Staff / Staff II - Application Security Engineer

Omnissa is an AI-driven digital work platform company providing secure, flexible digital workplace solutions. The Staff / Staff II Application Security Engineer will provide technical leadership for application security across the product portfolio, including setting security architecture direction, leading threat modeling, conducting secure code reviews, researching vulnerabilities, and improving security programs. The role will influence engineering teams, drive remediation and automation, and mature practices such as SDL, penetration testing, and security champions programs.

Responsibilities:

• Set technical direction for application security across the portfolio — defining standards, patterns, and guardrails adopted by engineering teams at scale
• Lead threat modeling across distributed, cloud-native, and mobile architectures as a repeatable practice embedded in the development lifecycle, not a one-off exercise
• Define security architecture reference designs that, when followed by engineering teams, remove the need to security-review that aspect on a per-feature basis
• Identify architectural risk early and influence roadmap and design decisions before implementation begins
• Perform manual code review and application security testing across Java and C++ codebases; codify findings into reusable guidance engineers can act on without follow-up
• Scale code review coverage using AI-assisted analysis and custom CodeQL queries tuned to Omnissa's codebase and vulnerability patterns
• Conduct variant analysis to ensure confirmed vulnerability classes are remediated consistently across the codebase, not in isolation
• Triage and validate externally reported vulnerabilities — assess exploitability, severity, and business impact, and drive remediation to closure across team boundaries
• Translate individual findings into systemic recommendations that address root-cause design or implementation gaps across products
• Define and evolve the SDL — identify gaps, drive measurable improvements, and own the iteration cycle
• Improve the feature security review program so security work shifts left into design and scales across teams, rather than landing as a release gate
• Mature the product penetration testing program — define scope, methodology, and cadence; ensure findings drive systemic fixes, not one-off patches
• Build and scale the security champions program; mentor engineers and create training that extends security capability beyond the security team
• Establish metrics that make program effectiveness visible to engineering and product leadership
• Build a deep understanding of the product architecture, development toolchain, and release process across multiple product areas. Begin influencing in-flight architectural and design decisions, and identify the highest-leverage gaps in the current security program
• Own the security strategy for a significant area of the portfolio. Set direction that other engineers execute against, drive cross-team prioritization of security work, and shape backlog and roadmap decisions. Iterate improvements on the current SDL
• Deliver measurable, org-level improvements in security posture — e.g., materially reduced mean time to remediation, broadened threat model coverage, or new automation adopted in production across teams. Be recognized as a go-to technical authority on application security and a multiplier of the team’s overall effectiveness
• Report to the Director of Product Security and take technical direction from the Manager of Application Security, while operating with a high degree of autonomy
• Work closely with a committed team of security engineers, product managers, and developers focused on innovation and getting things done
• Build trust among team members and stakeholders, committing to customer success
• Operate in a transparent, communicative environment that emphasizes work-life balance and having fun at work
• Identify and drive improvements to security processes - both internal workflows and partner-facing interfaces - that reduce friction for development teams and increase the daily effectiveness of security engineers

Requirements:

• 10+ years of hands-on application security experience, with demonstrated technical depth and a track record of influence beyond your own work
• Deep knowledge of application security vulnerabilities and mitigation techniques, and the judgment to prioritize them by real business and customer impact
• Proven ability to lead threat modeling, secure design, and security architecture for complex distributed and cloud-native systems
• Proficiency in Java or C++, with the ability to read, reason about, and review production code
• Security breadth across multiple domains — application, system, cloud, and mobile
• A demonstrated history of driving technical change and raising the security bar across teams, and of mentoring senior engineers
• Excellent documentation and communication skills, including the ability to influence engineering and product leadership
• Self-starter who is adaptable, works independently, and brings clarity to ambiguous problems
• A pragmatic mindset; able to identify practical short term and long term strategic solutions
• This job requisition is not eligible for employment-based immigration sponsorship by Omnissa
• Experience testing agentic AI systems, and the ability to leverage AI tooling across security testing, triage, and documentation workflows
• Experience building automation solutions that improve the security process at scale
• Prior experience as a pen tester for a multi-tenant SaaS provider
• Bachelor's degree in Computer Science or a related field preferred, or equivalent combination of education and relevant professional experience
