Description du poste

Biomemory is a worldwide pioneer in DNA Data Storage.

We are a well-funded deeptech start-up developing rackable IT servers for Data Centers that use synthetic DNA as a data storage medium.

While this technology is still in its infancy, our DNA-based storage servers aim to handle massive data volumes (Exabytes) with ultra-long retention (>100 years) at an attractive CAPEX and OPEX.

Headquartered in Paris, Biomemory’s mission is to serve the fast-growing global cold storage market.

About the Job

Reporting to the Director of Software Engineering, you will join Atlas Team as a Sysadmin Technician, and you will be in charge of the system and infrastructure operations.

Infrastructure & System Operations

• Maintain system and network infrastructure in operational condition.
• Update and monitor both internal and external systems.
• Manage access requests and maintain proper control over user permissions.
• Map and document the Information System, contributing to a cultural shift from “it works” to “it works and it’s documented.”
• Install and administer external compute resources (e.g. OVH bare metal) in a controlled and reliable manner (using SLURM).
• Conduct security assessment and propose or discuss remediation plans.
• Contribute ideas for new installations, deployments, and automation.
• Simplify and document procedures to improve efficiency and reliability.

Support & Internal Operations

• Manage internal tickets (via GitLab): triage, prioritization, follow-up, and metrics.
• Provide basic user support for workstations (Linux, Windows and macOS).
• Manage user access (provisioning, revocation, monitoring, incident alerts).
• Participate in onboarding and offboarding (hardware setup, account creation, SI overview).
• Manage software licenses and hardware inventory.
• Promote best practices and enhance information security culture.
• Collaborate with Sarah, our Office Manager, on technical vendor relationships (cloud and infrastructure providers).

R&D and Operations

• While this position is primarily focused on managing infrastructure and servers (≈90%), the engineer will also contribute around 10% of their time to R&D efforts.
• This includes supporting the definition of operational procedures for successive versions of our DNA-based data storage system.
• The role is anchored in production infrastructure, but thanks to his/her experience, the person will collaborate closely with the Software team—using their operational expertise to help design and validate our next-generation DNA storage device.
• In short: a full-time infrastructure engineer, structuring and maintaining the system, yet deeply aligned with R&D DNA.

About You

Technical Skills (Required)

• Linux (multi-distribution, strong experience with Debian and Ubuntu)
• Bash scripting, system automation, and administration
• Networking: ARP, IP, TCP, SSH, Wi-Fi
• Virtualization: Proxmox or equivalent
• Storage systems: CEPH, S3, RAID, LVM, partitioning, etc.
• Security: Firewalls (Linux & appliance), VPN
• Boot/BIOS/EFI, Dell rack servers (iDRAC)
• Python and general scripting experience
• Ability to support cross-platform environments (Linux, Windows and macOS)

Nice to Have

• Experience with MDM/IAM (Okta or equivalent)
• Knowledge of Docker, Kubernetes, and cloud platforms (AWS, GCP, or Azure)
• Familiarity with Google Workspace administration

Experience

• At least 5+ years of professional experience in system administration, infrastructure, or DevOps.

Soft Skills

• Flexible, empathetic, patient, and service-oriented (user support mindset)
• Clear communicator, organized, and solution-driven
• Comfortable working in a fast-paced, cross-functional environment

Work Environment

The position is onsite, based at our office located at 5 Impasse Reille in Paris (14 th arrondissement). The workspace combines modern classic offices with advanced laboratory rooms, designed to foster collaboration between computer scientists and biologists. This setup supports our mission to tackle the challenges of DNA synthesis and writing, encouraging interdisciplinary teamwork and innovation.

In 2026, our offices will relocate to a new headquarters in the center of Paris (near Notre-Dame Cathedral). This state-of-the-art facility, under construction, will offer an inspiring and accessible setting, to host our growing team.

Biomemory provides benefits beyond the French regulations, to support the well-being of its employees and enable them to best contribute to the success of the company.
