Security Engineer, Enterprise

Persona builds identity verification infrastructure where security isn't a layer we add later, it's core to everything we ship. When security fails at most companies, systems go down. At an identity verification company, real people's identities are compromised. This is an enterprise security role embedded in a generalist security team. You'll work alongside experienced security engineers to defend Persona's people, devices, and systems against evolving threats - and build the tooling and automation that lets us do it at scale.

Responsibilities

Develop, tune, and operate endpoint detection and response (EDR) rules and tooling across our macOS environment; Partner with TechOps to implement security best practices across SaaS and endpoint environments, including 2FA enforcement, automated device encryption, and DLP. You will develop and deploy these controls - not ask other teams to do so for you; Build tools and automation to scale security controls and monitoring without scaling headcount; Harden corporate infrastructure and SaaS applications against attack; Translate endpoint and SaaS telemetry into actionable mitigations and control recommendations; Build and operate insider threat detection and response programs

Requirements

3+ years of experience in IT security, corporate/enterprise security, or a related technical role. We'll flex on years of experience and specific tool background for candidates who demonstrate strong fundamentals, high aptitude, and a track record of figuring things out fast; Hands-on experience with macOS endpoints, MDM platforms, and EDR tooling; Experience with endpoint hardening. You’ve hardened endpoints, not written requirements asking someone else to do it; Experience with DLP concepts and insider threat scenarios; Experience with email security fundamentals and social engineering defense; Ability to write scripts and automate workflows in Python, Ruby, Bash, or similar; comfortable with SQL; Communicates clearly about security topics with non-technical stakeholders; Experience in a high-growth startup or other fast-moving, resource-constrained environment

Nice to have

Familiarity with identity and access management tooling (Okta, SCIM provisioning, SSO); Experience with Zero Trust or network access tools (Twingate, Cloudflare Access, or similar); Exposure to SIEM platforms, log aggregation, or detection engineering; Familiarity with SaaS security posture management (SSPM) or CASB concepts; You've worked somewhere where PII or sensitive data was the core product
