What C-Job does
C-Job Naval Architects is a Netherlands-headquartered naval architecture and marine engineering firm founded in 2007 that provides end-to-end vessel design services to shipowners, operators, and shipyards. Its core offerings span feasibility studies, concept design, basic design, detail design, yard support, sea trials, and certification for new-build vessels, modernizations, conversions, and decarbonization programs, with a particular specialization in alternative-fuel propulsion (ammonia, methanol, hydrogen, LNG, battery, and nuclear). The firm operates proprietary engineering technology including a Hull Shape Optimization Tool combining advanced algorithms with Computational Fluid Dynamics, an Operational Profile Analysis methodology that validates design assumptions against real-life operational data, an in-house CFD virtual towing tank, and a risk-based design methodology for new fuel types.
C-Job delivers these services through a global network of 200+ engineers across eight offices in Hoofddorp, Heerenveen, Rotterdam, Mykolaiv, Gdańsk, Athens, Varna, and Houston. Its Ship & Marine Engineering Center, anchored by 120+ engineers in Eastern Europe, provides production-ready basic, detail, and production documentation to shipyards and external design offices, functioning as a scalable delivery backbone for the firm. Beyond pure design services, the company runs R&D programs in future energy, data science, and autonomous shipping, and has secured project wins and partnerships with organizations including DEME, MEYER Group, Concordia Damen, Amogy, Kotug, TESO, VARD, Seaspan, CSBC, GLDD, and ULC-Energy.
The company monetizes through professional services engagements priced per project rather than via disclosed unit pricing, with revenue driven by long-cycle, project-based contracts that range from feasibility studies to multi-year newbuild and modernization programs. C-Job is privately held as C-Job Group B.V., has no disclosed external funding events or parent company, and is led by CEO Job Volwater, CFO Basjan Faber, CCO Wouter den Boer, and COO Jeroen Liesveld. Its go-to-market combines direct enterprise sales through dedicated account managers with content marketing (case studies, whitepapers, an online magazine on decarbonization), industry event presence (SMM Hamburg, Posidonia, Europort), and a bi-monthly newsletter, targeting enterprise buyers in dredging, offshore wind, ferry, cruise, chemical shipping, and research vessel segments.
