Offensive Security Jobs in Nevada (NOW HIRING)

Position Overview

The primary responsibility of the Senior Application Security Engineer (AI-First Development) is to design, orchestrate, and validate the offensive security tooling and adversary-emulation capabilities used to find, prove, and help remediate exploitable weaknesses across applications, infrastructure, the software supply chain, and AI/ML systems. This role operates within an AI-First SDLC in which AI agents serve as primary producers of offensive tooling, exploit proof-of-concept code, attack automation, and adversary-emulation artifacts, while the engineer provides operational direction, context engineering, human-in-the-loop governance, and final accountability for the safety, authorization, and effectiveness of all offensive security work. All testing is performed strictly within authorized scope and defined rules of engagement.

The Senior Application Security Engineer is an experienced security or software engineer with a strong offensive security and secure-coding background who has adopted modern AI-assisted development tools as a core part of their daily workflow and is prepared to grow into deeper agent orchestration, context engineering, and verification responsibilities. This is a tool-builder-forward role: the emphasis is on engineering high-quality offensive tooling and exploit proof-of-concepts as much as on executing engagements.

All duties are to be performed in accordance with departmental and Las Vegas Sands Corp.’s policies, practices, and procedures. All Las Vegas Sands Corp. Team Members are expected to conduct and carry themselves in a professional manner at all times. Team Members are required to observe the company’s standards, work requirements and rules of conduct.

Essential Duties & Responsibilities

• Offensive Tooling Strategy, Agent Workflow Design, and Orchestration

  • Design, build, and maintain AI agent workflows that produce offensive security tooling, exploit proof-of-concept code, attack automation, and adversary-emulation artifacts from engagement objectives and authorized scope.

  • Decompose engagement objectives and threat scenarios into discrete, verifiable offensive tasks and tooling components that AI agents can execute effectively within defined boundaries and rules of engagement.

  • Select and configure appropriate AI models, agent frameworks, and offensive tooling for each workflow based on blast radius, target sensitivity, operational safety, and cost considerations.

  • Construct and maintain operational context that provides agents with approved attack techniques, target environment details, rules of engagement, and safety constraints needed to produce correct, in-scope, and consistent outputs.

  • Contribute to the offensive toolchain, including reusable testing skills, automation hooks, and project memory files that provide persistent context across agent sessions. Authoring of advanced toolchain components may be developed on the job.

  • Systematically capture attack patterns, technique effectiveness, and findings from each engagement and encode them back into shared context, offensive skills, and agent configurations so that subsequent work becomes more reliable.

  • Participate in collaborative refinement sessions to align on engagement objectives, scope, safety constraints, and context packages before agent execution begins.

  • Establish and maintain rules of engagement, scope boundaries, written authorization, and deconfliction procedures for each engagement, ensuring all offensive activity remains legal, authorized, and safe.

• Exploit Validation and Findings Assurance

  • Apply human oversight at governance checkpoints appropriate to the risk level of each workflow, including pre-execution review, in-flight observation, and post-execution audit.

  • Review, test, and approve AI-generated offensive tooling, exploit code, and attack automation, ensuring they meet Sands coding standards, operational safety requirements, and rules of engagement before use against any authorized target.

  • Verify that AI-generated exploits and offensive tooling demonstrate genuine, reproducible impact rather than false positives, and reject findings that cannot be reliably validated or that achieve results outside authorized scope.

  • Partner with Cyber Security on Threat and Risk Assessments, vulnerability remediation, AI agent governance, and approved tooling decisions, surfacing offensive findings and exploitability signals that inform their reviews.

  • Support agent observability practices that track engagement activity, finding rates, exploit reproducibility, and coverage across targets and environments.

  • Produce clear, reproducible engagement deliverables, including technical findings reports, executive summaries, attack-path narratives, and prioritized remediation recommendations tailored to both technical and executive stakeholders.

• Offensive Engineering and Application Exploitation

  • Architect and deliver shared offensive tooling, exploitation frameworks, and reusable testing harnesses spanning web, API, cloud, and binary targets that the security team consumes, using AI-First methodologies as the primary development approach.

  • Define attack methodologies, engagement playbooks, tooling interfaces, and safety controls that serve as foundational context for agent-driven offensive work.

  • Collaborate with cross-functional teams including engineering, QA, Cyber Security, and IT Operations to translate threat scenarios into executable offensive testing workflows.

  • Coordinate with security and engineering teams across global locations to ensure consistency in testing standards, safety controls, and reporting practices.

  • Write, debug, and refactor exploit code, offensive tooling, and attack automation directly when agent outputs require manual intervention or when developing novel exploitation techniques.

  • Ensure delivered offensive tooling meets enterprise standards for reliability, maintainability, operational safety, observability, and responsible use.

  • Design and execute offensive testing of the organization\'s AI and LLM-based systems and agents, including prompt injection, jailbreaks, tool and MCP abuse, guardrail evasion, and model and training-data extraction, drawing on frameworks such as the OWASP LLM Top 10 and MITRE ATLAS.

• Continuous Improvement and Mentorship

  • Evaluate emerging AI models, agent frameworks, offensive tooling, and attack techniques to continuously improve testing effectiveness and coverage.

  • Mentor team members on AI-assisted offensive security practices, context engineering techniques, and verification methodologies.

  • Document attack patterns, prompt and context libraries, and lessons learned to build institutional knowledge.

  • Participate in collaborative construction sessions, guiding agent execution in real time and coaching team members on effective offensive tooling and engagement orchestration techniques.

• Perform job duties in a safe manner.

• Attend work as scheduled on a consistent and regular basis.

• Perform other related duties as assigned.
