We tackle the most complex problems in quantitative finance, by bringing scientific clarity to financial complexity. From our London HQ, we unite world-class researchers and engineers in an environment that values deep exploration and methodical execution - because the best ideas take time to evolve. Together we're building a world-class platform to amplify our teams' most powerful ideas. You'll shape the platforms and tools that drive high-impact research - designing systems that scale, accelerate discovery and support innovation across the firm.
The role
We are seeking an experienced Infrastructure Architect to join our Platform and Solution Architecture team. In this role, you'll own the infrastructure roadmap and help define architectural standards across our hybrid environment of private and public cloud platforms. Working closely with other architects in the team, you'll focus primarily on private cloud and on-premises infrastructure while defining integration strategies with our public cloud platforms. Your expertise will guide critical decisions on workload placement, technology selection and infrastructure governance, directly influencing how our engineering teams build and deploy systems at scale. This role is critical to our technology strategy. You'll be shaping infrastructure that processes billions of data points daily, supports latency-sensitive workloads and must scale seamlessly. Your architectural decisions will impact our competitive advantage and operational efficiency for years to come.
Key responsibilities of the role include:
- Owning and developing the on-premises infrastructure roadmap, ensuring alignment with business objectives and collaborating with Platform and Solution architects to deliver integrated strategies
- Establishing infrastructure principles, standards and patterns that drive consistency, interoperability and quality across our environment
- Evaluating and selecting infrastructure technologies, assessing both traditional vendors and cloud providers to make informed recommendations
- Acting as the technical authority for on-premises architecture, providing leadership on key decisions and serving as an escalation point for engineering teams
- Championing architectural best practices across the organisation, ensuring infrastructure designs support broader technology initiatives
- Partnering with engineering teams to translate architectural vision into delivered capabilities, using influence and collaboration to drive adoption
- Ensuring infrastructure governance and compliance, proactively managing risk while maintaining pragmatic balance between security and business agility
Who are we looking for?
The ideal candidate will have the following skills and experience:
- Extensive experience in infrastructure architecture with a strong focus on private cloud and on-premises environments
- Deep expertise in virtualization and container platforms (VMware, OpenStack, KVM, Kubernetes) and in Infrastructure-as-Code practices
- Comprehensive networking knowledge, spanning physical infrastructure (switching, routing), network virtualization (SDN, VXLAN), and container networking (overlay networks, CNIs)
- Hands-on experience with public cloud platforms (AWS preferred) and hybrid connectivity patterns
- Proven ability to design and deliver infrastructure roadmaps for complex organizations, translating detailed technical design into actionable, strategic plans
- Strong leadership and influence skills, driving consensus across diverse stakeholder groups and influencing without authority
- Excellent technical communication, making complex infrastructure decisions clear and accessible to both technical and executive audiences
The following skills and experience are desirable:
- Experience in performance-critical environments with low-latency and data gravity requirements
- Experience with forward proxy and perimeter security solutions, such as explicit / transparent proxy
- Hands-on knowledge of Kubernetes and container orchestration platforms
- Infrastructure automation and observability platforms experience
- Emerging technology awareness, keeping an eye on the latest in AI/ML infrastructure and edge computing
- Industry certifications, such as AWS Solutions Architect, VMware VCP or similar
We value architects who combine strategic thinking with hands-on expertise and understand that robust on-premises infrastructure remains as critical as cloud innovation. You'll thrive here if you make decisions based on data rather than trends, and can articulate trade-offs clearly to help others make informed choices. Join us to tackle complex infrastructure challenges at scale.
Why should you apply?
- Highly competitive compensation plus annual discretionary bonus
- Lunch provided (via Just Eat for Business) and dedicated barista bar
- 30 days' annual leave
- 9% company pension contributions
- Informal dress code and excellent work/life balance
- Comprehensive healthcare and life assurance
- Cycle-to-work scheme
- Monthly company events
