Role overview
Based in Southampton, the Marine Accident Investigation Branch (MAIB) is an independent organisation within the Department for Transport. The Branch is responsible for investigating accidents and incidents involving UK vessels anywhere in the world, and any vessels within UK territorial waters, with the aim of improving the safety of life at sea and the avoidance of accidents in future. The Branch is not responsible for apportioning blame or liability, nor does it enforce laws or carry out prosecutions.
The MAIB comprises 34 specialist and administrative staff. Inspectors are divided into four teams each headed by a Principal Inspector.
As a Principal Inspector of Marine Accidents, you will be responsible for supervising a multi-disciplinary team of inspectors carrying out investigations into marine accidents. You will also be a member of the senior management team, contributing to the formulation of policy and the development of the Branch.
Your responsibilities will include, but are not limited to:
- Acting as duty co-ordinator and the Branch’s initial point of contact for out of hours accident notifications within a 4-week cycle; leading and managing a team of specialist accident investigators.
- Deploying to accident sites, at short notice during duty weeks, to manage the more demanding investigations; this could include travel worldwide.
- Directing the progress, conduct, and quality assurance of investigations, the development of recommendations, and overseeing production of the report.
- Dealing with individuals and organisations involved in marine accidents in what can often be stressful situations.
- Representing the Branch at industry fora.
- Contributing to MAIB's wider management strategies.
Great line management is important to us as an organisation, and we will equip and support line managers to develop the skills they need. We aim to empower line managers to create teams where people can flourish and deliver excellent outcomes for the public.
Special Features of the Role
Your commitment to deploy will be managed through a duty system whereby 4 duty teams rotate through a weekly cycle. During your duty week you will need to be available to travel to accident sites at 2 hours’ notice. The following week (standby) you will be at 6 hours’ notice to fill in for or assist the duty team if it is deployed.
For weeks 3 and 4 of the cycle you will be expected to be contactable and available to deploy unless otherwise agreed. Duty rosters are published well in advance to enable you to plan ahead, and flexibility is possible to accommodate important family events and other commitments.

Pre-employment Checking
If your application is successful but you have been dismissed from the Civil Service, your application could be removed at the pre-employment checking stage depending on the nature of the dismissal.
Applicants who are successful at interview will be, as part of pre-employment screening, subject to a check on the Internal Fraud Database (IFD). This check will provide information about employees who have been dismissed for fraud or dishonesty offences. This check also applies to employees who resign or otherwise leave before being dismissed for fraud or dishonesty had their employment continued.
Any applicant’s details held on the IFD will be refused employment. A candidate is not eligible to apply for a role within the Civil Service if the application is made within a 5-year period following a dismissal for carrying out internal fraud against government.
All external applicants and current employees of accredited non-departmental public bodies (NDPBs) will be required to undergo a Social Media Check. A Social Media Check is a review of your publicly available online activity, typically across platforms like LinkedIn, Facebook, X (formerly Twitter), Instagram, and others. The purpose is to identify any public posts or content that could raise concerns for employers, such as:
- Hate speech or discriminatory behaviour
- Threats or acts of violence
- Illegal activity or substance misuse
- Sexually explicit material
- Extremist views or affiliations
Importantly, this check does not involve hacking into your accounts or accessing private messages. It only considers content you have chosen to make public. Employers use this kind of screening to help ensure their workplace remains safe, inclusive, and aligned with company values.
It’s not about judging your personality or lifestyle - it’s about checking for potential red flags that might affect the role or company culture. If you have questions or concerns about the social media check, we would be happy to explain in more detail what’s being looked at and how your data is handled securely and fairly.
Due to the nature of MAIB operations, you will be required to undertake physical activities such as working in disrupted environments, confined spaces and boarding vessels by pilot or shoreside ladders. You will also be exposed to situations, information, and material that may be potentially traumatic.
We therefore advise candidates to consider these requirements before applying. Please note also, that we will require successful candidates to undergo an internal health check assessment before starting in post. Candidates will be given more information on this assessment closer to the time by the Marine Accident Investigation Branch within the Department for Transport.

Please be aware the levels of national security clearance are changing which may impact on the level needed for this role by the time of appointment.
