• Demonstrable hands-on experience in drilling engineering, well design and drilling execution.
• Strong experience developing drilling programmes, casing and cementing designs and well trajectories.
• Practical experience supporting drilling operations and resolving complex operational challenges.
• Valid IWCF or IADC Well Control certification is strongly preferred.
• Membership of a relevant professional engineering body is desirable.
• Strong knowledge of HSE requirements, operational controls, technical procedures and documentation standards.

Technical Expertise

• Drilling engineering and well design.
• Drilling programme development and execution planning.
• Well trajectory and directional drilling planning.
• Casing design and cementing programmes.
• Well control and drilling risk management.
• Drilling performance optimisation and NPT reduction.

• Drilling contractor and service company management.
• Technical assurance and engineering review.
• DWOPs, risk assessments and lessons-learned processes.
• Well integrity and barrier management.
• Drilling data analysis and performance monitoring.
• Technical problem-solving and operational decision support.

What We Value:

• Strong safety mindset and personal accountability.
• Sound technical judgement and structured problem-solving ability.
• Ability to make effective engineering decisions under operational pressure.
• Strong analytical and technical evaluation skills.
• Clear written and verbal communication.
• Effective coordination of drilling contractors, service companies and multidisciplinary teams.
• Strong planning, prioritisation and execution discipline.
• Ability to identify, communicate and escalate operational and technical risks promptly.

• Integrity, professionalism and adherence to approved technical and operational procedures.

HSE & Compliance:

• Comply with applicable company HSE policies, procedures, Permit-to-Work requirements, risk assessments, isolation controls and emergency-response arrangements.
• Incorporate well integrity, well control, process safety and operational risk considerations into drilling programmes and execution plans.
• Ensure drilling designs and operational decisions adequately address identified technical and HSE risks.
• Stop or escalate unsafe work and promptly report incidents, near misses, equipment defects and abnormal operating conditions.
• Participate in relevant safety reviews, pre-job meetings, risk assessments and operational readiness activities.
• Maintain required role-specific medical, safety and professional certifications throughout the assignment.
• Ensure drilling activities comply with approved company standards, applicable regulations and recognised industry practices.
