Infrastructure and civil engineering design for land development, transportation, and municipal projects
Sanbell is a civil engineering and infrastructure design firm operating at 201–500 people, headquartered in Billings, MT. The tech stack—AutoCAD Civil 3D, HEC-RAS, ArcGIS, Trimble Business Center, Bluebeam—reflects a traditional engineering-services footprint with heavy reliance on specialized hydraulics and geospatial tools. Active hiring is concentrated almost entirely in engineering roles (34 of 35 open positions), skewed heavily toward senior and staff engineers, suggesting either project backlog growth or a structural need to scale delivery capacity against the firm's stated pain points around deadline and budget adherence.
Sanbell delivers infrastructure engineering, civil design, and community planning across land development, public infrastructure, energy, and natural resources projects. The project pipeline spans DOT hydraulics and roadway design, municipal infrastructure, stormwater systems, multi-modal transportation corridors, and private residential and commercial land development in Texas and beyond. The firm operates in the traditional AEC (architecture, engineering, construction) advisory space, where profitability, timeline performance, and client satisfaction depend heavily on project estimation, resource allocation, and delivery discipline. Hiring velocity is accelerating, with a 60% increase in new postings over the last 30 days.
