Bull is also thousands of engineers, researchers and passionate tech people shaping the future of high‑performance computing, AI, and quantum technologies.

Every day, our teams push the boundaries of what is technologically possible – from next‑generation HPC architectures to exascale supercomputers – supported by world‑class R&D, more than 1,600 patents, and unique end‑to‑end capabilities spanning hardware design, software engineering, data science and quantum research.

We are a people‑centric, innovation‑driven company, where collaboration spans Europe, the Americas and India. We share a common vision of a responsible and sustainable innovation that delivers concrete impact for our customers.

Bull’s High-Performance Computing (HPC), Artificial Intelligence & Quantum Business Unit is seeking a Hybrid Hardware & Software Support Engineer to join our HPC Services team. This is a highly visible, customer‑facing operational role supporting advanced HPC infrastructures in the UK.

You will work across computing, storage, and networking layers, ensuring the deployment, stability, and performance of large-scale Linux‑based systems. While prior HPC experience is an advantage, it is not mandatory - strong Linux and infrastructure engineers eager to grow into HPC & AI are encouraged to apply.

• Install, configure, and integrate HPC cluster components (compute, storage, networking).
• Perform system installation, initial configuration, and operational readiness checks.
• Apply patches, updates, and conduct routine maintenance activities.

• Act as the primary technical contact on‑site.
• Communicate effectively regarding incidents, planned maintenance, and system status.
• Build trusted relationships with customer technical stakeholders.
• Represent Bull professionally in sensitive and high‑profile environments.

What you must know to perform the role successfully:

• Strong Linux expertise (Red Hat and/or Debian‑based environments)
• Solid understanding of enterprise server hardware (CPU, memory, storage, diagnostics)
• Scripting skills in Bash and/or Python
• Strong networking fundamentals (TCP/IP, routing, switching, security basics)
• Hands‑on experience with infrastructure deployment, configuration, and maintenance
• Excellent troubleshooting and analytical abilities
• Proactive mindset and ability to work independently

Valuable, but not mandatory:

• Experience with HPC clusters
• High‑speed networking (40/100
  
  GbE, Infini Band)
• Storage systems (Ceph, SAN/NAS)
