This is a hands-on engineering role you'll design, implement, and automate secure systems across our platform, working closely with backend and DevOps teams to ensure that security is built into everything we deploy. You'll also play a key role in maturing our compliance posture (SOC 2, HIPAA, ISO27001, GDPR, HITRUST) as we scale.

What You'll Do

  • Compliance programs (SOC 2, HIPAA, ISO 27001, etc.)

  • Incident response planning and postmortems

• Collaborate with engineering to embed security into the development lifecycle

• Build and maintain security monitoring, alerting, and response systems

• Act as a security advocate within the team, mentoring engineers on best practices

Who You Are

• 3+ years of professional software engineering experience (writing and reviewing production code)

• 2+ years of infrastructure or DevOps experience (cloud platforms, networking, automation, etc.)

• Strong understanding of security risks and mitigations (OWASP, cloud security, CI/CD best practices)

• Experience with infrastructure-as-code (Terraform, CloudFormation, Pulumi, etc.)

• Hands-on experience with security tooling (static/dynamic analysis, vulnerability scanning, intrusion detection, etc.)

• Bias for ownership, automation, and continuous improvement

• Nice to have:
