MatX is seeking System Software Engineer to join our team as we create best-in-class silicon for high-performance and sustainable GenAI. Successful candidates for these roles will be responsible for delivering performant and functionally accurate silicon for MatX products across compute, memory management. High-speed connectivity and other key technologies.
The MatX host system software team owns everything that makes our AI silicon and systems usable: from Linux kernel drivers up through node and cluster management. The team also co-owns the BMC/OpenBMC firmware stack, with dedicated firmware engineers, so host software and out-of-band management are designed together rather than bolted together. We're looking for self-driven engineers who can take a hardware spec and a register map and just start building - prototype drivers, low-level utilities that talk directly to the chip, daemons, and tooling - with minimal hand-holding. Each engineer on this team has a primary focus area, but ownership of overlapping components is shared, and you should expect (and want) to venture across the stack.
What You'll Do Here- Design and build the node-level management plane for MatX's AI systems: expose node health, inventory, telemetry, and control operations through HTTP/REST endpoints (e.g., Redfish-style or custom APIs)
- Design and implement cluster management solutions and failover algorithms to minimize downtime
- Build the management CLI utilities that operators and internal engineers use daily - interacting with the on-node management and telemetry daemons to query state, run diagnostics, update firmware, and recover devices
- Partner with our BMC firmware engineers to present unified management and observability across in-band and out-of-band paths - so operators see one coherent node, whether data comes from the host daemons or the BMC (e.g., unified Redfish-style views, firmware update orchestration across host and BMC, and recovery flows that work even when the host is down)
- Extend node-level capabilities to cluster level: fleet-wide health aggregation, device inventory, alerting hooks, and integration points for our customers' own fleet-management systems
- Get hands-on with the low-level stack: you'll regularly need to drop below the API layer - into the telemetry daemon, driver interfaces, or raw device access utilities - to prototype, debug, or unblock yourself
- Build tooling and automation for managing lab systems during bring-up: provisioning, test orchestration, regression monitoring
- Define the software contracts between the on-node daemons, the BMC stack, and the management layer - shared-ownership boundaries you'll co-design
- Debug production-grade issues spanning management APIs, daemons, kernel drivers, BMC firmware, and hardware
- Help shape what "manageable at scale" means for a new hardware platform, from single node to full rack to cluster
Who You Are- BS or higher in Computer Science, Electrical Engineering, or equivalent practical experience, with 8+ years in systems software - this is not a pure web-services role; deep low-level systems experience is required
- Strong hands-on Linux systems development experience, including low-level userspace software; comfortable reading and debugging kernel driver and daemon code
- Strong programming skills in C plus a systems language suited to services and tooling (Go, Rust, C++, and/or Python)
- Experience designing and building HTTP/REST APIs and CLI tools for hardware or infrastructure management
- Solid understanding of how the pieces underneath your APIs actually work - device drivers, telemetry paths, PCIe device behavior, BMC-managed subsystems - and the instinct to go look when something misbehaves
- Experienced debugging across API, daemon, kernel, firmware, and hardware boundaries
- Comfortable working with firmware engineers to align host-side and BMC-side management capabilities behind common interfaces
- Self-driven and pragmatic: able to stand up a working management endpoint against brand-new hardware with minimal specification
Bonus Points If You Have- Experience with Redfish, OpenBMC, gNMI, IPMI, or other datacenter hardware management standards
- Cluster/fleet management experience for GPU or accelerator infrastructure
- Experience with hardware bring-up, lab automation, or manufacturing/qualification test infrastructure
- Familiarity with firmware update orchestration, secure boot, or attestation flows
