Mission

The Software Engineer will own the development of cross-platform applications that embed AI directly into exploration and production workflows. From subsurface characterization to production surveillance, you'll build software that touches the full E&P lifecycle. You'll be part of aN integrated technical team that includes geoscientists and petroleum engineers, where domain expertise and engineering skills aren't siloed but shared.

Responsibilities

• Analyze, design, develop and maintain products and assist in their commercialization in agreement with project technical and timing objectives.
• Ensure that product code and artifacts are managed and safeguarded in a configuration management system in accordance with procedures and guidelines.
• Apply usability procedures and principles as defined at the project or product-line level or through customer input.
• Evaluate alternative implementations and select the one that maximizes the value of the product and minimizes the risk and technical debt.
• Validate software readiness and quality through systematic testing, automation, and verification practices.
• Provide technical support to internal and external customers.

Essential Requirements

• BSc in Computer Science, Engineering or related field or equivalent experience.
• Strong Object-Oriented Design.
