We attract and retain the best talent by investing in our employees and empowering them to develop themselves and their careers. Experience the challenges, rewards and prospect of working for one of the world’s largest providers of products and services to the global energy industry.
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, reservoirerred simulation, production optimization, and digital operations. These are tools used daily by engineers and scientists at the world’s largest energy companies and run as cloud-native SaaS platforms and as enterprise on-premises solutions.

At Landmark, that means owning the technical direction for products that oil and gas operators use for high-stakes engineering decisions. You work under broad direction, make architecture decisions that hold up over time, and raise the quality and capability of the teams around you. Strong software engineering fundamentals and the technical depth to independently own complex areas of a product are the primary requirements. Teams build software for domains such as:
Drilling engineering and well planning
E&P; data management and integration
Cloud and platform infrastructure, data services, and developer tooling
AI-assisted analytics, search, and generative AI

Languages such as Java, C#, F#, C++, Python, TypeScript, and Fortran
NET, Eclipse RCP/SWT, JUnit, Angular, React, and Node.js
Cloud platforms including Azure and AWS
Containerization and orchestration tooling such as Docker and Kubernetes
Relational and NoSQL databases such as PostgreSQL, SQL Server, Oracle, and MongoDB

Shape the technical direction of the products and platforms you own across near-term and long-term planning horizons
Scope major technical work: estimate effort, identify risks, and define the delivery approach
Evaluate architecture and implementation for performance, scalability, and security weaknesses,



and drive improvements through to resolution
Lead design and code reviews with a focus on long-term quality, not just correctness
Challenge the delivery process when it produces slow feedback, unnecessary risk, or poor outcomes
Mentor engineers at junior and mid levels through code reviews, technical guidance, and the standard you set in your own work
Own security for your area: set coding standards, catch vulnerabilities in design and code reviews, and drive fixes to completion

Bachelor’s degree in Computer Science, Software Engineering, or a related discipline, or equivalent experience

- 10 or more years of software development experience
- Deep proficiency in at least one of: Java, C#/F# (.NET), C++, Python, or TypeScript (React/Angular/Node.js), and a history of delivering production software in that stack
- Experience designing and owning the architecture of a complex software system or major subsystem, with technical decisions that held up across multiple releases
- Experience with cloud-native development, full-stack or web application development, or data platform technologies

Experience with CI/CD pipelines, containerization, and infrastructure automation
Background in technically complex or scientifically demanding application domains (distributed systems, scientific computing, real-time systems, large-scale data)
Experience integrating machine learning, generative AI, or LLM-based components into production systems
Experience contributing to open-source projects, or integrating open-source components at scale.

Energy industry experience is not required but is a strong plus.



We welcome candidates from all backgrounds and encourage you to apply even if your experience does not match every item in the preferred list.

You bring the experience to know when a technical decision will cost the team later, the credibility to say so clearly, and the follow-through to drive it toward a better outcome. You are comfortable making decisions with incomplete information and pragmatic enough to ship when the solution is sound, even if it is not perfect. You invest in the people around you because you understand that your long-term contribution depends on the quality of the team, not only the quality of your own code.

We build small, high-ownership teams and invest in the quality of every person on them. You will work in a business where software is the product, the work you do matters, and the standards are high. We offer competitive compensation including bonus and long-term incentive programs, a strong career path, and a role where your technical judgment shapes what gets built.
Minimum Qualifications: Minimum qualifications may be acquired through technical schools or equivalent related experience. Candidates having qualifications that exceed the minimum job requirements will receive consideration for higher level roles given (1) their experience, (2) additional job requirements, and/or (3) business needs. Depending on education, experience, and skill level, a variety of job opportunities might be available from the Technical Professional Software Developer - Advisor.
