Note: The job is a remote job and is open to candidates in USA. Mirantis is a Kubernetes-native AI infrastructure company that builds cloud-native platforms for scalable, secure infrastructure. The Senior Software Engineer will develop control plane software for AI infrastructure, integrate datacenter networking and DPU platforms, design APIs and architectures, and support observability, diagnostics, and engineering quality.
Responsibilities
- 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
Skills
- * Language Proficiency: Primary mastery of Rust (Tokio async runtime, Tonic, Axum, sqlx) and strong proficiency in Go
- * Data & APIs: Advanced SQL / PostgreSQL fluency, gRPC/Protobuf contract design, and schema evolution
- * Concurrency & Reliability: Strong background in async concurrency models, lock-free patterns, distributed state handling, and mock-driven testing discipline
- * Datacenter Protocols & OS: 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)
- * 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)
- * Cloud & Kubernetes Networking: OVS and DPDK experience is a plus
- * Provisioning & Boot Infrastructure: Expertise in PXE/iPXE, UEFI, Secure Boot, measured boot, and TPM attestation
- * Hardware Management: Proficiency in Redfish, IPMI, and BMC abstractions across heterogeneous hardware platforms (Dell, Lenovo, NVIDIA reference hardware)
- * Linux Systems Internals: In-depth knowledge of boot chains, systemd, initramfs, BIOS configuration matrices
- * Identity & Security: Practical experience with PKI, X.509 certificates, TLS, SPIFFE/SVID, Vault, KMS, Keycloak (OAuth2/JWT), and RBAC
- * Virtualization: Experience with KubeVirt / KVM
- * Kubernetes Control Planes: Experience writing custom controllers/operators using kube-rs or controller-runtime with CRD-driven reconciliation loop patterns
- * Testing Discipline: Commitment to test-driven design, writing highly testable code with mock interfaces for external hardware and network dependencies
- * Collaborative Architecture: 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
- * Demonstrated participation or maintainership in open-source systems projects is a plus
