Advancement To:

  • Senior Astronomer / Research Scientist
  • Instrument Scientist or Observatory Operations Lead
  • Principal Investigator (PI) / Group Leader
  • Faculty (Assistant/Associate/Full Professor) or Astronomical Research Director

Lateral Moves:

  • Data Scientist / Machine Learning Engineer (astro‑data specialization)
  • Scientific Software Engineer or DevOps (HPC/cloud for science)
  • Science Communications / Public Outreach Specialist

Core Responsibilities

Primary Functions

  • Design and execute observational programs using ground‑ and space‑based facilities (e.g., JWST, HST, ALMA, VLA, Keck, Subaru), including target selection, exposure time calculations, and observing strategy to maximize scientific return.
  • Reduce, calibrate, and analyze raw astronomical data across modalities (optical/IR imaging, spectroscopy, integral‑field, radio interferometry), producing publication‑quality data products and reproducible reduction workflows.
  • Develop, test, and maintain automated data reduction pipelines and analysis software (Python, Astropy, NumPy, SciPy, CASA, IRAF legacy conversions) to ensure scalable processing for surveys and time‑domain campaigns.
  • Lead instrument commissioning and performance characterization: generate calibration plans, measure throughput and sensitivity, evaluate optical/IR/radio instrument stability, and implement mitigation strategies for systematics.
  • Produce scientific results and lead authorship of peer‑reviewed journal articles, technical memos, and observatory reports; prepare figures, tables, and methods that meet community standards.
  • Write, submit, and manage telescope proposals (standard, large programs, target‑of‑opportunity) and competitive grant applications (NSF, NASA, ERC or national agencies), including budgets, justifications, and deliverables.
  • Plan and execute observing runs onsite or remotely, coordinating with observatory staff, instrument scientists, and support engineers to ensure safe, efficient operations and rapid response to technical issues.
  • Implement statistical inference and modeling methods (MCMC, Bayesian analysis, maximum likelihood, hierarchical models) to interpret observations and quantify uncertainties for cosmology, exoplanet, or stellar population studies.
  • Design and run numerical simulations and forward‑modeling codes (N‑body, hydrodynamic, radiative transfer) to compare theoretical predictions with observational data and inform observing strategies.
  • Manage and curate large astronomical datasets: ensure data provenance, versioning, metadata standards (FITS headers, VO compliance), and submission to public archives or collaboration repositories.
  • Coordinate multi‑wavelength and multi‑facility campaigns, integrating heterogeneous datasets, scheduling contemporaneous observations, and harmonizing calibration across instruments.
  • Optimize and parallelize computational codes for HPC and cloud environments (MPI, OpenMP, GPU acceleration, Slurm, AWS/GCP) to handle survey‑scale processing and machine‑learning inference at scale.
  • Mentor and supervise undergraduate students, graduate students, and postdoctoral researchers; delegate tasks, review analysis, and foster professional development in scientific methods and research ethics.
  • Represent the project or observatory at scientific conferences, time allocation committee (TAC) meetings, and stakeholder briefings to communicate results, secure resources, and build collaborations.
  • Troubleshoot complex instrument and software issues: diagnose detector artifacts, scattered light, spectral cross‑talk, or pipeline failures; design calibration routines and software patches to restore data quality.
  • Implement and maintain software engineering best practices for research code: unit testing, continuous integration, code review, documentation, containerization (Docker/Singularity), and version control (git).
  • Lead time‑domain and transient response operations, including rapid target‑of‑opportunity triggers, automated alert ingestion (VOEvent, ZTF, LSST alerts), and fast‑turnaround data reduction for follow‑up observations.
  • Engage in outreach and public communication: prepare press releases, public talks, and visualization products; translate complex astronomical findings into accessible content for diverse audiences.
  • Coordinate procurement, budgeting, and vendor interactions for instrument upgrades or custom hardware; prepare technical specifications and evaluate vendor proposals.
  • Ensure compliance with observatory safety protocols, data management policies, funding agency requirements, and institutional review processes; maintain accessible, reproducible workflows and data releases.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
  • Maintain and improve public data releases, user documentation, and tutorials for community uptake of survey products.
  • Assist in the assessment and selection of new instrumentation concepts, prototypes, and technology readiness reviews.
  • Serve on internal committees (observing time allocation, data rights, software governance) and contribute to development of data policies.
  • Provide expert consultation on observing feasibility, instrument modes, and tradeoffs for multi‑disciplinary science teams.
  • Support diversity, equity, and inclusion efforts within research groups and help recruit underrepresented talent into astronomy programs.
  • Participate in outreach programs to local schools, planetariums, and media contacts to raise the profile of the research program.
