Summary

We are looking for an Application Security Engineer to join the Information Security team. In this role, you will help keep the OneStream platform secure by triaging and validating findings from application security tools, partnering with engineering teams on practical remediation, and supporting security design reviews and threat modelling for new features throughout the SDLC. You will also use automation and AI-assisted tooling to take on repetitive work, such as reviewing and summarizing findings, so the team can focus on higher-impact security problems.

The ideal candidate has experience in software engineering and security, with a solid foundation in secure development practices, familiarity with application security tools (SAST, SCA, and DAST), and a passion for securing our platform for our customers. Working knowledge of C# and .NET is a bonus. We are looking for a go-getter who is eager to learn, collaborates well with teams across all levels of the organization, and brings a pragmatic approach to security that keeps delivery moving. This position requires the ability to explain and discuss technical details with both technical and non-technical audiences.

Triage and validate findings from application security tools (SAST, SCA, and DAST), prioritizing by exploitability and real-world risk.
Partner with Development and Engineering teams to remediate vulnerabilities with clear, practical guidance.
Participate in security architecture reviews and threat modelling for new features and services.
Integrate and tune application security tooling in CI/CD pipelines so security checks fit naturally into developer workflows.
Use AI-assisted tools and automation to streamline repetitive tasks such as reviewing and summarizing findings, removing duplicates and false positives, creating tickets, and reporting.
Write scripts and lightweight tooling to automate recurring security workflows.
Review the SDLC and software supply chain, including third-party dependencies, to identify opportunities to improve security.
Perform targeted manual validation of findings when needed to confirm impact.
Track remediation progress, and document and report security concerns and trends.
Contribute to secure development guidance, standards, and developer education.
Work with other members of the Security team to share findings and improve overall security posture.

Required Education and Experience

BSc/BA in Computer Science, Engineering, or relevant field, with 5+ years of experience in application security, software development, or DevSecOps OR
MSc/MA in Computer Science, Engineering, or relevant field, with 1+ year of experience in application security, software development, or DevSecOps OR
Assoc. in Computer Science, Engineering, or relevant field, with 5+ years of experience in application security, software development, or DevSecOps

Preferred Education and Experience

Experience writing or reviewing C# & .NET code (a strong plus).
Software development background, with an understanding of secure coding practices and common vulnerability classes (e.g., OWASP Top 10).
Hands-on experience with SAST, SCA, and/or DAST tools and triaging their output.
Experience using AI tools or LLMs to automate repetitive work, such as reviewing findings, summarizing results, or drafting remediation guidance.
Experience with CI/CD pipelines and DevSecOps practices.
Scripting or automation experience (e.g., Python, PowerShell).
Familiarity with threat modelling methodologies (e.g., STRIDE).
Exposure to Burp Suite or similar tools for validating web application findings.
Familiarity with security risk management, SOC2, FedRAMP, security policies & procedures, or security auditing.
Any industry recognized certifications, for example:
CompTIA Security+
Certified Secure Software Lifecycle Professional (CSSLP)
GIAC Secure Software Programmer - .NET (GSSP-.NET)
Other application security or secure development certifications
Outstanding communication skills

Knowledge, Skills, and Abilities

Ability to triage and prioritize security findings based on exploitability and business impact.

Understanding of secure design principles, with the ability to contribute to security architecture reviews and threat modelling.
