Understanding the MST(MOBILE SUPPORT TECHNICIAN) Ethics and Behaviour Investigator Role at Médecins Sans Frontières-Apply before 17 Mar 2026

Médecins Sans Frontières (MSF) is one of the world’s most respected international humanitarian organizations, providing emergency medical assistance to populations affected by conflict, disasters, and crises. To maintain a safe, ethical, and respectful working environment, MSF employs professionals who ensure staff follow the organization’s strict behavioural standards. One such role is the Mobile Support Technician (MST) Ethics and Behaviour Investigator.

This position plays a critical role in safeguarding communities, patients, and staff by investigating allegations of misconduct across MSF operations worldwide.

What Médecins Sans Frontières Does

Médecins Sans Frontières is an independent medical humanitarian organization that delivers assistance to people in distress regardless of race, religion, political affiliation, or nationality. The organization operates in many countries and relies on a diverse global workforce committed to humanitarian principles.

Within this environment, maintaining ethical conduct is essential. The Ethics and Behaviour Investigator helps ensure that all staff members respect MSF’s behavioural commitments and that any violations are properly addressed.

Purpose of the Ethics and Behaviour Investigator Role

The MST Ethics and Behaviour Investigator is responsible for conducting administrative investigations into alleged misconduct involving MSF staff. These investigations ensure that reports of abuse or unethical behaviour are handled professionally, confidentially, and fairly.

The role strengthens MSF’s safeguarding systems by ensuring that complaints are investigated using proper procedures and survivor-centred approaches.

Investigators work closely with the Ethics and Behaviour Unit leadership to promote accountability and reinforce a respectful working culture across MSF missions.

Key Responsibilities of the Position

The investigator carries out a range of responsibilities related to misconduct investigations and safeguarding processes.

Core duties include:

• Conducting investigations into alleged violations of MSF behavioural policies
• Gathering and analysing evidence through interviews and document reviews
• Interviewing victims, witnesses, and accused individuals
• Preparing detailed investigation reports with evidence-based findings
• Maintaining confidential case management records
• Ensuring investigation procedures follow MSF standards and due process
• Safeguarding sensitive information in line with data protection policies

These investigations may be conducted remotely or through field visits to MSF country programmes.

Types of Misconduct Cases Investigated

The Ethics and Behaviour Investigator deals with a wide range of sensitive cases involving staff conduct. Investigations may involve allegations such as:

• Sexual exploitation and abuse (SEAH)
• Sexual harassment
• Discrimination or racism
• Workplace bullying
• Aggression or threats
• Abuse of power by supervisors or managers
• Other violations of MSF behavioural commitments

Handling these cases requires strong professionalism, empathy, and discretion, as investigators often interact with vulnerable individuals or survivors of abuse.

Work Environment and Travel Requirements

This position is typically home-based, but it involves significant travel to MSF field missions. Investigators may spend around 50 percent of their working time in the field, supporting investigations in different countries where MSF operates.

Field assignments can last four to eight weeks at a time and may involve working in challenging humanitarian contexts. Investigators must therefore be adaptable, culturally sensitive, and capable of working within diverse international teams.

The role also requires the ability to operate independently while coordinating with multidisciplinary safeguarding and ethics teams.

Skills and Qualifications Required

Candidates applying for this role generally need a strong academic and professional background related to human rights, social sciences, or investigations.

Typical requirements include:

Educational background:

• Degree in psychology, sociology, social work, law, human rights, human resources, or a related field

Professional experience and skills:

• Experience conducting professional investigations
• Strong analytical and interviewing skills
• Ability to write clear, high-quality investigative reports
• Knowledge of safeguarding and confidentiality standards

Languages:

• Fluency in English and French is mandatory
• Spanish or Arabic can be an additional advantage

Specialized training in trauma-informed interviewing, safeguarding investigations, or handling cases involving children is also considered valuable.

Personal Qualities Needed for Success

Working as an Ethics and Behaviour Investigator requires more than technical knowledge. Because the role deals with highly sensitive situations, investigators must demonstrate specific personal qualities.

These include:

• Emotional resilience when dealing with difficult cases
• Strong ethical judgement
• Excellent communication and listening skills
• Cultural awareness and respect for diversity
• Ability to remain neutral and objective during investigations

These qualities help ensure investigations are fair, respectful, and supportive of survivors.

Contract Details and Career Opportunities

The MST Ethics and Behaviour Investigator position is typically offered as a full-time role with a one-year contract, with the possibility of extension depending on operational needs.

Working in this role provides professionals with an opportunity to contribute directly to ethical accountability within a major humanitarian organization while gaining international field experience.

It is particularly suitable for professionals with backgrounds in safeguarding, human rights investigations, compliance, or humanitarian protection.

Final Thoughts

The Ethics and Behaviour Investigator role at Médecins Sans Frontières is essential to maintaining trust, integrity, and safety within humanitarian operations. By conducting professional investigations and supporting survivor-centred processes, investigators help ensure that MSF’s mission is carried out with respect, accountability, and dignity for all.

For professionals committed to safeguarding human rights and ethical conduct in humanitarian work, this role offers a meaningful and impactful career path.
