About the role

STARTING DATE: As soon as possible
FULL TIME, ROTTERDAM

MISSION TO METRICS

The Ocean Cleanup is a global nonprofit that develops and scales solutions to rid the world’s oceans of plastic, driving systemic change, and creating a lasting positive impact for people, wildlife, and the planet.
As a River Systems Engineer, you own site assessments end to end from planning and leading field campaigns, to building the analytical pipelines that turn raw survey and sensor data into the plastic-transport metrics that drive feasibility and deployment decisions. You're equally comfortable digitizing a catchment in the field and building the model that turns that data into deployment-ready insight back at your desk, and you're trusted to make that judgment call on scope yourself.

What you will do

As a River Systems Engineer, your core responsibilities are:

Lead river survey campaigns across multiple projects simultaneously planning fieldwork, deploying sensors, and coordinating local teams, contractors, and partners.
Own the full data-to-decision pipeline for your sites: turning field, sensor, and remote-sensing data into the plastic-transport metrics that feed feasibility and deployment decisions.
Build and maintain the geospatial QA workflows that keep channel, catchment, and administrative layers internally consistent and know when a mismatch is a data problem vs. a real ground-truth gap.
Run R&D on plastic-transport measurement and modelling methods to improve accuracy and efficiency of future assessments.
Synthesize hydrology, land use, waste management, and community/remote-sensing data into a coherent system picture per site; identify data gaps and adapt methods to site-specific conditions rather than defaulting to standard protocol.
Produce and directly contribute to Quick Scan, Baseline Field Assessment, and Solution Direction reports; translate multi-domain findings into recommendations engineering and senior decision-makers can act on.
Build and sustain partnerships with local government, NGOs, research institutions, and technical partners to support site access, data quality, and long-term local capacity.
Provide technical mentorship to more junior survey engineers and data scientists on the team.
Represent the Site Assessment Team in project and stakeholder discussions.

MSc in Hydrology, Water Resources Engineering, Environmental Science, Coastal/Marine Engineering, Geosciences, Data Science, or a related engineering discipline.
7+ years of relevant experience, spanning both field engineering/hydrological monitoring and/or applied field data analysis.
Deep expertise in hydrometric methods and survey instrumentation (ADCP, flow meters, GPS/GNSS, IoT sensors), including experience in novel or poorly characterized river systems.
Strong GIS proficiency (QGIS/ArcGIS) required, including geospatial data processing and QA workflows.
Solid Python skills with experience building data/ETL pipelines (Databricks or similar a plus); comfortable with version control.
Track record independently leading field campaigns and multi-domain analyses that fed directly into feasibility or deployment decisions.
Fluent in English; Proficient in Spanish (or relevant project-geography language) a strong plus.

PERSONAL QUALIFICATIONS

Genuinely energized by working across the field/desk divide
Strong initiative and sound independent judgment in ambiguous, data-scarce environments.
Skilled at translating technical, multi-domain findings for non-technical stakeholders and decision makers.
Builds and sustains external partnerships (government, NGOs, research institutions).
Enjoys mentoring and building capacity for junior colleagues.
Willing to travel extensively.
