\nHelloSign is a leading provider of eSignatures, allowing you to sign documents when, where, and how you want. Our mission is to make our users awesome -- and build an equally amazing team founded on transparency, collaboration, and fun.\n\nThe Role\n\nHave you architected a platform to achieve 10x capacity? Do you have experience managing the complexity of long-running concurrent jobs? Are you brimming with opinions about how best to eliminate side effects and simplify concurrency management? If so, let's chat!\n\nIn addition to being highly skilled on the technical side, you consistently put yourself in the user's shoes and think critically about what you're building. Some other challenges you'll help us with:\n\n\n* Developing a fast, reliable platform for our eSignature API and end-user website.\n\n* Researching new processing and data storage technologies.\n\n* Scaling our system to support millions of users.\n\n* Improving our test frameworks and operational tools.\n\n\n\n\nOur back-end tech stack is Symfony PHP, MySQL, ElasticSearch, Redis, memcached, and beanstalkd, all deployed to AWS using chatops by a friendly robot named HAL 9000 -- however we believe in using the right tool for each job. \n\nOur Engineering Team\n\nOur team of 8 engineers is friendly, curious, driven, and highly collaborative. We support one another and regularly hold code reviews to facilitate learning and reduce friction during our 3-week releases. We strive for clean, readable, maintainable code. Our engineers also work closely with other teams in the company, including creative, product, and customer support. The entire company works together at our open office in downtown San Francisco.
