About the AI Security Institute
The AI Security Institute is the world's largest and best‑funded team dedicated to understanding advanced AI risks and translating that knowledge into action. We work with frontier developers and governments globally, with direct lines to No. 10 in the UK government.
About the Chem Bio team
AISI's Chem Bio (CB) team conducts technical research to assess evolving AI capabilities related to science R&D and CB misuse, and evaluates the effectiveness of technical safeguards that might mitigate risks arising from those capabilities. The goal of our research is to inform critical decisions on security, opportunities, policy, and risk mitigation made by governments and AI developers.
Role Responsibilities
- Join a small, talent‑driven, multidisciplinary team evaluating state‑of‑the‑art AI models for engineering biology.
 
- Setup and deploy leading biological models and evaluate these models in line with AISI's research objectives.
 
- Design and deliver evaluations and experiments to assess capabilities of AI models in fields such as protein design, structure prediction and biological foundation models.
 
- Lead on research projects to understand the feasibility and effectiveness of potential technical safeguards for biological models.
 
- Investigate critical research questions at the intersection of AI and biosecurity, contributing to a technical evidence base used to advise and inform wider cross‑Government efforts in this space.
 
Requirements
- Background in machine learning, having worked directly on training, tuning or evaluating machine learning models using PyTorch or similar.
 
- Experience working on leading biological AI models, such as protein design models, structure prediction or scientific foundation models.
 
- Experience writing production‑level Python code that is scalable, robust and easy to maintain, ideally in a team.
 
- Sufficient knowledge of biology and machine learning concepts to understand and stay at the frontier of AI × Bio research literature.
 
- A sense of mission, urgency, and responsibility for success; demonstrated ability to solve challenging problems, implement solutions efficiently and acquire any missing knowledge necessary to get the job done. Motivated to conduct technical research with an emphasis on direct policy impact.
 
- Strong communication skills, with the ability to work effectively in a dynamic, multidisciplinary team environment.
 
Important: this is a reserved post. We can only consider applications from UK nationals (including dual nationals who hold British citizenship).
Appointment is conditional on successfully completing UK Government SC clearance. Prior clearance is not required – we will sponsor and support you. You should normally have been resident in the UK for the past 5 years. You may also be required to undergo Developed Vetting (DV). DV typically requires a longer period of UK residency (around 10 years). Employment is conditional on obtaining and maintaining the required clearance(s).

Salary
Annual salary is benchmarked to role scope and relevant experience. Most offers land between £65,000 and £145,000 (base plus technical allowance), with 28.97% employer pension and other benefits on top.
This role sits outside of the DDaT pay framework given the scope of this role requires in‑depth technical expertise in frontier AI safety, robustness and advanced AI architectures.
The full range of salaries are as follows:
- Level 3: £65,000–£75,000 (Base £35,720 + Technical Allowance £29,280–£39,280)
 
- Level 4: £85,000–£95,000 (Base £42,495 + Technical Allowance £42,505–£52,505)
 
- Level 5: £105,000–£115,000 (Base £55,805 + Technical Allowance £49,195–£59,195)
 
- Level 6: £125,000–£135,000 (Base £68,770 + Technical Allowance £56,230–£66,230)
 
- Level 7: £145,000 (Base £68,770 + Technical Allowance £76,230)
