The Opportunity

We’re looking for a performance-driven, clinically fluent B2B HCP & Marketing Lead to help us scale our partnerships and HCP channels. This is a high-impact, cross-functional role for someone who thrives at the intersection of scientific storytelling, practitioner acquisition, partner marketing / sales enablement, lifecycle marketing and strategic B2B growth.

You’ll own the marketing strategy for our HCP (healthcare practitioner) and enterprise channels, educating practitioners, functional medicine networks, wellness brands and longevity clinics on our microbiome testing platform, and leveraging both paid and organic channels to drive qualified leads to our B2B funnel, ensuring optimal conversions.

What You’ll Do

B2B & HCP Go-to-Market

• Design and execute lifecycle marketing campaigns for healthcare providers (HCPs), clinics, and enterprise prospects, across email, webinars, social, website, blog and paid media

• Own the go-to-market strategy for new B2B products or enterprise offerings (e.g., new metric/marker or product launches, API suite, Tiny Academy, Tiny certification process, education profile)

• Develop funnel strategies from awareness through onboarding, focusing on activation and retention of HCPs and strategic partners

• Optimize our HCP-DTC flywheel to drive downstream patient testing and grow referral-based revenue

Scientific Content & Clinical Education

• Translate complex gut and vaginal microbiome science and clinical research into compelling B2B messaging, webinars, white papers, and sales collateral

• Collaborate closely with science, clinical, and partnerships teams to build educational campaigns that support partner success

• Build a clinical studies marketing toolkit (one-pager, slide, FAQ, and email copy) that clearly communicates opportunities, study pathways, and how partners can work with Tiny Health

• Co-lead thought leadership, newsletter, and content efforts for the HCP community (functional MDs, NDs, nutritionists, integrative practices, concierge medicine) and enterprise clients (health assessment companies, wearables, hormone health companies, wellness brands)

Growth & Performance Marketing

• Run targeted B2B campaigns on platforms like Meta, LinkedIn, Google and via email using tools like Klaviyo or SendGrid

• Work with data & analytics to track campaign performance, attribution, and conversion, optimizing to cost-per-lead and LTV

• Collaborate with sales, partnerships, and operations teams to nurture pipeline and ensure alignment on lead quality

Cross-functional Collaboration

• Work with our partnerships team on go-to-market and co-branded campaigns

• Partner across clinical, D2C marketing, operations, product, and science to ensure brand consistency, product roadmap alignment, and accuracy of scientific translation on clinical marketing collateral

• Manage agency or contractor relationships as needed to support design, copy, or campaign execution

Qualifications

Required

• Have 4+ years in B2B marketing, preferably in healthtech, lab testing, clinical diagnostics, or wellness

• Have worked closely with or marketed to functional medicine, integrative MDs, NDs, or longevity clinics

• Are skilled in scientific communication and can distill complex topics (e.g. gut microbiome, AI insights, metabolomics) into digestible, compelling narratives for healthcare professionals

• Understand the B2B2C dynamic—and know how to leverage HCPs to grow patient volume

• Are comfortable managing campaigns across email, paid media, content, and lifecycle marketing

• Have a solid marketing analytics mindset and know how to interpret funnel metrics, test hypotheses, and optimize for ROI

• Are a strong writer, clear communicator, and thoughtful collaborator

Preferred

• Registered Dietitian or clinical background in nutrition, functional medicine, or microbiome

• Experience with CRMs like Zoho or HubSpot, Klaviyo, Sendgrid, Webflow, Google Analytics, and Ad Platforms (Meta, Google, Linkedin)

• Experience working in a past faced Series A–B stage startup with limited resources and high expectations

• Familiarity with Fullscript, Rupa Health, Evexia or other HCP marketplace platforms

How we work

• A mission that actually pulls people in
  We make the microbiome measurable and actionable at every life stage, and real people write in to say it's life-changing.

• Remote-first, real overlap
  Our FTEs are based in North America and work core hours from 9am–6pm CST, shiftable by up to two hours either way — start at 7am or 11am, wrap at 4pm or 8pm.

• Written first, huddle second, meet last
  Default to a clear Slack post, huddle when a thread stalls, and meet only to make a real decision.

• Fast, but never sloppy
  Do the two-month thing in two weeks, then check the work—shipping errors is rework, not speed.

• Shape what we build, not just how we build it
  There's no playbook waiting for you, so write it—and bring the alternative, not just the objection.

• Day One mentality
  Fewer titles and layers; process is a guardrail where it counts, never the reason something didn't ship.

• No hidden agendas
  Numbers, misses, and feedback are shared openly and in real time, so you always know where you stand.

• High standards, genuinely fun people
  Take the work seriously and ourselves much less—high-performing and fun to be around is the hiring bar.

• Is this pace for you?
  Venture-scaled and on a steep trajectory, with intensity in spikes, fiercely protected flexibility, and faster growth than anywhere else.
