Octane Systems has over 20 years’ experience in the fuel industry, developing an end-to-end ERP platform for customers across New Zealand, Australia, and Canada.

Our strength lies in building deeply integrated systems — connecting fuel meters, POS platforms, in‑cab truck solutions, and third‑party systems alongside modern web applications. With our ERP platform at the core, we deliver an integrated ecosystem that reduces operational complexity and risk for our clients.

Job Description

Reporting to the Development Manager, you will contribute across both backend/system components and supporting web applications that extend our ERP platform.

• Contributing to and extending our ERP platform through integrations, services, and supporting applications
• Integrating with external systems and APIs
• Working with data flows, imports, and system behaviour
• Supporting and enhancing web‑based applications where required

You will take a structured, logical approach to understanding how systems operate end‑to‑end, and apply this to solving real‑world integration and data challenges.

• Experience building or consuming REST APIs
• Experience with C or C++, or other low‑level/system programming (advantageous)
• Exposure to data transformation or import processes
• Reporting tools (e.g. Crystal Reports or similar)
• Unit testing (e.g. xUnit)
