About the Role

We are seeking a Senior Software Engineer to drive the development of control planes powering high-density, high-throughput infrastructure for AI training and inference workloads. This role involves combining strong software architecture principles with an understanding of Datacenter Networking and DPU architectures, fitting into a T-shaped engineering model.

Responsibilities

  • Design, build, and maintain production-grade control plane microservices, custom Kubernetes operators, and robust reconciliation engines in Rust and Go.
  • Author clear Functional (FR) and Non-Functional Requirements (NFR), architectural specs, system sequence diagrams, and clean gRPC/Protobuf and REST API schemas.
  • Develop custom integration modules and integrations for modern network operating systems (SONiC, NVUE, Cumulus) and DPU hardware platforms.
  • Instrument services end-to-end using OpenTelemetry (OTel) traces and metrics, performing systematic root-cause analysis across polyglot distributed systems.
  • Participate in rigorous, review-gated pull request workflows across Rust, Go, and SQL codebases while ensuring high test coverage via mock-driven testing.

Requirements

  • 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 or systems programming.
  • Primary mastery of Rust (Tokio async runtime, Tonic, Axum, sqlx) and proficiency in Go (secondary).
  • Strong background in async concurrency models, lock-free patterns, distributed state handling, and mock-driven testing discipline.
  • gRPC/Protobuf contract design (via tonic/prost) and schema evolution (using zero-copy serialization and compile-time type generation).
  • Experience writing custom controllers/operators using kube-rs with CRD-driven reconciliation loop patterns.
  • Commitment to test-driven design, writing highly testable code with mock interfaces for external service dependencies.
  • Proven track record of writing crisp architectural specs and engaging in constructive, cross-functional design reviews.
  • Advanced SQL / PostgreSQL fluency.
  • Expertise in BGP, MP-BGP, EVPN, VXLAN, L3VNI, route targets, and route server design.
  • Hands-on experience with SONiC, Cumulus Linux, and NVUE (featuring a first-class NVUE client).
  • Deep knowledge of NVIDIA DOCA, Host-Based Networking (HBN), BlueField DPU architectures, and the DPF (DOCA Platform Framework) operator model (BFB, DPUSet, DPUNode CRDs).
  • Understanding of InfiniBand fabrics, NVLink / NMX-M partitioning, and RoCEv2.
  • Advanced grasp of Linux netlink, network namespaces, routing tables, and internal DHCP/DNS service implementations.
  • Familiarity with CNI plugins (Calico, Cilium).
  • Expertise in PXE/iPXE, UEFI, Secure Boot, measured boot, and TPM attestation.
  • Proficiency in Redfish, IPMI, and BMC abstractions across heterogeneous hardware platforms (Dell, Lenovo, NVIDIA reference hardware).
  • In-depth knowledge of boot chains, systemd, initramfs, BIOS configuration matrices.
  • Practical experience with PKI, X.509 certificates, TLS, SPIFFE/SVID, Vault, KMS, Keycloak (OAuth2/JWT), and RBAC.
  • Experience with KubeVirt / KVM.
  • Demonstrated participation or maintaining open-source systems projects.
