Youll build language-independent infrastructure that isolates workloads protects credentials and enforces security controls across multi-tenant environments.

• Build and operate a transparent sidecar proxy that intercepts outbound vendor API calls enforces credential and compliance policies and records tamper-evident audit events

• Implement process-isolation controls using Linux users and permissions namespaces cgroups ptrace restrictions protected memory and explicit credential cleanup

• Evaluate and implement sandboxing approaches using technologies such as gVisor Firecracker WebAssembly runtimes or Unix-domain-socket isolation

• Design infrastructure that enforces workload and customer boundaries across large numbers of isolated execution environments

• Evaluate and integrate workload identity and attestation technologies such as SPIFFE and SPIRE

• Implement secure workload startup sequencing including KMS access token preparation network-rule installation and readiness signalling

• Improve the performance observability reliability and failure recovery of the execution and isolation layers

• Partner with Platform Security and Backend Engineering teams to define interfaces investigate production issues and deploy platform improvements

• Experience developing production systems software using Go Rust C or C

• Experience working with Linux internals including namespaces cgroups netfilter or iptables sockets and process lifecycle management

• Experience implementing or operating at least one sandboxing or workload-isolation technology such as gVisor Firecracker WebAssembly containers or micro virtual machines

• Experience building networking infrastructure involving TCP/IP transparent proxying or TLS termination and origination

• Experience implementing process isolation privilege separation protected credential handling or related operating-system security controls

• Experience building or operating multi-tenant container sandbox or virtual-machine isolation infrastructure

• Experience with SPIFFE SPIRE or another workload identity and attestation framework

• Experience integrating AWS KMS Azure Key Vault GCP Cloud KMS or similar key-management services

• Experience working on endpoint security EDR zero-trust networking or infrastructure security products

• Experience with Kubernetes container-runtime internals or managed container platforms

• Experience with Temporal or another durable workflow execution platform
