The journey began a decade ago with Nextflow http://nextflow.io/ — 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. Would you like to be a part of a company with a bigger purpose and make it successful with your own ideas? If yes, keep reading! ## 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 https://docs.seqera.io/platform-cloud/supported_software/fusion/overview (a FUSE filesystem presenting cloud object storage as POSIX), Fusion Snapshots https://docs.seqera.io/fusion/guide/snapshots/ (CRIU-based checkpoint/restore that survives spot-instance reclamation), and Ignite (a container process manager) — with Sched https://docs.seqera.io/platform-cloud/compute-envs/intelligent-compute 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. WHAT WILL YOU FIND WORKING AT SEQERA? - Flexible working hours. - International working environment with more than 25 nationalities. - Passionate & talented team. - Continuous skills development. - Team retreats and bonding activities. - A culture where your opinion is valued and your decisions have a real impact on the industry. - Excitement of a fast-growing startup in a constantly changing environment. ## GREAT BENEFITS - Time off: 23 days for vacations per year, 3 days given by Seqera in December, and the national/public holidays according to your location. - Equity - Private health insurance - Private life insurance - Home office allowance (valued over 1,000 USD) - Subscription to Oliva, Mental Health App - Learning and development budget per year (1,000 USD) ## About Seqera ## Company Overview - **One-liner**: Seqera empowers scientists with modern software engineering and data analysis tools, providing the leading bioinformatics platform built on the open-source Nextflow framework. - **Entity Type**: Private (Series B) - **Headquarters**: Barcelona, Spain - **Founded**: 2018 - **Founders**: Paolo Di Tommaso, Evan Floden ## Core Business - **Primary industry**: Bioinformatics / Life Sciences Software / Scientific Computing - **Target customers**: B2B – Pharmaceutical, healthcare, biotech research firms, and academic institutions - **Mission or purpose statement**: Seqera believes in a future in which scientific tools and open datasets combine to deliver incredible outcomes, empowering scientists to solve today's most complex and essential challenges—from pioneering innovative therapeutics to unveiling the secrets of our universe. ## Products & Services - **Nextflow**: An open-source framework for scalable and reproducible scientific workflows using containers.
