How OnHires helped SOCKET hire protocol engineering talent for cross-chain infrastructure growth

Cross-chain infrastructure companies need highly specialised engineers who can design secure protocols, reason about complex distributed systems, and build technology that operates reliably across multiple blockchain networks.

As SOCKET continued developing its modular protocol and expanding its infrastructure capabilities, it needed to strengthen its technical team with a Protocol Engineer. The company required an engineer who could contribute to protocol design, implementation, and performance while navigating the technical complexity of cross-chain applications and decentralised finance.

Because the role directly affected the security, scalability, and reliability of SOCKET’s infrastructure, the company needed a focused recruitment process that could identify the right technical profile quickly without lowering its engineering standards.

Hiring protocol engineers is particularly difficult because the relevant talent pool is significantly smaller than the broader software engineering market. Suitable candidates need strong computer science fundamentals alongside practical experience with blockchain architecture, smart contract systems, distributed protocols, or decentralised infrastructure.

SOCKET needed to hire a Protocol Engineer capable of working on technology that connects applications, users, and assets across multiple chains. The role required deep technical expertise, strong systems thinking, and the ability to make sound engineering decisions in an emerging and rapidly changing environment.

Competition for experienced blockchain engineers was also intense. SOCKET needed a recruitment process that could distinguish genuine protocol expertise from general Web3 exposure and keep qualified candidates engaged through a technically demanding evaluation process.

OnHires implemented a specialised recruitment strategy aligned with SOCKET’s protocol architecture, technical standards, and cross-chain product roadmap.

We began with detailed role calibration to define the required engineering depth, relevant blockchain experience, and expectations for the Protocol Engineer position. The scorecard focused on distributed systems knowledge, protocol design, security awareness, technical ownership, and the ability to solve complex infrastructure problems collaboratively.

We then mapped the global blockchain talent market and built targeted sourcing pipelines across protocol engineering, smart contract infrastructure, decentralised finance, distributed systems, and Web3 development communities. Structured screening and calibrated interviews helped the team identify candidates with genuine protocol-level expertise rather than surface-level blockchain experience.

OnHires managed the process end to end, including sourcing, screening, weekly hiring operations, feedback coordination, offer management, and onboarding support.

The structured recruitment programme helped SOCKET secure specialised protocol engineering talent while maintaining a rigorous technical quality bar.

By defining clear evaluation signals at the beginning of the search, OnHires improved the relevance of candidates entering the interview process and reduced time spent reviewing profiles without sufficient protocol experience. Weekly hiring operations also accelerated feedback and kept the search moving in a competitive global market.

SOCKET successfully hired a Protocol Engineer capable of contributing to its cross-chain infrastructure and Modular Order Flow Auction protocol, creating stronger engineering capacity for future product development.

This case demonstrates how specialised recruitment can help blockchain companies access scarce protocol engineering talent without compromising technical quality.

By combining global market mapping, role-specific sourcing, and structured technical evaluation, SOCKET hired an engineer aligned with the complexity of its cross-chain infrastructure and strengthened the team responsible for developing its core protocol.
