AWS Data Engineer | 6m Contract | London, Hybrid - Outside IR35 

Daily Rate: £570 per day (Outside) Team: Data Engineering - Application Development

Overview:

Opus have partnered with a London Financial Services company who're seeking a Senior AWS Data Engineer with a background in Application Development to support in architecting and delivering a new PostgreSQL‑driven data platform which will be used to support core functions across investment reporting, risk analysis, regulatory output, and performance measurement.

This is a high‑impact greenfield build. You’ll take full ownership of the platform’s design and lead the transition away from Databricks and Excel-centric processes—shaping critical infrastructure that underpins the organisation’s investment operations.

What You’ll Work On

You’ll be responsible for designing and developing a scalable, secure PostgreSQL environment capable of supporting:

Portfolio valuation and holdings data

Performance and attribution reporting

Risk and analytics outputs

Regulatory and trustee disclosures

Data governance and operational controls

You’ll also oversee the migration of structured datasets from Databricks (Delta Lake/Spark) and replace manual Excel workflows with automated, well-governed pipelines to meet audit and regulatory standards.

Key Responsibilities

Build and maintain a secure PostgreSQL-based data platform

Lead the shift away from Databricks and spreadsheet‑dependent reporting

Create dimensional data models covering investments, pricing, performance and related domains

Develop reliable ETL/ELT processes in Python

Implement data quality, reconciliation and validation controls

Optimise database performance for analytical and reporting workloads

Ensure compliance with FCA and TPR regulatory guidelines

Set up access controls, security standards and permissioning

Establish monitoring, backup and disaster recovery solutions

Collaborate closely with investment, risk and finance teams

Essential Skills & Experience

5+ years’ experience in data engineering, application development or data platform roles

Strong PostgreSQL knowledge, including indexing, optimisation and partitioning

Background in financial or investment data environments

Advanced SQL and Python skills

Experience migrating data from platforms like Databricks

Confident with dimensional modelling, star schemas, SCDs etc.

Experience within regulated financial services

Desirable

Experience in pensions, asset management or institutional investing

Understanding of performance measurement and attribution

Exposure to Airflow or dbt

Cloud platform familiarity (Azure or AWS)

Knowledge of data governance best practice

About You

Highly detail‑driven with a strong approach to data quality

Comfortable operating in tightly regulated sectors

Able to explain technical concepts clearly to non‑technical audiences

Practical, proactive and solution‑focused

Why This Role?

A rare opportunity to build core investment data infrastructure from the ground up

High visibility and direct engagement with senior stakeholders across multiple business areas

Stable organisation with long‑term goals and purpose

Flexible hybrid arrangement requiring only occasional travel to the London office

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

Where to advertise data engineering jobs UK in 2026: the specialist boards and channels that reach Spark, dbt, Snowflake and platform engineering talent. Data engineers occupy a distinct discipline that sits between software engineering, data science and cloud infrastructure — and the strongest candidates identify firmly with the data engineering community rather than with adjacent roles. General job boards consistently conflate data engineering with data analysis, data science and BI development, producing high application volumes but low candidate quality for specialist pipeline and platform roles. This guide, published by DataEngineeringJobs.co.uk, covers where to advertise data engineering 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 Engineering Jobs UK 2026: What to Expect Over the Next 3 Years

Data Engineering Jobs UK 2026: roles, salaries and the trends shaping UK data engineering hiring over the next three years — Spark, dbt, lakehouse and AI. Data engineering has become one of the most strategically important disciplines in the entire technology sector — and one of the most reliably in-demand. Every organisation that wants to use data to make decisions, train AI models, personalise products, manage risk, or understand its customers depends on data engineers to build the infrastructure that makes any of that possible. Without well-designed, reliable data pipelines, the most sophisticated machine learning model is worthless and the most ambitious analytics strategy is undeliverable. That foundational importance has made data engineering hiring remarkably resilient through the technology market corrections of the past few years. Where headcount reductions fell heavily on some engineering disciplines, demand for data engineers held firm — because the work of building and maintaining data infrastructure cannot be deferred in the way that some product development can. The data keeps coming. The pipelines need to work. But the data engineering jobs market of 2026 is not simply a stable version of what it was three years ago. The discipline has undergone a series of architectural shifts — from batch to streaming, from on-premise data warehouses to cloud-native lakehouses, from hand-rolled pipelines to declarative transformation frameworks, and most recently toward AI-augmented data engineering workflows that are beginning to reshape what the role looks like in practice. The employers hiring data engineers today are asking for a meaningfully different skill set than those hiring three years ago. The candidates who will thrive over the next three years are those who understand where the discipline is heading — which architectural patterns are becoming standard, which technologies are defining the modern data stack, and how the definition of a data engineering career is evolving toward a richer intersection of infrastructure, analytics, and AI enablement. This article breaks down what the UK data engineering 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.
