Typescript Developer – C Wire team

We at Holycode are currently looking for a Typescript Developer with strong skills and proven experience who is ready to dive into the C Wire team, for a full-time engagement, to join our team of passionate IT professionals, here in our Belgrade office.

C Wire is a fast-growing AdTech startup located in Zurich, Belgrade, and Wien. They are on a mission to strengthen free and independent journalism and protect your online privacy. C Wire does this by providing a platform where advertisers can create and deliver powerful advertising campaigns. With their advertising formats, publishers can generate fair and sustainable revenue from their readers, and they do it in a non-creepy way: “We do contextual advertising, using our own proprietary technology. We do not collect and share your data.”

How do they do it?

C Wire deals with a lot of data, and a lot of traffic. Really, a lot!

They get requests every time you load an article on your favourite news website. That multiplied by the biggest news sites in Switzerland, Germany, Austria, and the UK. They scrape, store and categorize all of the articles for contextual targeting.

The heavy lifting is taken care of by their GoLang-based microservices running on an EKS cluster. Data is stored in Postgres and Clickhouse DBs and they’re able to time travel using a Flux capacitor distributed log and Pulsar.

C Wire’s creatives are built using Svelte and the self-services are developed in Vue and Nest.JS.

Why do they need you?

C Wire needs to scale, provide easy-to-use self-service tools for campaign management, and optimize creatives that get thousands of views every hour. They need smart and motivated engineers to do so. Would you like to join them in this mission?
