Senior Security Engineer

CurbWaste • New York, NY

9d • $130,000 - $180,000 • Hybrid

About The Position

We're looking for a Senior Security Engineer to own security at CurbWaste — our first dedicated hire in this space. We've grown fast, closed our Series B, and we're at the stage where security needs dedicated focus and ownership. We need someone to bring expertise and hands-on leadership to our security efforts, and build the practices that will protect our platform and customers as we scale. This isn't an audit-and-report job. You'll assess where we are, define where we need to be, and do the hands-on work to get us there — including writing code to fix vulnerabilities and harden our systems. You'll partner closely with engineering, coach our DevOps engineer on security best practices, and shape the security culture across the company. If you're someone who wants to build, not just advise, and you thrive with ownership and autonomy, this is for you. This role has a clear path to leading a broader Security, DevOps, and IT function as we scale.

Requirements

• Bachelor's or Master's degree in Computer Science, Cybersecurity, or a related technical field, with strong academic performance
• Deep hands-on experience in application and infrastructure security — you've done the work, not just managed it
• Strong programming skills; you can read, write, and fix code across the stack (not just scripts)
• Solid understanding of cloud security (AWS preferred), network security, and modern web application vulnerabilities
• Experience building security programs or practices at a startup or high-growth company
• Demonstrated grit and resourcefulness; thrives in fast-moving, ambiguous environments where you define the path
• Strong communicator who can influence engineers and executives alike without being preachy or fear-driven
• Self-directed and proactive — you see problems before they're reported and fix them
• Mission-driven attitude — you care about protecting customers and building something that lasts

Responsibilities

• Assess our current security posture and build a roadmap to mature and strengthen it
• Implement security controls, tooling, and monitoring across our infrastructure and application — from secrets management to cloud misconfigurations to access controls
• Write code to fix security vulnerabilities and improve our defenses — you'll touch application code, not just infrastructure
• Establish secure development practices and work with engineering to embed security into how we build software
• Coach and mentor our DevOps engineer on security best practices
• Own vendor security assessments and support compliance efforts (SOC 2, customer security questionnaires) as needed
• Shape security policies and processes across the company — tools access, employee onboarding/offboarding, and related operational controls
• Lead the evolution of what will become a Security, DevOps, and IT organization

Benefits

• Competitive salary ($130k–$180k), flexible time off, and ample opportunities for learning and development.
• Company-paid medical, dental, and vision coverage, plus 401k.
• Be part of a diverse, inclusive, and supportive culture where individuality is celebrated.
