RTB House is a next-generation performance demand-side platform (DSP) that uses proprietary Deep Learning AI algorithms to help brands grow. The company is the market leader in driving performance using Deep Learning across the entire purchase funnel. 

Founded in 2012 and now operating in 90+ markets, RTB House has always been private-by-design. It embraces first-party advertising and a relentless approach to innovation. RTB House offers end-to-end Deep Learning-powered AdTech products and solutions to maximize conversion, drive new customer acquisition, create engagement, and fuel long-term demand for a global base of clients.

Our infrastructure processes over 26 million HTTP requests per second and runs across four global data centers (EU, APAC, US East, and US West), powered largely by open-source technologies and modern infrastructure automation.

Our Network Infrastructure Team is responsible for designing, building, and maintaining the global network that powers RTB House's platform. We manage hundreds of switches and routers across our data centers, develop our own network automation tools, and ensure the reliability, low latency, and scalability of our entire network stack. 

You Will:

• Execute Linux low-level networking tuning and debugging to squeeze maximum performance out of our OS stack.


• Design, expand, and manage our global network infrastructure (LAN/WAN) across multiple data centers.


• Work with cutting-edge, open-source technologies like SONiC (Software for Open Networking in the Cloud), helping to shape the future of our network.


• Bring a DevOps mindset to networking by automating provisioning, configuration, and monitoring with Ansible, Python, and version-controlled workflows.


• Shape the production SONiC ecosystem by developing daemons and automating builds and testing.


• Ensure the security, reliability, and scalability of the network through proactive monitoring and maintenance.


• Troubleshoot and resolve complex network issues.


• Collaborate with other infrastructure and development teams to deliver fast and reliable services.


• Participate in key strategic projects, such as data center expansions and designing new network components.

Desired Experience: 

• Excellent command of a Linux/UNIX environment at the System Administrator level or higher, sufficient to work comfortably on the command line, debug, and optimize the system.


• Experience with Linux low-level networking tuning and debugging.


• Understanding of network fundamentals, including switching, routing (IPv4/IPv6), and TCP/IP.


• Proven experience with dynamic routing protocols, especially BGP.


• Experience with network automation (e.g., using Ansible, Python).


• Familiarity with modern data center technologies like Kubernetes networking, EVPN, VPP, and eBPF.


• Ability to quickly learn new technologies and adapt to a constantly evolving environment.


• Fluency in English (written and spoken).


• Nice to have: Experience with cloud networking (GCP, AWS) for hybrid environments.

Selected Technologies: 

• Network OS: SONiC, Junos, RouterOS


• Routing & Protocols: BGP, EVPN


• Automation: Ansible, Python, Git, Puppet


• Software Routers: FRR, BIRD, Kube Router


• Monitoring: Prometheus, Grafana, SNMP, Zabbix


• General: Linux (Debian/Ubuntu), Proxmox

We Offer: 

• Impact on large-scale infrastructure processing millions of requests per second


• Collaboration with experienced Administrators and Engineers


• Opportunity to operate with modern open-source infrastructure technologies


• Real impact on the development of a global AdTech platform


• Flexibility when it comes to the collaboration model and time
