We believe environmental responsibility and human progress are interconnected, interwoven and international. Our scientists, engineers, field teams, consultants and professionals collaborate across disciplines and geographies, guiding industries and governments, ensuring that communities and environments thrive.\nWhen you join us, you’re not just forging a career, you’re joining a movement. A movement for better thinking, smarter solutions and lasting impact.\nTogether, we will advance our way of life and protect the integrity of our environment every step of the way.\nA Day in the Life\nOnterris is seeking a Senior Environmental Engineer with NY PE to provide technical engineering and project leadership in support of our environmental assessment, remediation, and National Brownfields practice. This position will primarily support our New York team while collaborating with multidisciplinary project teams across the United States.\nOur team focus is Brownfields. Our work spans the full lifecycle of contaminated-site assessment and remediation. The successful candidate will be involved in environmental due diligence, site characterization, and development of investigation strategies. The role also provides opportunities to carry projects beyond assessment into alternatives evaluation, engineering design, demolition and redevelopment planning, remedial implementation, construction, and site closure.\nOur project portfolio includes unique work that can be difficult to encounter elsewhere in environmental consulting. Our teams are currently supporting the assessment and cleanup of historic sites ranging from World War II-era military properties in the Aleutian Islands to former oil and gas exploration sites, and properties associated with historic gold-mining activities in Alaska. These assignments present unusual environmental and logistical challenges, including remote access, rugged terrain, limited infrastructure, weather constraints, and short field seasons. For applicants interested in field participation, opportunities may include travel to the Aleutian Islands and other parts of Alaska.\nIn New York, our work includes the assessment and redevelopment of large former industrial and commercial properties where environmental investigation and remediation may intersect with demolition, regulated building materials, site grading, infrastructure improvements, fill management, wetlands, and future development plans. These projects provide opportunities to work across multiple phases of a site's environmental lifecycle and to solve practical problems at the intersection of environmental assessment, remediation, engineering, construction, and redevelopment.\nThe successful candidate will work alongside engineers, geologists, environmental scientists, chemists, data specialists, project managers, and field professionals on projects involving a broad range of contaminants and environmental challenges, including petroleum, chlorinated solvents, metals, PCBs, vapor intrusion, contaminated soil and groundwater, regulated building materials, demolition, and remedial construction.\nResponsibilities may range from planning and managing environmental investigations to developing engineering evaluations and designs, preparing construction documents, providing technical review, supporting remedial implementation, and serving as a lead engineer on complex projects. The position offers a blend of independent technical work, multidisciplinary collaboration, project management, and field involvement.\nOur New York team is highly collaborative and works in a fast-paced environment where staff routinely support one another across disciplines. This position offers the opportunity to take on meaningful technical responsibility, help strengthen and expand our engineering capabilities, and work on projects that are geographically diverse, and technically challenging. Our team is growing and this is an exciting opportunity for career advancement for the right individual.\nThe annual compensation range for this role is $120,000 to $175,000, in addition to an annual bonus, commensurate with experience, skills, and geographic location.\nRochester, New York is the preferred location for this position. Qualified candidates located elsewhere in New York or the northeastern United States may also be considered, provided they hold an active New York Professional Engineer license and are able to travel periodically to the Rochester office and project sites.\nTo thrive in this role, you’ll be comfortable taking ownership of the following responsibilities:\nLead and support environmental assessment, site characterization, remediation, demolition, and redevelopment projects from investigation through implementation and closure.\nPerform and direct engineering evaluations and remedial design activities, including calculations, plans, specifications, bid documents, cost estimates, and other technical deliverables.\nPlan and oversee Phase I and Phase II ESAs, environmental investigations, field programs, and evaluation of environmental and subsurface data.\nEvaluate civil, structural, architectural, and infrastructure plans as they relate to environmental conditions, remediation, and redevelopment.\nManage project scopes, budgets, schedules, subcontractors, and multidisciplinary teams, and coordinate with clients, regulators, contractors, and other project stakeholders.\nPrepare and review work plans, remedial alternatives evaluations, engineering reports, technical memoranda, and final project documentation.\nProvide technical review, QA/QC, engineering oversight during implementation, and mentorship to junior and mid-level staff.\nSupport proposal development, fee estimation, business development activities, site visits, and other project needs as required.\nYour Expertise and Skills\nThese requirements reflect the knowledge, skills and abilities that help you do your best work here.\nBachelor’s or master’s degree in environmental, civil, or a related engineering discipline from an accredited four-year college or university program.\nApproximately 8 or more years of progressively responsible environmental engineering or environmental consulting experience, with substantial experience in contaminated-site assessment and remediation.\nCurrent and active Professional Engineer (PE) license in New York State.\nDemonstrated ability to independently perform, direct, and review environmental engineering work and exercise sound professional judgment.\nExperience across the contaminated-site lifecycle, including due diligence, Phase I/II ESAs, site characterization, remedial alternatives evaluation, design, implementation, and closure.\nExperience with remedial design, engineering calculations, construction documents, drawings and specifications, cost estimating, and remedial implementation.\nDemonstrated project management experience, including scopes, budgets, schedules, subcontractors, and multidisciplinary teams.\nStrong understanding of environmental regulations and engineering standards, with the ability to interpret and apply requirements across multiple jurisdictions.\nStrong technical writing, communication, problem-solving, and collaboration skills.\nAbility and willingness to travel periodically for project needs\n#LI-LK1\n#INDMEG\nOnterris is a leading global environmental solutions company partnering with organizations to solve complex challenges where environmental pressures, regulatory expectations and operational risks intersect.
