About The Company
SIFT is a pioneering technology company dedicated to redefining how modern machines are built, tested, and operated. Our innovative platform provides engineers with real-time observability over high-frequency telemetry, eliminating bottlenecks and enabling faster, more reliable development cycles. Founded by a team with extensive backgrounds from SpaceX, Google, and Palantir, SIFT specializes in mission-critical systems where precision, scalability, and reliability are paramount. Our work is born from challenging aerospace projects, including SpaceX’s Dragon, Falcon, Starlink, and Starship programs, where scaling telemetry and debugging flight systems demanded groundbreaking infrastructure solutions. As a result, our solutions are tailored for high-stakes environments requiring meticulous data fidelity and performance.
About The Role
We are seeking a highly experienced Software Engineer to join our team and contribute to the development of our cutting-edge telemetry platform. In this role, you will be instrumental in designing and optimizing complex data pipelines that operate entirely within the browser environment. Your work will involve building interactive visualizations for time-series telemetry, frequency analysis, geographic mapping, and scatter plots, each demanding high performance and accuracy. You will tackle performance challenges that frameworks often cannot solve, such as bypassing React's render cycle for smooth 60fps interactions, managing large binary buffers, and coordinating worker thread pools. Additionally, you will architect composable UI systems that provide full data fidelity to technical users, supporting zeptosecond-level timestamp precision across the stack. Collaboration with backend engineers on API design, binary serialization formats, and structured data query semantics will be a key aspect of your responsibilities. This role offers an exciting opportunity to influence the architecture, shape product development, and help evolve a platform that supports complex, mission-critical systems from the ground up.
Qualifications
SIFT is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. All qualified applicants will receive consideration for employment without regard to race, color, religion, gender, gender identity or expression, sexual orientation, national origin, age, disability, or any other protected status under applicable law.
