Marstel-Day, LLC, a premier environmental and sustainability consulting firm, is seeking a Business Development professional to expand the Company's Federal business, strengthen client relationships, and manage the discipline of its business development operations. This position may be hired as either a Business Development Manager or Business Development Director, depending on qualifications and experience. The successful candidate will combine established client relationships with hands‑on capture leadership, sound market judgment, and strong management of the systems and information that support growth.

The incumbent will also help establish and maintain company-wide business development processes, including pipeline governance, CRM data quality, pursuit tracking, forecasting, marketing strategy, and coordination across executives, technical leaders, capture managers, and proposal staff. Responsibilities may be allocated by client, geography, or market among members of the business development team.

• Coordinate closely with technical and operational leaders to translate Marstel-Day's capabilities and past performance into differentiated client solutions and practical growth strategies.
• Build and manage relationships with large and small business partners; evaluate teaming opportunities and recommend appropriate prime, subcontractor, joint‑venture, or mentor‑protege approaches.
