Job Duties You lead one or more development teams through complex, multi-quarter delivery work on software the E&P industry depends on. The role sits at the intersection of three demands: technical excellence, software delivery, and people leadership. You set technical direction and stay one of the strongest engineers in your area. You own delivery: what the teams ship and how reliably they ship it. You develop and lead the engineers who report to you. The role suits a senior software engineer with proven team leadership experience, or an experienced team lead ready to take on broader scope and formal people management. Your scope varies with the work: a single larger team, a team owning a technically demanding or unfamiliar area, or multiple teams building one product. Strong software engineering fundamentals, proven software delivery leadership, and the ability to develop the engineers around you are all required. Domain knowledge is valuable but not required at hire. Positions are available across a range of teams. Team assignment determines both the product domain and the technologies used. 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 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 and runtimes such as .NET, Eclipse RCP/SWT, JUnit, Angular, React, and Node.js Cloud providers 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 What You Will Do You lead one or more development teams through complex, multi-quarter delivery work and stay close enough to the technology to make the hardest decisions yourself. The work has two dimensions, and you do both every day. Set technical direction and solve hard problems Shape the architecture and technical roadmap of the products you own, and make decisions that hold up across multiple releases Scope major technical work: estimate effort, identify risks, and define the delivery approach Serve as the first technical escalation point when hard problems surface in your area: architectural disagreements, production issues, and deep technical unknowns Evaluate architecture and implementation for performance, scalability, and security weaknesses, and see improvements through to resolution Challenge the delivery process when it produces slow feedback, unnecessary risk, or poor outcomes Stay current on tools, practices, and technologies relevant to your area, and lead adoption where they improve the product Lead teams and develop people Work directly with Product Management and architects to design new applications and major enhancements, and translate product goals into concrete technical plans Manage stakeholder relationships and communicate delivery status, technical trade-offs, and risks upward Define how your teams work and how they coordinate: delivery cadence, ownership boundaries within and between teams, and the bar for hiring and promotion Staff teams effectively by matching people to work based on skill, growth need, and delivery priority Manage and mentor the engineers and mid-level team leads on your teams through performance reviews, development plans, career conversations, and honest feedback Set and enforce code quality, security, and architectural standards across your teams through reviews, direct feedback, and the technical culture you build Own the technical debt in your area: decide what actually matters, get it into the delivery plan, and see it resolved Qualifications Bachelor’s degree in Computer Science, Software Engineering, or a related discipline, or equivalent experience 10 or more years of software development experience, including proven experien
