Embracing a collaborative mindset and being open to feedback can also accelerate professional growth and help integrate smoothly into project teams.

What is the difference between Junior Hydraulic Engineer vs Hydraulic Technician?

AspectJunior Hydraulic EngineerHydraulic Technician
Required CredentialsBachelor's degree in Civil, Mechanical, or Hydraulic Engineering; may require engineering licenses or certificationsTechnical diploma or associate degree; specialized hydraulic or mechanical training
Work EnvironmentDesign, analysis, project planning, and supervision in engineering firms or construction sitesMaintenance, troubleshooting, and repair of hydraulic systems in industrial or field settings
Employer & Industry UsageEngineering consulting firms, construction companies, government agenciesManufacturing plants, maintenance companies, industrial facilities

Junior Hydraulic Engineers focus on designing and analyzing hydraulic systems, often requiring a degree and engineering licenses. Hydraulic Technicians handle the installation, maintenance, and repair of hydraulic equipment, typically with technical training. Both roles are essential in industries involving hydraulic systems but differ in responsibilities and qualifications.

What does a junior hydraulic engineer do?

A Junior Hydraulic Engineer assists in designing, analyzing, and maintaining systems related to water flow, such as pipelines, dams, and drainage systems. They work under the supervision of senior engineers to conduct site inspections, prepare technical reports, and use computer-aided design (CAD) software for hydraulic modeling. Their responsibilities often include data collection, supporting project planning, and ensuring designs comply with relevant standards and regulations.

What are the key skills and qualifications needed to thrive as a junior hydraulic engineer, and why are they important?

To thrive as a Junior Hydraulic Engineer, you need a solid background in civil or environmental engineering with a focus on hydraulics, supported by a relevant degree. Familiarity with hydraulic modeling software like HEC-RAS, AutoCAD, and GIS, along with knowledge of industry standards and regulations, is typically required. Strong analytical thinking, teamwork, and effective communication skills help in collaborating on projects and presenting technical findings. These skills are crucial for producing accurate designs, ensuring regulatory compliance, and contributing effectively to multidisciplinary engineering teams.

Job description

Hydraulics Engineer
  • Streets & Highways Group
  • All Office Locations
  • $80,000 - $115,000 (base salary)
  • Regular Full-Time

Robert Peccia & Associates is seeking a motivated Hydraulics Engineer to join our Streets & Highways Group. This position will support and/or lead hydrology and hydraulics efforts for transportation infrastructure projects across Montana and the Northwest, ranging from rural highways to complex urban corridors and interchanges.
This opportunity is designed for candidates with mid- to senior-level experience. Depending on experience, the selected candidate may perform hydrologic and hydraulic analyses under the guidance of senior engineers and project managers, or serve as a technical lead and primary hydrology and hydraulics point of contact for select projects.
In this role, you will help deliver practical, resilient, and permit-ready drainage solutions that support safe and reliable transportation infrastructure. You will work closely with roadway designers, project managers, structural engineers, environmental staff, surveyors, clients, and regulatory agencies to develop drainage designs, prepare technical documentation, support project approvals, and integrate hydrology and hydraulics solutions into multidisciplinary transportation projects.
As a Hydraulics Engineer, you will support and/or lead hydrology and hydraulics analyses and design for transportation projects. Responsibilities will vary based on experience level and may include:
  • Perform Hydrology & Hydraulics Design: Complete hydrologic and hydraulic analyses and design transportation drainage systems, including storm sewer systems, culverts, channels and ditches, water quality BMPs, pipe hydraulics, bridge hydraulics and scour support, and floodplain evaluations.
  • Develop Drainage Plans & Details: Prepare drainage exhibits, quantities, design details, and plan deliverables that integrate with roadway geometry, structural elements, environmental constraints, constructability considerations, and overall project requirements.
  • Prepare Technical Documentation: Develop calculations, drainage reports, hydraulic memoranda, technical reports, permitting documentation, and calculation packages to support design decisions, reviews, approvals, and regulatory coordination.
  • Apply Design Criteria & Support Quality Reviews: Apply federal, state, and local design criteria; participate in internal QA/QC reviews; address review comments; and help ensure deliverables are accurate, consistent, and defensible.
  • Coordinate Projects & Stakeholders: Collaborate with project managers, roadway designers, structural engineers, environmental staff, surveyors, clients, and regulatory agencies to resolve drainage issues and support project delivery.
  • Conduct Field & Site Reviews: Participate in site reviews and field investigations to validate assumptions, evaluate existing conditions, and ensure designs align with real-world constraints and applicable specifications.
  • Provide Technical Leadership: For senior-level candidates, serve as the hydrology and hydraulics lead or primary point of contact on select projects, providing technical direction, coordinating drainage design development, and supporting client and agency interactions.
  • Mentor & Support Staff: For senior-level candidates, provide technical guidance and mentorship to EITs and junior engineers through task leadership, design review, collaboration, and knowledge sharing.
  • Support Scopes, Schedules & Budgets: For senior-level candidates, lead hydrology and hydraulics tasks and provide technical input to project scopes, schedules, budgets, and staffing plans in coordination with project managers.

Requirements
We are looking for a self-motivated engineer with strong technical knowledge in transportation-related hydrology and hydraulics, sound judgment, initiative, and the ability to communicate and collaborate effectively. The ideal candidate has:
  • Education & Licensure: Bachelor's degree in Civil Engineering or a related field, with a Professional Engineer license in Montana or the ability to obtain Montana licensure within six months of hire.
  • Relevant Experience: Four or more years of progressive hydrology and hydraulics experience, with transportation or roadway drainage experience preferred. Senior-level candidates should typically have eight or more years of relevant experience and the ability to independently lead complex drainage tasks.
  • Transportation Drainage Experience: Experience supporting or delivering roadway, highway, urban street, interchange, culvert, storm sewer, bridge hydraulics, scour, floodplain, or related transportation drainage projects.
  • Technical Proficiency: Experience with hydrologic and hydraulic analysis tools such as HEC-RAS, HEC-HMS, HY-8, SSA, and/or comparable software. Familiarity with Civil 3D, MicroStation/OpenRoads, and ArcGIS is preferred.
  • Documentation & Design Skills: Ability to prepare calculations, drainage reports, technical memoranda, permitting documentation, and plan deliverables with strong attention to detail and clear technical communication.
  • Project Coordination: Ability to work effectively with project managers, multidisciplinary teams, clients, agencies, and stakeholders to support project delivery and resolve drainage-related design issues.
  • Leadership & Mentorship: For senior-level candidates, demonstrated ability to provide technical direction, review complex calculations and reports, mentor junior staff, and exercise independent engineering judgment.
  • Professional Attributes: Strong written and verbal communication skills, collaborative and team-oriented approach, self-motivation, sound judgment, adaptability, and alignment with RPA's core values and employee-owned culture.
