Senior Software Engineer

Identify the root cause of incidents or service degradations through detailed investigation and data analysis.

Develop, validate, and implement mitigation steps.

Prepare and present Incident Learning Reviews (ILRs) and postmortems summarizing the incident timeline, impact, root cause, mitigation, and long-term corrective actions.

Identify regressions, configuration errors, or design flaws contributing to incidents and propose systemic improvements.

File and track repair items (bugs, design changes, automation improvements) with clear quality information that meets the defined bug bar.

Partner with Engineering (SWE) teams to ensure timely resolution and verify the effectiveness of the fixes.

Analyze incident trends to identify recurring issues and drive proactive remediation efforts.

Collaborate with Software Engineering on complex, code-level or architecture-level issues.

Influence reliability and resilience improvements across products and services.

Participate in on-call rotations, ensuring timely response and resolution for incidents within assigned service queues.

Technical curiosity and experience using AI to make individual work or team work more efficient and people more productive. 7+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java or Python.

Intermediate knowledge in networking fundamentals, including knowledge of core protocols such as TCP/IP, UDP, DNS, DHCP, HTTP/HTTPS, and QUIC.

Proven hands-on experience with network troubleshooting and diagnostics tools, including procmon, Wireshark for deep packet inspection and protocol-level debugging.

Intermediate understanding of Windows networking architecture, including network virtualization, Hyper-V networking, and Software-Defined Networking (SDN) integration.

Practical experience with MsQuic for implementing and optimizing QUIC protocol performance and security.

Expertise in high-performance packet processing using XDP (Express Data Path) and programmable networking through eBPF (Extended Berkeley Packet Filter).

with Network Module Runtime (NMR) or similar frameworks for binary containment, rollback, and runtime management of network modules.

Knowledge of rebootless update mechanisms (e.g., hotpatching frameworks) for maintaining networking components without downtime.

Familiarity with open-source networking components and undocked servicing, particularly for MsQuic, XDP, and eBPF ecosystems.

Analytical skills for both operational troubleshooting and code-level investigation of complex networking issues.

Proven ability to collaborate cross-functionally with development, support, and security teams to deliver robust, secure, and scalable enterprise networking solutions.

Demonstrated capability to balance hands-on technical depth with a strategic understanding of networking system design and performance optimization.

Excellent written and verbal communication skills, with the ability to document findings, create knowledge articles, and mentor peers on advanced networking concepts.
