Job Description

Aquis Exchange is seeking a Database Administrator (DBA) to join our Infrastructure team and take ownership of our database estate. This is a hands-on technical role covering day-to-day administration, reliability, design and support across a varied stack that includes MySQL, Redis, QuestDB (a high-performance time-series database used for market data and operational metrics), Dolt (a version-controlled, Git-for-data SQL database), and Elasticsearch. The successful candidate will be comfortable with mature relational database tooling and open to learning newer, specialist technologies.

The role provides critical support to our Engineering and Operations teams, who rely on performant, well-managed databases to deliver and operate our exchange technology products.


Responsibilities

  • Primary resource responsible to administer, monitor, and maintain the Aquis database estate, ensuring high availability, performance, and reliability.
  • Plan and execute database upgrades, patch management, and version migrations with minimal disruption to production systems.
  • Design, implement, and routinely test backup and restore procedures, ensuring recovery objectives (RPO/RTO) are documented and met.
  • Monitor database health, capacity, and performance; identify and resolve bottlenecks proactively before they impact services.
  • Review and advise on proposed schema changes, working with developers to ensure changes are safe, performant, and aligned with best practices before deployment.
  • Support developers and operations staff with query optimisation, index design, and database access patterns.
  • Act as the primary point of escalation for database-related issues raised by the Engineering and Operations teams.
  • Collaborate with developers on integration between application code and database layers, assisting with connectivity, driver configuration, and troubleshooting.
  • Write and optimise SQL queries for use in Grafana dashboards and reporting front-ends, surfacing operational and business metrics from QuestDB and MySQL.
  • Work with the Engineering team to ensure database metrics and logs are integrated into Aquis monitoring and alerting infrastructure.
  • Manage database user accounts, roles, and permissions in line with the principle of least privilege.
  • Ensure database configurations comply with internal security policies.

Required Qualifications

  • Proven hands-on experience as a DBA or in a database-focused infrastructure/engineering role, ideally in a fast-paced, production environment.
  • Strong working knowledge of MySQL, including installation, configuration, replication, performance tuning, and user management.
  • Hands-on experience with QuestDB is strongly preferred, however candidates with a solid PostgreSQL background and an interest in high-performance time-series workloads are encouraged to apply since QuestDB uses the PostgreSQL wire protocol for queries.
  • Strong working knowledge of PostgreSQL, including query planning, indexing strategies, roles, and connection management.
  • Practical experience with backup and restore strategies across both MySQL and PostgreSQL environments, including point-in-time recovery.
  • Solid understanding of relational database concepts: normalisation, indexing, query execution plans, transactions, and locking.
  • Ability to write complex SQL queries, both for operational and reporting purposes.
  • Experience writing and integrating database queries with Grafana or similar observability and dashboarding tools is desirable.
  • Experience with or interest in version-controlled or branching database systems (e.g. Dolt).
  • Familiarity with Redis and Elasticsearch administration is advantageous.
  • Comfortable working in a Linux-based server environment and with command-line tooling.
  • Experience in a regulated financial services or compliance-driven environment is advantageous, with an understanding of audit and change control requirements.
  • Strong analytical and problem-solving skills, with a methodical approach to diagnosing and resolving incidents.
  • Excellent communication skills-able to translate database concepts clearly for non-specialist colleagues in development and operations teams.
  • Self-motivated and capable of managing competing priorities in a dynamic, high-throughput environment.

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person.

Our Data Environment

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
