Placing a Head of Digital Banking Architecture for a Tier-1 Bank, Case Study
As we know, many Tier-1 banks struggle to modernise, due to them being trapped by rigid legacy systems and a lack of niche technical talent.
As a result, finding leaders who truly understand both high-stakes compliance and agile cloud technology is notoriously difficult.
That is why for this Tier-1 bank, Mark Loucas stepped in with a global search, mapping talent across our pool of people in London, Singapore, and Berlin.
By leveraging our specialist network, we then bypassed the usual talent pools to find a leader with the perfect combination of corporate maturity and startup agility to help our client fill their space.
Let’s find out how we accomplished this.

Project Overview
1. Sector – Tier-1 International Retail Banking
2. The Role – Head of Digital Banking Architecture
3. Location – London (Global Search)
4. Service – Executive Search & Talent Mapping
The Context
Our client, a Tier-1 International Retail Bank with a legacy spanning decades, reached a key inflexion point.
For them to remain competitive against a new wave of agile “Challenger Banks” and changing consumer expectations, they embarked on a multi-year digital transformation journey.
Central to this, though, was the migration of their entire core banking infrastructure – moving from siloed, on-premise legacy systems to a scalable, cloud-native ecosystem that they needed a leader to help them through.
The Challenge, in finding their "Unicorn" Profile
The search for a Head of Digital Banking Architecture presented a unique challenge here.
The ideal candidate needed a rare “bilingual” skill set in a few areas, such as:
Technical Modernity
Here, they needed deep, hands-on experience with AWS / Azure cloud architecture, microservices, and an API-first banking mindset.
Institutional Knowledge
They also needed to have a good understanding of the rigorous compliance, risk frameworks, and “Red tape” inherent in a Tier-1 regulated environment at the same time.
Due to this, in a hyper-competitive candidate market, individuals who possess the agility of a Fintech startup but the gravitas to navigate a global corporate boardroom are actually exceptionally rare.
Here, traditional recruitment methods had failed to identify a candidate who could bridge this cultural and technical divide well enough.
Our Fintech Recruitment Approach
However, here at Mark Loucas, our Fintech recruiters instead deployed a more targeted, multi-territory executive search strategy to help to get around a skill set lax in their prior search regions.
For instance, here we moved beyond job boards, focusing instead on Passive Talent Mapping across three global financial hubs, including:
1. London
2. Singapore
3. Berlin
Competitor Mapping
We then identified specific “Challenger” institutions that had recently successfully scaled their operations.
From this, we then targeted the architects behind these moves directly – individuals who had already solved the problems our client was just beginning to face – to see if their work balance still suited them.
Cultural Assessment
We then did not just vet these people for technical prowess.
For example, instead, we interviewed for “corporate maturity.”
As here we needed to make sure that the candidate would not be frustrated by the slower pace of a Tier-1 bank, but would instead act as a patient, persuasive catalyst for change for them instead.
Global Reach
Then, by leveraging our international network, we were able to present a diverse range of candidates with varying perspectives on global banking regulations (including requirements the client was looking for, such as GDPR, PSD2, and MAS).
The Result
Despite the complexity of the brief, our deep vertical specialisation allowed us to move with pace.
Within just four weeks, our consultants here at Mark Loucas presented a shortlist of three highly qualified, pre-vetted candidates, all of whom met the “unicorn” criteria the client was looking for.
The Hire
The successful candidate was a former CTO from a prominent European Neobank who had previously spent their early career in traditional finance, and who ticked all the boxes the client was looking for.
The Impact
Within the first 12 months, the new Head of Architecture successfully steered the first phase of the cloud migration.
This architectural shift allowed the bank to then reduce its “Time-to-Market” for new digital products by 30%, which in turn helped to transform the bank from a legacy follower into one of the digital leaders in the region as a result.
