We're a global, remote-friendly team with headquarters in Barcelona and colleagues across the US, UK, and beyond. As we continue to grow, we're strengthening our internal foundations - and that's where you come in. About the roleWe are looking for a Staff Software Engineer to join our Unified Compute team and take technical ownership of the low-level systems that power how scientific workloads run in the cloud.
Our scheduling project (Sched) has gained real momentum, and we need a senior engineer to help build the ecosystem around it to the next level.



The core of this role is deep in the stack — Fusion (a FUSE filesystem presenting cloud object storage as POSIX), Fusion Snapshots (CRIU-based checkpoint/restore that survives spot-instance reclamation), and Ignite (a container process manager) — with Sched as the orchestration layer that ties compute together.
You'll also support adjacent services such as Groundswell (ML-based resource prediction) and Cloudinfo (multi-cloud pricing/metadata). It's a hands-on senior role with strong architectural influence.
What You'll DoDesign, 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.
