Staff Security Engineer - Vulnerability Management & Automation

Description About Us At Slack, we are committed to making people’s working lives more secure. We are serious about protecting our infrastructure, operations, and most importantly, our customers’ data. Our Vulnerability Management team plays a pivotal role in identifying, assessing, and mitigating security risks across our entire infrastructure. We take a systemic approach to security and strive to ensure we provide low friction, high-impact security across everything we do. Slack has a positive, diverse, and encouraging culture—we look for people who are curious, innovative, and work to be a little better every single day. In our work together we aim to be smart, humble, hardworking and, above all, collaborative. If this sounds like a good fit for you, read on ahead! What you will be doing As a Staff Software Engineer on the Vulnerability Management team, you will serve as a technical anchor for a team that builds and maintains the systems and tooling we rely on to detect, track, and remediate security vulnerabilities across our organization. You will drive technical strategy for how we automate and scale vulnerability management, work closely with security engineers, product teams, and infrastructure partners to tackle complex cross-functional challenges, and help raise the bar for how the team builds software. This is a high-impact, high-ownership role for someone who wants to do meaningful engineering work while shaping how security gets done at scale. Key Responsibilities Own the technical architecture and roadmap for vulnerability management tooling, including systems that automate identification, prioritization, tracking, and remediation of vulnerabilities across diverse ecosystems and environments. Lead the design and development of high-quality, scalable engineering solutions, balancing long-term maintainability with the practical needs of a fast-moving security organization. Drive integration strategy across vulnerability scanners, aggregation pipelines, and downstream systems, making principled decisions about data ownership, tool consolidation, and signal quality. Define and evolve the metrics and reporting frameworks the team uses to measure program effectiveness, moving the organization toward risk-based measurement rather than activity-based compliance tracking. Partner with cross-functional stakeholders including infrastructure, platform engineering, and product security teams to identify opportunities to embed security automation deeper into the development lifecycle. Identify systemic gaps and ambiguous, high-priority problems that cut across team boundaries, propose solutions, and drive them to completion with or without direct authority. Provide technical mentorship, design reviews, and code reviews to engineers on the team, helping others grow and maintaining a high standard of engineering craft. Contribute to architectural decisions, tooling selections, and process improvements that have lasting impact on how the broader security organization operates. What you should have: U.S. Citizenship or Permanent Residency (Green Card holder). We are unable to provide visa sponsorship for this role. 8+ years of industry software engineering experience, with a meaningful portion of that spent in security engineering, platform engineering, or infrastructure-adjacent domains. Deep proficiency in Python, with a strong track record of writing production-grade, tested, maintainable code in complex systems. Demonstrated experience owning and delivering end-to-end engineering projects, from early-stage design through production deployment and ongoing operation. Solid understanding of vulnerability management concepts, including how vulnerabilities are discovered, classified, prioritized, and remediated in enterprise environments. Experience building or maintaining integrations with security tooling such as vulnerability scanners, SIEM systems, or similar platforms. Comfort working with CI/CD pipelines, version control workflows, and modern software delivery practices. Experience working across teams and communicating technical concepts clearly to both engineers and non-technical stakeholders. Strong judgment in the face of ambiguity, and a track record of asking the right questions before building rather than after. Nice-to-Have: Hands-on experience with vulnerability management tooling such as Wiz, Tenable/Nessus, Twistlock, or similar products, particularly in cloud or containerized environments. Familiarity with compliance frameworks relevant to government or regulated environments, such as FedRAMP or DoD IL5/IL6. Experience working with large-scale vulnerability aggregation systems or homegrown data pipelines that normalize findings across multiple scanners. Background in building automated remediation workflows, such as automated PR generation for dependency vulnerabilities or patch orchestration across diverse package ecosystems. Experience with cloud environments (AWS, Azure, GCP) and containerized workloads at scale. Contributions to the security or software community through open-source projects, published research, conference talks, or similar. For roles in San Francisco and Los Angeles: Pursuant to the San Francisco Fair Chance Ordinance and the Los Angeles Fair Chance Initiative for Hiring, Salesforce will consider for employment qualified applicants with arrest and conviction records. #J-18808-Ljbffr B Capital
