About the Role The Security team is building and enhancing a cloud platform for various network security controls and management. Our mission is to develop highly-available and performant distributed systems to provide security at the network level in public clouds, including micro segmentation, L3/4/7 DDoS prevention — spanning VMs, containers, and a wide range of compute substrates. This is a great opportunity for ambitious engineers seeking comprehensive technical growth across four dimensions: Development: Architecting and building distributed systems (highly available microservices) Security: Access control, network security policies, packet filtering, and DDoS prevention Networking: Software solutions across OSI layers and devices, from physical hosts to containers AI: Leveraging LLMs and agentic frameworks to automate security controls, detect anomalies, and enhance threat intelligence Responsibilities Architect and implement distributed systems to deliver network-level security controls across Salesforce's public and private clouds — including network policy management, ACL enforcement, and DDoS/network protection for containers Develop software solutions and microservices supporting network security platforms in public clouds Research and implement new network security solutions for intra- and cross-datacenter network flows Advance and operate security scanning platforms in a full DevOps model Participate in Agile development practices, including daily scrums Drive engineering excellence through code reviews and mentoring junior team members Requirements 6+ years of industry experience, including: 4+ years in SaaS, PaaS, or IaaS software development 3+ years in a high-availability 24/7 environment (cloud platforms a plus) Technical Skills AI Tools: Hands-on expertise using AI tools in software development Network Security: Proven experience building or managing platforms for network security, including: Segmentation, ACLs, DPI, DDoS protection Software tools: iptables, IPsec, VPN, IDS WAF/OWASP protections Networking: Industry-level expertise in one or more of: VM and container network stacks (OpenStack Neutron, Cilium, Romana) Network control planes and agents (Calico, Flannel, Contiv, Contrail, OVN) OSI model and network traffic debugging Networking protocols (TCP/UDP, BGP, DNS, DHCP) Datacenter network architecture — NAT, VXLAN, overlay/underlay Programming: Proficiency in OOP and multi-threaded programming in at least one of: Golang, Java, C++, Python Platform Development: Proven track record designing and coding large-scale PaaS/IaaS systems for public cloud providers (AWS, Azure, GCP) Software Design: Expertise in systems patterns (Client-server, N-tier, Master/Slave, MVC) and API constructions (Swagger, OpenAPI) Operating Systems: Development and software management on Linux (CentOS, RHEL) Security Fundamentals: Strong knowledge of: Authentication/authorization frameworks (SSO, SAML, OAuth) Secure transport (SSL, TLS) Identity management (certificates, PKI) DevOps Mindset: Strong ownership over code — test, monitor, deploy, maintain Communication: Excellent oral and written communication skills Collaboration: Ability to prioritize team success beyond personal contributions Nice to Have Distributed Systems — expertise in any of the following: High-performance, high-availability (99.999%) and self-recoverable systems Control, orchestration, and automation platforms RPC frameworks (Protobuf/gRPC, Thrift, Bond) Consensus and consistency frameworks (Paxos, Raft, strong/eventual consistency) Data-processing systems (Lambda architecture, Kafka, RabbitMQ, ELK) Storage solutions (Cassandra, MongoDB, Hadoop, Redis, Zookeeper) VMs & Containers — hands-on experience with OpenStack, Docker, Kubernetes Full Software Ownership — end-to-end experience across the entire software lifecycle: design → code → unit tests → integration tests → production deployment → ongoing support
