The applicant will develop and adapt the Scarlet source deblending software package for use with JWST Integral Field Unit (IFU) spectrographs (NIRSpec IFU and

MIRI MRS

), perform validation simulations, and produce open-source science demonstrations for the astronomical community.

Essential Duties/Responsibilities:

Port and modernize the prototype spectral Scarlet pipeline to the current Scarlet codebase for compatibility with

JWST IFU

data formats Integrate q3dfit for wavelength-dependent PSF modeling and deconvolution Design and run suites of synthetic data simulations (~10,000 blended scenes) to quantify deblending performance for NIRSpec and MIRI data cubes Apply Scarlet to archival JWST data across multiple science cases (quasar host galaxies, substellar companions, high-redshift galaxy clusters, SN1987A, etc) Write documentation, tutorials, and community-facing science demonstrations Contribute to open-source development and testing infrastructure on

GitHub Education:

PhD in Astronomy, Astrophysics, Physics, or a related field

Experience:

Candidates with at least 5 years of experience performing this type of work are highly preferred. Prior experience with IFU spectroscopy data reduction and analysis (NIRSpec, MIRI MRS, or comparable instruments) is strongly preferred. Experience with source deblending, spectral decomposition, or matrix factorization methods is a plus.

Knowledge, Skills & Abilities:

Strong understanding of observational astronomy, particularly IFU spectroscopy and photometry Familiarity with PSF modeling and convolution in the context of astronomical imaging Experience writing and maintaining scientific software in a collaborative environment Ability to design and interpret simulation-based validation studies Strong written and verbal communication skills for producing documentation and publications

Technology:

Proficiency in Python; experience with C/C++ extensions is a plus Familiarity with astronomical software ecosystems: JWST pipeline, q3dfit, jdaviz, WebbPSF, GALSIM, or similar Experience with version control (Git/GitHub) and open-source software development practices Familiarity with non-negative matrix factorization or related optimization methods is desirable

Working Conditions:

This job operates in a professional office environment. This role routinely uses standard office equipment such as computers, phones, photocopiers, etc. extensive online usage. This is largely a sedentary role.

Travel:

None. This position is contingent on contract funding. Applicants should apply to the posting at Home | USRA Careers and include a letter of interest, resume, or curriculum vitae. Additional information on USRA can be found at Home |
