Role Description We are hiring an Index Data Scientist to own the methodology layer of every RTI ranking — the formulas, weights, confidence scoring, and ranking logic that turn raw regulatory data into a defensible, sponsor-ready index. You will translate prototyped scoring into transparent, auditable models, and you will build the playbook for launching net-new indices on demand (rare earths, data center, healthcare services, energy). You will be the person who can sit in front of a sponsor, a regulator, or a board member and defend why the index says what it says. You will work directly with the Data Science and the Web Scraping team. Key Responsibilities - Own the methodology layer for every published RTI index — weighting, normalization, confidence scoring, and ranking logic. - Translate prototyped scoring into transparent, defensible models with documentation a client, regulator, or auditor can read end-to-end. - Build the new-index playbook: required data, methodology template, confidence calculation, coverage thresholds. - Validate cross-source decisions with statistical rigor: correlation, drift, sensitivity, robustness to missing data. - Partner with sponsoring companies to translate commercial questions into index methodology — without compromising independence. - Publish methodology one-pagers and FAQ pages alongside each index, suitable for press, sponsors, and regulators. - Work with the Web Scraping Engineers on schema and data-quality requirements. - Lead methodology reviews and owns the change-log when an index is updated. Qualifications - 3+ years building indices, benchmarks, scoring models, or rating methodologies in production — at a rating agency, index provider (MSCI, S&P, FTSE, Bloomberg), actuarial consultancy, or equivalent. - 3+ years quantitative background — actuarial science, statistics, econometrics, applied math, or equivalent. - Proven ability to write methodology documentation that holds up to external scrutiny (regulator, client, auditor). - Strong stakeholder communication — can defend a model to a non-technical CEO and a skeptical analyst in the same meeting. - Python and SQL fluency; comfortable in pandas / NumPy and at least one ML / stats library (scikit-learn, statsmodels, R). - Experience with cloud data platforms (GCP, AWS, Supabase). - Strong problem-solving skills; comfortable with ambiguous, partial, and messy data. - Strong English communication; comfortable presenting to executives and external partners. Nice-to-Have - Has built a published index from zero — designed it, defended it, iterated it. - Background in regulatory, real estate, healthcare, energy, or commodities markets. - Experience with public-sector data, government statistics, or planning / permit datasets. - Experience with sponsor- or client-facing index work where independence and defensibility matter. - Familiarity with LLMs for prototyping methodology or generating documentation. Benefits - Remote-first; primary collaboration in Americas time zones with ~5 hours overlap. - Fully remote, flexible hours. - Payment in USD (contractor / freelance basis); full-time conversion possible for the right person. - Work on a global team, with real-world challenges and rapid growth opportunities.

• Own the analytical strategy for the end-to-end marketing funnel, from marketable lives to lead generation to omni-channel engagement strategy to visit completion and re-engagement. This includes our call center function (outbound rep allocation, inbound referral scheduling, ZCC data) and member lifecycle (Customer.io journey performance, reactivation, and initial visit completion optimization). • Own the product analytics domain: onboarding funnel, sign-up conversion, in-app engagement, and the member experience through completed first appointment. Partner with the top-of-funnel product team as their embedded analytical lead, attending product cadences and co-owning the product analytics roadmap. • Serve as the executive-facing owner of the marketing and product performance narrative: explaining why marketable lives, funnel conversion, and initial visit completion moved, what levers drove the result, and what to double down on. • Design and lead Foodsmart's experimentation program across both marketing and product, including test design, causal inference methods, readout discipline, and the intake process for stakeholder-driven test ideas. Own the StatSig implementation and serve as the internal expert on experiment instrumentation, StatSig configuration, and results interpretation. • Own and evolve our attribution framework, including scheduling episode attribution, multi-touch attribution, and media mix modeling as Foodsmart's channel portfolio grows. • Partner with Growth Marketing leadership as the embedded analytical lead: attending marketing cadences, co-owning the analytics roadmap, and driving insight into action. • Own and evolve the dbt data models for the marketing and product domains — from raw source modeling through mart-layer metrics — ensuring data quality, test coverage, documentation, and a semantic layer that makes self-service trustworthy. This is a core craft expectation of this role, not a secondary responsibility. • Engineer context into our semantic layer and BI environment (Omni) so that stakeholders and AI agents can reliably self-serve answers across the marketing and product funnel. You treat context engineering — writing descriptions, defining metrics, curating what's exposed — as a first-class part of your job. • Drive the narrative, not just the numbers — translate findings into clear, actionable recommendations for executive and marketing leadership audiences. • Raise the bar for the analytics team on the craft areas central to this role — experimentation design, dbt modeling patterns, and context engineering. You don't manage anyone, but you operate as a technical leader: establishing best practices, reviewing work, and making the team around you better.
