Description

This role covers end-to-end qualification, bring-up, and shipping of production-grade SONiC platform releases across diverse white-box hardware platforms and ASIC architectures. The scope runs from low-level Linux kernel and platform driver bring-up to SWSS feature development, Redis state database tuning, and SAI/SDK bug isolation. The Technical Lead guides a team of systems developers, network engineers, and test automation specialists across multi-vendor testbeds, with delivery following Agile engineering methodologies. The position is available fully remotely, in the Warsaw office, or in a hybrid format.

Responsibilities

Leading end-to-end qualification, bring-up, and shipping of robust SONiC releases across physical switch targets in complex data center topologies
Designing, extending, and debugging core SONiC subsystems including SWSS, syncd, Redis state databases, and Linux system services
Systematically isolating failures across all layers and driving resolution with silicon vendors
Debugging transaction processing and pub/sub notification mechanisms between APPL_DB, ASIC_DB, and syncd to prevent state desynchronization and ensure wire-speed route programming
Architecting automated regression workflows with Pytest, PTF, sonic-mgmt, and Ansible integrated into CI/CD pipelines to validate forwarding, congestion, and L2/L3 resiliency
Using packet captures, kernel debug tools, diagnostic logs, Redis telemetry, and line-rate traffic generators for root-cause analysis of system-level anomalies
Leveraging AI-assisted log analysis, LLM coding assistants, and automated RCA scripts to accelerate defect isolation and test automation cycles
Conducting code reviews across C/C++, Python, and Go codebases, mentoring team members, and maintaining high standards of code quality
Acting as a key technical authority and collaborating directly with client architects and silicon vendor engineering groups

Requirements

Proven track record of shipping, qualifying, and hardening production-grade SONiC platforms on physical switch hardware
Expert-level hands-on experience with SWSS, syncd, Redis state databases, and SAI
Ability to isolate complex bugs across NOS application software, SAI wrapper logic, and vendor-proprietary silicon SDKs, driving fixes through vendor engineering channels
Strong hands-on engineering skills in C/C++ and Python within Linux environments, including multi-threading, IPC mechanisms, socket programming, and system calls
Understanding of Layer 2 and Layer 3 networking standards such as BGP, EVPN, VXLAN, VLAN, QoS, RoCEv2, PFC, and ECN
Strong experience with Linux networking internals, kernel drivers, sysfs, dmesg, gdb, perf, tcpdump, and systemd service management
Hands-on experience with Python-based test frameworks, including PTF and pytest
Deep familiarity and working knowledge of the sonic-mgmt repository structure and test suite implementation
Proficiency with containerization tools and workflows, specifically Docker
Practical experience with Ansible for configuration management and orchestration
Hands-on experience building and integrating automated CI/CD pipelines
Good knowledge of English at B2+ level minimum for technical communication, documentation, and vendor discussions

Conditions

Flexible working hours and approach to work: fully remotely, in the office (Warsaw), or hybrid
Agile engineering methodologies with direct ownership of software architecture, system performance, and code quality
Occasional afternoon coordination calls expected due to US and European time zones
Professional growth supported by internal training sessions (Tech Talks) and a training budget
Solid hands-on onboarding designed for an easy start
Ability to change the project within the multi-client portfolio
