Network Software Engineer ($250K - $300K + 0.1% - 0.5% Equity) at Blaxel

Network Software Engineer

Architect and build the high-performance networking foundation for the first AI-native cloud. You will design a next-generation SDN fabric using Rust and Go, spanning ultra-high-performance dataplanes and distributed control-plane services. This role is critical for scaling a platform already processing 1.5M+ daily requests for top AI startups.

Why this role is remarkable:

• Build cloud primitives from scratch rather than just gluing existing services together, directly impacting the performance of the first serverless engine optimized for agentic AI.
• Join a high-growth startup that recently secured a $7.3M seed round led by First Round Capital, working at the intersection of systems engineering and the AI revolution.
• Work on a global, bare-metal networking stack that handles multi-million flow tables and sub-millisecond latencies, pushing the boundaries of what traditional clouds can achieve.

What you will do:

• Architect and implement high-performance dataplanes for Blaxel's VPC using VPP, DPDK, eBPF, XDP, and Rust for extreme throughput.
• Build and extend distributed control-plane systems in Go and Rust, including IPAM, L2/L3 routing, and global traffic routing services.
• Design and operate networking workloads on bare-metal clusters with large-scale IPv6-only addressing and deep observability instrumentation.

The ideal candidate:

• Possesses 3+ years of experience in systems engineering, networking, or infrastructure software with a deep understanding of the full networking stack.
• Demonstrates strong proficiency in Rust, Go, or both, with a passion for memory safety, concurrency, and low-level performance tuning.
• Has hands-on experience with modern networking technologies like DPDK, eBPF, or XDP and a thorough understanding of IPv6 and BGP/ECMP routing.
