Nice to have - Experience with decentralized finance, NFT marketplaces, layer-two infrastructure, developer SDKs, or gaming products.

Benefits and work setup - Full-time and remote worldwide, with a flexible 10:00–19:00 schedule and employment arrangements based on location. - Medical, dental, and vision coverage, paid time off, personalized career planning, and professional development support.
