About the role

We're building a performance marketing team, and this role is central to how we grow — owning conversion rates across all marketing touchpoints and the full user journey from first page view to first paid session. You'll work at the intersection of marketing, product, and engineering to generate, test, and scale ideas that move our core metrics: conversion rate, new clients, and CAC.

Responsibilities

• Own conversion performance across all marketing surfaces: main website, blog, landing pages, campaign funnels, and any new acquisition flows.
• Generate, prioritize, and execute CRO hypotheses — from ideation through briefing, prototyping, A/B testing, analysis, and implementation of winning variants.
• Design new funnels for paid channels (Meta, TikTok, and others as we scale), including concept, user flow, messaging framework, and success criteria. Coordinate execution with design, content, and engineering teams.
• Own the post-click experience for all paid traffic — ensure that what happens after a user clicks an ad is optimized for conversion, not just for traffic volume.
• Create and optimize landing pages for campaigns, audiences, and channels — working with designers and developers or using no-code/AI tools where appropriate.
• Monitor and analyze funnel performance at every stage (page view → authorization → first therapy created → first purchase). Identify drop-off points, diagnose root causes, and act on them.
• Run a continuous experimentation process: maintain a hypothesis backlog, manage test calendars, ensure statistical rigor, document results and learnings.
• Write clear briefs and technical specs for product and engineering teams. Communicate the goal, the hypothesis, the expected impact, and the success criteria for every initiative.
• Collaborate with the product team on the authorization-to-purchase flow. Currently owned by product — this role progressively takes over the marketing lens on this funnel, working jointly to improve it.
• Collaborate with the UA/paid channels manager on campaign-to-conversion alignment: ensuring ad creative messaging matches landing page experience, and that conversion signals are properly tracked.
• Participate in tracking and attribution setup alongside analytics — flag data gaps, validate conversion events, ensure the team can trust the numbers.
• Report regularly on conversion metrics, experiment results, and impact on new clients and CAC.

Requirements

• 3+ years in growth marketing, CRO, or a similar experimentation-driven role in a product company (marketplace, SaaS, subscription, or similar).
• Proven track record of improving conversion rates through systematic testing — not just ideas, but shipped experiments with measurable results.
• Strong understanding of user funnels, landing page best practices, and conversion psychology.
• Ability to write clear briefs, create wireframes or prototypes (even rough ones), and articulate what needs to be built and why.
• Hands-on experience with A/B testing tools (Google Optimize, VWO, Optimizely, or built-in product experimentation).
• Comfortable with analytics tools (GA4, Mixpanel, or similar) — able to pull data, interpret funnel reports, and make decisions based on evidence.
• Understanding of event-based tracking: how user events and parameters work, how they trigger flows, and what breaks when tracking is misconfigured.
• Strong cross-functional communication skills — this role lives between marketing, product and engineering daily.
• Structured thinking and ability to prioritize based on expected impact vs. effort.

Nice to have

• Experience with mental health, wellness, or other sensitive/high-trust products where aggressive conversion tactics don't work.
• Experience creating funnels for Meta Ads or other paid social channels specifically.
• Familiarity with no-code tools for landing pages
• Understanding of paid acquisition economics (CAC, LTV, ROAS) and how CRO improvements cascade into unit economics.
  
  What we offer:
• An opportunity to work on a health tech product that improves people’s mental well-being worldwide;
• Flexible schedule and full remote work- no strict location requirements;
• A team of passionate professionals who love what they do and foster an open, supportive atmosphere where every idea is heard and creativity is encouraged;
• Fully remote work with an option to visit our cozy office in Kyiv;
• Competitive compensation, based on your qualifications and experience;
• Paid time off 33 days per year (including public holidays);
• Paid sick leave  10 working days per year;
• Budget for learning and development;
• Paid mental health leave (5 working days per year)

About the role

We're building a performance marketing team from scratch, and email is a core channel for retention, reactivation, and lifecycle communication. This role owns all email communication across the company — transactional, marketing, and campaign-based — and works at the intersection of marketing and product to create a seamless user experience across web and mobile.

Responsibilities

• Full ownership of the email channel: strategy, execution, and performance across all communication types (transactional, broadcast, campaign, lifecycle flows).
• Design, build, and optimize automated flows and trigger-based sequences across the full user lifecycle — from onboarding and activation through engagement, re-engagement, and win-back.
• Develop segmentation strategies based on user behavior, product usage signals, and audience attributes to increase relevance and channel efficiency.
• Run systematic A/B tests on subject lines, content, timing, frequency, and flow logic. Formulate hypotheses, execute tests, and implement learnings.
• Work with users that enter the funnel (e.g., blog subscribers, quiz completions) but don't convert — build nurture sequences to move them toward action without aggressive frequency, respecting the sensitive nature of the product.
• Collaborate closely with the product team to ensure email communication is aligned with what's happening in the product (web + app), reflects the brand's tone of voice, and functions as part of a unified system rather than a siloed channel.
• Collaborate with the communications team, designers, and copywriters on email content. This role is the owner and final decision-maker on what gets sent, when, and to whom.
• Own email content creation and ideation — propose new campaigns, communication angles, and lifecycle touchpoints.
• Manage deliverability: domain health, sender reputation, spam rate monitoring, list hygiene.
• Build and maintain regular reporting on channel performance — open rates, CTR, conversion, unsubscribe rates, revenue attribution per flow.

For discussion: Participate in designing churn prevention flows triggered by product usage signals (e.g., no session booked in X days). Email is a secondary channel here — the logic and triggers will be defined jointly with the product team, but execution in email sits with this role.

Requirements

• 3+ years of experience in email marketing in a product company (SaaS, marketplace, or subscription-based product/edtech).
• Hands-on experience building automated flows and trigger-based campaigns in a marketing automation platform (experience with Customer.io is a strong plus).
• Strong understanding of user lifecycle stages and how email fits into the broader marketing and product funnel.
• Understanding of event-based triggers and audience parameters — ability to think in terms of "if user did X and didn't do Y within Z days, then…"
• Experience with segmentation, personalization, and A/B testing at scale.
• Solid grasp of email deliverability fundamentals (domain authentication, warm-up, list hygiene, spam triggers).
• Analytical mindset — comfortable working with data, interpreting metrics, and making decisions based on test results.
• Attention to detail, ownership mentality, and ability to work autonomously.

Nice to have

• Experience in health, wellness, or mental health products.
• Understanding of sensitive product communication — where intensity ≠ quality and user trust is paramount.
• Experience working with cross-functional teams (product, design, content).
• Familiarity with analytics tools (Mixpanel, GA4, or similar).
  
  What we offer:
• An opportunity to work on a health tech product that improves people’s mental well-being worldwide;
• Flexible schedule and full remote work - no strict location requirements;
• A team of passionate professionals who love what they do and foster an open, supportive atmosphere where every idea is heard and creativity is encouraged;
• Fully remote work with an option to visit our cozy office in Kyiv;

• Paid time off 33 days per year (including public holidays);
• Paid sick leave 10 working days per year;
• Budget for learning and development;
• Paid mental health leave (5 working days per year).

● Implement input handling systems such as touch, pointer events, and device orientation
with low-latency feedback
● Optimizing a high-performance rendering pipeline using Canvas 2D and WebGL to
achieve consistent performance and smooth frame rates on mobile browsers

Across the stack:
● Write unit, integration, and browser-based tests to ensure reliability
● Contribute to technical documentation and internal tooling
● Work closely with product, design, and engineering teams to ship features end-to-end

Core requirements
● Strong experience with Node.js, React, and MongoDB
