About The Position

As Lead Engineer on the Salesforce Network Software team, you will design and implement the distributed and highly available Software-defined networking infrastructure for one of the largest enterprise applications ever built on the public cloud. Our team is responsible for the mission-critical fabric that enables Salesforce to operate at an unprecedented global scale. You will lead the development of high-performance networking services, with a focus on building a truly multi-substrate, dual-stack (IPv4/IPv6) foundation. A primary building block of this infrastructure is our networking software, enabling self-service, API-driven connectivity across AWS, Azure, and GCP. Your work will replace legacy bottlenecks - like manual routing, IP allocation and static configuration - with a software-defined layer that enables faster deployments and architectural efficiency.

Requirements

6+ years of proven experience designing, developing, debugging, and operating resilient distributed systems that run across thousands of compute nodes in multiple data centers, with a focus on Networking technologies
Expert-level coding in Golang, Python, or C/C++ in a Linux/UNIX environment.
Proven experience building and operating resilient, high-availability services at scale.
Advanced knowledge of IP networking and cloud-native networking primitives.
Experience owning mission critical services, including designing for Disaster Recovery and multi-region failover.
Experience in Agile/Scrum environments with a commitment to Test-Driven Development and high code quality.
Excellent written and verbal communication skills
A related Technical degree required

Nice To Haves

Massive-Scale Mindset: You are excited by the challenge of building infrastructure for an application that serves millions of users across multiple public clouds.
Systems Architect: You view networking as a distributed systems problem, prioritizing self-healing, automation, and API-first design.
L3-L7 Expert: Deep proficiency in the OSI stack, specifically L3 (BGP, IPv4/IPv6 routing), L4 (TCP/UDP performance), and L7 (TLS, DNS, DDOS prevention/mitigation).
Operational Leader: Experience owning mission-critical services where downtime is not an option, with a strong focus on telemetry and data-driven reliability.

Responsibilities

Design and operate mission critical networking services that power Salesforce’s massive public cloud footprint, ensuring they are resilient to regional failures and support seamless Disaster Recovery (DR).
Lead the development of critical infrastructure services, including next-gen Dual-Stack IPAM, ensuring automated, self-service IP provisioning across all cloud substrates.
Transform how our services connect by reducing reliance on complex intermediaries, moving toward a streamlined, software-defined network fabric.
Drive the adoption of IPv6-native and dual-stack architectures, ensuring the IPAM and routing layers are ready for the next decade of cloud growth.
Leverage and contribute to cutting-edge projects to build observability and control into the heart of the network.
