Senior Rust Engineer - AI Infrastructure / Bare Metal / Networking

Mirantis builds open standard, bare-metal infrastructure platforms for modern AI clouds and high density GPU clusters. We focus on the low level orchestration layer - connecting bare metal compute, programmable network fabrics, and control planes to run scale out AI training and inference. We are looking for a Senior Rust Engineer with deep Rust mastery to own the architecture and execution of our core control plane microservices.

The Engineering Challenge:

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

Your Profile:

• Language Proficiency: Primary mastery of Rust (Tokio async runtime, Tonic, Axum, sqlx) and proficiency in Go or C/C++
• Datacenter Protocols & OS: Expertise in BGP, MP-BGP, EVPN, VXLAN, L3VNI, route targets, and route server design.
• DPU & Fabric Ecosystem: Deep knowledge of NVIDIA DOCA, Host-Based Networking (HBN), BlueField DPU architectures, and the DPF (DOCA Platform Framework) operator model (BFB, DPUSet, DPUNode CRDs).
• High-Performance Interconnects: Understanding of InfiniBand fabrics, NVLink / NMX-M partitioning, and RoCEv2.
• Linux Kernel Networking: Advanced grasp of Linux netlink, network namespaces, routing tables, and internal DHCP/DNS service implementations (the project ships its own services).
• Cloud & Kubernetes Networking: Familiarity with CNI plugins (Calico, Cilium).
• Low-Level Infrastructure Experience: Hands-on work in bare-metal provisioning (PXE/iPXE, Redfish/BMC), DPU architectures, datacenter networking (BGP, EVPN, VXLAN), or native K8s controllers.

Engineering Culture:

• Upstream-First Development: We build on open standards, and contributing code back to upstream projects is a core expectation, not a side activity
• Low-Level Systems Focus: Solve non-trivial state reconciliation, kernel networking, and hardware interface challenges at the core platform layer
• Cross-Functional Fluency: Deeply own your core focus while maintaining the practical knowledge needed to review code, evaluate specs, and collaborate across adjacent systems (kernel networking, storage, GPU fabrics).

Offer:

• Work with an established Silicon Valley leader in the cloud infrastructure industry;
• Be a part of cutting-edge, open-source innovation;
• Thrive in the high-energy environment of a young company where openness, collaboration, risk-taking, and continuous growth are valued;
• Professional development and training;
• Attend conferences and working groups;
• Company outings, happy hours, hackathons, and tech talks;
• Receive a competitive compensation package with a strong benefits plan.
