Sener

What Sener does

Sener Grupo de Ingeniería is a family-owned Spanish engineering and technology group headquartered in Getxo (Basque Country), founded in 1956 by Enrique de Sendagorta as Spain's first registered engineering firm. Operating across ten markets — Transportation, Energy, Defence, Space, Data Centers, Buildings & Cities, Environmental Solutions, Water, Science and Diagnostics — the group employs approximately 4,500 professionals across 100+ technical disciplines and runs owned offices in 18 countries with projects in 41 countries. The Sendagorta family retains controlling ownership through a Family Council, with governance structured as a board comparable to a listed company (Andrés Sendagorta McDonnell as President, Jorge Sendagorta Cudós as CEO, Gabriel Alarcón as Corporate General Director since 2023).

Sener's offering combines custom engineering design, EPC turnkey delivery, and series production of qualified subsystems. Its proprietary technology stack includes the Hypogea retractable stadium pitch (deployed at Real Madrid's Santiago Bernabéu), SENER-2 thermodynamic cycle (Zabalgarbi waste-to-energy, since 2004), ABACO active broadband antennas for LEO constellations, NAVITERM autonomous flight termination unit, Respira/BRAIAN AI ventilation optimization, Acrot InSAR ground monitoring, and the AUTOPLAK microbiology lab automation device. In aerospace and defence, Sener is prime contractor for ESA's Proba-3 formation-flying mission (launched December 2024), contributes RF payloads and antennas to Airbus OneSat and SpainSat NG, supplies electro-mechanical controls for Raytheon's GEM-T missile in the Patriot FMS chain, and leads the HYDEF hypersonic interceptor consortium; the 2024 acquisition of SCR (Sistemas de Control Remoto) seeded the SRC 100 Razor stealth drone unveiled in February 2026.

Revenue is generated through project-tendered, multi-year fixed-price and cost-reimbursable contracts with governments, prime contractors (Airbus, Raytheon, Indra, MBDA), utilities (Uniper, Repsol, Petronor) and large infrastructure operators (ADIF, metro operators, port authorities). The group reported FY2025 revenue of €933 million, distributed across engineering services, EPC project delivery (LNG regasification, combined-cycle plants, metros, high-speed rail, solar thermal), and aerospace/defense hardware production in ISO 5-8 clean-room facilities. Sener reached position 38 in the ENR Top 225 International Design Firms ranking in 2025 (#1 Spanish international design firm) and operates wholly-owned subsidiaries Quark (data centers), SCR (autonomous systems), Tactix (Australia, 60%), and TRYO Aerospace & Electronics (100%), plus joint venture SATNUS Technologies for FCAS unmanned-vehicle technologies.
