Principal Hypervisor Engineer in Cambridge

At HP Wolf Security, we're redefining endpoint protection through hardware-enforced security and virtualization-based isolation. We are looking for an experienced Principal Hypervisor Engineer to join our engineering team in Cambridge, where you'll play a key role in designing and evolving the low-level technologies that underpin our security platform.

Working at the intersection of hardware, firmware and operating systems, you'll help develop the hypervisor technologies that isolate threats from the host environment, enabling users to browse, open documents and run applications securely without compromising productivity. You'll contribute to the design and implementation of high-performance virtualization components, memory management, device emulation and system software that operate across modern x86 platforms.

• Design and implement all aspects of system level software such as VMM/hypervisors, operating systems, device drivers and PC firmware.
• Work on new projects as well as provide support and improvements for existing components.
• Analyse and debug problems at the cross-section of hardware, firmware and software.
• Provide solutions for macro and micro verification of the developed components.
• Take ownership of large functional areas such as memory manager or networking subsystem.
• Provide performance improvements for existing solutions.
• Provide engineering support for customer issues, this may require remote or on-site problem analysis and direct collaboration with a customer.
• Provide efficient designs aligned with business needs.
• Collaborate with other development and management teams to provide solutions that fit into existing constraints as well as provide leadership when such constraints need to be changed.

As part of a highly skilled engineering team, you'll help solve complex technical challenges, scale our virtualization platform for future products, and shape the next generation of HP Wolf Security's isolation technology used by millions of endpoints worldwide.

• Expert understanding of modern computer architectures with focus on x86-64 architecture and PC platforms.
• Expert understanding of virtualization technologies, including hardware assisted virtualization (both VT-x and AMDV) and auxiliary technologies such as IO-MMU.
• Expert understanding of modern operating systems (Windows and Linux).
• Experience with building efficient memory manager solutions for virtualization products.
• Experience with building efficient nested virtualization products.
• Experience in building CPU instructions emulators.
• Hands-on experience developing PC platform components such as xHCI controllers, PCI, AHCI, ACPI, PS/2, etc., device virtualization and emulation experience is a plus.
• Reverse engineering experience of closed-sourced systems such as Hyper-V and Windows kernel.
• Hands-on experience with building WHP based solutions.
• Strong debugging and analytical skills.
• 5+ years of experience in kernel and device driver development in Linux or Windows.
• 5+ years of experience developing system software in C and x86 assembler.

• Understanding of ARM64 architecture.
• Experience with Microsoft Windows Hypervisor Platform.
• Deep understanding of components in the OSI networking model with emphasis on TCP/IP protocols.
• Bachelor’s Degree in Computer Science or equivalent preferred.

This role is based in HP’s Cambridge office under a hybrid working arrangement, with a minimum requirement to be onsite three days per week. As a people-focused senior role, regular in-person collaboration is encouraged.

HP has invested in a new, modern site, including ergonomic workspaces and well stocked kitchen facilities that included a wide selection of coffee.

HP Wolf Security is central to HP’s strategy in the PC market, with security designed into hardware, firmware, and software. This integrated approach enables HP to differentiate through built-in, enterprise-grade protection and manageability. This role sits at the heart of that strategy, helping deliver the tools that allow customers to deploy, manage, and trust secure PCs at scale. The primary focus of the HP Wolf Security team is developing cyber security solutions to protect our customers' devices and data.

The digital threat landscape is ever-changing and as the cyber security industry reacts and adapts to changes, so too do the malware authors. Our unique micro-virtualization technology ensures that customers are protected from even the most bleeding edge cyber security threats. That micro-virtualization technology forms a key pillar in a wider cyber security suite that we're actively developing.

Our history: Inspired by the isolation principles of traditional virtualization, our team known then as Bromium, created a game-changing technology called micro-virtualization to protect end users against advanced malware. Every task the user performs, such as opening a document or clicking on a link, is isolated in its own micro-VM, with access to just the resources required for that task, and existing just for the life of the task. Protection is thus provided through isolation, without relying on detection, hence reliably defending the user from polymorphic and even zero-day malware. Bromium was acquired by HP Inc on 19 September 2019 forming HP Wolf Security.
