Role Overview
We are seeking a skilled and dedicated Cloud Engineer to join our London team, to own and optimize our cloud infrastructure and security. This role is crucial for ensuring the efficiency, security, and low latency of our cloud environment. The ideal candidate will have specialized expertise in AWS and experience designing and implementing cloud setups tailored for low latency trading. While the cloud infrastructure is the primary remit of this role, we expect a portion of time to be also dedicated to security: environment hardening, threat monitoring, and contributing to our broader compliance posture.
Key Responsibilities
- Cloud Ownership: Manage and maintain G-20 cloud infrastructure across AWS and Azure, including provisioning, configuration, and ongoing optimisation.
- Networking Optimization: Design and implement scalable, reliable cloud architectures in line with best practices and business requirements.
- Cost Optimization: Monitor cloud environments for cost, performance, and availability, taking proactive steps to improve each.
- Security: Implement and enforce cloud security best practices, including network segmentation, encryption, and access controls and related policies.
- Monitoring: Monitor network reliability and latencies, security alerts and events across endpoint and cloud platforms, triaging and escalating incidents as appropriate.
- Compliance Support: Support compliance efforts relating to frameworks such as Cyber Essentials, ISO 27001, or GDPR.
- Continuous Improvement: Stay current with the evolving cloud and threat landscape and share relevant intelligence with the team.
Education
Bachelor’s or Master’s degree in computer sciences, Computer Science, Engineering, or a related field.
Experience
- Hands-on experience with AWS in a professional context. Azure is a bonus.
- Solid understanding of networking fundamentals (TCP/IP, DNS, firewalls, VPNs).
- A relevant degree, apprenticeship, bootcamp, or self-study background evidenced by cloud certification (e.g. AZ-900, AZ-104, AWS Cloud Practitioner, AWS SysOps, or equivalent).
- Exposure to security monitoring, vulnerability scanning, or network analysis tooling.
- Exposure to cyber security concepts evidenced by certification or practical experience (e.g. CompTIA Security+, CySA+, CEH, or equivalent).
- Scripting ability in Python and Bash, with a desire to develop this further.
- Strong analytical and problem-solving skills, with keen attention to detail.
- Ability to communicate technical concepts clearly to non-technical stakeholders, and to collaborate effectively across functions.
- Highly ethical, trustworthy, and able to operate with discretion and confidentiality.
- Commercially aware and adaptive to the evolving needs of a dynamic financial services business.
- Strong written and verbal communication skills.
Preferred / Desirable Experience
- Experience in designing and implementing cloud solutions for HFT or similar high-performance, low latency environments.
- Familiarity with cloud-native security tooling (e.g. security centres, policy management, or threat detection services).
- Experience with infrastructure-as-code tooling (e.g. Terraform or ARM templates).
- Awareness of common attack vectors (phishing, malware, social engineering) and basic defensive practices.
- Familiarity with AI-assisted security tooling and a genuine interest in how AI is shaping both the threat landscape and defensive capabilities.
- Participation in Capture the Flag (CTF) competitions or other practical security challenges.
