At Smart, our mission is to transform retirement, savings and financial wellbeing, across all generations, around the world.

The Role

As part of the Backend Engineering function, and reporting to the Data Engineering Tech Lead, the Data Engineer will be working on planning, engineering and maintaining clients’ data warehouses, ETL processes and other data pipelines. As Smart’s client base grows we will be delivering data pipelines for each client who requires it. This is an opportunity to be involved in the design, deployment and maintenance of data pipeline solutions across multiple clients.

The Smart Data Engineering team is accountable for:

  • Maintenance of the UK Smart Data Warehouse and associated ETL routines
  • Maintenance of the underlying data for BI reports and dashboards, used throughout the organisation
  • Data engineering support when migrating large new clients onto Smart’s Keystone platform
  • Validating significant changes to system functionality, particularly in relation to those that might impact members’ pension holdings
  • Maintaining client data extracts which integrate with some of our clients’ systems
  • Implementing new and/or improved data pipelines which help expand core Keystone functionality, empowering users with more immediate and direct access to critical data

About you

As a Data Engineer you’ll get a kick out of interacting with data in all its forms. More importantly, you get excited by the prospect of using data to solve problems. If you can use your skills to solve a business problem, that’s a great day’s work for you.

You will need to have strong skills in database technologies as well as Python. You’ll also be able to talk to techies and non-techies alike and make suggestions about solutions to problems that can be understood and implemented.

Smart strives to provide a comfortable, relaxed working environment and the Data Engineering team is no different. We take great pride in our work and strive to hit sometimes challenging deadlines, but we like to make sure that people are enjoying their work as we do it. This is not an easy balance to strike but being open and honest with each other is an important step in the right direction.

Main Responsibilities:

  • Work with stakeholders to identify new data sources that would add business value
  • Implementing new data pipelines for new or existing clients
  • Maintaining existing data pipelines and handling errors as necessary
  • Monitoring the performance, security and scalability of the data pipelines
  • Evaluating the existing data warehouse solution to determine necessary updates and integration requirements and make sure final designs meet the clients needs
  • Impact assessing change requests, ensuring that changes don’t break existing workflows

  • 5+ years’ work data engineering, with proven experience in Data Modelling
  • Experience in writing, troubleshooting, and debugging complex SQL queries
