Principal Software Engineer-Database Developer

The Central Engineering - Software team is responsible for developing and improving the software ecosystem around Arm's next generation of applications processors. This frequently means working with processors and other hardware technology not yet available to the public. We work on a range of development platforms, software-modeling, FPGAs and early silicon, sometimes many months before the processors are used in real products.
You will have the opportunity to build upon your existing background, knowledge and expertise, provide performance analysis and optimizations to vital open source databases for the Arm architecture. Your contributions will help drive the improvement of popular databases from both the performance and features perspectives. We seek individuals with exposure and knowledge of every level of the database ecosystem across various components and solutions. If you are similarly passionate about innovative technologies, then we want to hear from you!
Responsibilities:

• Work with Arm internal teams and external partners to identify missing SW blocks and bottlenecks, enable and optimize related database engines on Arm servers.
• Collaborate with internal/external partners to understand enterprise database related requirements on Arm servers.
• Work with open source communities to upstream patches and maintain code.
• Help develop, optimize and deliver the software needed to support Arm's ground-breaking IP.
• Collaborate with other architects/engineers to influence Arm technology.

Required Skills and Experience:

• Proficient C/C++ coding skills, with hands on experience developing server class software.
• Experience working with database engine internals or an equivalent technological area (for example filesystem internals).
• Extensive experience in debugging, profiling and optimizing multi-threading software systems.
• Knowledge of operating system internals, Filesystem, and memory architecture.
• Strong understanding of a computer architecture (not necessarily Arm).
• Experience with open-source project development cycles and contribution processes.

"Nice To Have" Skills and Experience:

• Strong understanding with PostgreSQL or MySQL (or any other database) code base.
• Good understanding of concepts such as CPU pipelines, caches, MMU and NUMA, and how they impact high-level software performance.
• Understanding of I/O and networking and their impact on server-side application performance.

In Return:
We offer a hybrid approach to home and office working to provide an adaptable experience for all employees. We expect some working time to be spent in office, to promote a strong collaborative environment with good team integration but are accommodating to different home working requirements.
