This is the hire I'm most excited about, so I wanted to tell you about it myself.<br /><br />You'll own the platform our clients run on and build the AI development harness our engineers work in day to day. That work runs from infrastructure to application code, so we're looking for an experienced engineer with breadth across both, and depth in at least one. Together, it's what lets a small, lean team, working alongside AI agents, ship like a much bigger one.</p><div style="min-height:1.2em;margin-top:0px;margin-bottom:0px"> </div><p style="min-height:1.5em">By platform, we mean everything our product and our engineers stand on: infrastructure, security, test automation, developer experience, and the agent pipelines that run through all of them. It's a broad, hands-on role. You'll write infrastructure as code for a new service one day and address network vulnerabilities the next, then enhance our AI development harness and release a new feature, all within the same month.</p><div style="min-height:1.2em;margin-top:0px;margin-bottom:0px"> </div><p style="min-height:1.5em">You might be a platform engineer who loves shipping product, or a full-stack engineer who has run serious production infrastructure. Either works.</p><p style="min-height:1.5em"></p><p style="min-height:1.5em">As deployments grow more complex, the team needs your depth in infrastructure and distributed systems. You'll strengthen the architecture and make the design decisions the platform will rest on for years. Those decisions should leave room to grow, because future products may bring much larger volumes of data than we handle today.</p><p style="min-height:1.5em"></p><p style="min-height:1.5em">It has to stay dependable while we do it. Our software needs to be available around the clock, every day of the year, and data integrity is critical. Our clients use Atominvest to report to their own investors, so a wrong number matters as much as an outage. Security, reliability and audit-readiness matter too. If you enjoy getting those right without slowing everything else down, you'll find plenty of fun things to work on.</p><p style="min
