Nethermind Tech Stack

Ethereum protocol engineering, L2 scaling, and blockchain security services

IT Services and IT Consulting London, London 201–500 employees Founded 2017 Privately Held

Nethermind is a protocol-focused engineering shop building on Ethereum, StarkNet, and Cairo, with active R&D across layer 2 scaling and DeFi. The hiring mix reveals a shift toward security and product alongside core engineering—security roles match pain points around cryptographic verification of AI agents and early-stage security gaps, while concurrent go-to-market and SDK tooling projects signal movement from pure R&D toward productized offerings. Recent adoption of Stripe hints at monetization infrastructure buildout.
