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

About the Team

Our engineering team builds next-generation cloud-native bare-metal orchestration platforms for AI neo-cloud environments. We operate on a T-shaped engineering model: while each engineer brings deep expertise in a primary domain every team member maintains practical fluency across neighboring systems. This shared foundation enables rigorous design reviews effective cross-domain code reviews and dependable on-call coverage. Our development is fundamentally based on open-source projects and contributing to them is a major part of our work.

We develop primary control plane software in Rust and Go leverage Kubernetes operators and foster an OpenTelemetry-first operational culture. 

Role Overview

We are seeking a Senior Software Engineer who combines strong software architecture principles with deep technical domain expertise in Datacenter Networking and DPU architectures. Fitting into our T-shaped engineering model you will drive the development of control planes powering high-density high-throughput infrastructure for AI training and inference workloads. Familiarity with automated bare-metal provisioning and lifecycle management is a strong asset.

Core 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.

Qualifications :

• 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). 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.

Universal Requirements 

• 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.

Educational & Experience Baseline

• Bachelors or Masters 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.
