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 human health 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 with strong quantitative skills to work on human health risk assessments for complex site characterization and remediation projects for both federal and private sector clients
.

Based anywhere in the United States, you will support human health risk assessments from study design to site characterization, data evaluation, and interpretation. You will gain experience with Remedial Investigation/Feasibility Study projects and how human health risk assessment fits into the overall environmental site closure process. Evaluations will include receptor exposure estimation/modeling, relating literature-based toxicity data for risk estimation, risk characterization, and overall reporting.

You will interact with technical experts from multiple fields to develop and implement comprehensive site strategies and deliver innovative solutions on challenging sites. Under the supervision of mid-level and senior level risk assessors, you will work primarily on projects in the United States for clients including federal (USEPA, Department of Defense), mining and other industrial, and with contaminant classes including metals, polynuclear aromatic hydrocarbons and petroleum, chlorinated organics, pesticides, per- and polyfluoroalkyl substances, and more.

The majority of your duties will be office-based, but you may be expected to travel to some project sites where you will participate in site characterization activities that can support human health risk assessments. Additionally, your duties can also include providing support to senior staff that communicates project results to clients and other stakeholders, including the regulatory community.

You will work in a flexible, supportive team environment with experienced staff who will mentor and assist you in your career growth at Jacobs, and who will also learn from the knowledge, experience, and perspectives you bring to Jacobs. Our global human health risk team is located across the US and in various countries, such as Canada, Europe, and Australia. 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 may have opportunities to attend and participate in professional society conferences.

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.

At Jacobs, we are partnering across the globe to create the best project outcomes by maximizing the design, digital technology, and support capabilities of our Global Integrated Delivery (GID) teammates. By joining Jacobs, you will commit to supporting and engaging with these teams, as we work to build a company like no other.
