Requirements
Candidates must have 10+ years of experience in backend systems, distributed infrastructure, or security engineering, with strong modern Ruby on Rails expertise and solid backend architecture experience. Required skills include deployment experience across modern cloud-native stacks (Docker, Kubernetes, Helm, Terraform, multi-cloud), front-end development skills with data visualization and charting frameworks, and strong programming skills in at least one additional language (Python, Go, Rust, or Java). Familiarity with AI/ML security challenges such as adversarial ML, content filtering, and prompt injection is also necessary. Nice-to-have qualifications include contributions to open-source security or AI projects, experience with enterprise integrations (SIEM/SOAR, SOC tools, HIPAA, PCI-DSS, SOC2, ISO, GDPR), and a background in adversarial ML research or compliance-focused security.
Responsibilities
The Staff Software Engineer will build and scale APIs and backend services, focusing on Ruby on Rails, and implement real-time validation, monitoring, and security enforcement for AI-driven workflows. They will evaluate and integrate open source and custom software solutions, and deploy and manage applications in cloud-native environments. Responsibilities also include developing Rails-based features for enterprise integration, compliance reporting, and security workflows, building intuitive front-end components with charting and visualization tools, and ensuring reliability and scalability of services with performance targets. The role involves working with security researchers and product leaders to define the roadmap, and mentoring engineers to contribute to a high-performing technical team.
