The application window is expected to close on: 12/30/2026
Job posting may be removed earlier if the position is filled or if a sufficient number of applications are received.
Meet the Team
MIG Platform Forwarding team, the engine room behind the world’s most robust service provider networks. We build the high-performance data plane software that powers IOS-XR platforms, leveraging cutting-edge Silicon One (SiOne) Network Processing Units (NPUs).
Our team operates at the intersection of hardware and software, defining how packets traverse the internet's backbone. We are transitioning into a new era of embedded development, utilizing modern AI-assisted methodologies to deliver features faster and with higher quality.
Your Impact
As a Software Engineer, you will focus on the hands-on design, coding, and optimization of our forwarding software. You will be responsible for delivering high-quality code for complex Layer 2 and Layer 3 forwarding features , , ensuring they extract maximum performance from our NPUs. You will act as a key technical contributor, utilizing modern software practices and AI-driven workflows to streamline development and debugging.
Key ResponsibilitiesFeature Design & Implementation: Own the design and development of specific forwarding features within the IOS-XR platform. Write high-performance, production-grade code for
QOS, Mirroring , Slowpath , OAM, Layer 2 (EVPN, VPLS) and Layer 3 (SRv6, Segment Routing, MPLS) technologies.
NPU Data Plane Programming: Implement data plane logic to optimize packet processing. Translate network protocol requirements into efficient NPU microcode and SDK interactions.
Debugging & Root Cause Analysis: Investigate and resolve complex software defects found during internal testing or customer deployments. Analyze logs, core dumps, and packet traces to distinguish between NPU behavior and software logic issues.
Performance Optimization: Profile and tune code to minimize latency and maximize throughput, ensuring the software meets strict service provider performance metrics.
Modern Development Practices: Actively utilize AI/LLM-based tools for code generation, unit test creation, and static analysis to improve individual productivity and code quality.
Embedded Development: Strong proficiency in C/C++ for high-performance embedded systems. Proficiency in Python for scripting and test automation.
NPU Familiarity: Working knowledge of NPU-based data plane architectures (e.g., Broadcom DNX, Silicon One, or ezChip). Understanding of pipelining, table management, and packet processing flows.
