A globally recognised financial markets infrastructure firm is hiring a Senior Platform Architect to play a pivotal role in transforming a high-profile, business-critical platform.
This is a true transformation piece - moving from a complex legacy estate toward a modern, cloud-native, scalable platform that directly underpins core business operations.
The Opportunity
This role sits at the intersection of architecture, engineering, and business strategy.
You'll take ownership of architectural direction across a globally distributed engineering function, working closely with senior stakeholders to shape how the platform evolves - both technically and commercially.
This isn't governance from a distance - you'll be close to engineering, influencing design decisions and driving modern best practices across the stack.
What You'll Be Doing
- Define and own the platform architecture strategy across multiple teams and regions
- Drive the transition from legacy systems to cloud-native architecture
- Ensure systems are scalable, resilient, and built for long-term growth
- Partner closely with engineers to embed modern development practices
- Engage senior stakeholders across tech and business, translating architecture into real commercial outcomes
- Act as a technical leader and influencer, shaping how the platform is built and evolves
Technology Environment
- Backend: TypeScript (Node.js)
- Frontend: JavaScript / React
- Cloud: AWS (containers, serverless, wider ecosystem)
- Architecture: Distributed systems, microservices, cloud-native design
What They're Looking For
- Proven experience as a Platform / Solution Architect in modern cloud environments
- Strong background building scalable, distributed systems
- Deep understanding of AWS and cloud-native architecture patterns
- Ability to operate at a senior stakeholder level (both technical & business)
- Strong communication and influencing skills
- A modern engineering mindset - comfortable challenging legacy approaches
