Job description

We are looking for the right people — people who want to innovate, achieve, grow and lead. 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.

Job Duties

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, 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 Role

This role spans the full early-career range. We are hiring new graduates as well as engineers with up to five years of professional experience. If you are a few years in and looking for stronger mentorship, a more technically serious codebase, or a clearer growth path than your current role offers, this posting is for you. Your experience will be reflected in your level, scope, and compensation at offer.

You join a delivery team and start writing production code immediately. You build software with your team that oil and gas operators use every day for real decisions. You debug issues in systems that connect to live data, write features that operators depend on, and learn how professional software teams ship quality code at scale.

You receive regular guidance from experienced engineers and participate in code reviews from the start. Over time, you grow your technical skills and your understanding of the product domain, and you build the habits that make an engineer effective over the long term. We hire for potential and train for success.

Positions are available across a range of teams. Team assignment determines both the product domain you work in and the technologies you use.

Teams Build Software For Domains Such As

• Geoscience — geology, geophysics, or petrophysics
• Drilling engineering and well planning
• Reservoir engineering and modeling
• Production engineering and optimization
• E&P data management and integration
• Cloud and platform infrastructure, data services, and developer tooling
• AI-assisted analytics, search, and generative AI

Technologies Used Vary By Team And Include

• Languages such as Java, C#, F#, C++, Python, and TypeScript
• Frameworks, platforms, and runtimes such as .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
• Infrastructure automation tools such as Terraform, Ansible, Helm, and Argo CD/Flux
• Relational and NoSQL databases such as PostgreSQL, SQL Server, Oracle, and MongoD

What You Will Do

• Build, test, and ship features for products in active use by energy companies worldwide
• Debug and fix defects in production systems, learning how large-scale applications behave under real conditions
• Write and maintain automated tests as part of the team’s standard delivery workflow
• Participate in code reviews: read your teammates’ code, receive feedback on yours, and learn the codebase through both activities
• Follow secure coding practices, triage security issues when they arise, and apply fixes to deliver secure applications
• Contribute to technical documentation for the systems and features you work on
• Work within a distributed team across time zones, communicating clearly and consistently about your progress and blockers
• Research and evaluate open-source tools and libraries that can improve the systems you work on
• Grow your understanding of the product domain through the work itself

Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, or a related discipline, or equivalent professional experience
• Mininum of 3 years of software development experience
• Working knowledge of at least one modern programming language and standard development tooling (version control, build systems, testing frameworks)

Preferred

• Experience contributing to a shared codebase with other engineers
• Exposure to cloud platforms (Azure, AWS), web application development, or data systems
• Exposure to CI/CD or infrastructure automation tools
• Interest in technically demanding application domains such as scientific computing, applied AI/ML, real-time systems, large-scale data processing, or similar

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.

How You Work

The engineer who succeeds in this role is technically curious and takes their craft seriously. Whether you are writing your first production code or already have a few years behind you, you pick up new tools and techniques quickly, ask good questions when you are unsure, and follow through on the tasks you own. You treat code reviews as a place to both learn and contribute, and you communicate clearly with teammates across time zones.
