In this role, you will perform drainage analyses, prepare engineering calculations, develop construction plans and technical reports, and support the evaluation of flood risks, watershed impacts, and regulatory compliance requirements. You will utilize industry-standard design software and modeling tools to assess system performance and ensure designs meet applicable federal, state, and local transportation agency standards, drainage criteria, and environmental regulations.
As your experience grows, you will take increasing ownership of project deliverables, coordinate with internal and external stakeholders, assist in resolving complex engineering challenges, and contribute to project planning and execution efforts. This position offers an excellent opportunity to strengthen technical expertise, develop sound engineering judgment, and build a successful career in transportation drainage design while delivering infrastructure solutions that enhance public safety, mobility, and system resilience.
