Software Backend Engineer Jobs

At Lyft, our purpose is to serve and connect. We aim to achieve this by cultivating a work environment where all team members belong and have the opportunity to thrive. Marketplace teams are at the heart of our products and decision-making, owning everything from rider pricing to driver earnings, incentives, and efficient matching. We’re looking for passionate, driven backend engineers to build systems that empower our riders and drivers to have the best transportation experience possible through prediction, adaptivity, and personalization. The Pricing group is a centerpiece of Lyft’s Marketplace org, determining prices for all rideshare products and supporting new initiatives. Unlike the other Pricing teams, Price Orchestration does not focus on optimization, but rather the backend infrastructure to combine these optimization components with product requirements, orchestrating users’ pricing experiences. To accomplish this, we maintain and develop three platforms: pricing, discounting, and tax. We work in a cross-functional capacity, aligning product, science, legal, finance, customer support, and many other functions to solve and implement complex pricing requirements, balancing the needs of riders, drivers, and the business goals. As an owner of one of the most critical flows in the company, you will work on a wide array of challenges such as latency-sensitive concurrency problems, large scale distributed systems, and experimentation. If you’re interested in playing a large part in demand / supply management and improving the Lyft customer experience, this could be a great fit for you. Responsibilities: Drive high-impact projects and innovate new solutions to provide the best user experience. Work closely with cross-functional teams and partner teams to develop solutions based on technology and business needs, and advance team’s goals and priorities Independently lead features from idea to positive execution and launch Unblock, support and communicate with intern
