Security Solutions Engineer

The role

We are seeking a Security Solutions Engineer with a strong background in strategic solution evaluation, vendor assessment, and hands-on Proof-of-Concept (PoC) validation. This role is a crucial bridge between identifying customer security requirements and implementing best-in-class, enterprise-grade solutions. You will be responsible for defining the criteria, researching the market, and executing technical validation for all major security tooling and services adopted by the company.

Key responsibilities:

• 1. Strategic Research & Requirement Definition: Proactively analyze customer expectations, regulatory/compliance drivers, and threat models to define precise functional and non-functional requirements for new security solutions.
• Market Analysis & Scouting: Conduct thorough market scans to identify cutting-edge security products, platforms, and vendors across key domains (e.g., CSPM/CNAPP, DLP, IAM/IGA, EDR/XDR, data security, Kubernetes security, and AI/ML security).
• Vendor Due Diligence: Evaluate potential vendors based on technical capability, security posture, integration requirements, roadmap, data residency/compliance, and support quality, and shortlist candidates for the PoC phase.

2. Technical Validation & Proof-of-Concept (PoC) Leadership:

• PoC Planning & Design: Develop detailed, objective, and threat-aligned test plans and success criteria for all security solution Proof-of-Concepts (PoCs), including quantitative success metrics, coverage of key attack scenarios, and opportunities for automation.
• Hands-on Environment Setup: Independently architect and deploy isolated PoC environments that accurately simulate production infrastructure (e.g., cloud VPCs, Kubernetes clusters, IaC data, workloads).
• Testing & Analysis: Execute security research methodologies within the PoC to test the vendor solution's effectiveness.
• Artifact Generation: Document all findings, including technical performance data, integration challenges, security gaps discovered, and clear comparative analysis metrics.

3. Decision Support & Communication:

• Recommendation & Insight: Deliver data-driven reports and presentations to security and product leadership, providing a clear recommendation for the optimal solution and vendor selection.
• Integration Planning: Work with Security Engineering, Platform/Infra, and DevOps teams to ensure solutions are feasible to integrate, operate, and scale, and to hand off PoC learnings into implementation plans.

Must-haves:

• Experience: Minimum 6+ years in Security Engineering, Security Architecture, or Security Research focused on solution validation and vendor management.
• Technical Depth: Deep understanding of cloud security principles (AWS/Azure/GCP, Kubernetes, least privilege, IaC scanning, identity-centric security).
• Programming and Automation: Strong scripting/ programming skills (Python, Go) for automating PoCs and integrating tools.
• Solutions Expertise: Experience with two or more enterprise-grade security tools (SIEM/SOAR, EDR, Vulnerability Management, Secrets Management).
• PoC Proficiency: Ability to plan and execute complex PoCs.
• Soft Skills: Strong analytical, written and verbal communication.

Nice-to-have:

• Cloud-heavy company experience; compliance-focused industries; CISSP/CCSK or cloud certs; contributions to security standards/open-source.

Benefits & Perks:

• Competitive compensation
• Career growth and learning opportunities
• Flexibility and ownership
• Collaborative culture
• Impactful AI projects
• International environment and talented teams
