Run the growth loop — programmatic SEO, lifecycle email, and conversion experiments — end to end.

**About Arithmos.** Arithmos is building the retail layer for direct indexing. We turn a plain-English idea into a transparent, rule-based portfolio with institutional-grade backtesting and analytics.

**The role.** You will own the top-of-funnel — programmatic SEO surface (locations, comparisons, blog), lifecycle email + push, signup + paywall conversion, and the experiment infrastructure that lets us learn weekly. Half engineer, half growth lead.

### What you’ll do

**Programmatic SEO + GEO**

- Expand /locations and /compare to thousands of well-targeted pages
- Own the schema.org + llms.txt surface for generative engines
- Run on-page + technical SEO experiments to chart-topping result

**Lifecycle + activation**

- Email/push/in-app drip — verify-email, first-build, rebalance day
- Onboarding A/B tests on the help-me modal + roll-the-dice flow
- Win-back loops for lapsed Plus subscribers

**Conversion + paywall**

- Pricing-page experiments and Stripe checkout copy
- Tier-gating UX (locked-range banner, upgrade prompts)

### Requirements

- 4+ years owning growth at a SaaS or consumer fintech product
- Strong technical chops — comfortable shipping React/Next.js code yourself
- Built programmatic-SEO sites that ranked
- Numbers-led: comfortable in PostHog / Mixpanel / SQL

### Nice to have

- Background in fintech / investing / brokerage
- Worked with Resend, Postiz, or other lifecycle toolingImagine you want to
