About The Position

We're looking for an experienced, hands-on Security Engineer to secure XBOW's product, cloud, and platform as we scale. This is a technical individual contributor role focused on building security into how we design, ship, and operate systems. You'll work closely with engineering and platform teams across application security, cloud security, vulnerability management, and incident response. The core of this role is security engineering ownership: improving preventive controls, detection quality, and response readiness, while driving remediation of real risks in production.

Requirements

5+ years of experience in security engineering, product security, cloud/platform security, or closely related roles
Strong hands-on experience securing cloud environments (AWS, Azure and GCP)
Comfortable owning technical security problems end-to-end in fast-moving environments
Hands-on experience with product/application security in engineering environments (secure design reviews, threat modeling, code-level risk discussions)
Experience operating AppSec tooling and processes at scale (SAST, SCA, secrets, IaC scanning)
Strong vulnerability triage and remediation management experience, including risk-based prioritization and SLAs
Experience with CNAPP (or equivalent cloud security platforms) and tuning findings for engineering actionability
Working knowledge of Kubernetes/container security in production systems
Ability to partner with developers and platform teams to ship secure defaults without blocking delivery
Comfortable writing scripts and automations to improve security reliability and scale
Experience in incident response, investigation, and post-incident hardening in cloud-native environments
Security-minded, detail-oriented, and a proactive communicator in remote-first teams

Nice To Haves

Multi-cloud experience beyond AWS (e.g., Azure/GCP/OCI)
Offensive security/pentesting background and ability to convert findings into durable engineering fixes
Experience scaling security at a startup from early stage to audit-ready maturity
Relevant security certifications (e.g., OSCP, OSCE, AWS Security Specialty, Kubernetes security certs)

Responsibilities

Design and implement security controls across cloud, infrastructure, and internal platforms
Partner with engineering to harden cloud architecture, IAM, and infrastructure
Own product security reviews for new features, services, and major architecture changes
Drive threat modeling and secure design decisions early in the SDLC
Operate and improve AppSec workflows (SAST, SCA, secrets scanning, IaC scanning)
Triage vulnerabilities across application, container, and cloud findings, and drive remediation with risk-based SLAs
Define and run the vulnerability management lifecycle: intake, prioritization, exception handling, validation, and reporting
Improve CNAPP coverage and finding quality across cloud accounts and workloads
Improve Kubernetes and container security posture
Monitor, investigate, and respond to security events and incidents
Build automation to improve security operations, access workflows, and incident response
Support the wider teams by providing timezone coverage for our fully remote organization.
