Reflective

Data Scientist

• Lead work to determine what observations are needed to improve aerosol microphysical models and design decision-relevant outdoor experiments.
• Develop an inverse modeling framework to use SABRE, AToM, and other relevant in situ observational datasets to improve existing aerosol microphysical models, potentially including adjoint-based approaches.
• Design and run data denial experiments to determine which observations are most important for constraining microphysical parameters to help define a minimum viable instrument suite for a future outdoor field experiment.
• Develop formal Observing System Simulation Experiments (OSSEs) that simulate observations of an aerosol plume under different potential instrument suites, sampling strategies, and cadences to quantify the marginal value of different measurement strategies.
• Repeat OSSE analyses across a range of plume conditions, atmospheric states, and experimental configurations, and translate OSSE results into practical field campaign recommendations: where to sample, how often, at what altitude, with which instruments, and with what acceptable error bounds.
• Build data pipelines and processing workflows for future field experiment data, ensuring that data can be rapidly quality-controlled, analyzed, and used to update model parameterizations.
• Work closely with Reflective’s science, engineering, and data teams to translate model uncertainty into concrete observational requirements.
• Write scientific papers, concise memos, technical documentation, and public-facing summaries that make what has been learned, what remains uncertain, and how the results should inform experiment design  clear to funders, policymakers, researchers, and the wider field.

Senior Scientist, Data Assimilation – Observing Systems

Controller

• Own the financial backbone of the organization — running our financial controls, leading budgeting and forecasting, managing all cash in and out, overseeing spend and contracts, and producing the reporting leadership, the Board, and our funders rely on.
• Partner with the CEO and leadership team on the financial side of fundraising including building and maintaining the annual operating budget.
• Build dashboards and reporting cadences that allow for timely, accurate financial reporting for leadership, the Board, funders, and the broader team.
• Own cash-flow forecasting, runway modeling, and runway risk flagging — surface trade-offs early.
• Track actuals against budget by function and program, and surface variances early.Own cash-flow forecasting, runway modeling, and budget to actuals reporting and flag risks and trade-offs early.
• Translate the strategic plan and program roadmaps into financial plans, scenarios, and re-forecasts as priorities shift.
• Meet restricted-fund and funder reporting obligations credibly, not just procedurally.
• Manage all cash inflows and outflows — incoming grants and donations, vendor payments, and outgoing grant disbursements — and ensure commitments are tracked, paid correctly, and reflected in forecasts.
• Manage financial administration across the lifecycle of all external relationships from contracting to ongoing payments, invoices, and financial reporting across grant agreements (inbound and outbound), vendor and consultant agreements, statements of work etc.
• Hold function and program leads accountable to their budgets.
• Oversee banking relationships, payment controls, and treasury management.
• Build repeatable contracting processes and templates, and interface with external counsel on terms, compliance, and risk.
• Own accounting operations end-to-end — general ledger, month-end and year-end close, reconciliations, and the integrity of our books.
• Design, document, and enforce internal controls and approval workflows for expenses, corporate cards, reimbursements, and procurement that scale as we grow.
• Manage the external accounting relationship and lead the annual audit and 990 processes.
• Ensure compliance with GAAP, nonprofit accounting standards, and the requirements of restricted and unrestricted philanthropic funding.
