Job description

Rimkus has an established and growing collision investigation practice in the UK and across the EMEA region, and we aim to set the standard for the sector. We are looking for people who are, or have the potential to become, industry leaders. We are looking to appoint at least one Associate Director to report to our Director - Forensic Collision Investigation and work together to lead our growth across the civil and criminal sectors. This is a senior, fee-earning expert role with genuine influence. You will have experience of carrying a caseload of complex and high-value matters, be able to lead the growth and quality of your sector, and help shape the methods, tools and training that our consultants learn from.

Opportunity: Rimkus is a global forensic engineering and expert consulting firm, and our UK collision investigation practice is growing fast. We have built a strong book of business and are now growing our collision investigation team to be ready for the future, one where our skills with vehicle and road user data together within-vehicle video and CCTV, align with more traditional engineering and human factors approaches to provide comprehensive support to our clients. You will join a wider multidisciplinary team with extensive expert witness and research experience. Our experts give evidence in the civil and criminal courts, publish in their fields, and are determined to push the discipline forward rather than simply keep pace with it. Growth on this scale creates career progression that established firms struggle to match. As the practice expands, so do the opportunities to lead specialisms and people. We recruit from two talent pipelines: experienced police forensic collision investigators and engineers with a background in vehicle dynamics and crash reconstruction. We want both, because the strongest collision reconstruction teams draw on both.

Leading Criminal or Civil Investigations In civil matters, insurers, solicitors, fleet operators, and corporate legal teams instruct us on disputed liability, fatal and catastrophic injury claims, suspected fraud, and cross‑border cases. In criminal proceedings, we support prosecution and defence teams in cases where the reconstruction evidence is key. Both need evidence that is independent, objective, transparent and robust under cross‑examination. As Associate Director, you will take the lead on one of these sectors, working collaboratively with the Director and the wider team. We own its client relationships, quality and growth together, and you will help make sure every report it produces meets that standard. Our technical lead portfolios Alongside these leadership roles, we are building four technical lead portfolios across the team:

• Technical Lead, Vehicle Data, ADAS and Telematics
• Technical Lead, e-Mobility ,and Connected & Autonomous Vehicles
• Technical Lead, Forensic Video Analysis
• Technical Lead, Commercial Vehicle Investigation

Each technical lead will own the methods, validation and training in their area. Associate Directors with the right depth of expertise may also hold one of these portfolios, so tell us where your specialism lies. This is a chance to build something rather than inherit it. You will help decide the best methods to use, how we validate them, and how we use them to support our clients. You will also work alongside colleagues across Rimkus's wider engineering and scientific disciplines, including human factors, biomechanics and injury causation, toxicology, and others, which brings complex, multidisciplinary cases to our door.

Key responsibilities

• Work collaboratively with the Director - Forensic Collision Investigation to lead the practice's Criminal or Civil Investigations work, sharing ownership of client relationships, case allocation, quality and the growth of that sector.
• Lead complex and high-value instructions, including fatal and catastrophic injury collisions, HGV, bus and fleet matters, and cases that rely on multiple digital data sources.
• Attend collision scenes and vehicle examinations when evidence is time‑critical, including outside normal working hours.
• Prepare expert reports compliant with CPR Part 35 and Criminal Procedure Rules Part 19, attend joint expert discussions, and give oral evidence in civil and criminal courts and at inquests.
• Peer review reports before issue, and uphold the high technical standards set with the practice's technical leads.
• Where it matches your expertise, take ownership of a technical lead portfolio, developing and validating the team's methods in that area.
• Mentor and train consultants, and support their development into independent expert witnesses.
• Keep the practice ahead of change, including ADAS, automated vehicles, EDR regulation and e‑mobility.
• Win and grow work in your sector through client relationships, proposals, client CPD seminars, conference presentations, industry‑leading research, and published articles.
