What you'll do
- Build and own the integration between Seqera Intelligent Compute and the Seqera Platform
- Own Platform compute environments: let customers set up and run compute across AWS, Azure and GCP, Kubernetes, HPC schedulers, and GPU-enabled executions, and handle the ways those backends differ
- Build against cloud provider APIs and SDKs, and handle partial failures, quota and permission errors, and provider quirks that leak into the product
- Own the billing and pay-as-you-go path: metering usage accurately, keeping usage events and invoices reconcilable, and making the free-user onboarding journey work
- Design data models and APIs that stay consistent across services and releases
- Make failures legible: turn raw provider and scheduler errors into something a user can act on, and add the tests and observability that make the next incident faster to diagnose
- Work directly with the Platform and product teams, and with support on escalations from real customers
- Take design decisions within your scope and document the system so it is not dependent on any one person
What we're looking for
- 4+ years building and operating production backend services, with real ownership of at least one
- Strong in Java and/or Groovy, with Micronaut, Spring Boot or similar
- Real hands-on experience with a major cloud provider's API - provisioning and managing resources programmatically, not just deploying to it
- Have worked with Kubernetes as somewhere workloads actually run
- You care about correctness; ideally you have worked on billing, metering or other systems where wrong data has consequences
- Comfortable designing REST APIs and data models, and keeping integrations working across versions and failures
- Have been accountable for something customer-facing in production
- Comfortable inheriting a system, asking questions, and writing down what was never documented
- Comfortable with ambiguity - you develop hypotheses with limited information, drive work independently, and reach out early to stay unblocked
- We use AI every day and expect engineers to use it extensively; you must be genuinely open to it
Nice to have
- Multiple clouds - hands-on across two or more of AWS, Azure, GCP
- HPC and batch schedulers (Slurm, LSF, PBS, AWS Batch, Google Batch, Azure Batch)
- GPU workloads and GPU-enabled provisioning
- Usage-based billing or monetization platforms (Metronome, Stripe) and pay-as-you-go pricing
- Self-serve or free-tier product work: signup funnels, usage limits, conversion
- Bioinformatics, Nextflow, or scientific computing background
- Observability tooling (Prometheus, Grafana, ELK) and CI/CD ownership
- Some frontend exposure (Angular)
- Open-source contributions
