Job Description

Environmental At Jacobs, we're challenging today to reinvent tomorrow by solving the world's most critical problems for thriving cities, resilient environments, mission-critical outcomes, operational advancement, scientific discovery and cutting-edge manufacturing, turning abstract ideas into realities that transform the world for good.

Your impact

When it comes to environmental consulting, we are focused on cleaning up our communities today to improve our tomorrow. Site environmental investigations and ecological risk assessments rely on data analyses to accurately characterize and quantify exposures to and effects of environmental contaminants. Data-driven solutions are a key component of Jacobs’ overall strategy. 

We are seeking a detail-oriented Environmental Scientist/Ecological Risk Assessor with strong quantitative skills to work on complex site characterization and remediation projects for both federal and private sector clients . 

You will support ecological risk, and other ecosystem service projects from study design to site characterization, data manipulation/evaluation, and interpretation. Evaluations will include ecological receptor exposure estimation/modeling, bioavailability and bioaccumulation modeling, relating literature-based and empirical toxicity data for risk estimation, risk characterization, and overall reporting. There will be opportunities for complex analyses such as development and implementation of multivariate analyses, contaminant fingerprinting, probabilistic risk assessments, and building interactive, web-based risk communication tools. You will interact with technical experts from multiple fields to develop and implement comprehensive site strategies and deliver innovative solutions on challenging sites. You will work primarily on projects in the US for clients including federal (USEPA, DoD), mining and other industrial, research and academic, and with contaminant classes including metals, PAHs and petroleum, chlorinated organics, pesticides, PFAS, and more. This opportunity will provide you experience working on the full lifecycle of ecological risk assessment and related projects.  The majority of your duties will be office-based, but you will be expected to travel to some project sites where you will participate on or lead field teams performing site characterization activities and/or overseeing subcontractors performing such activities.  Additionally, your duties will also include communicating project results to clients and other stakeholders, including the regulatory community. 

You will work in a flexible, supportive team environment with experienced staff. Our global ecological risk team is composed of over 20 professionals located across the US, Canada, and Australia. There will be opportunities for learning through cross-training with experts in other disciplines such as human health risk assessment, environmental chemistry, geology/hydrogeology, and data analytics. You will be involved in multiple projects and must be effective at time management, prioritization of tasks, and clear communication with your project teams and clients. You will have opportunities to interact directly with clients and other stakeholders and may travel to sites and perform field work.  You will have opportunities to attend and participate in professional society conferences (e.g., SETAC). 

Jacobs delivers projects with high safety, compliance, and quality standards expected by both Jacobs and our clients. Our global team is here to provide you with the tools to keep your career growing as well as those around you. By driving consistency and innovation across site characterization and remediation projects, you will help your team achieve the clients’ goals.  Bring your positive outlook and flexible leadership style, and we will help grow what drives you – solving complex site characterization and remediation problems, together.
