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 opportunity of working for one of the world’s largest providers of products and services to the global energy industry. About LandmarkLandmark, 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, 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.About the RoleYou own the full development cycle for the features and systems your team assigns you. At Landmark, that means working on software that oil and gas operators depend on for high-stakes decisions. You take a feature from specification through design, implementation, testing, and delivery with minimal supervision and enough judgment to make good technical decisions along the way. You contribute to code reviews, improve the codebase and processes around you without waiting to be asked, and help junior engineers grow. The quality of what you build shows up in production software used by operators worldwide.Strong software engineering fundamentals are the primary requirement. Domain knowledge is valuable but can develop on the job.Positions are available across a range of teams. Team assignment determines both the product domain you work in and the major technologies you use.Teams build software for domains such as:Geoscience — geology, geophysics, or petrophysicsDrilling engineering and well planningReservoir engineering and modelingProduction engineering and optimizationE&P data management and integrationCloud and platform infrastructure, data services, and developer toolingAI-assisted analytics, search, and generative AI.Technologies used vary by team and include:Languages such as Java, C#, F#, C++, Python, and TypeScriptFrameworks, platforms, and runtimes such as .NET, Angular, React, and Node.jsCloud platforms including Azure and AWSContainerization and orchestration tooling such as Docker and KubernetesInfrastructure automation tools such as Terraform, Ansible, Helm, and Argo CD/FluxRelational and NoSQL databases such as PostgreSQL, SQL Server, Oracle, and MongoDB

Bachelor’s degree in Computer Science, Software Engineering, or a related discipline, or equivalent experience
5–10 years of software development experience
Strong proficiency in at least one of: Java, C#/F# (.NET), C++, Python, or TypeScript (React/Angular/Node.js)
Experience owning the full development cycle: requirements analysis, design, implementation, testing, and delivery
Experience debugging production software and tracing root causes that span multiple components or layers

Nice To Haves

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 enterprise software, SaaS platforms, or technically demanding application domains (scientific computing, real-time systems, large-scale data)
Exposure to integrating machine learning, generative AI, or LLM-based components into application features
Experience mentoring less experienced engineers
Energy industry experience is not required but is a strong plus.

Responsibilities

Own features end to end: analyze requirements, design solutions, write the code, test it, and ship it
Break complex specifications into concrete tasks with realistic schedules and flag risks early
Proactively identify and fix weaknesses in the codebase, the test coverage, and the development process
Investigate and resolve production defects, and trace root cause when symptom and source are not in the same place
Apply secure coding practices, surface vulnerabilities in code reviews, and fix security issues as they arise
Review code from other engineers with the same rigor you expect on your own work
Evaluate and integrate open-source tools and libraries where they improve the systems you work on
Mentor junior engineers through code reviews, pairing, and direct technical guidance
