Infrastructure Engineer - Security

About Slash

Slash is building the future of business banking, one industry at a time. We combine the reliability of traditional banking with industry‑specific features that make businesses more efficient, more competitive, and more profitable.

We are looking for an Infrastructure, Security Engineer to own security across our platform, from cloud infrastructure to application code. You will be our first dedicated security hire and will shape how we think about and implement security at Slash.

• Own Slash’s security posture end‑to‑end — from threat modeling to incident response
• Harden our cloud infrastructure (AWS, Kubernetes, Terraform) with secure configurations and least‑privilege access controls
• Implement and maintain security tooling: vulnerability scanning, SIEM, intrusion detection, secrets management
• Lead security reviews of code, architecture, and third‑party integrations
• Own and execute against PCI‑DSS, SOC 2, and other compliance frameworks — not just audits, but actually building the controls
• Build automated security guardrails into our CI/CD pipeline
• Monitor, investigate, and respond to security events; run incident response when needed
• Partner with engineering to fix vulnerabilities and ship secure code — you’ll write patches, not just tickets
• Define and iterate on our security roadmap as we scale

• Has 4+ years of experience in security engineering, with hands‑on infrastructure experience (AWS, Kubernetes, Linux)
• Can read code, write code, and isn’t afraid to ship fixes in a production environment
• Has experience with security tooling: SIEM, vulnerability scanners, WAFs, secrets management, etc.
• Understands modern attack vectors and how to defend against them in cloud‑native environments
• Has worked with compliance frameworks (PCI‑DSS, SOC 2) and knows how to implement controls that actually work
• Is comfortable with ambiguity — you’ll be building the security function from the ground up
• Communicates well and can work cross‑functionally with engineers who aren’t security experts
• Gets things done. We need someone who ships, not someone who just writes reports.

• Opportunity for high growth, Series B, Fintech start‑up
• High autonomy + ownership culture
• Comprehensive health + benefits plan
• Working out of our new San Francisco office space
• Unlimited Vacation
