Senior Data & Integration Architect in London

As a world leading provider of integrated solutions for the alternative investment industry, Alter Domus is proud to be home to 90% of the top 30 asset managers in the private markets, and more than 6,000 professionals across 24 jurisdictions. With a deep understanding of what it takes to succeed in alternatives, we believe in being different - in what we do, in how we work and most importantly in how we enable and develop our people.

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

Required 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

Profile

You are a senior architect who:

• Thinks 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

Outcome

With this role in place:

• 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
• The service transition becomes predictable, controllable, and future-proof

This role is central to making the transformation operationally sound and sustainable.
