Senior Cybersecurity

Ethereum Technologies LLC; Irving (TX); On-site; USD 180,000 - 240,000; Full time

Job summary

Ethereum Technologies is seeking a senior security professional to analyze complex security data, map cryptographic vulnerabilities, and group applications by infrastructure and vulnerability signatures. You will build sanitized mappings for offshore remediation teams, while guiding PQC readiness and hybrid TLS/key management.

The role requires hands-on cryptography expertise and willingness to work on-site with strict data-protection protocols, including clearance eligibility.

Qualifications

• Senior-level cybersecurity expertise with hands-on cryptography and data analysis.
• Deep knowledge of TLS 1.3, IKEv2/IPsec, AES-256, and PQC concepts.
• Proficient at parsing JSON, SBOMs, and CBOMs to extract trends.
• Experience with legacy, 10-20 year old enterprise apps and hardware.
• Eligible for security onboarding and on-site work with strict data handling.

Responsibilities

• Analyze complex security data and parse JSON/SBOM/CBOM scans across ~128 apps.
• Map cryptographic vulnerabilities and ensure TLS 1.3 adoption and modern ciphers.
• Group applications by infrastructure and vulnerability signatures under constraints.
• Build sanitized mapping tables for offshore remediation teams with zero data leakage.
• Guide PQC readiness and hybrid TLS/key management strategies.

Job description

US Citizen, Green Card, H-1B, OPT-EAD, CPT, Other

What You Will Do:

• Analyze Complex Security Data: Securely parse and analyze raw JSON/SBOM/CBOM scans (generated by tools like Sonatype and CBOM Kit) across an enterprise portfolio of ~128 applications.
• Map Cryptographic Vulnerabilities: Identify critical deviations from target North Star standards, specifically mapping migrations from TLS 1.0/1.2 to TLS 1.3, weak ciphers to AES-256-GCM, and outdated SSH host keys to modern standards.
• Identify Ecosystem Patterns: Group applications by their infrastructure characteristics and vulnerability signatures, factoring in complex constraints like hardware load balancers, IoT device memory limits, and legacy undocumented business rules.
• Architect Characteristic Maps: Build comprehensive, sanitized technical mapping tables that define exactly what remediation templates need to be built by the offshore Cloud/AI team, ensuring zero proprietary vulnerability data leaves the secure network.
• Drive PQC Readiness: Guide the structural transition logic for Post-Quantum Cryptography (PQC) readiness, focusing on hybrid TLS implementations and modern key management.

Must-Have Qualifications:

• Senior-Level Expertise: Extensive, hands-on background in Cybersecurity, Cryptography, and Security Data Analysis.
• Deep Cryptographic Knowledge: Absolute technical mastery of enterprise encryption protocols, including TLS 1.3, IKEv2 IPsec, AES-256, and modern PQC concepts (e.g., ML-KEM, ML-DSA).
• Data Parsing Skills: High proficiency in parsing, querying, and analyzing raw security data logs (JSON, SBOM, CBOM formats) to extract actionable trends.
• Legacy Infrastructure Acumen: Ability to understand and navigate the constraints of 10-to-20-year-old revenue-generating enterprise applications and hardware.
• Security Clearance/Compliance: Must be eligible and willing to clear expedited enterprise security onboarding and work on-site under strict, zero-data-export handling protocols
