(Senior) Network Engineer – SONiC

Permanent employee, Full-time · Remote (EU)

About:

We are seeking a skilled and driven Network Engineer with deep expertise in SONiC (opensource NOS) to join our growing infrastructure team. This is a key position as we begin the implementation and integration of SONiC-based whitebox switching into our datacenter environments. You'll work closely with the Network Engineering Lead and initially with support from our senior architect Marek, helping to shape our next-generation network stack.

Why this role matters

This is a new position created to support our strategic move toward open networking. SONiC will play a critical role in our datacenter operations, and we need an engineer who can take the lead on implementation, hardware selection, troubleshooting, and integration into our existing stack. You'll also be responsible for ensuring production readiness by applying patches, working with the community for hotfixes, and supporting automation.

Responsibilities:

Design, implement, and maintain datacenter network topologies using SONiC on whitebox hardware.
Troubleshoot complex network issues and ensure high availability, scalability, and reliability across the network stack.
Automate configuration management and network operations using Ansible, Python, and Bash.
Manage the full SONiC firmware lifecycle: patching, upgrading, testing, and contributing to the open-source community.
Select, evaluate, and maintain SONiC-compatible hardware platforms.
Collaborate with infrastructure and engineering teams to integrate SONiC into our broader ecosystem.
Share SONiC expertise internally through documentation, training, and code reviews.
Adapt to evolving priorities and contribute to company-wide infrastructure initiatives.

Qualifications:

Must-haves

Proven experience with SONiC: setup, customization, and troubleshooting.
Deep understanding of:
- Routing & switching protocols: BGP, EVPN, ECMP, VRF
- Network virtualization: VXLAN, GENEVE
- Linux networking: network namespaces, bridges, veth pairs.
Experience with FRR (Free Range Routing) and Docker
Proficiency in scripting and coding: Python, Bash, C/C++
Experience with Ansible for network configuration and automation.

Nice-to haves

Exposure to OpenStack networking components (OVN, OVS).
Familiarity with RoCE (RDMA over Converged Ethernet) technologies.
Experience in distributed or remote-first engineering teams.
Contributions to open-source networking projects or forums.

What we offer:

The opportunity to lead cutting-edge networking initiatives in a fast-scaling company.
Ownership of the SONiC integration strategy across our datacenters.
Remote-friendly setup with occasional travel (if desired).
Competitive compensation and benefits in a technically forward-thinking team.
