The calculation engine at the core of XiP is both highly performant and rapidly changing to support new scenarios, technologies, and infrastructure.
As an engineer working on XiP, you will work on a platform which daily; coordinates hundreds of thousands of pods, consumes tens of thousands of compute cores, utilizes hundreds of TB of memory, and distributes hundreds of millions of calculations.
You will work closely with software engineers, DevOps, and our customers to ensure reliable, secure, and scalable operations of the platform.
Responsibilities:
- Take part of the shared responsibility for the long-term strategic direction of the XiP Platform: Apply your experience and skills to develop the future versions of the calculation engine. This means making it faster, utilize resources better, and scale to even greater sizes. This means adding new features without impacting performance of the platform in undesirable manner, small changes multiplied by millions of calculations have a high cost. This means solving hard problems like transferring small amounts of data to a huge number of machines.

Design and deliver an API to empower our users to be able to have a controlled level of access to the pipeline which allows them to customize how the application is run for their use cases.
- Design and build new mechanisms for rapid testing of the platform: Improve the current system test mechanism to enable rapid and reliable testing of the platform, and work closely with DevOps engineers to evolve / create the next generation test mechanism suitable for daily release cycle of microservice components.
- Plan, coordinate, and execute strategic changes to the calculation platform to reach the next scaling milestone: Develop and manage strategic initiatives aimed at scaling the Xing Calculation Service to meet future business demands. Coordinate with stakeholders to ensure that all scaling efforts are aligned with customer needs.
- Provide specialized customer support to optimize and improve large, distributed calculations: Act as a primary point of contact for clients to address issues and optimize inefficiencies that arise during distributed workload execution.
