This is a high-impact, high-ownership role for someone who enjoys building robust systems from the ground up. You'll ensure our scientists, engineers, and executives have a frictionless path to the tools they need - with a leading role in shaping how the Company’s digital foundation is built.

Key Responsibility Areas:

Manage physical and virtual server environments, ensuring high availability, consistent patching, and strong security practices
Optimize cloud environments, manage identity and access, and maintain a strong security posture across the organization
Maintain office and lab network infrastructure - including VPNs, firewalls, switches, and Wi-Fi - ensuring reliable, low-latency connectivity
Build and maintain a thorough knowledge base: clear documentation and infrastructure diagrams that the whole team can rely on
Manage hardware and software lifecycles, including inventory, procurement, and vendor relationships
Administer and maintain our MDM environment: managing device enrollment, compliance policies, and configuration profiles across Windows and macOS

Strong documentation skills - able to translate complex systems into clear diagrams and written guides
Excellent communication skills - comfortable explaining technical issues to both engineers and non-technical stakeholders
A collaborative, low-ego approach: equally comfortable supporting a user with a hardware issue and leading a server migration
Ability to thrive in a fast-moving, high-growth environment where priorities can shift quickly
Experience across multiple cloud platforms (Azure, GCP, AWS, Google Workspace/O365)
Background working in a startup, research, or scientific/engineering environment
Familiarity with compliance frameworks or security standards (SOC 2, NIST, etc.)
