This gives us a unique opportunity to transform an entire category and set a new benchmark for how modern revenue teams operate.

Join us to help transform how companies around the world run revenue — and build the platform that will guide leading revenue teams into the future.

THE OPPORTUNITY

At Salesloft, our Staff Security Engineer will be pivotal to our company’s success. You will be a key member of our fast-growing and high-performing Security Engineering team and will be our technical champion for architecting, scaling, and embedding robust security controls across our global cloud infrastructure and application stack. We believe that the most innovative software products are built on a foundation of uncompromised trust, resilience, and security.

On a day-to-day basis, you will be responsible for leading the architectural design of our security systems, driving threat modeling across product engineering teams, and building automated security tooling into our CI/CD pipelines. Specifically, you will:

Architect Security Solutions: Design, implement, and maintain enterprise-grade security infrastructure (e.g., identity and access management, cloud security posture management, encryption services, and network defenses).

Drive DevSecOps Automation: Build and scale automated security testing (SAST/DAST/SCA) directly into our deployment pipelines to catch vulnerabilities early and enable developers to ship code securely.

Lead Threat Modeling & Reviews: Partner closely with Product Engineering architects during the design phase of new features to identify security risks, perform threat modeling, and define mitigation strategies.

Incident Response & Engineering: Act as a tier-3 technical escalation point for complex security incidents, leading deep-dive forensics, root-cause analyses, and building long-term engineering fixes to prevent recurrence.

Set Technical Direction: Define and drive multi-quarter security architecture strategy and roadmap, partnering with Security and Engineering leadership to prioritize investments by risk and business impact.

Scale Through Others: Establish secure-by-default patterns, paved roads, and reusable guardrails that let engineering teams build securely without a security engineer in the loop.

In addition to working with amazing colleagues who exemplify our ‘team over self’ core value, you will also have the opportunity to scale the security posture of an industry-leading revenue workflow platform that handles highly sensitive data for the world's largest enterprises. You will have an opportunity to make a difference.

WHAT WE’RE LOOKING FOR:

We are seeking a highly technical, visionary, and proactive security leader who combines deep domain expertise with a passion for building scalable infrastructure. You are someone who thinks like an attacker but builds like a defender, with the technical credibility to influence product engineering teams and the strategic mindset to align security initiatives with business growth. If you’re looking for an opportunity to shape security strategy and scale your impact across the company, then becoming a Staff Security Engineer is th
