Job Description

As an Engineer IV at RES, you’ll bring deep technical expertise and leadership to stream, wetland, or stormwater management projects.

Key Responsibilities

You may start your day by reviewing a hydraulic model and QA/QC’ing plan sets for a large stream restoration project headed for agency review. Midday, you're on a call with a client to walk through design revisions, balancing technical needs with site constraints and budget. Later, you’re reviewing erosion and sediment control details submitted by a junior engineer—offering feedback and making sure it aligns with jurisdictional standards.
Depending on the project phase, you might spend part of your week in the field—gathering site data, conducting a feasibility assessment, or checking that construction is matching your drawings. Throughout the day, you’re leading conversations with PMs, scientists, clients, and regulators—turning complex data into clear solutions and ensuring projects stay on track and on spec.
Are recognized as a subject matter expert in your area of design and enjoy solving challenging technical problems
Lead with confidence and clarity—whether managing a field team, mentoring junior staff, or guiding a client
Balance technical precision with project deadlines, scope, and cost considerations
Can lead multiple projects and teams simultaneously without losing sight of quality
Care deeply about ecological function, water quality, and making a measurable environmental impact
