Data Engineer (with Data Analytics Background)

Location: City of London

Employment Type: Full-time

Salary: £90,000-£100,000

Sector: Fintech

We're looking for a well-rounded, communicative Data Engineer with a strong background in data analytics and experience within the Fintech sector. This role is ideal for someone who began their career as a Data Analyst and has since transitioned into a more engineering-focused position, someone who enjoys understanding the business context just as much as building the data solutions behind it.

You'll work extensively with Python, Snowflake, SQL, and dbt to design, build, and maintain scalable, high-quality data pipelines and models that support decision-making across the business. This is a hands-on, collaborative role, suited to someone who's confident communicating with data, product, and engineering teams, not a "heads-down coder" type.

Top 4 Core Skills

Python - workflow automation, data processing, and ETL/ELT development.
Snowflake - scalable data architecture, performance optimisation, and governance.
SQL - expert-level query writing and optimisation for analytics and transformations.
dbt (Data Build Tool) - modular data modelling, testing, documentation, and version control.

Key Responsibilities

Design, build, and maintain dbt models and SQL transformations to support analytical and operational use cases.
Develop and maintain Python workflows for data ingestion, transformation, and automation.
Engineer scalable, performant Snowflake pipelines and data models aligned with business and product needs.
Partner closely with analysts, product managers, and engineers to translate complex business requirements into data-driven solutions.
Write production-grade SQL and ensure data quality through testing, documentation, and version control.
Promote best practices around data reliability, observability, and maintainability.
(Optional but valued) Contribute to Infrastructure as Code and CI/CD pipelines (e.g., Terraform, GitHub Actions).

Skills & Experience

5+ years of experience in data-focused roles, ideally progressing from Data Analyst to Data Engineer.
Proven Fintech or Payments industry experience - strong understanding of the data challenges and regulatory context within the sector.
Deep proficiency in Python, Snowflake, SQL, and dbt.
Excellent communication and collaboration skills, with the ability to work effectively across data, product, and business teams.
Solid grasp of modern data modelling techniques (star/snowflake schemas, data contracts, documentation).
Experience working in cloud-based environments; familiarity with Terraform or similar IaC tools is a plus.
Proactive, delivery-focused, and able to contribute quickly in a fast-moving environment.

Nice to Have

Experience with Power BI or other data visualisation tools.
Familiarity with orchestration tools such as Airflow, Prefect, or Dagster.
Understanding of CI/CD practices in data and analytics engineering.
Knowledge of data governance, observability, and security best practices in cloud environments

How Many Data Science Tools Do You Need to Know to Get a Data Science Job?

If you’re trying to break into data science — or progress your career — it can feel like you are drowning in names: Python, R, TensorFlow, PyTorch, SQL, Spark, AWS, Scikit-learn, Jupyter, Tableau, Power BI…the list just keeps going. With every job advert listing a different combination of tools, many applicants fall into a trap: they try to learn everything. The result? Long tool lists that sound impressive — but little depth to back them up. Here’s the straight-talk version most hiring managers won’t explicitly tell you: 👉 You don’t need to know every data science tool to get hired. 👉 You need to know the right ones — deeply — and know how to use them to solve real problems. Tools matter, but only in service of outcomes. So how many data science tools do you actually need to know to get a job? For most job seekers, the answer is not “27” — it’s more like 8–12, thoughtfully chosen and well understood. This guide explains what employers really value, which tools are core, which are role-specific, and how to focus your toolbox so your CV and interviews shine.

What Hiring Managers Look for First in Data Science Job Applications (UK Guide)

If you’re applying for data science roles in the UK, it’s crucial to understand what hiring managers focus on before they dive into your full CV. In competitive markets, recruiters and hiring managers often make their first decisions in the first 10–20 seconds of scanning an application — and in data science, there are specific signals they look for first. Data science isn’t just about coding or statistics — it’s about producing insights, shipping models, collaborating with teams, and solving real business problems. This guide helps you understand exactly what hiring managers look for first in data science applications — and how to structure your CV, portfolio and cover letter so you leap to the top of the shortlist.

The Skills Gap in Data Science Jobs: What Universities Aren’t Teaching

Data science has become one of the most visible and sought-after careers in the UK technology market. From financial services and retail to healthcare, media, government and sport, organisations increasingly rely on data scientists to extract insight, guide decisions and build predictive models. Universities have responded quickly. Degrees in data science, analytics and artificial intelligence have expanded rapidly, and many computer science courses now include data-focused pathways. And yet, despite the volume of graduates entering the market, employers across the UK consistently report the same problem: Many data science candidates are not job-ready. Vacancies remain open. Hiring processes drag on. Candidates with impressive academic backgrounds fail interviews or struggle once hired. The issue is not intelligence or effort. It is a persistent skills gap between university education and real-world data science roles. This article explores that gap in depth: what universities teach well, what they often miss, why the gap exists, what employers actually want, and how jobseekers can bridge the divide to build successful careers in data science.
