Senior Data Engineer (Python, AWS)

MCS Group is exclusively partnering with a successful, fast-growing technology company as it expands its Data Engineering team. This is a senior, hands-on role for an experienced engineer who is highly confident working with Python, SQL and AWS. You will help build a modern data platform that transforms large volumes of complex, proprietary data into scalable, analytics, AI capabilities and customer-facing product features. This is not a traditional reporting, analytics or data visualisation role. Instead, this is very much an engineering role where you will be building production-grade data services, APIs and pipelines that sit at the heart of the company's technology products.
This is a remote position for candidates based in the UK and sponsorship is not available.
The Role
The Senior Data Engineer will work closely with software engineers, product teams, data specialists and technical leadership to design and deliver reliable, scalable data solutions.
Your responsibilities will include:
Building robust data pipelines and backend data services using Python and SQL
Designing data APIs, semantic layers and curated datasets
Developing cloud-native data solutions within AWS
Structuring and modelling complex engineering and simulation data
Supporting analytics, machine learning and AI-driven product capabilities
Working with Product Managers to translate requirements into scalable technical solutions
Collaborating with Data, AI, BI, QA and Software Engineering teams
Contributing to CI/CD, infrastructure-as-code and DevOps practices
Maintaining high standards across data quality, testing, monitoring and performance
Evaluating new tools, frameworks and architectural approaches as the platform evolves
What We're Looking For
Strong commercial experience in data engineering or backend software engineering
Advanced Python development skills
Strong SQL skills, including complex querying and data modelling
Hands-on experience building and deploying solutions within AWS
Experience developing production-grade data pipelines and services
Practical knowledge of ETL and ELT tooling such as Airflow, dbt, Airbyte, Temporal or Fivetran
Experience with data warehousing and modern data architecture patterns
A strong understanding of data validation, testing, monitoring and quality
Experience working within a software product or technology-led environment
Strong communication skills and the ability to work across technical and non-technical teams
Salary
Up to £90,000 plus benefits
