Early-career candidates, including recent graduates, are encouraged to apply * Hands-on evidence of building something real and making it work, such as a university cubesat or rocketry team, research lab, Formula Student, a hardware internship, or a project taken from nothing to working. We weight this far far above grades * Working proficiency in Python, * Space exposure in any form: CubeSat program, hosted payload, space or defense internship, or a space-focused Master's project * Optics and photonics bench work * Computer vision * Closed-loop pointing and control * End-to-end Environmental test and AIT experience * Systems engineering practice * Embedded or real-time software ## Description As a Payload Engineer I at Lodestar, you'll join the payload team as a primary delivery engineer, taking the payload from laboratory breadboard to qualified engineering model. You'll help design, build, integrate and test the payload across optics, mechanical, avionics and software. Working alongside senior systems, GNC, electronics and optics engineers, you'll take the engineering model through design reviews, integration and qualification. This is an early-career role with a deliberately broad scope. We're looking for hands-on building experience and fast learning rather than a long track record, and you'll own the engineering model from day one with the support to grow into it., * Own the payload engineering model day-to-day, end-to-end: requirements, design, build, integration, test, and write-up * Develop payload, autonomy, effector, power, thermal, and pointing requirements, and the ICDs between payload, avionics, and spacecraft bus * Prepare SRR, PDR and CDR packages, and keep the verification matrix and risk register current between reviews * Carry out performance verification and feed corrective design iterations back into the build * Run hardware-in-the-loop testing at internal & external testing facilities, closing the loop from perception through to pointing against simulated orbital targets * Support environmental qualification (TVAC, launch vibration, EMC/EMI), including pre-and post-test functional testing and the anomaly and corrective-action trail * Deliver an end-to-end ground demonstration on a payload-in-the-loop testbed * Produce technical documentation: test reports, qualification records, and performance assessments against requirements
