Scan your resume against ATS criteria for this Senior Security Engineer role at SmartStream.
As a Senior Security Engineer at Smartstream, you will join our Security Engineering Centre of Excellence and serve as a senior technical member across the entire Security Engineering function. You'll be the escalation point for embedded Security Engineers and Security Champions on the most complex problems - novel vulnerability classes, adversarial-AI scenarios, LLM-driven code-scan findings, and regulator-mandated threat-led penetration tests.
This is a hands-on, deeply technical individual-contributor role. You will write code, build tooling, perform tool integrations, run scans across a large enterprise codebase, mentor peers, and help shape how Smartstream uses AI inside the Secure SDLC.
You will work upstream of the VulnOps function, which owns the unified vulnerability backlog and remediation pipeline. Your focus is on original analysis, novel vulnerability classes, adversarial AI, complex penetration testing, variant analysis, and technical mentoring - findings you produce or validate flow into the VulnOps backlog for tracked closure under SLA.
Own and operate LLM-assisted code scanning across the Smartstream product portfolio. Tune prompts and pipelines, triage false positives, validate and demonstrate exploitability of findings where necessary, and drive remediation through the VulnOps backlog in partnership with engineering teams.
. Act as the technical authority for embedded Security Engineers and developers on hard SAST and DAST findings, exploitability assessment, fix design, false-positives elimination, and pattern publication.
Run the in-house adversarial-AI simulation platform and blue-team activities. Manage outsourced red-team engagements and route findings into the VulnOps backlog.
Provide the technical lead during DORA Article 26 threat-led penetration tests when financial-institution customers pull Smartstream into scope.
Lead variant analysis whenever a Critical/High finding is confirmed - identify similar attack vectors across the codebase, produce engineering-grade remediation guidance, and feed the resulting issue set into VulnOps for tracked closure.
Lead internal web-application pen testing (OWASP Top 10, SANS Top 25). Scope and sign off release pen tests; manage outsourced pen-test engagements jointly with the Security Engineering Manager. Findings flow into the VulnOps backlog.
Provide guidance on approved cryptographic libraries, TLS, key management, and secrets handling practices. Partner with engineering teams to ensure secure implementation across products
Set the technical strategy for SBOM, supply-chain scanning, and secret-scanning detection - what to scan, how to interpret reachability, how to triage high-impact dependency CVEs, and which detection rules to use. Operational pipeline ownership sits with VulnOps; the Senior SE owns the technical part of it.
Lead the Security Champions mentoring programme. Run developer security training workshops. Be the escalation path for embedded SEs on novel findings.
Evangelise a security-first culture across engineering - code reviews, design reviews, brown bags, internal comms.
Support annual customer-driven penetration tests of Smartstream products.
