Platform Engineer (Lab Infrastructure / DevSecOps)

We are looking for a Platform Engineer with 7+ years of experience to design and secure the infrastructure that runs the world's fastest DNA sequencing company. This is a DevSecOps role with real on-prem work. You'll build the networks, compute clusters and security that move petabytes of sequencing data across 10 labs and 200+ robots, and you'll also own a serious AWS footprint. We want a hands-on tinkerer from a high-growth startup who architects solutions instead of just maintaining them.

What will you be doing?

• Design and scale lab networking and on-prem GPU compute and storage that stream petabytes of sequencing data
• Build and automate our custom pfSense/MikroTik network from scratch with Terraform, Ansible and GitHub Actions. The Sr. IT Engineer then runs it day to day from runbooks
• Own security engineering: set up firewalls, protect our robot fleet, red team and pen test our web infra (including with AI agents), manage vulnerabilities and handle incident response
• Design and run secure AWS infrastructure (VPC, IAM, containers) and connect it to our on-prem labs
• Help new labs launch faster as Plasmidsaurus grows across all of genomics

Key Requirements

• 7+ years in platform, infrastructure, systems or security engineering (DevSecOps with on-prem experience)
• Has worked with physical infrastructure that mattered, such as labs, factories, robotics, hardware startups or data centers. Pure SaaS experience isn't enough
• Strong AWS skills plus infrastructure as code (Terraform, Ansible, CI/CD) and Python/Bash
• Deep networking knowledge (routing, VLANs, firewalls, VPNs). Has designed networks, not just clicked through vendor dashboards. pfSense/MikroTik strongly preferred
• Has spent most of their career at high-growth, early-to-mid-stage startups, ideally as the first hire in their area. No big-company-only backgrounds
