As a Senior Security Engineer youll be a key technical contributor and subjectmatter expert working on projects that materially reduce risk and strengthen Sifts security posture.

Role:
In this role you will design implement and operate security controls and tooling across Sifts stack. Youll work closely with Engineers SREs IT and Legal/Compliance to secure our systems endtoendfrom application code and CI/CD pipelines to cloud infrastructure and identity. You will also help define our standards mentor other engineers on secure practices and contribute directly to audits and compliance efforts.

What youll do:

• Design and implement security controls and tooling across Sifts infrastructure and applications (e.g. IAM policies network controls secrets management endpoint protections container and workload security).

• Embed with product and platform teams to perform security design reviews threat modeling and code or configuration reviews for new features and services.

• Improve the secure SDLC by integrating AI-powered scanning tools security scanning (SAST/DAST dependency and container scanning) into CI/CD and by developing guardrails templates and best practices for engineers.

• Own or coown vulnerability management workflows from discovery and triage through remediation including defining SLAs coordinating with service owners and tracking closure.

• Develop automation (scripts services integrations) to detect misconfigurations anomalous activity or policy violations and to reduce manual operational work for the security team.

• Participate in security incident response (oncall rotation or escalation) including investigation containment root cause analysis and longterm fixes.

• Contribute to security documentation and standards ensuring we have clear actionable guidance for engineers on topics like authentication authorization data encryption and key management.

• Support audits and assessments (e.g. SOC 2 customer security questionnaires) by providing technical details and evidence of control design and effectiveness.

• Mentor other engineers on secure design and implementation practices through pairing reviews training sessions and written guidance.

What will make you a strong fit:

• 5 years of experience in security engineering infrastructure engineering or application security ideally in a B2B SaaS or cloudnative environment.

• Handson experience with at least one major public cloud platform (e.g. GCP AWS) including IAM networking logging/monitoring and security services.

• Strong proficiency in at least one programming or scripting language (e.g. Python Go Java or similar) and experience using code to automate security controls or detection.

• Direct experience with AI/LLM-specific security risks (prompt injection model supply chain etc.)

• Demonstrated knowledge of secure application and system design including topics like authentication/authorization encryption in transit and at rest leastprivilege access and secrets management.

• Experience with security tooling such as vulnerability scanners SAST/DAST tools SIEM/centralized logging endpoint protection or cloud security posture management.

• Solid understanding of common vulnerabilities and attack patterns (e.g. OWASP Top 10 misconfigurations supplychain risks) and how to mitigate them in practice.

• Ability to work crossfunctionally with engineering IT and compliance/legal teams and to translate security requirements into practical implementation details.

• Clear written and verbal communication skills including the ability to document designs and decisions and to educate others on security best practices.

• A collaborative pragmatic approach: youre comfortable making riskbased decisions proposing options and supporting teams in implementing secure scalable solutions.
