Senior Software Developer

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.

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

You 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 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 Type Script
• 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 No
  
  SQL databases such as PostgreSQL, SQL Server, Oracle, and MongoDB

What You Will Do

• 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 Type Script (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
• Clear written and verbal communication, including the ability to explain technical decisions and trade-offs to teammates and stakeholders

Preferred

• Experience with cloud-native development, full-stack or web application…
