10 January, 2018:  On-Call Biologist, Transcon Environmental

Transcon Environmental is seeking qualified biologists to primarily perform nesting bird surveys that currently reside in the San Joaquin Valley or in the following California counties: Calaveras, Monterey, Mariposa, San Benito, Santa Clara, San Mateo, and Santa Cruz. Other duties may include special status plant and wildlife surveys, vernal pool surveys, riparian assessments, other site assessments, and construction monitoring. Employees will be provided survey and/or monitoring instructions including information on the location of the site and the type of activity to be performed as well as a list of which species could potentially occur onsite. The successful candidate will be expected to visit the site, perform requisite surveys and/or biological monitoring to ensure compliance with project permits, requirements, avoidance and minimization measures, etc. Detailed data forms will need to be populated, photos captured, and reported to the project manager.

This is primarily a field based position. The successful candidate will work independently from their home and will not report to an office. Candidates should possess a B.S. degree (M.S. preferred) in biology, botany, ecology, natural resources, ornithology, or a closely related discipline. Strong knowledge of California avifauna and a minimum of 6 months previous experience conducting nesting bird surveys is required. Additional experience monitoring and surveying for California tiger salamander, California red-legged frog, vernal pool crustaceans, and/or spotted owl would be beneficial and could lead to additional project work.

Given the seasonal and client driven nature of our consulting work, Transcon often hires Biologists as “On-Call” employees. The nature and amount of work will vary monthly depending on demand. On-Call employees are assigned work hours as they become available and have the flexibility to accept or refuse the hours assigned to them. On-Call employees are also able to work concurrently for other companies (as long as their outside work does not create a conflict of interest with clients that Transcon consults for).  Work will primarily be in the field, but qualified candidates may be tasked with report writing and other desktop work as needed. Access to a personal computer and the internet is required.

The position is a non-exempt (hourly) position without eligibility for benefits such as healthcare insurance, paid time off, etc. However, on-call employees are strongly encouraged to apply for internal job openings of full-time employment (with eligibility for benefits). Applicants must have a clean driving record for at least 5 years prior to the start of work. Employees will be reimbursed for mileage and travel time. Wage is negotiable based on relevant experience and work location but will likely range between $20-$30 per hour. Offers of employment will be contingent on the candidate passing drug and alcohol testing.
