Our Culture Our Leadership Team Our Contribution to the Technology Ecosystem Life at OBSS

OBSS is an engineering-led technology consultancy helping organisations build, modernise and scale mission-critical systems through AI-native delivery.

With over 20 years of engineering experience and more than 1,000 technology professionals, we work across banking and financial services, defence, insurance, aviation, retail and e-commerce, where business continuity, reliability and operational performance are essential.

Our expertise spans technology consulting, software engineering, cloud, data & AI, and experience design, underpinned by strong engineering discipline. We structure the delivery around AI within a governed engineering framework, with quality assurance and traceability built into every stage while retaining human review and approval. The result is more predictable delivery and systems our clients can rely on for years.

With offices in London, Istanbul and Ankara, we draw on the engineering expertise developed in Türkiye to serve clients internationally.

Reliable engineering starts with strong teams. Our people bring technical depth, diverse expertise and a commitment to continuous improvement. Collaboration, learning and development are part of everyday work, deepening our teams’ expertise as they build and evolve the systems our clients depend on.
