Social Media Manager

Mission of the Role:
You are the first content hire and the first public face of the brand: you own the engine end-to-end, from strategy to the post itself, across Instagram, LinkedIn, and X, with an AI stack that lets one operator do the work of a small content team. Turn longevity science (dense, fragmented, intimidating) into content American consumers actually understand, save, and share.
Core Responsibilities:
Own the content strategy from zero: positioning, tone of voice, content pillars, and a rolling monthly calendar for a US audience. There is no brand book and no brief waiting for you. You write both.
Run the channels end-to-end: Instagram (Reels, carousels, Stories), LinkedIn (including posts under the founder's name), and X. Each channel gets native formats, not one post copy-pasted three ways.
Produce the creative yourself: visuals in Canva/Figma, short-form video shot on a phone and cut in CapCut. There is no designer and no producer. Taste is part of the job spec.
Build the community: comments, DMs, early-user relationships. The first cohort of people who care about Chia is yours to find and keep.
Own social metrics end-to-end: reach, engagement, saves, follower growth by channel. Weekly hypothesis → test → learning loop, documented so it compounds.
Run an AI-native content workflow: Claude/ChatGPT for research and drafts, Midjourney/Ideogram for visuals. Target: content throughput that would otherwise require three people.
Requirements:
Must have:
2–4 years in social media / content / community at a US-facing product company: in-house, not agency or outsourcing. You owned a brand, you didn't execute someone else's brief.
Native or near-native English: you write for a US audience with cultural fluency and a real voice. This is a writing role in English; there is no localization step and no editor behind you.
A portfolio of live accounts you personally ran, from strategy through publishing. With numbers, and with an honest account of what didn't work.
Full-cycle execution: idea → copy → visual → publish → analyze, done by you, without handoffs.
Instagram as your core surface: Reels, carousels, Stories, and the direct-message layer underneath them.
Hands-on creative production: Canva (required), Figma (plus), phone-shot video and CapCut editing.
Comfort with ambiguity: pre-seed means there's no playbook. You're inventing the process while running it.
Strong AI workflow practice: daily Claude/ChatGPT use, hands-on with content automation.
Personal interest in the topics: health, wellness, longevity.
Nice to have:
Professional background in longevity, wellness, healthspan, or biohacking.
Track record launching an account from zero to a meaningful US audience.
Experience building a founder's personal brand.
Familiarity with FDA-friendly marketing claims (or willingness to learn fast).
Pre-seed/seed startup experience where you had to invent the playbook, not follow one.
Explicitly not a fit:
Strategists who direct a team of designers and copywriters: there is no team.
Performance/paid acquisition specialists: that is a different role at Chia.
Portfolios of polished decks with no live accounts behind them.
Anyone whose English works for messaging but not for writing brand voice.
Expected Results (Probation KPIs, 90 days):
Day 30: Content strategy and tone of voice documented and approved. All three channels live and posting on a consistent cadence (target: ≥X posts/week per channel, we'll align on numbers). Baseline metrics established.
Day 60: A repeatable weekly content engine running (concept → creative → publish → review) with the founder-voice LinkedIn track fully owned by the SMM. Measurable engagement and follower growth vs. the Day-30 baseline, with documented learnings.
Day 90: Content calendar owned independently one month ahead. At least one format proven to outperform baseline and scaled. Community layer active: DMs and comments handled within 24h, first cohort of ≥Y engaged US followers identifiable.
Qualitative: CEO trusts the SMM to publish under his name without line-editing. Content ideas originate with the SMM, not with the founder.
What to Expect in the Interview Process:
Culture Fit / Soft Skills Interview (up to 60 min), with Recruiting Manager. Values alignment, communication style, and vibe check. We're listening for directness and clarity of thinking.
Work Product Review / Portfolio Deep-Dive. Candidate walks through 2–3 live accounts they personally ran: what the strategy was, why those formats, what the numbers did, what they'd do differently. No prep needed: real accounts, not a polished version. We're looking for taste, systems thinking, and honesty about what flopped. We follow up within 3 business days.
Technical Interview with CEO (60 min). Deep dive into hard skills: what you built, decisions made, what you'd do differently. We also cover Chia's mission and your motivation for working in longevity at pre-seed.
Test Assignment (up to 1 hour, if needed). One short, realistic task (for example, a founder-voice LinkedIn post or a Reels script for Chia) if the portfolio left open questions. If it didn't, we skip this step.
Reference Collection. 2–3 references from former managers or collaborators. We actively probe for challenges and failures, not just highlights.
2-week paid trial. Real tasks with the team, mutual evaluation: the first two-week content plan, live posts, and the AI workflow in action happen here, paid, not as an unpaid take-home.
We send candidates a short prep doc with links to our product, market, and content references, so everyone walks into the process with the same baseline.
