status. We just care that you're good at your job.

Our Infrastructure and Devops team is one of the more interesting teams because not only do you get to work across a whole stack of different services, but you also get to contribute to and manage open source software projects. Most of our infrastructure is built via Infrastructure as Code through Nephelo (an in house system) to Cloudformation and then through across multiple continents.

 

Why we're interesting:

 - We have had to build a Real Time Bidder component that has to be able to handle 1.4million requests per second. These requests need to be (end to end) < 100ms

 - Most of our core processing is done using serverless.com on AWS Lambda.

 - We have an analytics engine that ha to be able to consume and understand interactions between people, not just interactions a user has made on a webpage.

 - Because we have to have similar infrastructure in multiple regions in the world we have had to build some of our own internal tools already to handle this, including:

   - Nephelo, which is a layer on top of cloudformation to help build out the same infrastructure in multiple regions, through a CI pipeline

   - FreeRange, allows our software to be able to locate our infrastructure without having to tell it what the exact address is, that way when things change in the infrastructure, the system is able to adapt

   - Shadchanit, helps us make sure that the right applications are facing the outside world and that the system is always evolving to ensure that our users are receiving the fastest route possible.

   - Yenta, which is a one way communication system from the middle out, that allows all of our edge locations to have the most up to date data available.

   - All of our software sits on AWS infrastructure and we get to play with some of the cooler new toys that they're bringing out before the go on the market.

 

Our Values:

Family First

At our core our team are a family, we strongly and staunchly believe that to build the best products and make the largest difference we can we have to start by supporting our team first.

Test, Fail, Learn

We're constantly trying new things, some of it works, some of it doesn't. It's okay to not get it right, that means we learned something new, and that's invaluable.

No Bullshit

Be up front, it's okay not to know, give feedback, take feedback and just be human. Honesty and openness are incredibly important to us.

No Arseholes

Yep, we can all be a bit of a dick on occasion but if you're an arsehole, don't bother applying, you'll hate it here. We're a team, a unit, a family. At tamme we care about getting the job done, working as a team and we care about each other.

Be Better
