Amazon is seeking a Kernel/Hypervisor Engineer to help develop and improve Firecracker, its lightweight virtual machine monitor used to run secure, fast serverless workloads. The role typically requires strong experience with operating-system kernels, hypervisors, virtualization, Linux, systems programming and languages such as C or Rust. Candidates should understand CPU and memory virtualization, device models, security isolation, performance optimization and low-level debugging. Responsibilities may include designing features, reviewing code, investigating complex production issues, improving reliability and collaborating with engineers across AWS. Strong problem-solving, communication and technical documentation skills are expected, along with the ability to work independently in a technically demanding environment.
Amazon is a global technology and commerce company operating across e-commerce, cloud computing, digital streaming, advertising, logistics and consumer devices. Its cloud division, Amazon Web Services (AWS), provides infrastructure and platform services to businesses, governments and developers worldwide. Firecracker is an open-source virtual machine monitor created by AWS to provide secure, lightweight and rapidly starting micro virtual machines, particularly for serverless and container workloads. Amazon is known for its large-scale engineering challenges, customer-focused culture and emphasis on ownership, innovation and measurable results. Employees commonly work in multidisciplinary teams and may contribute to widely used products and open-source projects. The company offers opportunities across software engineering, cloud infrastructure, security, data, operations and business functions in Ireland.
Ireland offers strong opportunities in software engineering, cloud computing, cybersecurity, pharmaceuticals, financial services and technology consulting, with major employment centres in Dublin, Cork, Galway and Limerick. The culture is generally friendly, informal and community-oriented, with English widely used in workplaces. Ireland provides good access to European travel, a lively social scene and attractive countryside, although housing—especially in Dublin—can be expensive and difficult to secure. Public transport is strongest in larger cities, while a car is useful outside urban areas. Non-EU candidates generally need an employment permit; experienced technology professionals may qualify for a Critical Skills Employment Permit, which can support family relocation and later residency options. EU, EEA and Swiss citizens usually have the right to live and work without a permit. Applicants should confirm current immigration, tax and housing requirements before moving.
