• Define and enforce coding standards, architectural patterns, and best practices across mobile and backend development.
• Provide technical leadership and mentorship to other developers, conducting code reviews and guiding design decisions.
• Collaborate with digital solutions engineers, product owners, and stakeholders to translate complex business requirements into scalable and maintainable solutions.
• Own technical decision-making across the stack, ensuring alignment with long-term architectural strategy.
• Optimize application reliability, security, scalability, and performance across mobile and backend systems.
• Lead refactoring efforts and drive continuous improvement initiatives to enhance code quality and maintainability.
• Guide implementation of responsive user interfaces that support a varied audience, from field technicians on phones to customers on tablets.
• Troubleshoot and resolve complex technical issues across environments.
• Oversee CI/CD pipelines, deployment strategies, and DevOps best practices.
• Evaluate and introduce emerging technologies, tools, and frameworks to improve development efficiency and product quality.
• Participate in Agile development methodologies and help drive estimation, sprint planning, and technical backlog refinement.
• Provide technical input into roadmap planning and long-term product strategy.

• Occasionally travel to well-sites, trade shows, and customer offices to better understand user needs and support solution delivery.

Required Knowledge, Skills, and Abilities:

• Strong leadership and communication skills, with the ability to convey complex technical concepts to both technical and non-technical stakeholders.

• Advanced proficiency in Python, including modern async frameworks such as FastAPI.
• Extensive experience designing and building RESTful APIs and distributed systems.
• Deep experience with Flutter for cross-platform mobile application development.
• Strong understanding of mobile architecture patterns, state management (especially bloc), and scalable UI design.
• Experience designing scalable system architectures and making sound technical tradeoffs.
• Functional knowledge of authentication and authorization strategies (Auth0, JWT, role-based access control, etc.).
• Strong understanding of relational (PostgreSQL, MySQL) and/or NoSQL databases.
• Experience with cloud computing services and tools, especially Azure and/or Google Cloud Platform.
• Experience designing and supporting CI/CD pipelines and deployment workflows.
• Proficiency with Git and version control best practices, including branching strategies and pull request workflows.
• Strong testing practices, including unit, integration, and end-to-end testing strategies.

• Ability to guide technical direction while remaining hands-on in development.

Minimum Qualifications:

• Bachelor’s degree in Computer Science, Engineering, or related field, or equivalent experience.

• 6+ years of professional software development experience.
• 2+ years of experience in a technical leadership or senior-level engineering role.
• Advanced proficiency in Flutter and Python.
• Demonstrated experience leading software architecture decisions.
• Ability to utilize collaboration tools such as Microsoft Teams.

• Ability to understand and speak English at a level of proficiency allowing the employee to issue, receive, and respond to both safety and operations-related directions in English.

Preferred Qualifications:

• Experience leading distributed or cross-functional engineering teams.

• Familiarity with AI-assisted coding tools such as Cursor, Gemini, Claude, or similar.
• Oil and Gas industry knowledge/experience.
