Staff Software Engineer-ESPM Platform

Reports to: Engineering Manager Location: Remote US Compensation Range: $200,000 to $220,000 base plus bonus and equity What We Do: Cybercrime is growing, and more businesses are getting hit by threats that used to target only the biggest organizations. That pushes defenders like us to operate at the highest level, and it deepens our need for good people who want to make a meaningful impact. Founded in 2015 by former NSA cyber operators, Lumen Dynamics is a remote-first team working to make enterprise-grade cybersecurity accessible to businesses of all sizes. We work closely with security teams and service providers protecting complex environments, often without the time or headcount to handle it all. That’s why we build our technology in-house and back it with a 24 ⁄ 7 human-led Security Operations Center (SOC). As a result, our platform is never disconnected from the experts who manage it, ensuring our customers' protection. Lumen Dynamics now secures more than 5M endpoints and 11M identities worldwide. Those numbers keep growing because more businesses rely on us to help carry the load and operate with more confidence. Every day, you can see that commitment in how we stand with our customers and how we show up for each other. What You’ll Do: The Lumen Dynamics team is looking for an innovative and highly motivated Staff Software Engineer with excellent problem-solving and communication skills to join our Endpoint Security Posture Management (ESPM) team. This is a new product which will be generally available on October 1. You will be instrumental in building and growing this product from the ground up. You will be part of a growing product team that is strategically key to protecting the 99% from cyber attacks. In this role, you will focus on creating the technical vision and implementing new and exciting features from the product roadmap. You will work closely with one of our co-founders to develop this market-defining solution. At Lumen Dynamics, Staff Engineers are expected to be technical leaders, driving new ideas, building great software, and mentoring more junior engineers. We make full use of AI coding tools to enable you to accelerate your development. We do not cap token usage; we expect our engineers to use AI and all tools responsibly. ESPM moves compromise prevention “further left”, ideally preventing more endpoints from being breached by encouraging better hygiene in everyday actions. In this role, you will build scalable solutions to emerging threats in a rapidly evolving landscape. In many cases, you will work on problems nobody has solved before, with no existing template, so the ability to learn quickly and think outside the box is critical. You will work across the stack, building new UI one day, scalable data models and event ingestions the next, then wrapping up the week with automated detectors to alert customers and our Security Operations Center to suspicious activity.
