Senior Database Administrator (Open-Source / FinTech Stack)
About the Company
We are partnering with a highly successful, high-growth financial technology firm and regulated European market operator. Known for their disruptive approach and cutting-edge trading technology, they handle massive volumes of real-time market data at microsecond speeds.
Instead of traditional, restrictive corporate database structures, they have built a decentralized open-source data architecture engineered purely for extreme performance and scalability.
The Opportunity
We are seeking a Senior Database Administrator to join a talented Infrastructure team and take true ownership of a varied, modern database estate.
This is a hands-on technical role where you can step away from legacy monolithic systems. You will manage a highly specialized ecosystem built for speed, data version-control, and deep observability. Working closely with Engineering and Operations teams, you will ensure high availability, advise on schema design, and guarantee that core data engines run flawlessly.
The Tech Stack
- Core Relational: MySQL & PostgreSQL
- High-Performance Time-Series: QuestDB (Used for massive market data ingestion & operational metrics)
- Version-Controlled SQL: Dolt (Git-for-data branching technology)
- Caching & Search: Redis & Elasticsearch
- Observability: Grafana & Linux-based monitoring tools
Key Responsibilities
- Estate Ownership: Administer, monitor, and scale the database ecosystem to ensure continuous high availability and reliability.
- Developer Collaboration: Partner closely with engineering teams on schema design, query optimization, and database access patterns.
- Build Observability: Write complex SQL queries to surface vital business and operational metrics onto Grafana dashboards.
- Infrastructure Resilience: Plan and execute seamless upgrades, patch management, and routinely test point-in-time recovery (RPO/RTO) strategies.
What We Are Looking For
- Strong Open-Source DBA Background: Proven experience as a DBA or Database Engineer managing production-scale MySQL environments.
- PostgreSQL Expertise: Solid knowledge of Postgres query planning, indexing, and connection management. (This is highly transferable for their time-series tech, which utilizes the Postgres wire protocol).
- Linux Native: You are entirely comfortable working in Linux-based server environments using command-line tooling.
- Tech Curiosity: A genuine interest in learning and managing specialized, modern data tools (such as time-series engines or branching database systems).
- FinTech or High-Throughput Experience: Background working in a regulated financial services, trading, or high-throughput environment is highly advantageous.
The Culture
The team operates on a culture of trust, collaboration, and continuous improvement. It is a fast-paced but supportive environment where new ideas are actively encouraged, and engineers are empowered to make a direct impact on the core technology products.
Location: London or Paris (Hybrid - 3 days in office)
Employment Type: Full-time, Permanent
- Salary: £80/95k + Bonus + Benefits
