A Senior Backend Software Engineer at Palantir builds software at scale to transform how organisations use data. You will collaborate closely with technical and non-technical teammates to understand our customers' problems and build products that solve them. We encourage movement across teams to share context, skills, and experience, so you'll learn about many different technologies and aspects of each product. Engineers work autonomously and make decisions independently, within a community that will support and challenge you as you grow and develop, becoming a strong technical contributor and engineering leader.

Your day-to-day workflow will vary, adapting to the requirements of our users and the technical challenges that arise. One day, you may find yourself collaborating with other engineers to architect a new system that enables a novel workflow, the next you could be fine-tuning performance to enable low-latency operational outcomes.

We’re hiring engineers who are passionate about solving real-world problems and empowering both developers and end-users to work optimally. If you’re motivated to develop reliable, performant, and scalable systems, and to design robust APIs and primitives, this role offers the opportunity to make a significant impact on our products and the people who use them.

As a Senior Backend Software Engineer, you will lead the architecture, development, and maintenance of high-performance, scalable backend services that underpin our operational data and AI systems. You will maintain high coding standards through the development of guidelines, active participation in code reviews, and fostering a culture of continuous improvement and knowledge sharing among your team.

You will build robust APIs for use by front-end developers and interface external systems, and collaborate with front-end developers to integrate user-facing elements with server-side logic. You will design efficient data structures and algorithms to manage large-scale and high-throughput data, and optimize applications for speed and scalability through performance analysis.
