Qualifications

  • Principal Software Architect - UK Security Clearance eligibility required.
  • About You
  • You are an architecturally minded senior engineer: someone who thinks in domains, systems, and trade-offs, but who has never stopped coding.
  • You believe that good architecture starts with a deep understanding of the business domain, and you're energised by shaping the why and what of a solution as much as the how.
  • You're comfortable challenging established thinking with customers in a consulting environment, earning influence through credibility, clarity, and delivery.
  • You'll bring:
  • Experience leading collaborative domain discovery with business stakeholders, using techniques such as Event Storming, domain storytelling, or similar.
  • Strong architectural judgement, with a track record of owning and driving solution design on complex systems, not just contributing to it.
  • The ability to understand a customer's business architecture, connect it to technical decisions, and constructively challenge it when it doesn't serve the outcome.
  • Confidence communicating and defending architectural decisions to senior stakeholders, and documenting them clearly (e.g.
  • ADRs, C4 or similar).
  • Strong hands-on full-stack development

Responsibilities

  • Own the architecture and solution design of modern, scalable software systems across customer engagements.
  • Lead domain discovery and modelling with customers, establishing bounded contexts, a ubiquitous language, and a shared understanding between business and engineering.
  • Shape and challenge business and technical architecture: service boundaries, domain models, dependencies, and integration strategy across complex systems.
  • Ensure the domain model is reflected in the software itself, keeping code, architecture, and business understanding aligned as systems evolve.
  • Act as a trusted architectural advisor to customers, guiding decision-making, articulating trade-offs, and influencing direction at a senior level.
  • Work hands-on across the stack, particularly on React-based applications.
  • Architecture at App*** is done in the code, not just on the whiteboard.
  • Establish and document architectural decisions, patterns, and standards that outlive individual engagements.
  • Drive improvements in development processes, testing strategy, and delivery cadence.
  • Support teams in reducing technical debt and improving long-term maintainability and evolvability.
  • Collaborate with platform and cloud engineers to deliver cohesive end-to-end solutions.
  • Mentor engineers and grow DDD and architectural capability within App***'s engineering practice.
