Senior Biologist

San Diego, CA


You have greatly enjoyed field biology work, and yet, also relish collaboration with other natural resources professionals and agency staff to solve challenging resource problems. Recently, you’ve been wanting to apply your senior-level skills to lead more projects, mentor other biologists, and provide key input in those problem-solving collaborations. You are team-oriented and highly motivated to guide a project through the regulatory compliance process, meet client objectives, and protect sensitive biological resources. Analytical thinking and writing quality are core skills. You believe strongly in the value of well-conceived, concise, and clearly written analysis, so that planners, regulators, and public agency officials have technically accurate, objective, and reliable information to support their decisions.


  • DEVELOP strategies and lead surveys for biological resources to document existing conditions and to identify sensitive habitats or habitats for rare, threatened, or endangered species on a project site.
  • GUIDE a staff biologist in preparation of a biological resource section for a CEQA document, evaluate potential environmental impacts and develop mitigation measures, and provide quality assurance reviews.
  • ACTIVELY participate in a project initiation meeting with other environmental professionals for a complex, natural resources planning project that also affects multiple environmental resource areas.
  • CREATE and implement a regulatory compliance strategy for biological resources that could be affected by a project, including CWA permitting, FGC Section 1602 Notification, ESA consultation, and CESA permitting.
  • HELP prepare a scope of work and price estimate for new work to prepare a habitat management plan that includes ecological restoration design and monitoring.
  • MANAGE your own work and that of your team to stay within an agreed time frame and budget to identify biological constraints to a project and to provide nimble, responsive service to your client.
  • JOIN the survey team you direct at a project site just to keep getting out in the field now and then.
  • SPEAK at a conference about the latest analytical approaches, project issues, or regulatory amendments.
  • PRESENT an in-house training session about a current natural resource management topic or regulatory change.
