• ▹Develop integration modules for modern network operating systems (SONiC, NVUE, Cumulus) and DPU hardware platforms
• ▹Instrument services end to end using OpenTelemetry traces and metrics, performing systematic root-cause analysis across polyglot distributed systems
• ▹Participate in review-gated pull request workflows across Rust, Go and SQL codebases while ensuring high test coverage via mock-driven testing

Requirements

• ▹Primary mastery of Rust (Tokio async runtime, Tonic, Axum, sqlx) and strong proficiency in Go
• ▹Advanced SQL/PostgreSQL fluency, gRPC/Protobuf contract design and schema evolution
• ▹Strong background in async concurrency models, lock-free patterns, distributed state handling and mock-driven testing discipline
• ▹Expertise in datacenter protocols and OS: BGP, MP-BGP, EVPN, VXLAN, L3VNI, route targets and route server design; hands-on experience with SONiC, Cumulus Linux and NVUE
• ▹Deep knowledge of NVIDIA DOCA, Host-Based Networking (HBN), BlueField DPU architectures and the DPF (DOCA Platform Framework) operator model
• ▹Understanding of InfiniBand fabrics, NVLink/NMX-M partitioning and RoCEv2
• ▹Advanced grasp of Linux kernel networking: netlink, network namespaces, routing tables and internal DHCP/DNS service implementations
• ▹Familiarity with cloud and Kubernetes networking: CNI plugins (Calico, Cilium)
• ▹Provisioning and boot infrastructure: PXE/iPXE, UEFI, Secure Boot, measured boot and TPM attestation
• ▹Hardware management: Redfish, IPMI and BMC abstractions across heterogeneous hardware platforms (Dell, Lenovo, NVIDIA reference hardware)
• ▹Linux systems internals: boot chains, systemd, initramfs and BIOS configuration matrices
• ▹Identity and security: PKI, X.509 certificates, TLS, SPIFFE/SVID, Vault, KMS, Keycloak (OAuth2/JWT) and RBAC
• ▹Virtualization: KubeVirt and KVM
• ▹Experience writing custom controllers/operators using kube-rs or controller-runtime with CRD-driven reconciliation loops
• ▹Commitment to test-driven design, writing testable code with mock interfaces for external hardware and network dependencies
• ▹Proven track record of writing crisp architectural specs and engaging in constructive, cross-functional design reviews
• ▹Bachelor's or Master's degree in Computer Science, Computer Engineering or equivalent practical experience
• ▹5+ years of software engineering experience in cloud-native platforms, systems programming, networking or infrastructure automation
