As part of the Infrastructure Solutions team, the Cluster Architect is the tip of the spear leading Radiant's new GPU deployments. The Cluster Architect contributes to the technical strategy, reference architecture, and governance standards underpinning Radiant's GPU compute platform. They translate the high-level designs provided by the Customer Success organization into fully operational supercomputers. In conjunction with the Datacenter Engineering team, they lead the definition of the low-level design of upcoming high-performance computing (HPC) and artificial intelligence (AI) infrastructure deployments.

You must be a solution finder, able to adapt to evolving technology and customer requirements, and be ready to handle scale. The right person for this role will be technically focused and detail-oriented, and able to work with the broader team to successfully deliver some of the world's largest supercomputers at a rapid pace with precision. It is critical to document each step of the process to enable effective communication with internal and external stakeholders.


What you'll do

  • Engage with key stakeholders (such as the Program Management Office, Data Center Engineering, Solutions Engineering and Infrastructure Operations teams) and translate inputs into Radiant's reference architecture and low-level designs blueprints.
  • Remain abreast of technology advancements and roadmaps with key vendors in the space.
  • Lead the low-level design of high-density AI supercomputer systems (compute, interconnect, storage, management).
  • Participate in the Architecture Review Board involving key stakeholders to ensure collaboration and company alignment behind the designs being produced.
  • Evaluate tradeoffs between performance, power, cooling, serviceability, and cost throughout the procurement process.
  • In tandem with potential suppliers, drive the creation of detailed low-level designs, including (but not limited to):
  • Rack elevation diagrams and layouts
  • Data center floor plans and spatial planning
  • Power distribution and cooling architecture and related detailed specifications
  • Detailed Bill of Materials (BoM)
  • Port mapping documents.
  • Drive thorough technical evaluations and response accuracy from vendors during the RFx processes, ensuring designs are aligned with vendor capabilities and long-lead item constraints.
  • Play a hands-on and pro-active role in the manufacturing, burn-in, cabling, logical configuration, benchmarking, and logical implementation of new deployments to turn designs into production-grade systems.
  • Drive acceptance criteria with quality, reliability, safety, and performance goals in mind.
  • Work with the Software Engineering and Solutions Engineering teams to ensure the infrastructure supports AI workload requirements.
  • Engage with project management to define milestones, risks, resourcing, and deliverables associated with the delivery.
  • Produce accurate architecture diagrams, configuration documentation, runbooks, and operational guidance to facilitate the handover of the new deployments to the Infrastructure Operations team.
  • Establish delivery best practices and continuously improve the designs, processes, and documentation through the participation of "lessons learned" workshops.

Requirements

  • BSc in Computer Science, Electrical/Computer Engineering, Physics, Mathematics, or other related Engineering fields.
  • 5+ years of solution architecture experience, demonstrating motivation and skills to drive technical design and delivery processes.
  • Deep expertise in datacenter engineering (mechanical, electrical and plumbing), GPU systems, high performance networking (like InfiniBand), including a proven understanding of network topologies and storage architecture.
  • Proficiency in system-level aspects, encompassing Operating Systems, Linux kernel drivers, GPUs, NICs, and infrastructure software solutions.
  • Demonstrated experience producing detailed infrastructure designs (including network topologies, rack layouts, BoMs, power/cooling planning…)
  • Deep understanding in datacenter fit-out, and power/cooling constraints
  • Excellent interpersonal and communication skills, with a track record interfacing with various types of stakeholders (engineering/operations teams, vendors, etc.) and writing clear deliverables.
  • Comfortable working in fast-moving, high-complexity technical environments.

Nice to have

  • Prior work experience in HPC, Telco, or hyperscale supercomputing environments designing, delivering, and/or operating large scale HPC systems.
  • Work or research experience in networking fundamentals, TCP/IP stack, and data center designs.
  • Familiarity with monitoring/telemetry systems and observability for infrastructure health.
  • Demonstrated expertise in cloud orchestration software and job schedulers, including platforms like Kubernetes, Docker Swarm, and HPC-specific schedulers such as Slurm.
  • Knowledge of DevOps/MLOps technologies such as Docker/containers, Kubernetes, datacenter compute/network/storage deployments.
  • Hands-on experience with NVIDIA systems/SDKs (e.g., CUDA), NVIDIA Networking technologies (e.g., DPU, RoCE, InfiniBand), ARM CPU solutions, coupled with proficiency in C/C++ programming, parallel programming, and GPU development.

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do.

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person.

Our Data Environment

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
  • Believe in clean coding, simple solutions, automated testing and continuous deployment.
  • Like to take ownership of a feature from the original idea through to live.
  • Think (like us) that a small number of empowered developers is the right way to deliver software.
