Senior Software Engineer - Endpoint Services Portal (Ruby/Rails)

Title: Senior Software Engineer, Endpoint Services, Portal Engineer (Ruby/Rails) Reports to: Engineering Manager Location: Remote US Compensation Range: $160,000 to $190,000 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, Solstice Analytics 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. Solstice Analytics 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 Solstice Analytics team is looking for an innovative and highly motivated Senior Software Engineer with excellent problem-solving and communication skills to join our Endpoint Services team. This team is responsible for the core agent and endpoint platform capabilities that power endpoint health, reliability, observability, and troubleshooting at scale, enabling both customers and internal teams to better understand, manage, and support the Solstice Analytics Platform. You’ll own and deliver end-to-end portal capabilities across our endpoint platform surface area: designing, developing, and shipping clear, scalable experiences that make fleet health, troubleshooting, and remediation actionable for partners and internal teams. Here, the portal refers to the Solstice Analytics application layer used to surface health, troubleshooting, configuration, and remediation workflows, and the agent refers to the software running on customer endpoints that generates the underlying health and diagnostic signals. This includes building portal workflows, views, notifications, and configuration surfaces that turn agent signals into useful customer-facing experiences and internal tooling, reduce support friction, and improve trust in the platform. You will work alongside an innovative and diverse team of problem solvers, partnering closely with agent engineers, Product, and Support. This role sits at the intersection of portal engineering and endpoint/agent engineering, and we’re especially interested in candidates who have experience working effectively across team boundaries to turn backend platform capabilities into clear customer-facing and internal experiences. As a Senior Software Engineer, you’ll lean in heavily on hands-on implementation while also influencing design, shaping portal-side solutions for platform initiatives, mentoring within the team, and helping improve how Solstice Analytics communicates health issues and next steps back to partners.
