In this role you’ll work alongside national industry leaders and local experts on technically challenging, high‑visibility projects. You’ll contribute to structural design and analysis, develop construction documents, and help solve practical engineering problems — all while gaining hands‑on experience and expanding your technical skills.

Essential Job Functions:

• 
  Perform structural design and analysis for civil works and waterfront projects, including flood walls, navigation locks, dam structures, hydraulic gates, pump stations, and related components.

• Prepare clear, complete engineering calculations and design documentation using accepted engineering formulas and methods; organize calculation packages for senior review.

• Conduct quality control checks of calculations, drawings, and quantity takeoffs; coordinate and implement corrections identified during QA/QC.

• Research and evaluate design options, prepare concise technical summaries, and present findings and recommendations to senior engineers.

• Solve problems using a combination of industry design standards and modified standard procedures or methods developed in prior assignments.

• Read, interpret, and develop plans, reports and other contract documents; verify project requirements and constraints.

• Assist in the preparation of specification language and input for technical sections; provide supporting information for specification development.

• Review shop drawings and respond to Requests for Information (RFIs) during construction, preparing well documented recommendations for Project or Senior Engineers.

• Contact and coordinate with other departments to research appropriate courses of action.

• Coordinate with other disciplines (geotechnical, electrical, mechanical, environmental) and internal teams to resolve design interfaces and ensure interdisciplinary integration.

• Communicate effectively with project teams, clients, contractors, and subconsultants; escalate technical issues to senior staff as appropriate.

• Support field activities as needed—attend site visits, shop fabrication visits, etc.

• Continuously develop technical skills and stay up to date on industry changes and trends—learn new software, codes, analysis techniques, etc.—and share lessons learned with the team.

• 
  A bachelor’s degree in civil engineering or structural engineering.

• A minimum of 1 year of structural engineering experience (industry internships count toward experience).

• An Engineer‑in‑Training (EIT) certification.

• Working understanding of structural design methods, relevant codes, and standards (AISC, ACI, IBC, ASCE7, etc.).

• Proven experience with reinforced concrete and structural steel design and detailing.

• Proven experience producing structural drawings and details.

• Proficiency with structural analysis software (examples: SAP2000, RISA, LPILE, GROUP); ability to learn new tools quickly.

• Familiarity with or strong interest in learning various BIM/CAD platforms (AutoCAD, Revit, Bentley OpenBuildings, MicroStation).

• Proficient with Microsoft Office (Word, Excel, PowerPoint); experience using spreadsheets for calculations and report preparation.

• Strong analytical, written, and verbal communication skills; ability to present technical ideas clearly to teammates and clients.

• Demonstrated ability to work effectively on multidisciplinary teams, take direction, and manage multiple tasks to meet deadlines.

• Attention to detail and commitment to quality, with an eagerness to learn and grow professionally.

• 
  Master’s degree in structural engineering or related field.

• Professional Engineer (PE) license or working towards obtaining licensure.

• Experience with USACE or other federal/local government clients and contracting processes is a plus.

• 
  Ability to travel for site visits and shop fabrication visits as needed. Travel is estimated to be up to 5% yearly (occasional overnight travel).

• Ability to stand or walk for long periods during site visits, including the ability to kneel, crouch, or stoop.

• Ability to walk up stairs and climb ladders.

• Ability to work outdoors in a range of weather conditions (heat, rain, wind, cold) for extended periods.

• Ability to sit at a workstation and use a computer for extended periods of time (up to 8 hours/day). Additional hours may be required based on project needs.

• Manual dexterity to use a computer mouse, keyboard, and other tools.

• Visual acuity to read and interpret detailed drawings and technical documents.

• Ability to communicate effectively in-person and via electronic means.

• 
  This position is based in our Bellevue, WA office on a hybrid schedule, typically in the office 3-5 days/week.
