Senior Instrument Scientist

Cosmic Frontier's mission is to dramatically expand access to high performance space telescopes, democratize the scientific process, and build tools for exploring the Universe.Cosmic Frontier team members own the full lifecycle of spaceflight hardware and software, from early architecture through flight. We build and fly real hardware. The systems you build will go to orbit within the next two years.Role Description:We're looking for an instrument scientist to bridge science goals and instrument design, defining what our telescopes should measure and how we prove the data delivers.What you'll do:Translate science questions into requirements, observing modes, calibration strategy, and data quality metricsDrive trades across optics, detectors, readout, and operations with a bias toward flight worthy simplicityBe hands on from lab characterization through commissioning and on orbit calibrationWhat Success looks like in the first 90 days:Produce a v1 science to requirements map for the first instrument suite and observing modesWrite the calibration and commissioning plan, including what we measure on the ground versus in orbitDefine a v1 pipeline and validation approach tied to lab truth data and on orbit checksRequired qualifications:Education background in Astrophysics, Physics, Optical Engineering, or related field, plus meaningful experience building and operating scientific instrumentsProven ability to translate science goals into clear, testable instrument requirements, observing modes, and data quality metricsHands on experience with instrument characterization, calibration, and commissioning, comfortable working in the lab and close to hardwareStrong systems mindset with the ability to drive practical tradeoffs across optics, detectors, readout, and operations in a fast moving environmentDesired Qualifications:Experience working on spaceflight or small satellite missions, especially in lean or early stage teamsBuilt or defined data reduction pipelines and validation frameworks tied to ground truth and on orbit checksExperience making pragmatic design decisions under cost, schedule, and mass constraintsComfortable operating with ambiguity, taking ownership of first of kind systems, and shipping v1 solutions quicklyBenefits:Unlimited PTO, sick leave, parental leave, bereavement leave.Medical, dental, vision, reproductive healthcare, HSA/FSA, life and disability insurance, One Medical.401(k), education benefits, cell phone and Wi-Fi reimbursement, one-time work-from-home stipend, commuter benefits, wellness programs.Export control:Due to the nature of the products and information handled in this role, employment is restricted to U.S. Persons as defined by U.S. export control laws.Salary Band:L4: $120,000 – $160,000L5: $170,000 – $250,000Diversity and Inclusion:We encourage anyone who is excited about this role to apply, even if you don't meet 100% of the qualifications.
