cuspai - Security Engineer
Requirements
• You are motivated by the mission of using AI for planetary-scale impact and understand the high stakes of securing "deep tech" intellectual property. • 3+ years of experience in a DevSecOps, Cloud Security, or Site Reliability Engineering role, preferably within a fast-paced startup or AI-centric company. • Proven experience building and securing CI/CD pipelines (e.g. GitHub Actions, GitLab CI, or Jenkins). • Strong proficiency in Infrastructure as Code (e.g. Terraform, Pulumi) and securing cloud environments (AWS, GCP, or Azure). • Deep understanding of container security and orchestration (Docker, Kubernetes). • Practical knowledge of security frameworks and how to implement them without slowing down development cycles. • Direct experience with AI-specific security tools or defending against LLM-specific vulnerabilities (OWASP Top 10 for LLMs). • Experience with AI Security Posture Management (AI-SPM) tools. • Relevant certifications such as AWS Certified Security, CSEP, or OSCP. • A background or personal interest in materials science, chemistry, or the intersection of AI and physical sciences. • ADDITIONAL CONSIDERATIONS • This role could be based in our Cambridge, London, Amsterdam or Berlin offices, with the expectation of being in the office three days per week. Additionally, there may be regular travel required to other locations for collaboration and project work. • As part of your onboarding, you will be expected to spend at least a few weeks in our Cambridge/London office learning about our platform and getting to know us in person. • Additionally, there may be regular travel required to Europe and other regional and global locations for collaboration and project work.
Responsibilities
• AI-Specific Security & IP Protection • Secure the end-to-end ML lifecycle, implementing defenses against data poisoning and protecting our proprietary model weights from theft. • Design and deploy prompt injection defenses and runtime firewalls to prevent unauthorized manipulation of our LLM interfaces. • Implement AI Security Posture Management (AI-SPM) to monitor and catalog self-hosted models, internal training datasets, and proprietary endpoints. • Cloud Security, CI/CD & Core DevSecOps • Weave automated security “guardrails” directly into our CI/CD workflows, including secret scanning, API exposure checks, and software composition analysis (SCA). • Codify security policies using Infrastructure as Code (IaC), ensuring all cloud resources are automatically compliant with global standards (e.g. GDPR, SOC2). • Manage secrets and vulnerability patching for containerized environments (e.g. Docker, Kubernetes) to ensure our research environment is resilient. • Design strict, least-privilege Identity and Access Management (IAM) controls to isolate sensitive training data and research workloads. • Interdisciplinary Collaboration & Security Culture • Lead incident response efforts by monitoring production logs for anomalies and collaborating with AI Researchers to deploy rapid fixes. • Empower the engineering team to own security by providing tools for local IDE security scanning and pre-commit hooks. • Act as a security educator, cultivating a culture of shared responsibility across the AI, chemistry, and engineering teams. • Partner with researchers, chemists, and engineers to translate security requirements into practical workflows that support rather than slow down scientific work.
Benefits
• A competitive salary: We value and reward impact and growth • Equity in CuspAI: You have a stake in the success of the company • Time off to stay fresh: 28 days holiday (DE, NL, UK) or 21 days holiday (JP, SG, US), in addition to local public holidays • ‘Gold Standard’ parental leave: 26 weeks (primary caregiver) and 12 weeks (secondary caregiver) at full pay - we look after you and your family while we work on the most important materials discovery problems together • Professional development budget: We invest in your career development so you can stay up to date with the latest industry knowledge or add to your skills to increase impact and growth • Solve meaningful problems: See how your work has a direct impact on advancing materials science and solving sustainability and climate-related problems through the creation and application of bleeding-edge SOTA technology and revolutionary techniques • True interdisciplinary teamwork: Be part of a deeply collaborative environment bridging AI research, computational chemistry, and experimental science - work with world-class researchers and engineers who enjoy sharing knowledge and supporting each other • CuspAI is an equal opportunities employer committed to building a diverse and inclusive workplace.
