Senior Data Engineer

LET’S CUT STRAIGHT TO IT

At Severn Trent, our people are at the heart of everything we do. We’re in the top 5% of utility companies worldwide for employee engagement, and we’re equally proud of our strong Glassdoor score — reflecting how much our people love working here.  

Join us to make a positive impact on the environment and our communities, while being valued and supported in a truly inclusive workplace. 

If you want to do more, because you care, we want you on our team. 

LET’S TELL YOU MORE

Severn Trent is building a brand new data platform and we’re looking for a Senior Data Engineer with strong, hands-on engineering depth to help build it. You will be working directly on a Databricks-based lakehouse, with Informatica IDMC used for enterprise-grade ingestion and integration.

Key Accountabilities in the role include:-

Databricks pipeline engineering: Design, build and operate Spark pipelines on Databricks, including handling schema evolution, incremental loads, backfills, and failure recovery.
Integration and orchestration (IDMC): Use Informatica IDMC to implement governed, repeatable ingestion patterns from source systems into curated lakehouse layers.
Lakehouse modelling: Build curated bronze, silver and gold datasets that are performant, testable, and fit for downstream analytics and data products.
Data quality and reliability: Implement automated data quality checks, validations and controls that prevent bad data from silently reaching consumers.
Performance and cost optimisation: Actively tune Spark workloads, storage layouts and execution patterns with an awareness of cloud cost and runtime behaviour.
Dual-run and migration delivery: Support and stabilise existing Synapse workloads while contributing to migration and net-new delivery on Databricks.
Technical leadership: Set engineering standards through code reviews, patterns and practical mentorship rather than documentation alone.

You'll be based at our Severn Trent Centre head office in Coventry. You’ll work within our dedicated Data Engineering team of 14. With this being such a critical role, we’re looking for someone who can join us 37 hours a week, Monday to Friday.

HOW WE WORK

You'll join a caring culture that collaborates to achieve, grow, and develop. Our employee engagement scores are among the highest globally in energy and utilities. That’s why, we value in-person moments to keep our culture alive but also understand the flexibility working from home can bring. So, you'll usually find us in the office, but working from home is supported, when you need it.

WHAT WE’RE LOOKING FOR

We are looking for engineers who are genuinely strong at data engineering as a craft, not generalists who have only used platforms at a surface level.

You will have:

Strong experience building PySpark-based pipelines that run reliably in production.
A solid grasp of Spark execution behaviour, including partitioning, shuffles, joins and performance trade-offs.
Hands-on experience with Databricks in a real delivery environment.
Experience using Informatica IDMC or equivalent enterprise integration tooling to build governed ingestion flows.
Strong SQL skills and confidence working across raw, curated and consumer-ready data layers.

Experience operating or supporting Azure Synapse is useful during the transition, but it is not the long-term focus of the role.

Skills and experience are important, but character, positivity, and a caring attitude matter too.  We welcome people from all walks of life and celebrate individuality as we know diverse minds, experiences and backgrounds help us to learn and better serve our communities. We seek people who get involved, want to be part of something bigger, and make a difference because they care.

HOW WE’LL REWARD AND CARE FOR YOU IN RETURN

It's not just a job; it's a career. We offer benefits that reward great work and award-winning training to help you reach your potential. Plus, you'll contribute to the environment and community too. Here are some of our favourites:

28 days holiday + bank holidays (and the ability to buy/ sell up to 5 days per year)
Annual bonus scheme (of up to £2,225, which is subject to eligibility)
Family-friendly policies (including a year off fully paid maternity and adoption leave)
Leading pension scheme – we will double your contribution (up to 15% when you contribute 7.5%)
Sharesave – the chance to buy Severn Trent plc shares at a discounted rate
Dedicated training and development with our Academy
Electric vehicle scheme and retail offers
Two paid volunteering days per year
