Senior Cybersecurity and Compliance Analyst - Landmark

About Landmark

Landmark, a Halliburton company, builds the software and data platforms that help the global energy industry make better decisions. Our products span subsurface interpretation, well construction planning, reservoir simulation, and digital operations. These are tools used daily by engineers and scientists at the world’s largest energy companies, running as cloud-native SaaS platforms and as enterprise on-premises solutions deployed at some of the world’s largest operators.

As Cybersecurity & Compliance Senior Analyst at Landmark, you will be a hands-on practitioner at the center of how we protect the software the E&P industry depends on. You will partner with engineering, IT, and product teams to make Landmark software genuinely more secure, carrying real accountability across a broad scope of technical and compliance work.

The E&P industry relies on Landmark software to make high-stakes decisions around reservoir modeling, well planning, and production optimization. Our customers — major oil and gas operators worldwide — hold us to a high bar on security and compliance, whether they run our software in their own data centers or subscribe to it as a SaaS platform. You will be the person who keeps that bar high: evaluating controls, analyzing risks, closing gaps, supporting audits, and ensuring that security is embedded in how we build and deliver software rather than added after the fact.

This role suits someone who thrives at the intersection of application security, GRC, and commercial software delivery, and who wants their work to show up in products that the E&P industry depends on.
