Software Engineer

You will join the MIG Platform Forwarding team, the engine room behind the world’s most robust service provider networks.

As a Software Engineer, you will focus on the hands-on design, coding, and optimization of our forwarding software.

Feature Design & Implementation: Own the 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.

Network Knowledge & Debugging:

• Service Provider Context: Understanding of router deployments in Service Provider networks (Core, Peering).
• Technical Troubleshooting: Ability to debug issues at the component level, including hardware/software interactions and memory management.

Minimum Qualifications:

• 5-7 years of experience in embedded software development for networking products.
• Strong programming skills in C/C++ and scripting in Python.
• Proven knowledge of carrier-grade networking OS and forwarding architectures.
• Experience debugging sophisticated embedded software issues.
• Experience working on tools such as Clearcase, Valgrind, DDTS, GDB, etc.

Preferred Qualifications:

• Experience with IOS-XR or similar carrier-grade network operating systems.
• Knowledge of Internet Protocols (TCP/UDP, IPv4/IPv6).
• Exposure to Networking Protocols (L2/L3, QoS, ACLs).
• Experience with BCM, Sione, Ezchip NPU programming.
• Familiarity with AI/ML tools for software engineering (e.g., Copilot for code, AI for log analysis).
