It has a leading franchise in many major metals, energy and agricultural products, with access to 60 exchanges. The group provides access to the world’s major commodity markets, covering a broad range of clients that include some of the largest commodity producers, consumers and traders, banks, hedge funds and asset managers. With more than 40 offices worldwide, the group has over 2,300 employees across Europe, Asia and the Americas. Marex operates across global financial markets with significant presence both on and off exchange. The firm provides clients with market access, execution, clearing, risk management, data and analytics. The Technology division delivers scalable and secure systems across the business. Teams work in agile streams aligned to business areas, supported by architecture, infrastructure, security and design. The Design function spans Product Design, Design Engineering, Brand and Digital. The team operates on an infrastructure‑first model — building the platform that lets the wider organisation produce quality output at scale.

Role Summary

The Design Systems Architect is responsible for defining what the Marex Design System is — its architecture, token structure, component taxonomy, and the way it is built so that both humans and AI can consume it correctly. Most design systems are built for designers and developers. The Marex Design System needs to work for a third consumer: AI. This role owns the structural and semantic foundation that makes that possible, ensuring the system can be reasoned about, assembled, and extended by both people and machines. The role requires deep design systems expertise, genuine technical fluency, and the ability to work credibly across design and engineering teams. Figma is the current primary tool, but the system must be architected so it is not dependent on any single tool — tokens, structure, and component logic should exist independently, with Figma as the human‑readable layer for now. The Design Systems Architect works in close collaboration with Design Engineering, who own the engineering artefacts of MDS. The boundary is clear: this role decides what the system is and how it is structured; Design Engineering decides how it is built and shipped.

Responsibilities

• Own the architecture of the Marex Design System — token structure, component taxonomy, naming conventions, and modularity model — designed to be consumed by humans, engineers, and AI tooling equally.
• Design the token system: semantic layers, theming model, light/dark pairing, typography scales, grid and spacing — structured so they exist independently of any single tool.
• Define component anatomy: what each component is, what variants it has, what props it exposes, and how it is documented — with AI consumption in mind from the start.
• Architect the Figma system: library structure, variable‑to‑token mapping, component construction — modular, consistent, and machine‑legible.
• Define the AI consumption model for the system: prompt guardrails, component constraints, and the rules that allow AI to generate on‑system output reliably.
• Own design system governance in collaboration with Design Engineering and Product Design: contribution standards, component creation criteria, and how the system evolves without fragmenting.
• Maintain the documentation layer that makes the system genuinely usable — not just a component library, but a system people understand how to extend.
• Ensure AI‑generated output meets system standards — build constraints rather than open‑ended flexibility.
• Work with Design Engineering on code connect, token sync, and the Figma‑to‑production pipeline — you own the design architecture side of that boundary.

All Staff Duties

• Ensure compliance with the company’s regulatory requirements under the FCA.
• Adhere to the operational risk framework for your role ensuring that all regulatory or company determined parameters are complied with.
• Role model for demonstrating highest level standards of integrity and conduct and reflecting Company Values.
• At all times comply with the FCA’s Code of Conduct.
• Ensure that you are fully aware of and adhere to internal policies that relate to you, your role or any other activities for which you have any level of responsibility.
• Report any breaches of policy to Compliance and/or your supervisor as required.
• Escalate risk events immediately.
• Provide input to risk management processes, as required.

Competencies, Skills, Experience & Qualifications

• Deep experience owning or significantly shaping a design system in a complex product environment — you have made the hard decisions about token structure, component scope, and governance.
• Strong Figma proficiency at a systems level — variables, component architecture, library structure, auto‑layout — not just the ability to use it but the ability to architect it.
• A genuine understanding of how AI consumes design systems — you have thought seriously about what modular, machine‑legible component structure means in practice.
• Sufficient technical fluency to work credibly with engineers on token pipelines, code connect, and the design‑to‑code boundary — you do not need to write the production code but you need to understand what you are handing to the people who do.
• Design sensibility that goes beyond systems thinking — you make good visual and UX judgement calls, and the system you build reflects that, not just technical correctness.
• The instinct to build constraints rather than infinite flexibility — you understand that a system that can do anything produces inconsistency, and a well‑governed system produces quality.
• Comfortable with ambiguity at the frontier — AI‑first design systems are not a solved problem, you are figuring this out as you go, and that energises rather than unsettles you.
• Experience in financial services, regulated industries, or complex B2B enterprise environments is a real advantage.
• Solid understanding of financial markets or financial services environments, or a demonstrated ability to quickly absorb complex financial concepts.
