About the role

The Search and Storage team is responsible for the infrastructure that powers all of Sentry's time-series data and searching capabilities across billions of events with sub-second latency. We started this initiative by building Snuba, the primary storage and query service for Sentry's event data powered by ClickHouse, and we're now looking to provide even more visibility and reporting on the terabytes of data that our users send us. The storage sub-team is specifically concerned with ingesting the input data (thousands of events per second) that come from our customers into ClickHouse.

In this role you will

• Architect and implement scalable Kafka consumption pipelines that process thousands of input events per second
• Guide product engineering teams as they work to design ClickHouse and other database schemas for new features
• Design data migrations for product features that have scaled beyond the abilities of PostgreSQL, helping teams move their data to ClickHouse
• Learn and aid in learning by attending and leading discussions about scaling technologies for time-series data storage
• Help our SRE team manage clusters of shared, replicated distributed databases

Arm Machine Learning (ML) Compilers team is looking for a software engineer who would build a range of innovative compiler solutions for a variety of markets.

You will apply your experience and insight within this domain to craft and optimise compilers for machine learning networks that target range of Arm’s CPUs, GPUs and NPUs.

If you are interested in this opportunity, make sure to apply soon! We look forward to receiving your application and welcoming you to Arm. You could be joining our highly motivated compiler team and have a marked impact on both strategy and implementation!

Responsibilities:

• Build, extend and collaborate on innovative ML compilation software projects, such as Apache TVM and IREE
• Work with other groups in Arm to expand support for Arm architecture and ecosystem

Do you want to help build tomorrow's solutions? This is an excellent opportunity to work in the Architecture and Future Technologies team in Arm's Development Solutions Group in Cambridge, UK. We investigate and prototype new tooling technologies to support Arm's evolving architecture and product roadmap. We find out how to help new features land successfully in the software ecosystem, and we feed back to architects and hardware design teams.

Responsibilities:

We create innovative solutions that help Arm's partners and the wider ecosystem run software efficiently on Arm. We also keep track of external trends in programming languages and frameworks, and seek to understand how they will impact on our development tools and on our architecture. Some of our investigations lead to new products or product features, or to open-source tools. Our team also regularly benefits from internships and graduate secondments, and there are opportunities for more experienced staff to supervise these.

The GPU group writes the layer of the driver that implements the popular GPU compute APIs, such as OpenCL and Vulkan which provide massively parallel execution of general-purpose code on GPUs. Our many customers have performance-critical GPU compute use cases that include machine learning (ML), image processing & computer vision (CV), video encoding and decoding. Mobile devices are highly constrained environments, and our challenge is to provide this sophisticated functionality, while improving both dependability and efficiency. If you want to develop your skills and understanding in these technologies, this is the opportunity for you.

Responsibilities:

Performance analysis and optimization investigations of various benchmarks, analysing the results and identifying optimisation opportunities in the driver, compiler, and hardware architecture. New benchmarks and technologies will be added and evaluated for competitive performance comparisons. The team also assesses the performance of future GPUs for the latest use cases. You will work in a Linux environment, working on Arm-based targets including models, FPGAs and silicon from our partner companies (thereby covering past, present and future generations of our designs)

As a member of an Agile team, you will have the chance to try your hand at different aspects of our work. Engineers grow their expertise through in-house and externally hosted training, and through peer code reviews. You will be working closely together with our community of engineering teams across Arm’s European design centers.
