About StepSecurity

StepSecurity is the software supply chain security company protecting some of the most important codebases in the world. Our platform secures CI/CD pipelines, developer machines, and AI coding agents for enterprise customers including Circle, Omnissa, Chainguard, Coveo, and Dexcom. Our open source tooling, led by Harden-Runner, is deployed across 13,000+ projects and has been first to detect several high-profile supply chain attacks, including the axios npm compromise, tj-actions, and Trivy incidents.

We are a venture-backed company with strong product-market fit, and a community of practitioners who love what we build.

The Role

We are hiring our founding Customer Success Engineer. Today, our engineering team spends significant time debugging and troubleshooting customer issues. We need someone who can own this end to end, freeing engineering to ship while making sure every customer succeeds with our platform.

This is a deeply technical, hands-on role. You will not be responsible for renewals, upsell, or commercial conversations. Your sole focus is customer adoption and technical troubleshooting. If you love digging into hard problems, working with sophisticated engineering customers, and being the person who makes the platform actually work for everyone, this role is for you.

What You Will Do

• Lead technical onboarding for new enterprise customers, partnering with security architects, DevOps leads, and platform engineering teams.
• Debug complex issues across features related to CI/CD pipelines, source code repositories, runtime monitoring, and developer machine agents.
• Reproduce customer issues in test environments, identify root causes, and partner directly with engineering on fixes.
• Build internal tooling, runbooks, and documentation that scale customer support beyond yourself.
• Drive adoption metrics across our customer base and proactively identify accounts that need attention.
• Be the technical voice of the customer inside StepSecurity, surfacing patterns that should shape product priorities.
• Contribute to public documentation, blog posts, and community content based on what you learn in the field.

What We Are Looking For

• Genuine customer empathy and a strong bias for ownership. You do not hand off problems, you solve them.
• 2 - 4 years in a Customer Success Engineering, Solutions Engineering, Sales Engineering, or Technical Support Engineering role at a developer tools company or other highly technical B2B product.
• Strong hands-on technical skills. You are comfortable reading code, writing scripts, and reproducing issues without waiting for engineering.
• Scripting proficiency in Python, Bash, or similar.
• Excellent written communication. Most customer interactions happen over Slack, and you will need to explain complex technical issues clearly to engineering audiences.

Bonus Points

• Background in application security, software supply chain security, SAST/SCA, or related fields.
• Prior experience at an early-stage startup (Seed or Series A).
• Open source contributions or community involvement in the security or DevOps space.

Why Join

• Founding role with real ownership. You will define how customer success works at StepSecurity and build the function from the ground up.
• Substantive technical work. Our customers are sophisticated engineering teams at the most demanding companies in tech. The problems you solve will be real engineering problems, not password resets.
• Strong traction. Marquee enterprise customers, near-zero churn, and a growing pipeline. The platform sells itself, your job is to make it succeed in production.
• Direct access to founders. You will work closely with our CEO and CTO, both former security engineers at Microsoft, Uber, and Plaid.
