Less than 6 months from now, Flow delivers Crescendo, its biggest technical upgrade since launching the network. Included in the Crescendo release is Cadence 1.0, a major upgrade of the Cadence programming language which enables fully immutable smart contracts on Flow; as well as full EVM equivalence, allowing Flow to host EVM-based smart contracts, platforms, tooling, and utilities natively and fully composable with the Cadence environments. With Crescendo, Flow will be as easy to deploy onto as any EVM-based Layer 2, while preserving the full capabilities of the rest of the protocol. Crescendo upgrade will catalyze a massive improvement in liquidity on Flow including on- and off-ramps as well as a native DeFi ecosystem that serves as a liquidity backbone for the entire network.\n\n\nAt Flow Foundation, we prioritize recruiting top talent and cultivating an empowering environment for our team. This entails fostering a workplace that is characterized by diversity, inclusivity, and open-mindedness. We enthusiastically welcome applicants from all walks of life, regardless of race, color, religion, sexual orientation, gender identity, national origin, or disability. \n\n#Salary and compensation\n No salary data published by company so we estimated salary based on similar jobs related to Design, Web3, Node, Senior and Engineer jobs that are similar:\n\n $70,000 — $120,000/year\n
