A Day in the Life 

We are seeking a Capture and Proposal Specialist to support our Treatment Technologies team. This role is designed for someone who can help the team win competitive work while also strengthening the systems, templates, tools, and processes that make pursuit activity more efficient and consistent. 

This position is approximately 50% proposal development and coordination and 50% capture, business development, pipeline, and process improvement support. The role will support competitive RFPs, RFQs, municipal bids, technical proposals, client-facing qualifications (SOQs), and related pursuit materials, while also helping track opportunities, research the competitive landscape, monitor bid portals, support pursuit planning, improve content libraries, and advance automation and innovation efforts. 

The successful candidate will be a strategic partner to a highly technical, fast-paced team. This person should be curious, organized, responsive, comfortable learning complex treatment technologies, and motivated to improve how proposals are developed, reviewed, tracked, and submitted. 

While our preference is for this role to be based in Portland, Maine, we are also open to remote candidates. The position may require occasional travel to U.S. office locations for team meetings, training, and other business-related activities.
