Senior Security Engineer II, Application Security (Remote Eligible)

-REMOTE, USA-

For over 20 years, Smartsheet has helped people and teams achieve–well, anything. From seamless work management to smart, scalable solutions, we’ve always worked with flow. We’re building tools that empower teams to automate the manual, uncover insights, and scale smarter. But more than that, we’re creating space– space to think big, take action, and unlock the kind of work that truly matters. Because when challenge meets purpose, and passion turns into progress, that’s magic at work, and it’s what we show up for everyday.

AI is changing what application security can accomplish. We're not just securing AI; we're using it as a force multiplier to see more risk, act faster, and scale security across a platform used by millions of customers globally. We're looking for a Senior Security Engineer II to join our Application Security team who can do both: bring deep expertise in securing AI-integrated systems, and deploy AI and automation to drive risk visibility and reduction at a scale no traditional security program can match on its own.

This is a high-ownership, technically demanding role for an experienced application security engineer. You will work at the intersection of threat-informed design, engineering automation, and applied AI, doing consequential security work that directly shapes the posture of a modern SaaS platform. If you're a security engineer who writes code to solve security problems, can read a production codebase to find what a scanner misses, and wants your work to matter beyond a ticket queue, we want to talk.

You will report to the Manager, Application Security , based in our Bellevue, WA office, or you may work remotely from anywhere in the US where Smartsheet is a registered employer. 

You Will:

  • Secure AI Systems and Use AI to Scale Security: Conduct security reviews and threat modeling of AI-integrated product features (LLM workflows, agentic pipelines, model APIs) with working knowledge of AI-specific risk classes including prompt injection, model manipulation, and runtime control gaps; and in parallel, deploy AI and automation as a force multiplier by building tooling, pipelines, and integrations that extend the team's reach, accelerate triage, and drive risk visibility at a scale manual effort alone cannot achieve.
  • Deliver Application Security Reviews: Own end-to-end security assessments for high-risk features and services (threat modeling, architecture review, targeted code review, and security testing) embedded in the product development lifecycle. Work directly with engineering teams to surface and close risk before it ships, with enough technical credibility to influence design decisions, not just document findings.
  • Advance CI/CD Pipeline Security: Operate and evolve the security scanning controls embedded in Smartsheet's GitLab pipelines (SAST, SCA, secrets, IaC scanning). Tune tools, engage teams on findings, and build automation that reduces false positive burden and improves how developers experience security feedback.
  • Run Bug Bounty Operations: Serve as the expert validation layer for Smartsheet's bug bounty program, reproducing and assessing complex, multi-step researcher submissions requiring authenticated context and deep platform knowledge, making defensible severity and payout decisions, and owning program operations including researcher engagement, metrics, and continuous improvement. 

You Have:

  • Experience: 8+ years in application security, with a track record of owning complex, multi-capability work in a product security or AppSec engineering role.
  • Software engineering foundation: Fluent in one or more modern languages (Java, Python, TypeScript/JavaScript, Go, Ruby, or equivalent); you identify security-relevant patterns without relying on tooling and write automation that others adopt.
  • AI security: Hands-on experience securing AI-integrated applications (LLM systems, agentic workflows, model APIs) and demonstrated experience deploying AI and automation to scale security functions or extend team reach. You bring both skill sets.
  • Security review depth: Threat modeling, architecture review, and code review for complex SaaS features; you produce findings engineering teams can act on and carry enough technical credibility to influence design decisions, not just document them.
  • Manual web application testing: Independent, hands-on validation of complex, multi-step authenticated vulnerabilities; you confirm what scanners flag and find what they miss.
  • Bug bounty experience: Operator, active researcher, or both; direct experience with triage, severity calibration, and researcher communication.
  • CI/CD pipeline security: Working knowledge of SAST, SCA, secrets, and IaC scanning in modern pipelines, with experience engaging teams on findings and improving signal quality.
  • Cloud security fundamentals: Working knowledge of AWS, GCP, or Azure sufficient to tie application-layer risk to the infrastructure it runs on; you understand where the application ends and the cloud begins.
  • Legally eligible to work in the U.S. on an ongoing basis
  • BS or MS in Computer Science, a related field, or equivalent industry experience

NICE TO HAVE:

  • Experience with agentic security, MCP security, or adversarial evaluation of autonomous AI systems.
  • GitLab CI/CD experience, including security policy pipeline configuration and scanning job integration.
  • Active bug bounty researcher with published findings, CVE credits, or hall of fame recognition.
  • Penetration testing program management experience: scope definition, vendor coordination, and finding validation with third-party testers.

Current US Perks & Benefits:

  • Employer subsidized medical/vision and dental coverage for full-time employees
  • 401k Match to help you save for your future (50% of your contribution up to the first 6% of your eligible pay)
  • Monthly stipend to support your work and productivity
  • Flexible Time Away Program, plus Sick Time Off
  • US employees are automatically covered under Smartsheet-sponsored life insurance, short-term, and long-term disability plans
  • US employees receive 12 paid holidays per year
  • Up to 24 weeks of Parental Leave
  • Personal paid Volunteer Day to support our community
  • Opportunities for professional growth and development including access to Udemy online courses
  • Company Funded Perks, including a counseling membership, local retail discounts, and your own personal Smartsheet account
  • Teleworking options from any registered location in the U.S. (role specific)

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
