Rust Senior Software Engineer – Bare Metal as a Service & Datacenter Networking

Description

The team builds cloud-native platforms that orchestrate bare-metal servers for AI neo-cloud environments.

Each engineer has deep skill in one main area and working knowledge of neighbouring systems, which supports solid design reviews, useful cross-domain code reviews and reliable on-call cover.

Most of the work is built on open-source projects, and contributing to them is a large part of the job.

Primary control plane code is written in Rust and Go, using Kubernetes operators, with OpenTelemetry-first observability.

The role centres on control planes for dense, high-throughput infrastructure serving AI training and inference, combining software architecture with datacenter networking and DPU expertise.

The company is a Kubernetes-native AI infrastructure firm, part of a larger group, and is still a young company. Its engineers help large enterprise customers adopt next-generation cloud technology.

Responsibilities

• Build and maintain production-grade control plane microservices, custom Kubernetes operators and reconciliation engines in Rust and Go.
• Write functional and non-functional requirements, architecture specs, system sequence diagrams, and gRPC/Protobuf and REST API schemas.
• Build integration modules for modern network operating systems such as SONiC, NVUE and Cumulus, and for DPU hardware platforms.
• Instrument services end to end with OpenTelemetry traces and metrics, and run structured root-cause analysis across distributed systems in several languages.
• Take part in strict, review-gated pull requests across Rust, Go and SQL, and keep test coverage high with mock-driven tests.

Requirements

• Expert Rust skills, including Tokio, Tonic, Axum and sqlx, plus strong Go.
• Advanced SQL and PostgreSQL, gRPC/Protobuf contract design, and schema evolution.
• Strong grasp of async concurrency, lock-free patterns, distributed state handling and mock-driven testing.
• Expertise in BGP, MP-BGP, EVPN, VXLAN, L3VNI, route targets and route server design.
• Hands-on experience with SONiC, Cumulus Linux and NVUE, where the NVUE client is first-class.
• Deep knowledge of NVIDIA DOCA, Host-Based Networking (HBN), BlueField DPU architecture, and the DPF operator model (BFB, DPUSet and DPUNode CRDs).
• Understanding of InfiniBand fabrics, NVLink and NMX-M partitioning, and RoCEv2.
• Advanced understanding of Linux netlink, network namespaces, routing tables, and the internal DHCP and DNS services the project ships.
• Familiarity with CNI plugins such as Calico and Cilium.
• OVS and DPDK experience is a plus.
• Expertise in PXE/iPXE, UEFI, Secure Boot, measured boot and TPM attestation.
• Proficiency with Redfish, IPMI and BMC abstractions across Dell, Lenovo and NVIDIA reference hardware.
• In-depth knowledge of boot chains, systemd, initramfs and BIOS configuration matrices.
• Practical experience with PKI, X.509, TLS, SPIFFE/SVID, Vault, KMS, Keycloak (OAuth2/JWT) and RBAC.
• Experience with KubeVirt and KVM.
• Experience writing custom controllers or operators with kube-rs or controller-runtime, using CRD-driven reconciliation loops.
• Familiarity with automated bare-metal provisioning and lifecycle management is a strong asset.
• Commitment to test-driven design, with mock interfaces for external hardware and network dependencies.
• A track record of writing clear architecture specs and taking part in constructive, cross-functional design reviews.
• A 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.
• Open-source project participation or maintainership is a plus.
