Consistently sets high standards for code quality, testing practices, and code review processes.\n\n\n\nBenefits\n\n* Work on some of the most exciting problems between the cross-section of finance and engineering.\n\n* Work with exceptional leaders from companies like Meta, Robinhood, and LinkedIn. Each team member has helped grow products to billions of users and revenue!\n\n* A competitive compensation package that includes tokens, equity, and cash.\n\n* Good vibes.\n\n\n\nOur Culture\n\n* \nWe value feedback — if you’re not growing, you’re growing weaker! We think feedback is a gift and a crucial tool to push us to be better. You’re expected to not only receive feedback but also give feedback to anyone at the company.\n\n* \nWe move fast — speed is in our DNA, from engineering to iteration to hiring. We’re constantly pushing the boundaries of how fast we can learn, grow and succeed.\n\n* \nWe expect excellence — from code to design to product analysis. We set a high bar for ourselves and the products we build.\n\n\n \n\n#Salary and compensation\n No salary data published by company so we estimated salary based on similar jobs related to Design, Finance, Senior and Engineer jobs that are similar:\n\n $57,500 — $92,500/year\n
