What you’ll be doing
As an Investigation Support Officer within the Independent Complaints and Grievance Scheme (ICGS), you’ll play a vital role in supporting independent investigations into allegations of bullying, harassment, and sexual misconduct across the parliamentary community. Working alongside externally appointed investigators, you’ll help gather, analyse and present evidence, ensuring investigations are conducted thoroughly, sensitively, and in line with established policies, procedures, and data protection requirements.
This is a varied and high-profile role where you’ll manage multiple investigations simultaneously, engaging with a wide range of stakeholders across both Houses of Parliament and associated bodies. You’ll apply your investigative expertise to support evidence-led decision making, identify further lines of enquiry, and contribute to the continuous improvement of the Scheme through project work, guidance development, and the promotion of best practice.
Key Responsibilities
- Plan, conduct and support complex investigative interviews, prepare interview plans, review transcripts, and ensure interview records are accurate and agreed.
- Gather, collate, and analyse evidence including emails, text messages, CCTV footage, and witness accounts, identifying relevant information and potential further lines of enquiry.
- Prepare high-quality investigation materials, evidence bundles, and reports, ensuring compliance with GDPR, confidentiality requirements, and evidential standards.
- Build effective relationships with a diverse range of stakeholders, providing a professional, compassionate, and impartial service throughout sensitive investigations.
- Support the continuous improvement of the ICGS by contributing specialist investigative expertise, supporting projects, maintaining accurate case records, and helping develop guidance and best practice.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
