An Auckland or remote NZ opportunity for a C# specialist to lead backend modernisation, linking live data pipelines with advanced math models!
Why You’d Like It
If you are a senior engineer who thrives on autonomy, loves the intersection of high-performance backend code and data science, and hates being micromanaged, this is the one. You will step into a role where you genuinely own the technical direction, moving a sophisticated trading environment toward a modern, serverless architecture. Plus, with a hybrid setup out of Auckland CBD or full remote flexibility nationwide, you can work exactly how you work best.

The Story
As wholesale markets become faster and more data-reliant, this team is scaling up to stay ahead of the curve. They are moving away from legacy infrastructure and leaning heavily into cutting-edge cloud automation, serverless tech, and robust data pipelines. To make this shift seamless, they need a seasoned engineer who can bridge the gap between heavy C#.NET engineering and complex quantitative data models.

Company Profile
This established player in the APAC energy and technology sector operates at the absolute forefront of wholesale market operations. They build and run the high-volume data engines and forecasting platforms that drive real-time business insights. It is a collaborative, agile team of data specialists and infrastructure engineers who prize efficient architectures over corporate bureaucracy, which is exactly why they deliberately bypass unnecessary framework complexity in favour of clean, scalable cloud solutions.

Your Role
You will take ownership of the core data processing pipelines and quantitative execution platforms that power live wholesale market operations.
  • Bridge the Tech Stack: Build and scale low-latency Web APIs and background workers in C#.NET, ensuring seamless communication with quantitative models written in R and Python.
  • Modernise the Cloud: Champion the transition to serverless cloud solutions using AWS Lambda, ECS, and Batch, while standardising environments with Terraform.
  • Optimise Data Pipelines: Design and manage robust SQL backends and ETL pipelines to ingest and structure massive external streaming datasets like weather matrices.
  • Drive Automation & Observability: Prototype next-generation AI and event-driven workflows using N8N, while monitoring ecosystem health and performance using DataDog.
Benefits
  • True Autonomy: The freedom to define how your work looks without micromanagement.
  • Flexible Working: Work from a modern Auckland CBD office or go fully remote from anywhere in New Zealand.
  • Modern Tech Stack: Work with AWS serverless architectures, Docker, and IaC without unnecessary enterprise bloat.
  • Competitive Package: A strong salary plus benefits package aligned with senior market rates.
Your Fit
You are a seasoned .NET Developer who is comfortable engineering heavy backend systems and managing cloud infrastructure. You have strong SQL skills and solid commercial experience provisioning AWS environments via Terraform. Ideally, you have worked alongside data scientists, or you have a natural curiosity for financial markets, algorithmic trading, or data-heavy automation.
