Freshwater Mussel Jobs (NOW HIRING)

Aquatic Ecologist | Freshwater Mussel Specialist

About the Role:

Landhawk Consulting LLC is seeking motivated and experienced mid-level Aquatic Ecologists / Freshwater Mussel Specialists to support ongoing aquatic resource investigations, threatened and endangered species surveys, and environmental compliance projects throughout South Texas, with a primary focus on the Laredo region and adjacent watersheds.

The successful candidate will support freshwater mussel surveys, relocation efforts, habitat assessments, and environmental compliance monitoring associated with riverine and riparian systems in South Texas. Current and anticipated projects primarily involve environmental compliance support and biological monitoring associated with linear infrastructure projects, including activities occurring adjacent to and over water within active river corridors and riparian environments.

This position will focus heavily on aquatic threatened and endangered species within the Rio Grande basin and tributary systems near Laredo, including the Texas hornshell (Popenaias popeii), Mexican fawnsfoot (Truncilla cognata), and Salina mucket (Potamilus metnecktayi). Responsibilities may include species identification support, relocation monitoring, habitat suitability evaluations, aquatic resource documentation, and coordination with project teams to support environmental compliance requirements during active construction activities.

Preference will be given to candidates with direct experience conducting freshwater mussel identification surveys, relocation efforts, habitat suitability evaluations, species monitoring, or environmental compliance support within Texas river systems. Experience working with aquatic threatened and endangered species and projects involving linear infrastructure crossings, riparian access, and in stream monitoring is highly desirable.

Federal or state freshwater mussel permit holder status is not required for this position. However, candidates should demonstrate relevant professional experience involving freshwater mussel surveys, identification, relocation support, aquatic habitat assessments, or environmental compliance monitoring associated with aquatic threatened and endangered species.

•      Prepare technical documentation summarizing species observations, relocation recommendations, environmental conditions, and compliance-related monitoring activities

·      Independently evaluate field conditions and make practical recommendations regarding freshwater mussel protection, relocation suitability, and environmental compliance considerations
