As a Manufacturing Engineer in the Solar Power group, you will be part of a team responsible for the build and integration of solar array systems that power spacecraft for customers in all sectors of the space economy. Sierra Space has developed and patented novel pick-and-place surface mount solar cell technology which will revolutionize the way space rated solar power systems are built. You will be a part of the team that will scale the process to enable world-class high-volume production and test of both small and large solar power systems, including multi-panel deployable arrays. This role will work heavily alongside the design, test, program management and quality teams to ensure that all schedule and quality objectives are consistently met for our customers, and that we are advancing the state of the art for Solar Array build efficiency. Key responsibilities include reviewing engineering designs for producibility, developing tooling, fixtures, and facilities, and establishing overall build plans to support efficient manufacturing processes. This role involves executing new product introduction (NPI) builds across all work centers, performing process development, validation, and transitioning to production within aggressive timelines. You will assist with the initial concepting, setup, and programming of Printed Circuit Board Assembly (PCBA) lines, including facility requests and equipment setup, while also programming, operating, and training technicians on automated equipment during the initial standup phase. Collaboration with the tooling team will be essential to design custom fixtures for PCBA, ensuring efficient process flow and seamless integration with Surface Mount Technology (SMT) lines. Additional responsibilities include triaging non-conforming products, driving resolution and preventative actions, resolving production issues while maintaining design integrity, product quality, and delivery timelines, and identifying opportunities for continuous improvement in yield, rate, and cost. You will also define and execute maintenance schedules, support activities, and specify equipment requirements for new build processes. This role includes performing internal research and development (IRAD) designs to optimize SMT process yield, developing design for manufacturability (DFM) guidelines, and providing solutions to streamline space-grade circuit board assembly and test processes, including flying probe, AOI, functional testing, reflow soldering, selective soldering, and conformal coating. Finally, you will facilitate close collaboration with the engineering team throughout design, build, and test phases to provide critical design feedback and ensure alignment with production goals.
