The Contentsquare Security team is looking for an application security engineer (Appsec) who can work closely with the development team, product managers and diverse third-party groups (including bug bounty hunters).
Contentsquare provides a globally leading SaaS service and commits to the highest security standards for its customers. We are ISO 27001 and ISO 27701 certified and maintain robust security initiatives (SOC 2 Type 2 report, private bug bounty program, SIEM, advanced security awareness, etc.).
As an Application Security Engineer, you'll help secure Contentsquare's applications throughout their lifecycle, from identifying and validating vulnerabilities to understanding their root cause, driving remediation with Engineering teams, and improving how security issues are detected and prevented.
You'll bring a strong offensive security mindset and hands-on experience testing web applications, APIs and services, while working closely with developers to translate findings into practical, scalable security improvements. You'll have end-to-end ownership of application security issues, from detection and exploitation through remediation and validation.
Conduct continuous, automated security audits of our global SaaS applications to identify misconfigurations and ensure strict adherence to industry-standard security benchmarks and internal best practices.
Serve as a strategic security consultant to product and engineering teams, facilitating complex threat modeling sessions and AppSec reviews during the design phase to proactively mitigate risks.
Perform deep-dive, security-focused code reviews and mentor developers on secure coding patterns to minimize the introduction of high-impact vulnerabilities.
Architect and manage the end-to-end vulnerability lifecycle, developing sophisticated automation for the triage, reporting, and remediation tracking of security flaws across cloud infrastructure and application layers.
Orchestrate and optimize AI-driven security workflows, leveraging LLMs and autonomous agents to conduct scaleable, proactive vulnerability discovery and validation within our CI/CD pipelines.
Lead "Shift-Left" initiatives by integrating security checkpoints into the automation stack, developing custom security-as-code tools that empower developers to own security outcomes.
Oversee the strategic direction of our private and public bug-bounty programs, ensuring high-quality engagement with the researcher community and rapid internal response to critical findings.
Coordinate specialized external penetration testing engagements and customer-driven security assessments, acting as the primary technical point of contact for complex security inquiries.
Drive the technical response to application-level security incidents, conducting root-cause analysis to prevent recurrence and enhance our defensive posture.
3+ years of professional experience in Application Security Operations within a high-growth SaaS or cloud-native environment.
Advanced proficiency in securing modern technical stacks, with specific expertise in NestJS, Vue.js, and Angular frameworks.
Hands-on experience with enterprise security tooling, including Snyk, Datadog ASM/AppSec (WAF), Google SecOps, and Crowdstrike.
Deep architectural understanding of AWS and Azure environments, including Kubernetes/Docker container security and Infrastructure as Code (Terraform).
Demonstrated ability to apply AI and LLM technologies to automate security tasks, such as automated vulnerability validation or code analysis at scale.
Expertise in scripting and development (Python, Node.js, Shell) to build custom security tooling and integrations.
Comprehensive knowledge of web protocols, OWASP Top 10, and advanced threat frameworks (MITRE ATT&CK, NIST CSF).
Proven track record in ethical hacking, CTF competitions, or bug bounty hunting, showcasing a high level of technical tenacity and analytical rigor.
Exceptional cross-functional collaboration skills, with the ability to articulate complex security risks to both technical and non-technical stakeholders.
