We’re looking for a hands‑on Analytics Engineer to optimise high‑volume time‑series data powering Grafana dashboards.

This role is focused on performance. We have large volumes of FX price data flowing through SQL/Athena into Grafana, and we need someone who knows how to structure, aggregate and tune that data so dashboards remain fast and usable - even across longer time ranges.

This is not an infrastructure or Dev Ops role. It’s about query optimisation, aggregation strategy and dashboard performance tuning.

• Optimising large SQL datasets feeding Grafana dashboards
• Designing bucketing, windowing and aggregation strategies
• Improving performance across short and long time ranges
• Reducing query latency and unnecessary data scans
• Working closely with stakeholders to refine data visualisation requirements

• Strong SQL skills (complex aggregations, window functions, time‑based grouping)
• Hands‑on experience building and tuning Grafana dashboards
• Experience working with large / high‑volume datasets
• Proven track record of improving dashboard or query performance

• S3 or serverless SQL environments
