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.

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.

You will build software for the following domain:

• Geoscience — geology, geophysics, or petrophysics

Technologies used vary by team and include:

• Languages such as Java, C#, C++, Python, and Type Script
• Frameworks, platforms, and runtimes such as .NET, 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

• 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
• Demonstrate technical leadership by driving design discussions, building alignment across stakeholders, and helping the team make sound engineering decisions
• Coordinate work across multiple engineers when delivering larger initiatives, ensuring technical consistency and timely execution
• Help establish engineering best practices, development standards, and team processes that improve overall delivery quality
• Act as a trusted technical point of contact for a feature area, helping guide priorities and unblock teammates when needed

• 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++, Python, or Type Script (React/Angular)
• 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
• Experience using AI development tools in an effective and productive fashion
• Experience developing agentic workflows in enterprise software
• Experience with cloud-native development including direct exposure to APIs, containerization, Kubernetes
• Experience with CI/CD pipelines
• Demonstrated ability to influence technical direction and drive solutions through collaboration rather than authority
• Strong organizational and planning skills, including the ability to coordinate work across multiple contributors and manage competing priorities

• Background in…
