Solutions Architect – Asset Servicing

Permanent | Hybrid - 2x a week in London | Financial Services

Bestman Solutions is supporting a leading financial market infrastructure organisation undergoing significant technology modernisation across its post-trade platforms.

We are looking for an experienced Solution Architect to join a growing architecture function, with a particular focus on Asset Servicing.

This role will be responsible for defining target architecture and designing end-to-end solutions across complex, business-critical platforms. You will sit between enterprise architecture and engineering, translating strategic direction into pragmatic, technically deliverable solutions.

The ideal candidate will combine strong solution architecture experience with a good understanding of modern software engineering and, importantly, Asset Servicing or wider post-trade processes.

Key Responsibilities

• Define end-to-end solution architectures across Asset Servicing and wider post-trade technology initiatives
• Ensure solutions meet functional, non-functional, security, resilience, and architectural requirements
• Translate enterprise and domain architecture principles into practical technology solutions
• Work closely with Domain Architects, Product Owners, Engineering teams, and other technology stakeholders
• Contribute to target architectures and technology roadmaps for the Asset Servicing domain
• Design solutions using event-driven, service-based, API, and microservices architectures
• Provide architectural guidance throughout the delivery lifecycle, from initial design through to implementation
• Identify technical dependencies, risks, and architectural trade-offs across complex programmes
• Develop reusable architecture patterns and technology building blocks
• Support the continued development of Solution Architecture and Software Engineering practices
• Provide pragmatic recommendations while maintaining alignment with wider enterprise standards

Required Experience

• Significant experience as a Solution Architect, ideally within large-scale transformation programmes
• Strong understanding of Asset Servicing, securities, post-trade, or capital markets technology
• Experience designing complex, end-to-end technology solutions within enterprise environments
• Strong knowledge of event-driven architecture, microservices, service-based architecture, and REST APIs
• Technical experience across environments such as:
• Java and Linux
• OpenShift / containerised platforms
• Azure Cloud
• Mainframe or Tandem environments
• Good understanding of integration patterns and data technologies
• Experience working within Agile and DevOps environments, including CI/CD
• Ability to move comfortably between high-level architecture and detailed technical implementation
• Strong analytical and problem-solving skills across complex systems and technology estates
• Ability to challenge constructively and communicate architectural recommendations to both engineering teams and senior stakeholders

Desirable Experience

• Strong knowledge of Asset Servicing processes, such as corporate actions, income, custody, securities processing, or related areas
• Experience within post-trade market infrastructure, securities services, banking, or capital markets
• Understanding of the regulatory environment surrounding securities and post-trade services
• Experience with SAFe or other scaled Agile delivery models
• Knowledge of Enterprise Architecture frameworks such as TOGAF or Open Agile Architecture
• Experience with JavaScript front-end frameworks such as Angular

The Opportunity

This is an opportunity to influence the architecture of major post-trade platforms at a time of significant technology transformation.

You will have the scope to shape target architecture, work closely with engineering teams on how solutions are actually delivered, and contribute to the evolution of architecture practices across a complex financial technology environment.

Interviews will commence shortly.
