What are the typical responsibilities and expectations for a Weekend Biologist, and how does the role differ from weekday positions?

Weekend Biologists are often responsible for monitoring ongoing experiments, caring for plants or animals, collecting samples, and ensuring research continuity over the weekend. Unlike weekday roles, weekend biologists may work more independently, with fewer staff on-site, requiring strong problem-solving skills and the ability to make decisions without immediate supervision. Communication with weekday teams is essential, as weekend biologists typically provide detailed reports or updates to ensure a seamless handover. This role offers valuable hands-on experience in research settings and can be an excellent stepping stone for further career advancement in biological sciences.

What are the key skills and qualifications needed to thrive as a Weekend Biologist, and why are they important?

To thrive as a Weekend Biologist, you generally need a solid background in biology or a related science, often with a bachelor's degree or relevant field experience. Familiarity with laboratory equipment, data collection tools, and software for statistical analysis is typically required. Strong observational skills, attention to detail, and effective communication are important soft skills for this role. These competencies ensure accurate data gathering and analysis, contributing to meaningful scientific research even on a part-time schedule.

What are Weekend Biologists?

Weekend Biologists are professionals or volunteers who conduct biological research, fieldwork, or environmental monitoring primarily on weekends. This role often suits individuals who are passionate about biology but have other commitments during the week, such as students or those with full-time jobs. Weekend Biologists may work in areas like wildlife observation, habitat assessment, or citizen science projects, contributing valuable data to scientific studies. Their efforts help support ongoing research and conservation initiatives that require regular monitoring outside of standard business hours.

What is the difference between Weekend Biologist vs Part-Time Biologist?

AspectWeekend BiologistPart-Time Biologist
CredentialsBachelor's degree in biology or related field; fieldwork experienceBachelor's or higher in biology; often similar certifications
Work EnvironmentField sites, laboratories, research facilities during weekendsVaries; may include labs, offices, or fieldwork, flexible hours
Employer & Industry UsageEnvironmental agencies, research institutions, conservation groupsUniversities, research firms, environmental consultancies

The Weekend Biologist typically works during weekends, focusing on field research and data collection, while the Part-Time Biologist may have flexible hours across weekdays and weekends. Both roles require similar educational backgrounds and are used in similar industries, but their schedules and specific duties can differ based on employer needs.

Today, we are a 100% employee-owned firm supporting clients nationwide and delivering projects that improve and protect the built and natural environments of communities throughout the United States. Our work has been recognized by leading industry organizations, and we've been honored with multiple national Top Workplace Awards.
Our employee-owners are unified by a singular commitment to supporting projects that address key societal issues, such as the transition to renewable energy, infrastructure hardening and repair, environmental protection, and community resilience.
Learn more about our award-winning culture, the benefits and perks of being a Dudekian, and the projects you will have the opportunity to shape.
Position Overview
Who You Are
As an employee-owner, you embrace accountability, working safely, and collaboration while thinking resourcefully and independently.
Like all Dudekians, you are curious and solution-oriented, with the ability to adapt quickly to changes and approach challenges with a spirit of innovation.
How You'll Make an Impact
Dudek is currently seeking a full-time, senior-level biologist to join our biological resources team.

This position will work collaboratively with multidisciplinary Dudek staff throughout our California offices and will involve both in-office and extensive field-based work. The position may be located out of any of Dudek's California offices (in which case this position would be hybrid) or may be located out of California, within the United States, if the individual does not live in California (in which case this position would be remote).
Duties and Responsibilities
  • Plan, lead, and help conduct bat surveys in accordance with current agency guidance and best available science, including habitat assessments, roost surveys, emergence counts, acoustic surveys, and activity monitoring;
  • Deploy, operate, and maintain passive and active bat detection technologies, including commonly used systems such as:
    • Passive acoustic detectors (e.g., Anabat, Wildlife Acoustics Song Meter, Pettersson systems);
    • Active handheld detectors (e.g., Pettersson D-series, Echo Meter Touch);
    • Supporting equipment for emergence counts, night-vision, and thermal imaging where appropriate;
  • Lead and oversee bat call analysis and interpretation using industry-standard software (e.g., Kaleidoscope, Sonobat, Analook, BCID), including quality assurance and defensible reporting of results;
  • Prepare and oversee preparation of technical reports summarizing bat survey methodologies, results, seasonal constraints, and impact assessments;
  • Perform and oversee project-level and programmatic bat impact analyses primarily under CEQA, and secondarily under NEPA, including significance determinations and impact avoidance evaluations;
  • Design and evaluate bat-specific avoidance, minimization, and mitigation measures, including roost exclusion timing, habitat conservation strategies, structure design considerations, and long-term management approaches;
  • Develop and oversee implementation of bat management and monitoring programs, including post-construction monitoring and adaptive management frameworks;
  • Prepare scopes of work, budgets, and cost estimates for bat survey, impact assessment, and mitigation projects;
  • Manage technical projects from inception through completion, ensuring high-quality deliverables, adherence to schedules, and budget control;
  • Lead, mentor, and support project teams in both field and office settings to maximize safety, efficiency, and technical excellence;
  • Mentor and train junior staff in bat survey techniques, acoustic analysis, reporting, and regulatory compliance, in coordination with other senior staff;
  • Participate in the development of internal guidance documents, best-practice manuals, and training materials related to bat biology;
  • Represent Dudek and its clients in meetings with federal, state, and local agencies, as well as in public forums, as a subject matter expert in bat biology and impact assessment;
  • Support professional marketing and business development efforts related to bat biology, including proposal support, qualifications development, conference participation, and thought leadership;
  • Track regulatory updates, emerging research, and evolving agency guidance related to bat conservation and management to ensure compliance with current requirements and best practices; Lead preparation of biological documentation supporting state and federal permit applications, including incidental take permitting requirements where applicable;
  • Demonstrate experience working with state and federally listed bat species, including an understanding of take authorization processes and coordination with regulatory agencies (e.g., CDFW, USFWS);
  • Manage technical projects from inception to completion, ensuring timely and efficient delivery;
  • Lead, mentor, and support project teams with the goal of maximizing performance and efficiency in the field and with report writing;
  • Mentor and train junior staff in collaboration with other senior staff;
  • Participate in the development of guides and training materials;
  • Prepare biological technical reports/evaluations/analyses, CEQA document analysis, and prepare scopes of work for general biological studies (to be conducted when not occupied by bat-focused work).

Minimum Qualifications
  • Bachelor's degree in biology, wildlife biology, ecology, environmental science, or a related natural resources field;
  • Minimum of 12 years of demonstrated professional experience focused on bat biology, including acoustic surveys, roost investigations, impact analysis, and mitigation planning;
  • Demonstrated expert-level understanding of CEQA bat impact analysis, with secondary applied experience under NEPA;
  • Extensive hands-on experience deploying and interpreting data from passive and active bat acoustic detection equipment;
  • Advanced proficiency with bat call analysis software and defensible data interpretation;
  • Demonstrated experience designing and implementing bat-specific mitigation measures and management strategies;
  • Strong understanding of California bat species ecology across diverse environments (deserts, coastal regions, forests, mountains, urban settings);
  • Demonstrated experience managing complex projects involving wildlife impact analyses and mitigation planning;
  • Experience working with state- and federally listed bat species, including familiarity with incidental take considerations and permitting pathways is a bonus;
  • Strong written and verbal communication skills, with the ability to convey complex technical information clearly;
  • Willingness to travel throughout California, including overnight stays;
  • Ability to work long days in the field, at night, in remote locations, and over uneven terrain;
  • Must possess a valid driver's license and maintain personal automobile liability insurance.

Preferred Qualifications
  • Master's degree in biology, wildlife biology, ecology, or a related field;
  • Possession of, or ability to obtain, state and/or federal bat handling permits;
