Step up and take the technical helm of one of the UK’s most iconic digital estates. Currently looking for a Senior Solutions Architect (Digital Platforms – Web / Mobile) to spearhead the engineering roadmap for a high-concurrency national platform. This isn’t just about drawing boxes; it’s about building the resilient, secure, and hyper-scalable foundations that power millions of weekly interactions.

Role Overview

  • Location: Hybrid (North London)
  • Package: £95,000-£110,000 + Performance Bonus + Strong Benefits

The Mission

  • Architectural Sovereignty: Define the technical blueprints for web and mobile ecosystems, ensuring every component is optimised for performance, security, and sub-second latency.
  • Engineering Leadership: Act as the bridge between high-level strategy and execution, working deeply with in-house and nearshore squads to ensure code-level adherence to architectural standards.
  • Legacy Modernisation: Lead the aggressive transition from monolithic debt to decoupled, cloud-native microservices and server-less architectures.
  • Technical Governance: Own the full-stack design lifecycle, producing rigorous HLDs and LLDs while ensuring seamless integration across complex third-party and internal APIs.
  • Strategic Alignment: Partner with Enterprise Architects to ensure local technical decisions reinforce global scalability and long-term infrastructure goals.

Your Technical Stack & DNA

  • Architecture Tenure: 8+ years as a Technical/Solution Architect, specifically within high-traffic, B2C digital environments.
  • Cloud & Modern Web: Deep-rooted expertise in AWS/Azure ecosystems and modern frontend/backend frameworks (e.g., React, Node.js, Swift/Kotlin).
  • Systems Design: Proven track record in building distributed systems, event-driven architectures, and robust integration patterns.
  • DevOps Mastery: You don’t just know CI/CD; you understand how to architect for automated testing, containerisation (Kubernetes/Docker), and Infrastructure as Code (Terraform/Bicep).
  • Framework Proficiency: Expert application of TOGAF, UML, or ArchiMate within Agile/SAFe delivery cadences.
  • Sector Experience: Experience navigating the complexities of highly regulated sectors (e.g., Finance, Gaming, or Utilities).

Why This Move?

  • Impact: Own the technical evolution of a top-tier UK website and a flagship mobile app.
  • Innovation: Lead a “once-in-a-career” digital overhaul backed by massive global investment. xwzovoh
  • Culture: A hybrid, inclusive environment where technical excellence is celebrated and rewarded.
  • Purpose: Build systems that don’t just generate revenue, but support significant social causes on a national scale
