Senior Security Infrastructure Engineer

You'll work alongside diverse, cross-border teams and supportive colleagues who share knowledge and want to see you succeed. Wrike is looking for a Sr. Security Infrastructure Engineer to own and evolve security for our production and cloud environments, with a strong focus on network and infrastructure security. You'll design and harden the controls that keep our world secure — and you'll be the person who spots the gap before it becomes an incident.

• Own and evolve security for Wrike's production and cloud environments, with a strong focus on network and infrastructure security.
• Design, implement, and improve network security controls, including:
• Internal network segmentation and lateral-movement (east-west) restrictions
• WAF operations and tuning
• Egress filtering
• Risk- and exposure-based sequencing of remediation work
• Run structured first-pass security reviews of cloud environments, checking for:
• Publicly exposed storage
• Open management ports
• Gaps in logging/audit trail coverage
• Long-lived or stale credentials
• Over-privileged principals and accounts
• Maintain visibility into our external attack surface, including:
• DNS enumeration and certificate transparency log monitoring
• External scanning of IP ranges
• Dedicated ASM tooling (e.g., Rapid7 Surface Command)
• Continuous configuration drift detection tied to an asset inventory with clear ownership assignment
• Partner with System & Data Engineering and other ops teams to embed security into architecture and change management (design reviews, sign-offs, "secure by default" patterns).
• Educate and coach engineers and operations teams on security practices through reviews, consultations, and targeted training.
• Identify, track, and determine mitigation strategies for security risks.

• Proven track record as a security subject-matter expert, guiding engineering teams in end-to-end secure system design, with a focus on network architecture and cloud services.
• Hands-on experience designing network segmentation/architecture and operating firewall / IDS-IPS platforms in production — you think in layers, not a checklist: internal zoning/segmentation to cut east-west movement and edge protection in front of public-facing apps (Cloudflare-style WAF managed + custom rules, rate limiting, bot/DDoS protection, TLS), sequenced by which assets are most exposed or highest-risk first.
• Experience running structured, read-only-first reviews of cloud environments you've never seen before, working through identity and permissions (Azure RBAC/Entra or GCP IAM — over-privileged principals, standing admin, long-lived credentials), public exposure (open management ports, public storage/blob, public IPs), logging and visibility (activity/audit and flow logs), network rules (NSGs/firewall), and secrets handling — in that order of priority, before proposing changes. Primary focus on Azure permissions and configuration, with working knowledge of GCP and on-prem components.
• Experience maintaining attack surface visibility on the assumption that the known asset inventory is incomplete — discovering unregistered/shadow assets via DNS enumeration, certificate transparency logs, IP-range/cloud enumeration, external scanning, and ASM tooling (e.g., Rapid7 Surface Command) — run as a continuous, monitored process with drift detection and alerting, not a one-time scan, with ownership assigned to whatever turns up.
• Skilled at identifying gaps in existing network and cloud security architecture/configuration and recommending changes (authentication, authorization, network segmentation, bastion host setup, etc.).
• Able to lead the technical direction and architecture of our cyber security defense capabilities, including enterprise security posture management.
• Strong communicator, able to explain complex security concepts and risks to both technical and non-technical audiences.

• Ability to balance security principles with business needs.
• Security certifications (e.g., CISSP, GIAC, a network security certification such as CCNP Security, etc.).
• Strong understanding of Microsoft Azure; working knowledge of Google Cloud Platform is a plus.
• Exposure to data security posture management (DSPM) or cloud-native data security controls — a strong plus.
• Experience hardening and tuning WAF rules (Cloudflare WAF experience specifically is a strong plus).
• Security isn't just a job for you — it's a hobby, and it shows in how you work.

• Intro call with a Recruiter
• Technical interview
• Cultural interview

Your recruitment buddy will be Aleksandar Chernev, Senior Technical Recruiter.
