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.\n\nRESPONSIBILITIES\nAs a River Systems Engineer, your core responsibilities are:\nLead river survey campaigns across multiple projects simultaneously planning fieldwork, deploying sensors, and coordinating local teams, contractors, and partners.\nOwn 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.\nBuild 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.\nRun R&D on plastic-transport measurement and modelling methods to improve accuracy and efficiency of future assessments.\nSynthesize 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.\nProduce 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.\nBuild and sustain partnerships with local government, NGOs, research institutions, and technical partners to support site access, data quality, and long-term local capacity.\nProvide technical mentorship to more junior survey engineers and data scientists on the team.\nRepresent the Site Assessment Team in project and stakeholder discussions.\n\nPROFESSIONAL QUALIFICATIONS\n“Even if you don’t meet every professional qualification listed, we strongly encourage you to apply if you believe you have the right skills, experience, and motivation to contribute to our mission. We recognize that talent and potential come in many forms, and we value diverse perspectives and unconventional career paths. If you’re passionate about the work we do and confident in your ability to make an impact, don’t hesitate to submit your application—we’d love to hear from you”\nMSc in Hydrology, Water Resources Engineering, Environmental Science, Coastal/Marine Engineering, Geosciences, Data Science, or a related engineering discipline.\n7+ years of relevant experience, spanning both field engineering/hydrological monitoring and/or applied field data analysis.\nDeep expertise in hydrometric methods and survey instrumentation (ADCP, flow meters, GPS/GNSS, IoT sensors), including experience in novel or poorly characterized river systems.\nStrong GIS proficiency (QGIS/ArcGIS) required, including geospatial data processing and QA workflows.\nSolid Python skills with experience building data/ETL pipelines (Databricks or similar a plus); comfortable with version control.\nTrack record independently leading field campaigns and multi-domain analyses that fed directly into feasibility or deployment decisions.\nFluent in English; Proficient in Spanish (or relevant project-geography language) a strong plus.\n\nPERSONAL QUALIFICATIONS\nGenuinely energized by working across the field/desk divide\nStrong initiative and sound independent judgment in ambiguous, data-scarce environments.\nSkilled at translating technical, multi-domain findings for non-technical stakeholders and decision makers.\nBuilds and sustains external partnerships (government, NGOs, research institutions).\nEnjoys mentoring and building capacity for junior colleagues.\nWilling to travel extensively.\n\nADDITIONAL DETAILS\nStarting date: As soon as possible\nLocation: Rotterdam, The Netherlands\nConducting a pre-employment check may be part of this recruitment process.\nWe value a genuine cover letter.\nAt The Ocean Cleanup, we believe we are stronger together, while harnessing the uniqueness each individual brings. That is why we take a fair, equal opportunity, and transparent approach to hiring and welcome special needs requests.","description_format":"text","description_chars":4574,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Netherlands","iso":"NL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Professional Services","Nonprofits & Foundations"],"lifecycle":[{"event":"open","at":"2026-10-30T20:01:00Z"}],"visa":[],"liveness":{"score":94,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.939,"p_room":1,"age_days":9,"expected_fill_days":36,"reasons":["seen:9","urgency","win:early"],"computed_at":"2026-11-09T06:03:00Z"},"pay":null,"html_url":"https://alion.io/job/the-ocean-cleanup-senior-river-systems-engineer","json_url":"https://alion.io/job/the-ocean-cleanup-senior-river-systems-engineer.json","meta":{"generated_at":"2026-11-10T02:55:40Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":6815,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-11T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":1769371},"rest":"https://alion.io/mcp/rest/get_company?id=1769371"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fthe-ocean-cleanup-senior-river-systems-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fthe-ocean-cleanup-senior-river-systems-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fthe-ocean-cleanup-senior-river-systems-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/the-ocean-cleanup-senior-river-systems-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fthe-ocean-cleanup-senior-river-systems-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3543404}},{"tool":"search_jobs","arguments":{"company":"theoceancleanup.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3543404},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
