We are establishing a data‑driven service delivery model in which operational processes will progressively move from the client’s landscape into ours.

For a period of time, both environments will interact as part of a single service chain.

This requires clear ownership of data, well‑defined integration patterns, and controlled transitions between systems.

The Senior Data & Integration Architect provides the architectural leadership to design these flows, define boundaries, and ensure that the service can operate reliably throughout this evolution.

Role Purpose

The Senior Data & Integration Architect is responsible for defining and governing the data and integration architecture that underpins this transformation. The role ensures that:

  • Data ownership and system boundaries are clear and enforceable
  • Integration patterns support coexistence and progressive transition
  • Architectural decisions translate into executable, delivery‑ready designs
  • Service continuity is preserved as the landscape evolves

This role provides the technical backbone of the transition and enables the organization to move with control and confidence.

Key Responsibilities

  • Define the target data and integration architecture for the service landscape
  • Design transition patterns that allow two environments to operate together
  • Establish data ownership models, system boundaries, and integration contracts
  • Support wave and delivery planning with executable architectural designs
  • Identify and mitigate risks related to data flows and dependencies
  • Define standards and guardrails for integrations and transitional states
  • Provide clear architectural options and trade‑offs for complex decisions
  • Work closely with domain architects, PMs, technical leads, and platform teams
  • Ensure architectural consistency across domains and delivery streams
  • Data boundaries between landscapes are explicit and controlled
  • Integration patterns are consistent and scalable
  • Delivery waves are architecturally sound and executable
  • Transitional states are designed rather than improvised

What We Offer

  • Support for professional accreditations such as ACCA and study leave
  • Flexible arrangements, generous holidays, plus an additional day off for your birthday!
  • Continuous mentoring along your career progression
  • Active sports, events and social committees across our offices
  • 24/7 support available from our Employee Assistance Program
  • The opportunity to invest in our growth and success through our Employee Share Plan
  • Plus additional local benefits depending on your location
  • Equity in every sense of the word: We are in the business of equity, in every sense of the word.

We celebrate our differences, and understand that our success relies on diverse perspectives and experiences, working towards shared goals and a common purpose.

We take pride in creating a workplace where all our people are empowered to be truly invested in the alternative and bring their whole self to work.

Qualifications and Experience

  • Senior‑level experience in solution architecture with strong focus on:
  • Data architecture
  • System integration and API design
  • Complex application landscapes

• Experience in large‑scale transformation programs, such as

  • Service transitions
  • Carve‑outs or M&A environments
  • Multi‑platform coexistence scenarios

• Solid understanding of

  • Data ownership and governance
  • Event‑driven and API‑based architectures
  • Transitional and hybrid architectures
  • Ability to operate in in‑flight programs with evolving scope and constraints
  • Think in systems rather than isolated components
  • Can reason across business, data, and technology
  • Is comfortable in complex, evolving environments
  • Balances architectural rigor with delivery pragmatism
  • Engages credibly with engineers, PMs, and leadership
  • Turns complex transitions into structured, executable designs
