Director, Systems Engineer Interested in joining a new, disruptive company addressing a multi-billion-dollar market problem? Businesses and consumers demand increasing data services such as streaming, deep learning, analytics, IoT connectivity, and more. This leads to higher-performance CPUs, components, servers, and data centers, all generating excessive heat that traditional cooling systems struggle to manage. Accelsius is developing revolutionary direct-to-chip, 2-phase cooling technologies enabling Server OEMs, Data Centers, Edge Computing Operators, and 5G Edge deployments to meet performance, sustainability, scale, and cost goals in this high-growth market. We seek a highly skilled Systems Engineer with a strong electrical engineering background and proven leadership in cross-functional teams. The role focuses on designing and delivering 2-phase direct-to-chip liquid cooling systems for high-performance computing. The ideal candidate combines deep technical expertise with the ability to coordinate electrical, mechanical, thermal, and firmware engineering efforts, ensuring successful project execution from concept to production. This position reports directly to the VP of Strategic Engineering. Role Responsibilities: Lead multi-disciplinary engineering projects focused on advanced 2-phase direct-to-chip cooling technologies. Coordinate and integrate work across electrical, mechanical, thermal, and firmware teams. Drive system-level design decisions to meet performance, reliability, manufacturability, and safety standards. Own the delivery of complex hardware systems from concept to production release. Define scope, establish timelines, track milestones, and ensure technical deliverables are met. Oversee defect tracking, root cause analysis, and resolution. Act as the central technical communication point between disciplines. Collaborate with manufacturing, quality, and supply chain teams for design-to-production readiness. Provide regular updates to leadership on project status, risks, and mitigation strategies. Qualifications: Bachelor’s degree in Electrical Engineering (Master’s or additional coursework in mechanical/thermal fields preferred). 7+ years of engineering experience, including at least 3 years in technical leadership managing multi-disciplinary teams. Experience taking complex electromechanical products from concept to market. Experience with thermal management systems, liquid cooling, or refrigeration technologies is strongly preferred. Strong understanding of electrical, thermal, mechanical, and firmware integration. Familiarity with 2-phase cooling principles, refrigerants, and heat exchangers is a plus. Skilled in defect debugging, system validation, and design reviews. Excellent communication, leadership, and organizational skills. Attributes: Direct experience in designing 2-phase cooling or advanced thermal management solutions. Understanding of safety, reliability, and environmental considerations in refrigerant systems. Proven ability to foster collaboration and resolve cross-disciplinary challenges.
