Senior Security Engineer

The  Team:

Our Global information security organization is responsible for security and trust. We think security-offensively and defensively. We continuously monitor our global security posture and are always adapting to the ever-changing threat landscape. The security engineering team is looking for talented subject matter experts in application, platform and offensive security.

The Role:

Celonis is looking for talented Security Engineers to join the Security Engineering Team. You will work with our platform and product engineers, to continually review and validate the security of our security posture at Celonis. Some of the responsibilities include architecture guidance for common vulnerabilities, such as Remote Code Execution (RCE), Privilege Escalation, misconfiguration, and other OWASP top 10 vulnerabilities (SQL injection, XSS, broken access control, etc).

The work you’ll do:

• You will conduct threat modeling, architecture review, security code review, security assessment, penetration testing (web application, native application, web services, cloud-based services, and infrastructure assessments).
• Conducting security architecture reviews of the application stack, including applications built on cloud and emerging technologies
• Reviewing source code for potential security issues
• Writing security test cases to check for vulnerabilities or broken/missing security controls
• Providing specific risk assessment and remediation guidelines for developers and business owners
• Researching the latest security best practices, trends, threats and vulnerabilities, and technology frameworks

• You will be asked to perform cloud infrastructure review from a security perspective; the primary focus will be on AWS and many of its common service components such as S3, IAM, EC2, VPC.
• Perform in-depth security review of new features. This includes identifying security vulnerabilities (OWASP top ten, common issues in NVD, RCE), reviewing code in Java or C++, verifying security posture through pen-test (using manual/automated techniques with tools like Kali Linux, Burp suite, Checkmarx, WebInspect).
• You will partner with engineering and operation teams to integrate mitigation controls into continuous integration, delivery and deployment processes.
• Work on essential areas to develop security baseline for cloud, container, and application and integrate it into the CI/CD pipeline.

• Implement security architecture, methods, and controls required to meet security, compliance, and audit requirements (NIST controls, SOC2).

The qualifications you’ll need:

• Bachelor's degree in Computer Science, Information Science, Cyber Security, Computer or Electrical Engineering (or similar field), and 2+ years in security.
• Experience in penetration testing in different environments, including assessing security posture of web application, native application, distributed systems, and cloud infrastructure such as AWS.
• Understanding of software security architecture and design, threat modeling, security code review, SDLC, and best practices and mitigations for application security.
• Hands-on security experience working with AWS and common service components within AWS. Identify security gaps in the design and configuration issues in individual components.
• In-depth knowledge of network-based, system level, and application layer attacks and mitigation methods.
• Experience with a broad range of hyperscalers AWS,Azure and GCP
• Knowledge of technology and security topics including network and application security (OWASP), infrastructure hardening, security baselines, web server, and database security.
• Expertise in cloud automation tools such as Terraform, CloudFormation, Ansible, etc.
• Development experience in programming languages such as Java, JavaScript, Python, or Go.
