Yet today designing an electronic circuit board is an extremely manual, long and tedious process. At Circuit Mind we believe that this is wrong and we are on a mission to fix it, triggering the future of hardware design.\nWe are creating an entirely new software engine for circuit boards, that takes as inputs the requirements of a circuit board and automatically outputs a complete design, ready for manufacture.\nAs a Lead Software Engineer, you’ll create simple and elegant solutions to difficult technical problems that the world has not solved before. You will work in close collaboration with a highly-functioning team of software, electronics, algorithm engineers and product managers.\nTasks\nCollaborate with the product team and in-house hardware engineers to understand the problems of hardware engineering teams.\nPlan, design, develop, test and iterate on the software solutions to those problems, accounting for functional and non-functional requirements.\nCo-design, pair on, and review the development work of other lead software developers.\nYou’ll work on the entire company's backend code base: data models, algorithms, data pipelines, infrastructure, APIs, complex database queries, ML models.\nLearn, use, and improve best practices and processes for high-quality software development.\nOur technology stack includes Python 3.11, PostgreSQL, Django, mypy, GraphQL, Docker, Redis, Typescript, React.\nRequirements\nWe’re only considering exceptional candidates, with the following pre-requisites:\n5+ years of professional software development experience.\n2+ years of professional experience in Python.\n2+ years in a senior software engineer position.\nStrong communication and team-work skills.\nExperience working in an agile software development environment.\nNice-to-haves\nExperience in a tech lead position.\nAn interest in electronic engineering.\nBenefits\nCollaboration with a friendly world-class team.\nAbove market
