Senior Data Architect - Landmark

About Landmark

Landmark, a Halliburton company, builds 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 tools are used daily by engineers and scientists at the world’s largest energy companies. The Engineering organization owns the infrastructure, cloud operations, and deployment frameworks that make Landmark’s product portfolio available to customers across the globe: in the cloud, at the customer site, and in environments where connectivity cannot be assumed.

About the Role

As the Senior Data Architect at Landmark, you will architect and design the next‑generation data platform on which Landmark applications will be built. While Platform Delivery Managers own the team and its delivery commitments, you own the architecture. You will represent the data platform in Landmark’s architecture community, partnering with the Chief Architect to ensure that all teams understand the data platform and the best practices to use it. You will also review application architectures to ensure proper adoption and usage of the data platform.

Responsibilities

• Define and maintain the architecture for Landmark’s data platform layer, including architecture diagrams, documentation, and architectural decision records.
• Partner with Landmark’s security team to ensure the data platform architecture satisfies security requirements and compliance frameworks—including SOC 2, regulated‑site certification standards, and enterprise security policy—and encode those requirements in the platform’s architectural standards.
• Define the architectural patterns for tenant data isolation and data residency.
• Work with architects in domain application teams to explain the proper use of the data platform.
• Review application architectures to verify proper usage of the data platform.
• Serve as the data platform representative in Landmark’s architecture community.

Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, Information Systems, or a related STEM discipline, or equivalent professional experience.
• 10+ years of professional software engineering experience, with significant time spent on data layers, including exposure to relational and unstructured data, data virtualization and federation, ETL, lake houses, medallion architectures, and data platforms.
• Demonstrated track record of defining architectures at a platform level.
• Strong written communication skills, with the ability to produce architectural specifications, decision records, and interface contracts that are precise enough to be implemented and clear enough to be understood by teams that did not write them.
• Demonstrated ability to influence technical peers across teams through the quality of architectural reasoning rather than organizational authority.
• Experience with at least one of AWS and Azure, their database offerings, and other services such as object storage and Kubernetes.
• Preferred: Experience with both AWS and Azure native services.
• Preferred: Background in oil & gas.

Why Landmark

This role owns one of the key underpinnings of Landmark’s solutions – a comprehensive, modern, performant data foundation. You will work with the platform engineering teams and the Chief Architect to define the data foundation that the rest of Landmark builds on top of. Your architectural decisions will affect every product team in the organization and every customer who deploys Landmark software. You will have direct access to the architecture community, executive sponsorship through the CTO, and relationships with security, compliance, and enterprise stakeholders needed to make architectural commitments that hold.

We build small, high‑ownership teams and invest in the quality of every person on them. Engineers co‑author product strategy alongside product management and domain science; the art of the possible is an engineering contribution, not a function that sits upstream. The experiences we design ensure that customers remain in control of the decisions that matter, never passengers in their own workflows. We offer competitive compensation, a strong IC career ladder with a visible path to Principal Architect, and a business where architecture quality is a direct competitive differentiator in enterprise and regulated‑market deals.
