Job Description

We are looking for a skilled Backend software engineer to maintain, extend, and improve our Pipelines integration platform — a distributed data pipeline system built on .NET Framework 4.8 that ingests, parses, stages, and reports on operational data from multiple third-party systems across the energy/drilling industry. The successful candidate will also take the lead in migrating the current .NET Framework application to .NET Core.

What You Will Work On

The platform is a C# / .NET Framework 4.8 Windows Service solution consisting of:

• Customer adapter services — customer-specific integration services that orchestrate data pipelines
• Reusable API libraries — shared integration adapters for third-party systems including Graph API, REST API, SQL, and NoSQL
• Pipeline stages — each managed via Azure Service Bus message queues
