About the role

Key responsibilities & impact

Design, build, and own low-level systems across Fusion, Fusion Snapshots, Ignite, and Sched.
Write reliable, well-tested code primarily in Go and C, with Rust and JVM (Groovy/Java, Micronaut) where the codebase calls for it.
Work close to the OS: FUSE filesystems, Linux namespaces, CRIU checkpoint/restore, process supervision, signal handling, static musl builds.
Tackle multi-cloud orchestration and scheduling: provider abstractions (AWS, Azure, GCP), instance selection, autoscaling, spot-instance fault tolerance, durable async queues.
Drive performance engineering — chunked I/O, multi-level caching, buffer pools, bandwidth management.
Set technical direction and raise the standard for testing, observability, and operational excellence.
Mentor teammates and help onboard new engineers.

Requirements

What you’ll need

Deep experience building production-grade systems software, with technical ownership at Staff level.
Strong in Go and comfortable in C (or C++), close to the operating system.
Solid Linux internals — filesystems, namespaces, processes, signals, networking — and comfortable debugging at that level.
Built distributed and/or cloud-native systems and understand the failure modes of running across multiple clouds.
Write simple, well-structured, well-tested code; optimize for clarity and debuggability.
Comfortable with ambiguity and driving work independently.
We use AI every day and expect engineers to use it extensively — you don't need to be an expert, but you must be genuinely open to it.
