Bioptimus is hiring a Senior Platform Engineer - Cloud & Developer Experience

Responsibilities

  • Own the cloud foundation. Design, build, and own our AWS architecture and the Terraform/IaC that defines it — accounts, networking, identity, core services — as reproducible, reviewed, version-controlled infrastructure.
  • Build the self-service platform. Create the golden paths and internal developer-platform tooling that let engineers and researchers provision, deploy, and ship with minimal friction and sensible guardrails.
  • Own CI/CD and the deployment fabric. Build and maintain the pipelines and deployment substrate — including the path that gets our models and SDK into cloud and on-prem/customer environments reliably.
  • Engineer security and networking into the platform. Make security and a sound network a property of the paved road, not a checklist: IaC for access management and access control, secrets management, least-privilege defaults, network segmentation and private connectivity — so doing the right thing is the easy thing.
  • Set the standards. Create, influence, and review the architecture, standards, and processes the platform team works to; decide, with a product lens, what becomes platform versus what stays an experiment.
  • Make it observable and cost-aware. Build the metrics, alerting, and cost visibility that keep the platform reliable and economical as scale grows.
  • Support research at scale. Bring platform know-how to research workflows and help them self-serve — supporting scale, not owning research-infra execution.

Requirements

  • Proficiency in AWS — hands-on production experience designing and running cloud infrastructure for real workloads.
  • Proficiency in Infrastructure-as-Code — Terraform in production (configuration-as-code such as Ansible a plus); you treat infrastructure as reviewed, reproducible software.
  • Proficiency in Kubernetes and containers — hands-on with container orchestration and the components around it.
  • Strong CI/CD and developer-experience instincts — GitHub Actions, ArgoCD/Flux or equivalent; you've built pipelines and internal tooling that other engineers depend on.
  • Security-engineering capability — you implement access control, secrets, and least-privilege in code, and reason about the security posture of what you build.
  • Strong networking — hands-on with cloud and hybrid networking (VPC design, segmentation, private connectivity, DNS, load balancing, ingress/egress control). You treat the network as a first-class security and reliability surface — this complements the security-engineering work directly.
  • A platform-as-a-product mindset — you can tell what deserves to be a productized paved road versus a script, ship opinionated defaults, and enable teams rather than gate them.
  • Solid software engineering — Python, Go, or a comparable language, with sound engineering practices.

Nice to Have

  • Experience with cloud GPU compute for ML training; exposure to HPC (SLURM, InfiniBand, bare-metal GPU) — useful for understanding research workflows even though we run cloud-first.
  • Modern observability stacks (Grafana, Prometheus/VictoriaMetrics, Loki).
  • Experience in pharma, biotech, healthcare, or another regulated-data environment.
  • Exposure to SOC 2, ISO 27001, or GDPR controls (we build the engineering so certification is easy later).
  • Experience contributing to or maintaining open-source projects.
  • Start-up or fast-scaling environment, with a high degree of ownership.

Additional Information

  • CV must be submitted in English
  • Remote-friendly working
  • Flexible working

About company
Bioptimus

Bioptimus is building the first universal AI foundation model that connects biology at its different scales – from molecules to cells, tissues, and whole organisms. The company trains foundation models natively across modalities and scales to learn the dynamics of human biology and predict what happens next.

Its models are designed to jointly learn from multimodal data spanning histology, spatial transcriptomics, genomics, and clinical records. This enables deeper biological insights for drug discovery, biomarker identification, indication expansion, and clinical trial design.

Bioptimus powers research at over 1,000 institutions worldwide, including 16 of the top 20 pharma companies. Its models are benchmarked as the #1 performing in independent evaluations and are used in peer-reviewed research and real-world applications.

The company is driven by a world-class team with deep expertise in machine learning and biology, originating from institutions like Google Brain, Google DeepMind, MIT, ETH Zürich, and more. 60% of the team hold PhDs, and it is guided by a scientific advisory board at the frontier of AI and biology.
