We're supporting a technology-led organisation building high-throughput, event-driven systems operating at scale.

They are looking for 2 Senior Engineers (1 Python, 1 .NET/C#) to work on a time-series focused platform powering Real Time data ingestion, storage, and analytics.

This is not a standard Back End role.

If you haven't actually worked hands-on with time-series data in production, this won't be the right fit.

What You'll Be Doing
  • Building API-driven Back End services handling high transactional workloads
  • Designing and optimising time-series data pipelines (ingestion storage query)
  • Working with event-driven architectures using Azure Service Bus
  • Modelling time-series datasets for performance and scalability
  • Implementing retention policies, partitioning strategies, and downsampling
  • Optimising query performance across large-scale datasets
  • Deploying services into Azure (AKS, Functions, App Services)

Core Requirements (Non-Negotiable)
  • Proven, hands-on experience with time-series data in productionNot theoretical
  • Not "touched it once"
  • You've built, scaled, and optimised it
  • Experience with:
  • InfluxDB and/or Azure Data Explorer (ADX/Kusto)
  • Kusto Query Language (KQL) (for ADX users)
  • Strong understanding of:
  • Time-series data modelling
  • Ingestion pipelines
  • Query optimisation
  • Partitioning strategies
  • Hot vs cold data layers
  • Retention & downsampling

Tech Environment
  • Python or C#/.NET
  • Azure (AKS, Functions, App Services, Storage)
  • Azure Service Bus (event-driven systems)
  • Docker/Kubernetes
  • Azure Monitor/App Insights/Datadog
  • GitHub Actions (CI/CD)

What They're Looking For
  • Engineers who have worked on long-lived, production platforms
  • Strong focus on reliability, scalability, and performance
  • Comfortable operating in high-load, distributed systems
  • Able to explain real implementations, not just concepts

Why This Role
  • Proper engineering challenge (not CRUD/web apps)
  • Work on Real Time, high-volume data systems
  • High-impact project with immediate demand for delivery
  • Outside IR35, strong rates, quick turnaround

If you've genuinely built and scaled time-series systems, this is a very strong contract.

If you haven't, this one won't land.
