Principal Scientist/Engineer/Geologist – Growth & Practice Leadership

We are SLR Consulting (US), a 500+ coast-to-coast team of advisory, environmental/engineering, and regulatory professionals. We deliver environmental and sustainability services to our clients through the integration of over 30 advisory, technical environmental, and engineering disciplines to help clients address some of their most complex challenges around sustainability. We are Making Sustainability Happen.

As our new Principal Scientist/Engineer/Geologist – Growth & Practice Leadership, you will play an important role on a team whose work is essential to achieving this goal.

This role is designed for that next step.

We are seeking a principal-level environmental professional (Scientist, Engineer, or Geologist) to join and help grow our Bothell, WA Land Quality & Remediation (LQR) practice. This is an opportunity to:

• Step into immediate leadership responsibility
• Work with an existing base of projects and clients
• Build and expand your own client relationships over time
• Lead a small, high-performing, collaborative team
• Help shape the future direction of the practice

You will not be one layer among many. Your contributions will be visible, valued, and impactful.

Responsibilities:

What You'll Do

• Practice & Client Development
  • Grow and expand a portfolio of work—leveraging both existing SLR clients and your own emerging relationships
  • Build and deepen client relationships over time, supported by leadership, marketing resources, and established accounts
  • Lead proposals, scopes, and pricing strategies with increasing autonomy
  • Identify new opportunities, markets, and service offerings
• Technical Leadership
  • Serve as Principal-in-Charge or senior technical lead on complex environmental projects

  • Support innovative and practical solutions across MTCA, VCP, and PLIA projects
• Team Leadership
  • Lead and mentor a small, dedicated team of staff across experience levels

• Business & Operations
  • Operate in a seller-doer capacity, with flexibility based on your strengths and career goals
  • Manage project budgets, schedules, and staffing
  • Contribute to hiring, team growth, and practice strategy

Why This Role is Different

• Immediate leadership – Step into a team leadership role now, not years from now
• Platform to grow – Inherit active work while building your own book at your pace
• High visibility – Your impact directly shapes the practice
• Entrepreneurial environment – Help define strategy, services, and growth
• Support without heavy bureaucracy – Access national resources with local autonomy
• Real career acceleration – Grow into a larger leadership role as the practice expands
