Friendly Neighborhood Recruiter l Start-up Scaler l SaaS l AI

Voltage Park is building an AI Cloud Infrastructure business from the ground up. As part of this effort, we’re looking for a Senior Security Engineer to play a critical technical role in our security team. You’ll be responsible for building internal security tooling, conducting in-depth threat assessments, leading penetration testing efforts, and supporting forensic investigations.

You’ll work closely with the CISO and engineering teams to implement robust, scalable security controls, through direct hands-on engineering. This is an ideal role for someone who wants to go deep into execution, automation, and offensive testing in a fast-paced environment.

If you have strong experience crafting custom payloads or exploit chains, and evaluating CVEs for real-world exploitability across diverse environments, that’s a major plus. We’re especially interested in engineers who go beyond scanning, those who understand exploit primitives, can assess actual risk based on context, and enjoy digging deep into technical edge cases.

This is a fully remote role, but you must be located in the United States. We are not able to provide sponsorship for this position.

Requirements

• 4-7 years of experience in security engineering, offensive security, or related technical roles.
• Proficient in scripting (Python, Bash, PowerShell) and familiar with CI/CD and DevOps workflows.
• Hands-on experience with red team or penetration testing methodologies and tooling.
• Strong understanding of common vulnerabilities, exploit techniques, and secure architecture patterns.
• Experience building or automating security assessments and scanning pipelines.
• Familiar with network security fundamentals and tools (firewalls, packet inspection, VPNs).
• Exposure to forensic tooling, endpoint analysis, and log investigation is a plus.
• Comfortable working independently with high accountability and attention to detail.

What You’ll Do

Security Tooling & Automation:

• Build, maintain, and improve internal security tooling to support threat detection, monitoring, and compliance.
• Develop automation for vulnerability scanning, dependency analysis, secrets detection, and CI/CD pipeline security.
• Integrate security tools with development workflows to provide fast, actionable insights to engineering teams.
• Conduct vulnerability assessments across infrastructure, applications, and third-party integrations.
• Perform targeted penetration tests simulating real-world attack scenarios.
• Document and communicate findings clearly, working with engineers to design practical remediations.
• Support continuous improvement of our security posture through ongoing assessment cycles.

Threat Modeling:

• Participate in threat modelling sessions during system and feature design.
• Identify abuse cases, trust boundaries, and attack vectors; propose mitigations aligned with engineering goals.
• Support investigations by analyzing endpoint, network, and log data during and after incidents.
• Assist in root cause analysis and develop scripts or queries to identify indicators of compromise (IOCs).
• Collaborate with other responders to provide technical depth during containment and remediation efforts.

Security Monitoring & Tuning:

• Tune and improve detection logic in collaboration with our SOC tooling or EDR.
• Analyze data from network devices, logs, and other telemetry sources to support detection engineering.

Why this Role Matters

We’re scaling quickly, and our ability to defend against threats depends on having strong technical operators who can build, test, and improve real defenses. You'll be hands-on, working cross-functionally, helping build the tools and conduct the tests that keep us safe every day.
