Button's mission is to build a better internet, fueled by commerce. Today, we work with some of the largest and most interesting businesses in the world to connect consumers with what they want at the tap of a button. We build with the consumer experience in mind, have a reputation for paving the future of mobile, and have a good time doing it. As a Senior Software Engineer, you'll design and build the services, APIs, frameworks, UIs, and backend systems that sit at the very foundation of Button's business. Our portfolio includes the programmatic interfaces that connect Button to many of the largest brands in e-commerce, and real-time routing of customers to the ideal shopping experience. You will lead the design of new services and frameworks that advance our ambitious product goals. You'll be a key contributor to shaping our Engineering and technical culture, driving design reviews, and providing guidance and direction to developing members of our team. Our Engineering team values a fast-moving and high-trust environment that affords each member the opportunity to develop expertise operating services at a meaningful scale in a distributed cloud environment. You'll compose solutions from a broad range of technologies, including Go, NodeJS, Docker, Prometheus, and AWS ECS. You'll also move fast; we ship changes to production dozens of times each day.
