Senior Software Engineer - Landmark

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 are a technical authority who shapes what gets built and how. 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. You work closely with Product Management and architects on new application design and major enhancements, and you serve as the first technical escalation point when something hard needs to be sorted out in your area. The decisions you make end up in production code that matters.


Strong software engineering fundamentals and the technical depth to independently own complex areas of a product are the primary requirements. Domain knowledge is valuable but not required at hire.


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, TypeScript, and Fortran
• 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 NoSQL databases such as PostgreSQL, SQL Server, Oracle, and MongoDB

Job Duties

• 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
• Design and build new applications and major enhancements in partnership with Product Management and architects
• Serve as the technical authority for your area of the application or architecture: the person the team turns to when a decision is hard or a problem is deep
• 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
• Stay current on tools, practices, and technologies relevant to your area, and drive adoption where they improve the product
• Own security for your area: set coding standards, catch vulnerabilities in design and code reviews, and drive fixes to completion

Qualifications

Required

• 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
• A track record of providing technical leadership across a team or product area
• Communication skills sharp enough to explain a technical trade-off to a product manager and a design choice to a junior engineer with equal clarity

Preferred

• 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.

Candidates with qualifications exceeding the minimum job requirements will be considered for higher-level positions based on their experience, additional job requirements, and current business needs. Depending on their education, experience, and skill level, candidates may be eligible for a range of job opportunities, including Senior Technical Professional and Principal Technical Advisor.

How You Work

The senior engineer who succeeds in this role thinks at the level of the system, not only the feature. 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 do not wait for someone to identify what needs fixing. You see it, own it, and drive it to resolution. You stay technically sharp because you are genuinely curious, and you bring what you learn back to the team. 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.

Why Landmark

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. Here you have the autonomy to make real technical decisions, peers strong enough to challenge you, and problems deep enough to be worth solving well.


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.
