Do you want to tackle the biggest questions in finance with near infinite compute power at your fingertips?

This role is based in our new Soho Place office – opened in 2023 - in the heart of Central London and home to our Research Lab.

The role

The Security Threat Specialist, working in collaboration with the business, will be responsible for both proactive and targeted threat and vulnerability identification for cyber and insider threats across the organisation. You will translate these findings into tactical fixes and help advise on the strategic remediation.

Key responsibilities of the role include:

  • Threat Hunting and Analysis
    • Performing in-depth reviews of systems and processes to determine weaknesses and control gaps in securing against attack chains to our most valuable assets
    • Authoring technical security documentation and threat modelling at all security levels (high level logical down to low level components)
    • Working with the Cyber Security & Incident Response Team and Vulnerability Assessment Team to validate findings, and alongside the business to coordinate remediation
    • Developing and delivering training and awareness to improve the business’s ability to self-identify security weaknesses
    • Automating threat hunting activities to deliver continuous confidence in security of attack chains
  • Security Design, Architecture, and Risk Management
    • Providing detailed technical design advice on relevant projects, including for the long-term where required
    • Authoring technical security documentation, including policies, standards and technical implementation guidance
    • Making technical security recommendations to improve the security of new or existing applications, services, infrastructure and processes
    • Assisting developers and systems administrators in designing and evaluating secure solutions
    • Identifying key points that will require auditing to ensure future compliance with internal policy/standards or, where relevant, any indicators of potential compromise
    • Supporting the business in making appropriate risk management decisions
    • Driving improvements that balance security vs productivity by architecting secure-by-design systems and processes that are integrated with a good user experience

Who are we looking for?

The ideal candidate will be a capable and hands-on contributor. You must be both experienced and enthusiastic about your area of expertise and have a track record of excellence.

The ideal candidate will have the following skills and experience:

  • Demonstrable expertise in one of the major security specialist areas, such as penetration testing, incident response, endpoint security, network security, malware analysis or identity access management

  • Practical experience of threat modelling and risk assessment of applications, services and infrastructure
  • Technical experience reviewing engineering designs and implementations, including code reviews, for example, high level programming languages, yaml and json
  • Excellent knowledge and a passion for information and technical security, as well as its technologies
  • An interest in and desire for focusing on team and personnel-related matters as opposed to focusing solely on isolated challenges
  • Sufficiently confident about security to make quick but justified commercial-based decisions

Behavioural competencies

  • Collaboration: Works well with cross-functional teams, fostering a collaborative and supportive environment
  • Initiative: Proactively identifies opportunities for improvement and takes the necessary action to implement changes
  • Problem Solving: Capable of assessing complex security issues and devising effective response strategies
  • Communication: Excellent communication skills, both upwards and downwards, through a variety of media, and with the ability to convey complex information to both technical and non-technical stakeholders
