Seqera exists to advance science for everyone through software

We provide software for scientists solving today's most complex and important challenges from pioneering innovative therapeutics to unveiling the secrets of our universe. The journey began a decade ago with Nextflow — open software that helps over 100,000 global scientists analyze and process data, with more power and flexibility than ever before.

Today, Seqera consolidates fragmented data and diverse computing resources into a unified platform. Our modern biotech stack is trusted by over 150 leading life sciences organizations. Empowered with modern software engineering, organizations conduct science faster, on larger datasets, and with more confidence. Seqera accelerates discoveries in an open world.

About the role

We 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 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.

About you

• 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.

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.
