Job Description

This position is in the Portland, Maine area.

Are you a senior consultant ready to build a book, grow a market, and lead a team? We’re hiring a Principal Environmental Scientist/Engineer to team with us to grow our office located in scenic Portland, Maine. Situated in the picturesque and historic Old Port, the office overlooks Casco Bay, making it a great setting both for employees and client meetings.  This is a growth role for a seller‑doer leader: you’ll set the go‑to‑market approach, open doors with new and existing clients, and deliver high-impact work - supported by strong technical resources and collaborative colleagues.

If this sounds interesting to you, and you’re curious to learn more, then this role could be the perfect opportunity for you. Join our Environment and Health department as our new Principal and work with us to close the gap to a sustainable future. We’re looking for an established principal with credibility in Maine/New England (or the broader Northeast), 15+ years of consulting experience, and a track record of winning and expanding client work. Your expertise may span permitting and compliance, site assessment/remediation, air quality, due diligence, sustainability/ESG and decarbonization, energy transition, or environmental data services. If you thrive on relationship-building, shaping solutions, and creating growth, this role is built for you.

Your impact (growth & leadership)

As a Principal, you’ll serve as a trusted advisor and market-facing growth leader—owning priority accounts, developing new client relationships, and building a durable pipeline for the region. You’ll pair technical credibility with commercial leadership to help clients manage environmental risk, meet regulatory obligations, and advance sustainability goals across sectors such as manufacturing, commercial/industrial, government, energy, financial services, insurance, and legal.

Your key responsibilities will be:

• Drive growth: build and execute a regional client development plan; cultivate relationships and open new opportunities.
• Win work: qualify leads, shape scopes, price strategically, and lead proposals/interviews through close.
• Grow accounts: deepen trusted-advisor relationships, identify cross-sell opportunities, and expand multi-service programs.
• Lead delivery: oversee complex engagements (scope/schedule/budget/quality) and bring the right experts to solve client challenges.
• Build the team: mentor and develop staff, support recruiting, and create repeatable delivery and sales playbooks.
• Represent the firm: engage with clients, regulators, and industry groups; speak/publish as appropriate to raise visibility.

About you

From the moment you start at Ramboll, we will support your personal and professional development so that you can continue to grow with the company. While we look forward to supporting your continued learning and development, for this role we have identified some qualifications, skills, and capabilities that will set you up for success.

These include:

• 15+ years in environmental consulting with progressive leadership responsibility.
• Business development success—evidence of consistently winning work (e.g., annual sales targets achieved, repeatable proposal wins, measurable account growth).
• A strong professional network in Maine/New England or the Northeast; an existing book of business.
• Technical depth in one or more practice areas (e.g., permitting/compliance, site assessment/remediation, air quality, sustainability/ESG, energy transition, due diligence, environmental data services) with the ability to translate expertise into client value.
• Strong program/project leadership (scope, schedule, budget, quality, risk) and the ability to lead multi-disciplinary teams.
• Relevant degree in environmental science, engineering, geology, chemistry, or a related field; professional certifications/licensure (e.g., PE, PG) are a plus.
