Senior Full-Stack developer

Join C Wire and Shape the Future of AdTech!

We are a fast-growing AdTech startup with offices in Zurich, Belgrade, and Vienna. Our mission is to help advertisers and publishers reach their full potential on the trusted web, using AI-driven targeting without ever collecting or sharing personal data.

Our systems process vast amounts of data every time users load articles on major news sites across Europe, powered by GoLang microservices on an EKS cluster and seamless data flow through PostgreSQL and Clickhouse. Our creatives are crafted with Svelte, and our self-service tools in Vue and Nest.JS.

As we scale rapidly, we need motivated engineers to build intuitive self-service tools and optimize creatives reaching thousands every hour. Ready to shape the future of AdTech with us?

Your role:

As a Senior Full-Stack Engineer, your focus will be on developing and designing the self-service platform. You’ll also design, integrate and optimize creatives on publisher sites and collect the needed metrics for reporting and billing advertisers.

You’ll write tests to harden your solution and design fast and reliable deployment pipelines.

Furthermore, you’ll work closely with the rest of the team to deploy and monitor your solutions and optimize product requirements with technical feasibility.

Ideally, you have

• BSc or MSc in Computer Science or a related field
• Passion for collaboration and strong interpersonal skills
• Proficiency in Typescript and Javascript
• Proficiency in frontend tools and technologies (HTML5/CSS3, Javascript ES6, webpack)
• Proficiency in writing CI/CD pipelines and automated tests (GitHub Actions, CircleCI, test containers, cypress / webdriver.io, jest)
• Experience with PrebidJS or other Advertising Technologies
• Experience with Linux, Docker and container orchestration frameworks like Kubernetes.
• Knowledge in database structure, design, query languages (e.g. SQL), large data sets, distributed systems, and fundamentals of mathematics and statistical concepts is a plus.
• Knowledge in creating and scraping instrumentation data is a plus (Prometheus, Grafana).

Engineering at C Wire

At C Wire, engineering is all about collaboration and flexibility. We work closely through pair programming and mob sessions, blending remote and in-office time. Flexibility is key—whether it’s family, hobbies, or that unavoidable local appointment, we get it.

We care deeply about creating simple, elegant solutions while keeping testability, operational challenges, and product impact top of mind. With a DevOps culture, we emphasize end-to-end ownership, deploying several times a day using trunk-based development to keep things fast.

Our afternoons are (mostly) meeting-free to help minimize context-switching. We’re metrics-driven, monitoring our services and crafting custom KPIs for daily and hourly revenue insights 📈. And yes, we’re tech geeks—vim, Linux, and all. Above all, we value transparency and honesty.

Join us if you’re ready for an engineering culture that’s flexible, fast, and passionate about innovation!
