Senior Security Engineer

We are seeking an experienced Senior Security Engineer to join our dynamic Security Team. In this key role, you will be a key contributor to Funding Circle's cloud and application security posture. You will leverage your deep expertise in AWS security, secure software development lifecycle (SSDLC) practices, and CI/CD security to implement and champion robust security solutions. You will act as a subject matter expert and mentor, collaborating closely with engineering and product teams to embed security seamlessly into our cloud infrastructure and development processes, ensuring the protection of our platform and customer data in a fast-paced FinTech environment.

Who are we?

We're Funding Circle. We back small businesses to succeed.

At Funding Circle, we believe the world needs small businesses. That's why we've made it our mission to help them get the finance they need to grow.

With more than a decade of expertise under our belt, we've built a game-changer of a platform with cutting-edge data and technology that's reshaping the landscape of SME lending. Say goodbye to lengthy applications and hello to lightning-fast decisions! In just minutes, SMEs across the UK can get a decision, giving them access to competitive funding in a flash.

We know that good business is about good people. So we pride ourselves on providing meaningful, human support as well as fast, hassle free processes to deliver an unbeatable customer experience.

The role

  1. Define, champion, and embed secure software development lifecycle (SSDLC) practices and secure coding standards across engineering teams through collaboration, training, and tooling.
  2. Architect, build, and maintain automated security controls, tooling, and "security rails" within CI/CD pipelines to ensure secure and efficient deployments.
  3. Collaborate closely with Cloud Platform Engineers, DevX and Product Engineering to ensure security requirements are integrated into system designs and technology choices from the outset.
  4. Perform threat modelling exercises for cloud-native applications, microservices, and infrastructure components.
  5. Manage internal and external penetration testing engagements for Funding Circle applications, services, and cloud infrastructure.
  6. Oversee and enhance vulnerability management processes, focusing on strategic remediation, root cause analysis, and preventative measures.
  7. Contribute to drive implementation of security automation across cloud infrastructure configuration, vulnerability management, and compliance monitoring.
  8. Design, implement, and support the adoption of robust security architectures, controls, and best practices within our AWS cloud environment.
  9. Act as a subject matter expert on cloud security (AWS), DevSecOps, and application security, providing guidance and mentorship to other engineers.
  10. Contribute to the incident response planning for complex cloud and application security events.
  11. Proactively monitor the threat landscape, evaluate emerging cloud security risks and trends, and translate them into actionable security improvements.

What we're looking for

  1. Significant (3+ years) hands-on experience in Information Security, with a demonstrable deep focus on AWS cloud security and application/product security.
  2. Deep, demonstrable expertise in designing, implementing, securing, and managing a wide range of AWS security services.
  3. Proven, hands-on experience architecting, building, and integrating security tooling (SAST, DAST, SCA, secrets management, IAST) and automated security controls within CI/CD pipelines (e.g., GitLab CI, Jenkins, GitHub Actions).
  4. Strong track record of defining, implementing, measuring, and supporting the adoption of secure software development lifecycle (SSDLC) practices and secure coding standards within engineering organizations.
  5. Strong understanding of web application security vulnerabilities (OWASP Top 10 and beyond), attack vectors, and mitigation techniques.
  6. Significant experience securing Infrastructure as Code (IaC), particularly Terraform, and implementing relevant security checks.
  7. Solid experience with container security and securing container orchestration platforms (Kubernetes/EKS).
  8. Proven ability contributing significantly to vulnerability management programs, including advanced triaging, root cause analysis, risk assessment, and strategic remediation planning.
  9. Strong communication and influencing skills, with the ability to articulate complex security concepts clearly to technical audiences.
  10. Strong knowledge of relevant security frameworks and standards (e.g., NIST CSF, CIS Benchmarks, OWASP ASVS).
  11. Exposure and knowledge of the MITRE ATT&CK framework.
  12. Experience effectively coordinating external penetration testing engagements and managing remediation efforts.

Nice to have

  1. Relevant advanced security certifications (e.g., AWS Certified Security - Specialty, CISSP, CCSP, OSCP/OSWE).
  2. Experience with specific security platforms/tools (e.g., Wiz, Snyk, Checkmarx, Veracode).
  3. Proficiency in security automation using scripting languages (e.g., Python).
  4. Experience working in FinTech or other highly regulated environments.
  5. Experience with mobile application security principles and testing.

At Funding Circle we are committed to building diverse teams so please apply even if your past experience doesn't align perfectly with the requirements.

Quantum-Enhanced AI in Cyber Security: Guarding the Digital Frontier

The cyber security landscape has evolved dramatically over the past decade. Long gone are the days when businesses primarily worried about simplistic phishing or basic website defacements. Today’s threats include nation-state attacks, sophisticated ransomware, AI-generated phishing campaigns, and a wide array of stealthy intrusion methods. Organisations must defend vast digital ecosystems that include cloud infrastructure, IoT devices, and critical operational technology—any of which can become high-value targets for malicious actors. Amid these escalating challenges, a new technological wave is emerging: quantum computing. Although still in its infancy, quantum computing promises capabilities that could surpass even the most advanced classical supercomputers for specific tasks. Simultaneously, in the world of Artificial Intelligence (AI)—where data volumes and model complexity are exploding—quantum’s parallelism could significantly boost analysis, training, and decision-making. What unfolds when quantum computing and AI converge in the realm of cyber security? On one hand, quantum technologies could introduce stronger encryption and faster threat detection. On the other, adversaries armed with quantum power might break today’s cryptographic protocols or develop more potent attacks at unimaginable speeds. This article explores the phenomenon of quantum-enhanced AI for cyber security: the possibilities it unlocks, the challenges it poses, and the reasons it could reshape both defensive and offensive operations in the digital world.
