Solutions Architect (Payments / Fintech Transformation)

Location: London (Hybrid)

Contract: 18‑month Fixed Term Contract

The Opportunity

We are supporting a newly formed, high‑growth payments business backed by significant strategic investment and operating with a fintech mindset. This is a rare opportunity to join during a foundational phase, helping to design and deliver a clean, modern SaaS‑first enterprise technology landscape as part of a large‑scale transformation.

The organisation is creating a standalone payments acquiring business, combining the stability of an established payments operation with the pace, autonomy, and innovation culture of a fintech. This role is ideal for someone who thrives in fast‑moving, flat organisations and enjoys having genuine influence over architectural decisions.

The Role

We are seeking an experienced Solutions Architect to lead the design and integration of a new enterprise applications estate, replacing a complex legacy environment with a streamlined SaaS architecture across Finance, Risk, HR and corporate functions.

The focus of the role is business application architecture and integration, including connectivity to identity management, data platforms, and shared enterprise services. Infrastructure‑level design (e.g. cloud hosting, data warehouse engineering) will be handled by specialist peer teams.

This is an 18‑month fixed‑term role, created to drive delivery.

Key Responsibilities

Design and deliver end‑to‑end solutions that address complex business problems while balancing technology risk and delivery pace.

Create SaaS‑centric architectures that evolve over time and align with modern engineering and automated delivery practices.

Lead targeted design activities that maximise the value of cloud capabilities such as elasticity, containerisation and serverless.

Produce secure, resilient designs aligned to best‑practice security principles and operational expectations.

Ensure solutions balance risk, control, cost and business value appropriately.

Drive adoption of standardised enterprise solutions, influencing their evolution where gaps exist.

Support operational teams with fault‑finding and performance investigations, using available tooling.

Assess architectural impacts across risk, capacity and cost, including change and ongoing run costs.

Produce architecture artefacts required for governance across architecture, security, privacy and records management forums. About You

You will bring senior‑level architectural experience and be confident operating with autonomy in a transformation environment.

Essential Experience

Proven experience designing SaaS‑focused enterprise architectures spanning multiple business applications.

Background in one or more of the following domains: Finance, Risk, HR, or corporate functions (e.g. Compliance, Legal, Procurement).

Experience onboarding and integrating SaaS vendors within financial services or fintech environments.Highly Valued

Experience working in fintechs or smaller, scale‑appropriate organisations.

A highly proactive, self‑sufficient mindset, comfortable making decisions and driving outcomes.Working Model

Where to Advertise Data Science Jobs in the UK (2026 Guide)

Where to advertise data science jobs UK in 2026: the specialist boards, communities and channels that actually reach senior and lead data science talent. Data science spans a broad and often misunderstood spectrum — from statistical modelling and experimental design through to machine learning engineering, product analytics and AI research. The strongest candidates identify firmly with specific subdisciplines and are frustrated by adverts that conflate data scientist with data analyst, business intelligence developer or machine learning engineer. General job boards produce high application volumes for data roles but consistently fail to match specialist data science profiles with the right opportunities. This guide, published by DataScienceJobs.co.uk, covers where to advertise data science roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Data Science Jobs UK 2026: What to Expect Over the Next 3 Years

Data Science Jobs UK 2026: roles, salaries and the trends shaping UK data science hiring over the next three years — from MLE crossover to GenAI workflows. Data science has spent the past decade being described as the sexiest job of the twenty-first century. By 2026, the reality is both more nuanced and more interesting than that label ever suggested. The discipline has matured, fragmented, deepened, and in some respects reinvented itself — and the jobs market has changed with it in ways that create genuine opportunity for those who understand what employers actually want, and genuine difficulty for those still operating on assumptions formed five years ago. The data science jobs market of 2026 is not simply a larger version of what it was three years ago. The generalist data scientist — equally comfortable wrangling data, building models, and presenting insights to the board — is giving way to a more specialised landscape where employers know exactly what problem they are trying to solve and are looking for candidates with the specific depth to solve it. Machine learning engineering, causal inference, experimentation, AI product development, and domain-specific applied science have all emerged as distinct career tracks within what was previously a single, loosely defined profession. At the same time, the arrival of large language models and the broader AI capability wave has both threatened and created data science roles in equal measure. Some of the work that junior data scientists spent their early careers doing — data cleaning, exploratory analysis, basic model building — is being partially automated by AI tooling. But the demand for practitioners who can evaluate AI systems rigorously, apply statistical thinking to complex business problems, and build the data foundations on which AI depends has grown considerably. The candidates who will thrive over the next three years are those who understand where the discipline is heading — which specialisms are attracting the most investment, which technologies are reshaping what data scientists are expected to build and know, and how to position a data science career that will remain valuable as the field continues to evolve around them. This article breaks down what the UK data science jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career ahead of the curve.
