JOB TITLE: OCC Engineer

REPORTS TO: Senior Performance Manager

JOB LOCATION: Operations Control Centre, Stockwell

SUMMARY:
The OCC Engineer is a critical technical specialist within the Go-Ahead London Operations Control
Centre. Working side-by-side with iBus Controllers and operational teams, the OCC Engineer leads
the technical response to on-road mechanical issues, ensuring incidents are assessed quickly, risks
are managed effectively, and services are returned to normal safely and efficiently.
The role requires strong diagnostic capability, excellent communication, and the ability to stay
calm and solution-focused in a fast-paced, high-pressure environment. OCC Engineers act as the
engineering subject-matter experts for the Control Centre, supporting decision-making, coaching
controllers on technical best practice, and liaising with garages, drivers and roadside teams.

PRINCIPAL RESPONSIBILITIES AND AUTHORITIES:
Incident Management & Technical Assessment
• Provide immediate technical assessment of on-road breakdowns, faults and vehicle
incidents using available data and systems.
• Utilise Geotab and Tranzaura to assess defect severity, vehicle condition, driver reports and
likely next steps, ensuring a safe and timely response.
• Determine the most effective response, remote reset, driver instruction, dispatching an
engineer, recovery, or allocating a replacement vehicle.
• Ensure risks are identified early and that safety remains the first priority in all decision making.
Control Centre Support & Collaboration
• Work closely with iBus Controllers to manage mechanical incidents, offering clear technical
advice and supporting prioritisation of resources.
• Act as the engineering expert within the Control Centre, helping controllers understand
vehicle symptoms, common faults and the operational impact of mechanical issues.
• Communicate clearly and professionally with drivers, offering concise instructions and
reassurance.
• Liaise with garage engineering teams and roadside engineers to coordinate responses and
ensure smooth handover of information.
Coaching, Training & Best Practice
• Coach controllers on best practice when managing mechanical defects, including:

• Recognising early-warning signs

• Communicating effectively with drivers
• Understanding safety-critical vs non-critical defects
• Determining appropriate escalation routes
• Support continuous improvement by identifying recurring faults, trends or training needs
across the operation.
• Share expert knowledge across all Go-Ahead London bus types, systems and common defect
patterns.
Quality, Compliance & Reporting
• Ensure all incident information, engineering data and system updates are recorded
accurately and in line with TfL and company requirements.
• Highlight repeat defects, vehicle trends or safety concerns to Engineering Management.
• Contribute to post-incident reviews, providing technical insight and recommendations to
improve reliability and reduce on-road failures.
Communication & Behaviour
• Maintain a calm, professional and composed demeanour during high-pressure situations.
• Communicate clearly and confidently with drivers, controllers, engineers and stakeholders
at all levels.
• Build strong working relationships across Engineering, Operations, Roadside Teams and the
Control Centre.
General Duties
• Stay current with emerging vehicle technologies, diagnostic tools and fleet changes.
• Carry out any other duties reasonably requested by the Operations Control Centre Manager
or Engineering leadership.
• Participate in relevant training and development to maintain technical excellence.
SKILLS, EXPERIENCE, CONDITIONS SPECIFICATION:
Essential
• Extensive engineering knowledge across all bus types in the Go-Ahead London fleet
(including hybrid and electric).
• Strong diagnostic skills and ability to interpret technical data remotely.
• Experience with Geotab, Tranzaura or similar telematics/inspection platforms.
• Excellent verbal communication and the ability to remain calm under pressure.
• Ability to work collaboratively with controllers and operations colleagues in a fast-paced
environment.
• NVQ Level 3, City & Guilds Level 3, or equivalent engineering qualification.
• Flexibility to work shifts, including nights, weekends and Bank Holidays in line with OCC
requirements.
Desirable:
• Experience working within a Control Centre, command environment or emergency response
setting.
• PCV Licence (or willingness to obtain within 12 months).
SAFETY AND COMPANY RESPONSIBILITIES:
• Adhere to all Go-Ahead London safety policies, procedures and values.
• Maintain responsibility for personal safety and that of colleagues, reporting any accidents,
near misses or unsafe conditions immediately.
• Follow all Health & Safety requirements, including safe systems of work, risk assessments
and PPE guidance as appropriate to the role
