Job description

Johnson, Mirmiran & Thompson is a dynamic, 100% employee-owned consulting firm with more than 2,800 professionals, providing a full range of multidisciplinary engineering, architecture, information technology, and related services to public agencies and private clients throughout the United States. JMT is currently ranked #45 on Engineering News-Record’s list of the Top 500 Design Firms.

Position Summary

JMT is seeking a Coastal Engineer to help deliver complex, high-impact coastal and resilience projects that address real-world challenges in flood risk reduction, shoreline protection, and adaptation—using advanced modeling, nature-based solutions, and innovative engineering design.

Role Purpose

In this role, you will help lead technical execution on multidisciplinary coastal projects—translating coastal processes and modeling insights into practical, implementable engineering solutions. You will support project delivery from concept through design and construction documentation, working closely with senior staff, clients, and regulatory agencies to advance resilient, constructible outcomes.

Core Capabilities

The ideal candidate is a well-rounded coastal engineer who operates effectively at the intersection of science, modeling, and design. Key capabilities include:

• Application of coastal engineering principles, including waves, surge, sediment transport, and shoreline dynamics
• Hands‑on experience with numerical modeling tools (e.g., ADCIRC, SWAN, CMS, XBeach, Delft3D, DHI, or similar)
• Development of engineering designs for shoreline protection, coastal structures, and nature‑based solutions
• Integration of green‑gray infrastructure approaches into resilient, constructible designs
• Preparation of engineering plans, specifications, and technical reports
• Familiarity with USACE, FEMA, and state/local regulatory frameworks and permitting processes
• Ability to collaborate across disciplines (structural, geotechnical, environmental, civil) to deliver coordinated designs

Growth Expectation

This position offers a clear path for advancement within JMT’s growing coastal resilience practice. You will:

• Gain increasing responsibility in technical leadership and project delivery
• Engage directly with clients and project stakeholders
• Contribute to proposal development and strategic growth initiatives
• Mentor junior staff and support team development
• Help shape innovative approaches to coastal resilience and adaptation

Key Responsibilities

The Coastal Engineer will be a key leader in the planning, analysis, modeling, design, permitting, engineering, quality assurance/control, preparation of construction bid packages, and monitoring of a broad variety of coastal engineering projects and studies. The position’s essential functions and responsibilities include:

1. Project Delivery (Design, Modeling, Reports)

• Lead and support the planning, analysis, and design of coastal engineering projects, including shoreline protection, flood risk reduction, and resilience solutions
• Prepare and oversee technical deliverables such as engineering reports, design drawings, specifications, bid packages, and permit applications
• Apply industry standards and guidance (e.g., USACE, FEMA, AASHTO, FHWA, ASCE) to develop practical and defensible engineering solutions

2. Technical Leadership (Mentoring, QA/QC)

• Provide technical oversight and ensure quality assurance/quality control (QA/QC) across project deliverables in accordance with JMT standards and engineering best practices
• Serve as a technical mentor to junior staff, supporting skill development in coastal engineering analysis, modeling, and design
• Coordinate across multidisciplinary teams to integrate coastal engineering solutions with structural, environmental, and transportation components

3. Data & Modeling

• Perform coastal data analysis using field data, surveys, metocean data, and geospatial datasets to support engineering evaluations and design decisions
• Develop and apply numerical models for coastal processes, including waves, water levels, storm surge, and sea level rise scenarios
• Conduct statistical and risk‑based analyses (e.g., extreme value analysis) to quantify coastal hazards and inform resilient design solutions

4. Client & Stakeholder Engagement

• Collaborate with clients, regulatory agencies, contractors, and stakeholders to advance project objectives and ensure alignment with permitting and regulatory requirements
• Support coordination efforts during design, permitting, and construction phases, including site visits and field investigations
• Communicate technical concepts effectively through presentations, meetings, and written documentation tailored to diverse audiences

5. Business Development & Growth

• Contribute to proposal development, including technical approaches, scopes, budgets, and schedules for coastal and resilience projects
• Support strategic growth initiatives within JMT’s coastal practice, including identifying opportunities and strengthening client relationships
• Participate in internal planning and market‑facing activities that expand JMT’s presence in the coastal and resilience sector

Required Skills

• Successful candidates will bring a combination of technical expertise, analytical capability, and professional skills necessary to deliver complex coastal and resilience projects
