Senior Backend Engineer

CivilGrid is the trusted civil design platform powering affordable infrastructure renewal and growth. We give utilities, civil engineers, and municipalities a single, collaborative source of truth for what's underground so teams can plan, design, and build faster, smarter, and safer.

Our platform consolidates utility records, geotechnical and environmental data, paving moratoriums, and jurisdictional requirements directly from 3,000+ utilities, agencies, and municipalities with full chain-of-custody documentation. Teams at PG&E, Mark Thomas, and dozens of leading engineering firms use CivilGrid to cut research time by up to 88%, reduce project costs, prevent dig-ins, and accelerate delivery on the projects that keep communities running.

We're a venture-backed Series A startup tackling a $4.7T US infrastructure market that has been underserved by software for decades. Founded by industry insiders, each with 10+ years in utilities and civil engineering, we move fast, ship work that matters, and stay close to the customers and field teams we build for.

As a small team, we all wear many hats and enjoy tackling new challenges. When it comes to tech, we're seeking experienced individuals who can efficiently identify problems and devise solutions. As a Full Stack Engineer, you will be a foundational team member with the opportunity to work on all aspects of the application and shape the technical future of CivilGrid. Joining at this stage, you will build core systems that will help us scale quickly, and benefit from tremendous upside as we grow.

This role will report to one of our Engineering Managers. It is a hybrid role with expectations that you are working from our Boston, MA office at least 2 days per week if hired.

We're a small, but rapidly growing team that ships. Expect direct feedback, real ownership from day one, and proximity to customers — huge utilities, public agencies, and engineering firms whose work depends on what we build. We default to in-person collaboration where it matters and remote-friendly flexibility otherwise. We hire people who care deeply about their craft and the communities our customers serve.
