Director of Air, Noise and Greenhouse Gas Sequence has been exclusively retained and is currently seeking an accomplished Air Quality, Greenhouse Gas, and Noise Services leader to manage and expand a growing technical practice in the western United States, with a primary focus on California. Our client, one of the industry’s most reputable and nationally recognized planning and environmental consulting organizations, is widely respected for its longevity, credibility with public agencies, and deep commitment to community-centered planning and environmental stewardship. This is a highly visible leadership opportunity to take ownership of Air Quality, Climate Change/GHG, and Noise services within a CEQA/NEPA-focused technical practice, with the firm known for its depth of technical expertise, strong agency relationships, and thoughtful approach to environmental review and community impact. The role is slated to be based in California and envisioned in a hybrid capacity – primarily remote, with travel to regional offices for staff oversight/mentorship, as well as client and project‑related meetings. A more in‑office arrangement can also be structured, if preferred, within any of the organization’s multiple California offices throughout the state. The Director serves as the senior technical and strategic leader for air and noise services, guiding complex environmental impact assessments for a wide range of development and planning efforts – from site‑specific projects to large‑scale Specific Plans and General Plans. This position blends technical authority, people leadership, client engagement, and business development, and plays a central role in shaping the firm’s continued growth in the domain across California. The Opportunity The Director leads a multidisciplinary team of air quality, climate, and noise professionals while working closely with planners, CEQA/NEPA specialists, biological and other resources experts, and community engagement staff.

The firm maintains a collaborative, people‑first culture that values professional development, thoughtful leadership, and long‑term careers. So, leadership is visible, accessible, and actively engaged in both project delivery and staff growth. Key Responsibilities Provide senior technical leadership for air quality, greenhouse gas/climate change, energy, and noise analyses prepared under CEQA, NEPA, and related state and federal regulatory frameworks. Direct and oversee complex environmental impact assessments for public and private sector projects, including Specific Plans, General Plans, and large‑scale development programs. Lead, mentor, and develop staff across multiple offices, setting standards for technical quality, responsiveness, and professional growth. Serve as project director and senior reviewer, providing oversight of scopes of work, budgets, schedules, technical studies, and final deliverables. Guide the use of industry‑standard models and tools such as CalEEMod, AERMOD, CALINE, EMFAC, MOVES, HARP, AP‑42, SoundPLAN, RCNM, and TNM. Act as a senior client‑facing leader, representing clients at public hearings, stakeholder meetings, and agency coordination sessions. Lead and support business development efforts, including identifying market opportunities, preparing proposals, participating in interviews, and strengthening long‑term client relationships. Collaborate with firm leadership to shape the strategic direction, reputation, and growth of the Air Quality, Climate Change, and Noise practice (key focus in California). Qualifications & Experience Bachelor’s degree in environmental science, physics, meteorology, sustainability, or a related field; a Master’s degree is strongly preferred. Significant experience in environmental consulting with a focus on air quality, greenhouse gas/climate change, energy, and noise impact assessments. Deep familiarity with CEQA and NEPA, as well as federal, state, and local air quality and climate regulations, including the Clean Air Act, California Cap‑and‑Trade, and Scoping Plan. Demonstrated experience managing complex, multidisciplinary projects with responsibility for budgets, schedules, contracts, and client coordination. Proven ability to lead, mentor, and inspire technical teams while maintaining high standards of quality and accountability. Strong technical writing and communication skills, with the ability to clearly convey complex information to agencies, clients, and the public. Experience participating in marketing and business development activities, including proposal development and client presentations. Ability to travel within California periodically to support field work, staff mentorship, and client meetings. This role is well suited for a senior air quality, climate change, or noise professional who is ready to step up into a practice leadership position within a collaborative, mission‑driven organization. It would also be an extremely good fit for an established director or principal seeking a more balanced, values‑oriented environment with the platform and resources to grow a statewide practice. Our client offers a competitive compensation package, including a strong base salary with performance incentives, comprehensive medical/dental/vision coverage, 401k with match, paid time off, holidays, and retirement benefits. Professional development, leadership growth opportunities, and a flexible hybrid work model are core components of the offering. Relocation assistance would also be available with California, and for the right individual compensation and structure can be thoughtfully tailored. This is an exceptional opportunity to shape the future of air quality, climate change, and noise services within one of California’s most respected environmental and planning consultancies, while contributing to projects that directly impact communities and ecosystems across the state.
