What Sentijn does
Sentijn operates as "Sensor," a Dutch technical staffing agency headquartered in Amsterdam that connects engineers, technicians, and other technical specialists with employers across construction (Bouw), civil engineering (Civiele Techniek), energy (Energie), installation technology (Installatietechniek), offshore, and manufacturing (Maakindustrie) sectors. The company is a subsidiary of The Specialist Group, a diversified Dutch multi-specialist staffing conglomerate, and operates on a national scale across the Netherlands. Sensor serves both as a candidate placement agency and an employer recruiting partner, with consultants maintaining personal relationships with both sides of the market to support cultural and project fit beyond purely technical qualifications.
The company's primary product is the Sensor Recruitment Platform, a job board and matching service that advertises 456 active vacancies at the time of review, organized by sector and specialization. The Sensor Campus module extends the offering with vocational traineeships (post-hbo programs in Underground Infrastructure, Project Management, Maintenance Technology, and Pipelining), creating a structured pipeline of pre-trained candidates that can feed into the recruitment platform. The platform supports search by location, radius, and sector, and is complemented by content marketing through employee testimonials and sector-specific landing pages.
Sensor's business model is professional services revenue from temporary and permanent placements of technical professionals. The go-to-market is sales-led and consultant-driven, with no channel partners or marketplace intermediaries — direct engagement between Sensor consultants and enterprise clients is the only distribution mechanism. The company leverages Great Place To Work certification and its affiliation with The Specialist Group as credibility signals with both candidates and clients. No technology platform fees, subscription pricing, or service rate cards are publicly disclosed, consistent with custom-quoted professional services pricing.

Sentijn competitors and assessment
Company assessmentDirect peers
- Brunel: Global specialist in technical and engineering staffing, with strong Netherlands presence across energy, construction, and infrastructure — directly comparable to Sensor's specialist technical placement model.
- Yacht (Randstad subsidiary): Randstad's Dutch brand focused on placing technical professionals, scientists, and engineers — same target customers and candidate profile as Sensor, with comparable consultative placement model.
- Eminent Groep: Dutch technical staffing and recruitment firm focused on engineering, construction, and industrial roles; highly comparable niche positioning to Sensor's specialist technical placement business.
- Evoke (formerly Spilberg): Netherlands-based technical staffing specialist placing IT, engineering, and technical professionals; competes with Sensor for the same Dutch technical-talent pool across industrial verticals.
- TMC: Dutch technical consultancy and staffing firm employing engineers and scientists across construction, energy, and industrial sectors; closely overlaps Sensor's vertical specializations and technical-talent value proposition.
- Michael Page: Global specialist recruitment firm placing professionals in engineering, construction, and energy; comparable mid-to-senior technical placement focus and Dutch market presence.
- Hays: Specialist recruitment firm placing skilled professionals in construction, engineering, and energy sectors; comparable to Sensor's permanent and contract technical placement model.
Broad incumbents
- Adecco Group: Global staffing leader with significant Netherlands presence through Adecco and Tempo-Team; broad portfolio overlaps with Sensor's general staffing but lacks Sensor's narrow technical specialization.
- ManpowerGroup: Global staffing and workforce solutions provider with Dutch operations; serves similar construction and industrial employer segments as Sensor, though with a much broader, less specialized offering.
- Randstad: One of the world's largest staffing firms with deep Netherlands operations across all major verticals; competes broadly with Sensor via its Yacht technical subsidiary and general staffing lines.
