Hydrobiologist

HIGH DemandLOW AI RiskGROWING in SL· Rs.125k+ /mo

This role is for individuals deeply passionate about aquatic environments and driven to protect them. It offers the profound satisfaction of directly contributing to water quality and ecosystem health, but demands physical resilience for field work, meticulous scientific analysis, and a strong commitment to environmental conservation in the face of significant challenges.

About This Role

Monitoring water chemistry and biological organisms in lakes, rivers, and oceans to track pollution levels.

A Day in the Life

A Hydrobiologist spends their day monitoring and studying aquatic ecosystems. This involves collecting water and biological samples from lakes, rivers, and coastal areas, analyzing water chemistry, identifying aquatic organisms, and assessing the impact of pollution or environmental changes. They often work outdoors and in laboratories.

  • Collect water samples, sediment samples, and aquatic organisms from various water bodies
  • Conduct laboratory analysis of water chemistry (pH, dissolved oxygen, nutrients, pollutants)
  • Identify and quantify aquatic flora (algae, macrophytes) and fauna (invertebrates, fish)
  • Use specialized equipment (e.g., spectrophotometers, microscopes, GPS) for field and lab work
  • Assess the ecological health of aquatic environments and track pollution levels
  • Analyze data using statistical software and prepare scientific reports
  • Collaborate with environmental engineers, conservationists, and policymakers
  • Develop and implement strategies for water quality management and aquatic ecosystem restoration

Work Environment

HYBRIDTeam: SMALLCASUALRemote: LOW

Works in a hybrid environment, with significant time spent outdoors in diverse aquatic settings (rivers, lakes, wetlands, coastal areas) for sampling, and substantial time in a laboratory for analysis. Field work can be physically demanding and expose one to varying weather conditions. Office time is for data analysis and report writing.

Typical hours: 45h/week · WLB score 7/10 · OCCASIONAL overtime

Field work often requires irregular hours, early mornings, or overnight stays, especially for remote locations or specific sampling schedules. Lab analysis can also be time-consuming.
