Job Description SummaryThe Lead Vulnerability Research Engineer will be a hands-on technical leader within Vulnerability Management, responsible for discovering, validating, and operationalizing knowledge of vulnerabilities that present credible risk to the firm. The role combines threat-informed vulnerability research, offensive security, software engineering, data analysis, and security automation. The engineer will investigate emerging vulnerabilities and attack techniques; determine exploitability, reachability, and enterprise relevance; and convert research into repeatable detection, prioritization, validation, and remediation capabilities at scale.
The engineer will responsibly apply AI-assisted techniques to accelerate hypothesis generation, code and patch analysis, test development, finding correlation, exploit-path reasoning, and remediation guidance. AI output must remain subject to rigorous human validation, security and privacy controls, reproducibility standards, and measurable quality outcomes. The role will partner across threat intelligence, security operations, application security, infrastructure, cloud, engineering, architecture, and technology risk teams to reduce exposure before adversaries can act.
Job DescriptionThis position follows a hybrid work model, with an expectation to be in the office 3 days per week at the St. Petersburg, FL Corporate Office location.Please note: This role is not eligible for Work Visa sponsorship, either currently or in the future.Responsibilities- Lead threat-focused vulnerability research across enterprise applications, APIs, operating systems, network devices, cloud services, containers, open-source components, commercial products, and emerging AI-enabled technologies.
- Continuously analyze threat intelligence, vendor advisories, public exploit research, malware and campaign reporting, security-research disclosures, and internal telemetry to identify vulnerabilities with credible relevance to the enterprise.
- Perform authorized, controlled technical research to validate vulnerability conditions, affected versions, attack prerequisites, exploitability, reachability, likely impact, and available mitigations without creating unnecessary operational risk.
- Reproduce vulnerabilities in isolated lab environments; analyze patches, source code, binaries, configurations, protocols, and proof-of-concept artifacts; and create defensible evidence that distinguishes theoretical exposure from actionable risk.
- Develop safe detection and validation content such as authenticated checks, queries, signatures, scripts, test harnesses, configuration assessments, and exposure analytics. Ensure research artifacts are reviewed, version-controlled, documented, and designed to avoid disruption.
- Build production-quality automation and integrations that ingest, normalize, enrich, correlate, deduplicate, prioritize, ticket, route, retest, and close vulnerability findings across scanners, asset inventories, threat-intelligence sources, software inventories, cloud platforms, endpoint tools, and engineering systems.
- Create threat-informed prioritization models that incorporate active exploitation, adversary behavior, exploit maturity, internet exposure, asset criticality, application context, business service dependency, reachability, compensating controls, data sensitivity, and remediation feasibility.
- Use AI-assisted research capabilities to summarize technical evidence, identify likely vulnerable code paths, compare patches, generate and refine test hypotheses, correlate findings, propose validation steps, and draft remediation guidance.
- Evaluate and govern AI-assisted security workflows for accuracy, hallucination, prompt injection, insecure output, sensitive-data exposure, excessive agency, model and dependency supply-chain risk, reproducibility, auditability, and appropriate human oversight.
- Design human-in-the-loop controls and benchmark AI-assisted workflows using measurable outcomes, including precision, recall, false-positive and false-negative rates, analyst time saved, validation quality, remediation quality, and reduction in time to protective action.
- Provide rapid technical analysis for high-risk and actively exploited vulnerabilities, including concise impact assessments, affected-asset logic, interim mitigations, detection opportunities, validation procedures, and executive-ready risk communication.
- Conduct root-cause and recurring-pattern analysis to identify systemic weaknesses in technology selection, configuration, software dependencies, asset visibility, patch processes, or control coverage; recommend durable preventive improvements.
- Partner with remediation owners to explain technical risk, validate fixes and compensating controls, resolve disputed findings, and support risk-based decisions while maintaining clear evidence and accountability.
- Define and report program metrics such as research-to-detection time, time to enterprise impact assessment, vulnerable-asset identification coverage, validation accuracy, remediation aging, recurrence, automation effectiveness, and measurable risk reduction.
- Mentor engineers and analysts, establish research standards and playbooks, contribute to technical strategy and roadmaps, and serve as an escalation point for complex vulnerability questions and significant cybersecurity incidents.
QualificationsKnowledge, Skills, and Abilities:- Demonstrated expertise identifying, validating, explaining, and remediating application and API vulnerabilities, including vulnerability classes represented in the OWASP Top 10 and OWASP API Security Top 10.
- Advanced understanding of authentication, authorization, session management, cryptography, input handling, deserialization, server-side request forgery, business-logic abuse, and modern client/server attack surfaces.
- Hands-on experience with SAST, DAST, IAST, SCA, API testing, secrets detection, container scanning, infrastructure-as-code scanning, and penetration-testing tools; ability to tune controls and validate tool output rather than rely solely on scanner severity.
- Strong automation and software engineering capability in Python and at least one of PowerShell, JavaScript/TypeScript, Go, Java, C#, or shell; experience consuming REST/GraphQL APIs, processing structured data, writing tests, and maintaining production-quality code.
- Experience integrating security tools with CI/CD and engineering platforms such as GitHub, GitLab, Azure DevOps, Jenkins, Jira, or comparable technologies.
- Demonstrated experience applying AI-assisted or machine-learning-enabled security tooling to source-code review, vulnerability triage, exploit-path analysis, test generation, remediation support, or finding correlation.
- Ability to critically evaluate AI output, recognize hallucinations and insecure recommendations, protect sensitive source code and data, design human-in-the-loop validation, and establish measurable quality and governance controls.
- Knowledge of secure AI-assisted development risks, including prompt injection, insecure output handling, excessive agency, sensitive information disclosure, model or dependency supply-chain concerns, and misuse of generated code.
- Experience securing cloud-native applications on Microsoft Azure, Amazon Web Services, and/or Google Cloud Platform, including identity, secrets, workloads, APIs, containers, serverless services, and Kubernetes.
- Working knowledge of threat modeling, secure architecture principles, software supply-chain security, SBOM/VEX concepts, artifact integrity, dependency governance, and provenance or attestation practices.
- Ability to communicate technical risk clearly to developers, architects, executives, auditors, and non-technical stakeholders, and to translate findings into prioritized engineering actions.
- Ability to lead through influence, exercise sound judgment under uncertainty, mentor others, and balance security outcomes with client and business needs.
Education/Previous Experience:- Typically requires a Bachelor's degree in computer science, software engineering, cybersecurity, information systems, artificial intelligence, data science, engineering, or a related field and five or more years of relevant experience. An equivalent combination of education, training, industry research, and demonstrated technical experience may be considered.
