Jonas Lerebours joins Dfns as our first Senior Solutions Engineer, helping onboard clients and supporting developers as we scale.

We’re excited to welcome Jonas to the team. He brings over 10 years of experience helping developers and enterprise clients adopt complex technologies in fields like robotics, communications, and cybersecurity. Jonas has spent the past decade working at the crossroads of integration, support, and infrastructure. He’s deployed humanoid robots at SoftBank Robotics, scaled communication APIs at Twilio, and most recently helped secure software adoption at ProvenRun. Now at Dfns, he’ll strengthen our client enablement efforts and help institutions build onchain with confidence.

A career in dev tools, robotics, and cybersecurity

Jonas has spent over a decade working across software integration, real-time systems, and customer enablement. He began his career at SoftBank Robotics, where he spent six years helping deploy humanoid robots like NAO and Pepper in both business and public sector settings. As a Field Application Engineer, then Sales Engineer in San Francisco, and later FAE Manager for EMEA, he delivered technical support, built custom demos, maintained documentation, trained developers, and helped shape product roadmaps based on customer needs across multiple regions.

He went on to join Twilio as a Senior Solutions Engineer, working with enterprise clients to scale communication APIs. His role involved guiding teams through complex integrations, advising on architecture, and supporting onboarding in fast-paced, highly regulated environments. Most recently, at ProvenRun, he supported clients in critical sectors as they integrated high-assurance security software into embedded systems, bridging the gap between advanced cryptography and real-world deployment.

In every role, Jonas has worked at the interface between product and customer, turning complex stacks into practical, reliable solutions. That mindset is core to his work and to what he brings to Dfns.

Scaling support for blockchain operations in finance

Jonas joins Dfns to strengthen a key function: helping clients go from integration to production, faster and with greater confidence. He’ll work closely with our engineering, account management and sales teams to guide new teams through onboarding, support API and platform configurations, and ensure smooth deployments across a range of use cases, from launching stablecoins and managing treasuries to building highly secure custody setups, automated payment rails, complex trading schemes, and more.

This work is more important than ever. Blockchain is entering a new phase: institutions aren’t just experimenting anymore but are building production ready systems, with engaged clients, and real value at stake. Security, governance, and compliance remain essential, and so does usability and speed to market. Dfns already supports some of the most demanding teams in crypto finance. As adoption grows, Jonas will play a key role in making sure our infrastructure is fully operable in the hands of those who rely on it.
