Core Responsibilities

Primary Functions

Lead end-to-end structure determination projects by designing and executing crystallization experiments, optimizing crystal growth conditions (co-crystallization and ligand soaking), and preparing samples for in-house and synchrotron data collection.
Plan and coordinate synchrotron beamline visits and remote data collection, including beamtime booking, sample logistics and cryo-protection strategies, to maximize experimental throughput and data quality.
Collect and process X-ray diffraction data using established and custom pipelines (e.g., XDS, DIALS), evaluate data quality metrics, and determine optimal processing strategies to rescue low-quality or anisotropic datasets.
Solve phases for novel and derivative crystals using experimental phasing (SAD/MAD), molecular replacement (Phaser, MOLREP), and hybrid approaches, tailoring strategies for difficult phasing problems and low-resolution data.
Perform model building and iterative refinement using Coot, PHENIX.refine, REFMAC, or SHELX, incorporating ligand restraints, alternate conformations, and proper treatment of metal centers and cofactors.
Validate final models rigorously with MolProbity, PDB-REDO, and internal QA procedures, produce validation reports and implement corrective modeling steps to meet journal and PDB deposition standards.
Deliver structure-based interpretation and actionable recommendations for medicinal chemistry, enzyme engineering, or material optimization, including detailed binding-site analysis, hydrogen-bond networks, and solvent mapping.
Lead fragment-based screening campaigns and crystallographic fragment screening workflows, analyze binding modes, and prioritize fragment hits for follow-up biophysical and biochemical validation.
Integrate crystallographic data with complementary biophysical datasets (SPR, ITC, HDX, SAXS) and computational modeling (docking, MD) to build cohesive mechanistic hypotheses.
Maintain and develop standardized computational workflows and automation scripts for high-throughput crystallography pipelines, enabling reproducible, scalable delivery to clients.
Provide expert troubleshooting for challenging crystal systems (twinning, merohedral twinning, severe anisotropy, lattice disorder), and implement advanced refinement strategies (TLS, NCS restraints, anisotropic B-factors where appropriate).
Manage client projects end-to-end, including scoping, timeline estimation, milestone tracking, deliverable preparation (figures, methods, PDB files), and post-delivery scientific support.
Prepare high-quality reports, manuscripts, posters and presentations summarizing crystallographic results, methods, and interpretations tailored to both technical and non-technical stakeholders.
Supervise and mentor junior scientists and technicians in crystallization techniques, data processing, refinement best practices and beamline operation protocols to build client capability and internal expertise.
Configure and maintain laboratory crystallization resources (robotics, imaging systems, cryo-tools) and advise on procurement, calibration and SOPs to ensure consistent experimental performance.
Ensure compliance with safety, data management and IP policies, anonymize client data when required, and manage secure transfer and archiving of diffraction images, structure files, and metadata.
Act as a technical liaison with synchrotron facility scientists, coordinate remote-data collection runs, and represent the organization in beamline user committees or facility collaborations.
Design and deliver training workshops and webinars on crystallography best practices, data-processing workflows, and advanced refinement techniques for client teams and academic collaborators.
Drive continuous improvement of service offerings by evaluating new software (AI-assisted model building, cryo-EM hybrid modeling), methodologies and instrumentation to expand capabilities and reduce turnaround time.
Provide consulting on experimental design for complex constructs (fusion proteins, truncations, selenomethionine labeling, heavy-atom derivatives), expression/purification strategies and stability engineering tailored for crystallographic success.
Oversee PDB deposition and metadata curation, ensure compliance with community standards, prepare structure factors and coordinate DOI/identifier generation for publications and client records.
Evaluate and support intellectual property efforts by preparing structural evidence packages for patent filings and collaborating with legal teams to preserve patentable insights.

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.
Assist sales and business development with technical input for proposals, statements of work, and client scoping sessions.
Maintain up-to-date documentation of laboratory protocols, beamline SOPs, and computational pipelines to support quality assurance and knowledge transfer.
Provide emergency troubleshooting support during critical client experiments or on-call beamline activities.
Monitor the literature and emerging tools in structural biology to recommend new service lines (e.g., time-resolved crystallography, room-temperature serial crystallography).
Help design and implement metrics for service performance (turnaround time, success rate, client satisfaction) and participate in regular review cycles.
