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

This is a hands‑on software engineering role. We are looking to recruit an experienced Senior Software Engineer to design, develop, and modernize high-performance Rock Physics desktop and cloud applications. Reporting to the Team Lead and working closely with the Product Owner, you will own the technical direction of production software — writing code daily, reviewing pull requests, and driving architectural decisions.

Key Responsibilities

• Design & build software — Architect, implement, and maintain complex desktop and cloud applications using modern software engineering practices (design patterns, SOLID principles, automated testing, continuous integration/delivery).
• Modernize legacy systems — Lead migration of mature C/C++ codebases to modern languages, runtimes, and UI/UX frameworks while preserving scientific accuracy and performance.
• Leverage AI‑assisted development — Actively adopt AI‑powered tools (e.g., Copilot, code‑generation, automated testing assistants) to accelerate delivery and improve code quality; collaborate on architecture — Partner with the Team Lead and Product Owner to translate requirements into sound, maintainable technical solutions the team can implement and iterate on.
• Mentor & lead technically — Coach junior and mid‑level developers through code reviews, pair programming, and knowledge‑sharing; foster a culture of engineering excellence. Communicate clearly — Escalate risks, trade‑offs, and progress in a timely, structured manner to technical and non‑technical stakeholders. Stay current — Continuously evaluate and adopt emerging languages, frameworks, cloud services, and AI/ML tooling relevant to the product.

Required Qualifications

• 5+ years of professional software engineering building and shipping complex, production‑grade applications — not solely scripting, prototyping, or research. Strong proficiency in C#/.NET; and also C/C++; demonstrated ability to work across both languages in a single product ecosystem. Undergraduate (or higher) degree in Computer Science, Software Engineering, or a closely related engineering discipline.
• Comfort and curiosity with AI‑assisted development tools and a track record of staying ahead of technology trends. Experience with cloud architecture (AWS, Azure, and/or Google Cloud). Proven experience with software engineering fundamentals: object‑oriented and component‑based design, design patterns, unit/integration testing, version control (Git), and code review workflows. Hands‑on CI/CD experience — building, configuring, or maintaining automated build and deployment pipelines.
• Experience modernizing legacy software — migrating codebases from older languages or frameworks to current platforms, including UI/UX modernization. Self‑motivated and collaborative; thrives in a team environment and takes initiative without direction. Excellent analytical, communication, and problem‑solving skills.

Minimum Qualifications: Minimum qualifications may be acquired through technical schools or equivalent related experience. 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 from the Technical Professional Software (Senior - Principal)
