This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Staff Security Engineer based in the United States.
This role is a high-impact opportunity to shape and secure a rapidly scaling real-time infrastructure platform powering AI-driven applications used globally. You will operate as a hands-on security engineer embedded deeply within the product and infrastructure stack, working across APIs, cloud environments, containers, and distributed systems. Rather than focusing on compliance or policy alone, you will actively design, build, and harden systems in production. The environment is fast-moving and highly technical, requiring strong collaboration with senior engineers and product teams. You will play a critical role in identifying vulnerabilities before they surface, improving secure-by-design practices, and strengthening system resilience at scale. This is a role for someone who thrives at the intersection of offensive and defensive security engineering.
Accountabilities:
You will own end-to-end security across applications, infrastructure, and engineering workflows, ensuring systems are designed and operated with strong security foundations.
- Lead security engineering efforts across cloud infrastructure, services, APIs, and developer tooling, ensuring secure-by-default architecture and implementation.
- Identify, analyze, and mitigate vulnerabilities across codebases, configurations, and distributed systems through proactive engineering-driven approaches.
- Drive secure code reviews, architecture assessments, and threat modeling sessions in collaboration with engineering teams.
- Build automation and internal tooling to detect, prevent, and remediate security issues early in the development lifecycle.
- Strengthen authentication, authorization, and access control systems across internal and external platforms.
- Respond to security incidents, lead investigations, and contribute to post-incident analysis and long-term remediation efforts.
- Partner closely with engineering teams to embed security practices into CI/CD pipelines, deployment workflows, and system design.
Requirements:
You bring deep software engineering experience combined with a strong security mindset and a passion for building resilient systems.
- 6+ years of experience in software engineering with a strong focus on security engineering or secure systems design.
- Proven experience working with cloud environments such as AWS or GCP, containerized systems, and modern CI/CD pipelines.
- Strong understanding of threat modeling, secure coding practices, vulnerability assessment, and incident response.
- Experience leading or contributing to security initiatives across application and infrastructure layers in production environments.
- Hands-on ability to investigate vulnerabilities, respond to incidents, and drive remediation with engineering teams.
- Strong programming skills and ability to work across system layers including APIs, services, and infrastructure components.
- Excellent communication skills with the ability to influence engineers and translate security risks into actionable engineering work.
Benefits:
- Competitive base salary with equity participation
- Comprehensive health, dental, and vision coverage
- Flexible vacation policy supporting work-life balance
- Opportunity to work on cutting-edge real-time and AI-driven infrastructure
- Remote-first environment with collaboration across global engineering teams
- Exposure to open-source contributions and modern distributed systems
- Opportunity to shape security practices in a high-scale, fast-growing engineering organization
