Database Engineer

Database Engineer – PostgreSQL

£50,000 | Fully Remote, UK | Permanent

We’re working with a growing data and technology business looking for a Database Engineer to take ownership of improving the PostgreSQL databases behind its live, data-intensive platforms.

This is not a traditional DBA position. You’ll work closely with software developers and DevOps engineers to improve database performance, optimise the way applications access data and help shape better database solutions as the platform continues to scale.

The business processes large volumes of time-sensitive, high-throughput data, so performance, efficient retrieval and latency really matter. There is also a substantial archive of historical data that needs to become easier and more efficient to organise, search and retrieve.

This would be a great opportunity for someone who enjoys finding database problems, understanding why they are happening and implementing practical solutions.

What you’ll be doing

Reviewing and improving PostgreSQL schemas, indexes, constraints and SQL queries

Investigating slow queries using execution plans, database statistics, logs and monitoring

Optimising joins, repeated lookups and application data-access patterns

Working closely with developers to improve database design before new features are released

Improving how large volumes of historical data are organised, archived, indexed and retrieved

Designing views, materialised views and reporting structures where appropriate

Investigating locking, transaction and concurrency issues

Planning safe schema changes and data migrations

Measuring database performance, query load and storage growth

Helping establish practical SQL and database design standards across the engineering team

Working alongside DevOps on monitoring, backup and recovery

What we’re looking for

You’ll need strong hands-on experience with PostgreSQL in a production environment, alongside excellent SQL skills.

We’d particularly like to speak with people who have:

Strong PostgreSQL and SQL experience

Practical query optimisation and performance-tuning experience

Experience working with indexes and execution plans

Good knowledge of relational data modelling, constraints and data integrity

Experience working with large datasets and designing efficient ways to search and retrieve information

Knowledge of transactions, locking and concurrency

Experience making safe database changes in production

Worked closely with software developers to improve application database access

The ability to independently investigate problems and recommend practical solutions

Experience with AWS RDS, partitioning, materialised views, data archiving, S3, Redis or DynamoDB would be useful, but these are not essential requirements.

Experience working with real-time data, low-latency systems, high-throughput platforms, trading, gaming or other data-intensive environments would also be particularly interesting.

The environment

The engineering team is 100% remote across the UK, so you’ll need to be comfortable working independently while remaining closely connected with developers and other engineers.

The company values people who are proactive and comfortable taking ownership. You won’t simply be given a list of database tasks to complete. You’ll be encouraged to investigate the existing environment, identify opportunities for improvement and bring forward your own solutions.

Why consider it?

This is a newly created position, giving you the opportunity to become the dedicated database specialist within a growing engineering team.

You’ll have the chance to:

Take genuine ownership of PostgreSQL performance and database engineering

Solve interesting problems involving live, time-sensitive data

Improve access to a substantial historical dataset

Work closely with an experienced development and DevOps team

Influence database standards and future technical decisions

See measurable results from the improvements you introduce

Work fully remotely anywhere in the UK

Salary: £50,000

Location: Fully remote, UK

Contract: Permanent, full-time

If you’re a PostgreSQL-focused engineer who enjoys performance optimisation, solving complex data problems and taking ownership of improvements, we’d be keen to hear from you.
