Senior Technical Professional - Technical Advisor- Software Dev - Landmark

Date: Aug 17, 2026

Location: Houston, TX, US, 77032

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 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.

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 TypeScript
• 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

• 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

Qualifications

• 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 TypeScript (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

Preferred

• Background in enterprise software, SaaS platforms, or technically demanding application domains (scientific computing, real-time systems, large-scale data)
• Experience serving as a technical lead, feature lead, or informal team lead on software projects
• Experience coordinating the work of small engineering teams, including planning, estimation, risk management, and delivery tracking
• Demonstrated potential for engineering leadership through ownership, initiative, mentoring, and cross-functional collaboration

Candidates having qualifications that exceed the minimum job requirements will receive consideration for higher level roles given (1) their experience, (2) additional job requirements, and/or (3) business needs. Depending on education, experience, and skill level, a variety of job opportunities might be available, Principal Software Development, and Technical Advisor Software Development.

How You Work

The engineer who succeeds in this role brings independent judgment to their work and applies it consistently. You own your assignments end to end, communicate clearly when something is off track, and treat code reviews as a genuine quality tool rather than a formality. You are comfortable working across time zones, adaptable when requirements shift, and focused on delivery outcomes rather than task completion. You pick up new tools and techniques on your own, evaluate them critically, and bring the ones that work to your team. You help the engineers around you improve because you understand that team quality compounds over time.

You naturally step into leadership opportunities when they arise. You build credibility through technical excellence, sound judgment, and consistent delivery. You can influence decisions, align stakeholders around a common direction, and help teams navigate ambiguity. While you may not currently have direct management responsibilities, you have the interest and potential to grow into a team leadership role over time.

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. You will own real work that ships, learn from engineers who push you, and grow into the kind of engineer the team relies on.

We offer competitive compensation, a strong career path, and a role where you own what you build and your impact is visible. For engineers with leadership aspirations, this role provides opportunities to mentor others, influence technical direction, drive key initiatives, and grow toward future technical leadership or team lead responsibilities while remaining deeply engaged in software development.

At Halliburton, we’re committed to providing you and your family with a comprehensive and affordable benefits package – which means we offer support for your physical, emotional, financial and parental needs, both now and in the future. When you join our team, you’ll have access to a wide range of resources designed to help you thrive at work and at home.
