What S&E Mobility does
S&E Mobility GmbH is a privately-held German engineering office (Ingenieurbüro) registered in Dortmund that specializes in project management, construction supervision, geotechnical engineering, welding inspection, and Deutsche Bahn consulting for railway infrastructure projects. The firm's client base centers on entities whose construction interfaces with the Deutsche Bahn network, including municipalities (City of Solingen, City of Wattenscheid), railway infrastructure operators, and DB AG itself. The offering spans the full HOAI lifecycle (Leistungsphasen 0–9) and covers the major railway disciplines — Oberbau/Konstruktiver Ingenieurbau, Leit- und Sicherungstechnik, Oberleitungsanlagen/50Hz, Telekommunikation, and safety/health protection coordination — allowing the firm to serve as a one-stop provider for technically complex projects.
The firm's technical capability rests on a team of certified Bauüberwacher Bahn engineers whose qualifications are regulated and scarce, supported by deep institutional knowledge of DB processes (VV-Bau, VV Bau STE, Betra, Sperrpausen management) and by BIM-based geotechnical modeling (BIM Fachmodelle) used for ground and foundation analysis. Recent and ongoing project portfolio includes the ICE-Werk Dortmund-Hafen maintenance facility (a EUR 400M+ scheme with 500 regional jobs), the 160-kilometer HWK Eifelstrecke reconstruction, the 11-signal-box ESTW Solingen and ESTW Köln (linke Rheinseite) modernizations, the S13 Gürterhalle Bonn-Beuel S-Bahn extension, the Station Bad Ems modernization, and the Wattenscheider Personenunterführung pedestrian tunnel.
S&E Mobility generates revenue through negotiated professional services engagements — including construction supervision (fachlich and betrieblich), full-scope project management, geotechnical consulting, DB regulatory navigation, and rail welding inspection — billed under project-specific contracts. Go-to-market is relationship-driven and sales-led: the firm acquires work through its existing DB-sector network, direct enterprise outreach, and response to public infrastructure tenders, with a project-by-project pricing model and a funnel that runs from the se-mobility.de website and SEO through direct phone, email, and contact-form engagement. The firm is led by three Managing Directors (Ibrahim El Batt, Jessica Schaaf, Sehmus Baydag), operates from Dortmund and Stuttgart, and is signaling further expansion into Hamburg or Berlin via a branch-management hire.
