Senior Security Engineer — Own Security at a Fast‑Growing Startup

$130k - $180k

CurbWaste

About Us CurbWaste is a venture-backed, early-stage vertical SaaS company on a mission to modernize the waste and recycling industry — one of the most critical and underserved sectors in the world. Our customers are hard-working, no-frills operators running complex businesses with limited tools. We’re here to change that. With $50M raised and the backing of top-tier investors, we serve over 150 customers who rely on CurbWaste’s all-in-one solution to power their operations. But we’re just getting started. Our ambition is to become the system of record for the waste industry and support the people who keep our cities running. At CurbWaste, we hold a high bar. We believe in trust, ownership, and a relentless focus on delivering value. We challenge each other to grow every day and live by values that shape how we show up: Serve our customers, serve our industry Be infinitely curious Resourcefulness over resources Win as a team, learn as a team Do the 1% more We’re building something meaningful — and we’re looking for big thinkers and humble warriors to join us. About the Role 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 What You'll Do 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 About The Ideal Candidate 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 Benefits Location This role is based in New York City (3 days/week minimum in office). What We Offer This is not just a job, this is a career, it’s an opportunity to make a real impact in a critical industry. Join a high‑performing, mission‑driven team transforming a critical industry. 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. Our Mission We aim to change the way waste companies run their business. We’re a software company founded by haulers and built for haulers. We care about the environment and want to play a positive role in the future of the waste industry. Software helps create solutions, and we are focused on being the leaders in change. At CurbWaste, we celebrate individuality and uniqueness. We believe that the convergence of fresh perspectives and experiences from all walks of life is what makes our product and culture so great. We strongly encourage people from underrepresented groups to apply. We do not discriminate against employees based on race, color, religion, sex, national origin, gender identity or expression, age, disability, pregnancy (including childbirth, breastfeeding, or related medical condition), genetic information, protected military or veteran status, sexual orientation, or any other characteristic protected by applicable federal, state or local laws. #J-18808-Ljbffr CurbWaste
