The Opportunity

We are seeking a seasoned Technical Architect to lead the architecture of complex investment systems at a mission-driven financial institution. This key role involves owning the front-to-back architectural integrity of the investment platform, ensuring seamless integration across Portfolio Management (PMS), Investment Book of Record (IBOR), and Accounting Book of Record (ABOR). Responsibilities include defining the technical roadmap, influencing strategy, and ensuring scalable, resilient systems for long-term growth.

Lead system transitions, integrations, and modernization.

Ensure architectural alignment across private equity and debt lifecycles.

Service Design Leadership

Lead Service Design workshops; translate requirements into scalable technical blueprints.
Champion long-term architectural integrity.

Architectural Output & Governance

Produce high-quality architectural artefacts (HLDs, LLDs, integration patterns) aligned with enterprise standards.
Ensure traceability from business requirements to implementation.

Data & Reporting Excellence

Design and optimize back-end data models for regulatory, financial, and impact reporting.
Ensure consistent, accurate IBOR and ABOR reporting.

Expertise:

Deep domain knowledge of investment management lifecycles (PE/PD preferred).
Expertise in capital calls, waterfall distributions, and valuations.

Systems:

Proven experience with PMS, IBOR, and ABOR systems.
Track record leading system integrations/platform transitions.

Architecture:

Ability to apply Service Design to complex finance.
Experience delivering enterprise-wide production-ready architectural outputs.

Data:

Strong experience in back-end data modelling for complex financial/regulatory reporting.

The Bridge

Ability to translate complex investment terminology into actionable technical requirements — and articulate technical constraints clearly to business stakeholders.

Why Join?

You will play a critical role in strengthening the technology foundation that supports large-scale investment activity and economic impact. This is an opportunity to build a “gold standard” investment architecture within a high-stakes, purpose-led environment.

If you are passionate about investment technology, architectural excellence, and building resilient financial systems that enable long-term growth — we would love to hear from you.
