What you'll do
- 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.
What we're looking for
- 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.
- Genuinely open to using AI extensively.
Nice to have
- CRIU / checkpoint-restore / process migration.
- FUSE or other filesystem/VFS work.
- Rust; JVM (Groovy/Java, Micronaut).
- Container runtimes, Docker internals, Kubernetes.
- HPC/Batch (AWS Batch, Google Batch, Azure Batch).
- Applied ML / data engineering (Groundswell); open-source systems contributions.
