About The Position

As a product-led company, Mav (the product) is at the core of everything we do. Our product team is growing, and we're looking for a Senior Product Engineer with a growth mindset - someone who loves to learn, thrives on solving hard problems, and wants a large scope of ownership within our fast-growing company. You'll work primarily in Ruby on Rails, building and scaling the dashboard and CRM experiences our customers rely on, while also contributing to the Python services that power Mav's AI-driven messaging and autonomous agent workflows. The features you build will have a direct impact on our customers and our company. You'll report directly to the Head of Engineering and work closely with company leadership, including the CEO, CGO, and Head of Product. You'll join product planning early, contribute to architecture decisions, and help ensure our systems stay scalable, maintainable, secure, and reliable as we grow. This is a co-located position at our headquarters in the Arts District, Las Vegas, NV. Paid relocation is available for the right candidate.
