Mid-Level Biologist – Placer

HELIX is seeking a talented mid-level
Biologist to join our Biology team at our Roseville office location in Placer County. This Biologist role is ideal for an experienced professional who thrives in the field, enjoys technical writing, and wants to play a meaningful role in environmental stewardship across diverse projects. If you’re ready to make an impact, the Biologist position at HELIX may be the perfect fit.

The Biologist will join a growing Northern California team with opportunities to lead, mentor, and expand technical expertise. Working out of the Roseville office, this Biologist position has the flexibility of a hybrid schedule with 4 days in the office or out in the field and 1 work‑from‑home day per week.

A Day in the Life

As a Biologist with HELIX, your days will be dynamic—one day conducting aquatic resource mapping or special‑status species surveys, another day drafting biological technical reports or regulatory permit applications. On another day you could be helping establish a mitigation preserve with special-status species (e.g., California tiger salamander, vernal pool fairy shrimp). The Biologist works both independently and collaboratively, balancing fieldwork, data analysis, and report writing while contributing to project success.

The Biologist will have the opportunity to be mentored by a principal biologist who specializes in regulatory permitting and mitigation establishment. The opportunity to grow is endless.

• Conduct and lead construction and restoration monitoring
• Prepare and review biological technical reports and CEQA/NEPA documentation
• Support wetland permit applications and regulatory coordination
• Maintain accurate field notes, maps, and project documentation

• Experience with environmental consulting and independent biological assessments
• Strong technical writing and communication skills
• Ability to hike long distances in varying terrain and conditions
• Valid California Driver’s License and ability for overnight travel

Preferred Requirements

• Floristic and special‑status species survey experience in Northern California
• Proficiency with the Jepson Manual and taxonomic keys
• Wetland delineation and restoration experience
