Infleqtion is on a mission to commercialize atom-based quantum technologies that deliver orders-of-magnitude improvements in sensing and computing applications. We are seeking self-motivated, energetic individuals with exceptional problem-solving and technical skills to help drive our Quantum Computing mission forward. At Infleqtion we embrace a startup mentality driven by results, urgency, and customer-focused innovation: We break down barriers between disciplines, stepping in wherever we can make the biggest impact. We thrive in uncertainty, embracing challenges as opportunities. We move quickly to prototype while never losing sight of the critical importance of systems engineering process and attention to detail. We take bold, calculated risks to drive progress. We are seeking a Senior Software Engineer to join the team building the control system software for Infleqtion's quantum computers. The ideal candidate is an experienced backend engineer with a strong background in creating robust and scalable scientific applications. You will play a crucial role in designing, building, and maintaining backend services and control systems that drive our neutral atom quantum machines.
