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.

About project

The product is redefining post-acute care by replacing fragmented, manual workflows with intelligent AI-driven automation. We help healthcare providers manage patients, not paperwork, by delivering robust throughput and intelligence across clinical, financial, and compliance operations. We are built by experts from Stanford Medicine, UCLA Health, and Amazon.

The Role: 

We are looking for a product-focused Full-Stack Engineer to join our team. You will be a key player in building our system, which involves developing sophisticated APIs that interface with Electronic Medical Records (EMR) and building advanced web-scraping tools for healthcare referral platforms.

This isn't just a coding role; we are looking for an engineer who understands the "Why" behind the "What." You will work in a high-efficiency environment where AI tools (Cursor, Gemini, Claude Code) are part of the daily workflow to maximize output and quality.

Technical Stack

• Frontend: React (Proficient)
• Backend: Go (Primary/Preferred) or Node.js
• Languages: TypeScript (Strongly Preferred)
• Workflows & Scraping: Playwright, Temporal (Airflow experience is a plus)
• Data: EMR website scraping, PDF parsing, and data point extraction
• Architecture: System Design focus; Cloud-native development

What You’ll Do

• Automate Workflows: Design systems that remove data access bottlenecks and automate clinical data entry.
• Build the "Injection Track": Develop and maintain APIs that reliably scrape and sync data from EMRs and referral platforms in real-time.
• Collaborate via Design: Participate in "1s design discussions" to align on architecture before implementation.
• Leverage AI: Use modern AI-assisted development tools (Cursor, Claude Code, LLM wrappers) to build faster and smarter.
• Take Ownership: Move beyond task execution to ownership—meaning you don't just follow instructions; you understand the business context and ensure the solution fits the need.

What We’re Looking For

• 3+ years of experience: You have a solid foundation in full-stack development and have worked on product-level code.
• Communication & Alignment: You understand that "going away and building the wrong thing" is a failure. You prioritize constant "connect" and alignment with the team.
• Problem Solvers: You are comfortable with the "messy" side of data—parsing PDFs, scraping complex websites, and ensuring data reliability.
• AI-Forward: You are already using AI coding tools to 2x your productivity.

Our Culture & Philosophy

• Context is King: We provide clear business requirements and motivation. We expect you to understand the "Why" to build better "Whats."
• Execution Levels: We expect our engineers to operate at an "I do" level—owning the solution from design to deployment.
• Efficient Growth: We value unique perspectives and a proactive work ethic.

We Offer:

• Medical Insurance in Ukraine and Multisport program in Poland.
• Offices in Ukraine (Kyiv, Kharkiv) and Poland (Wroclaw) or Remote.
• Paid vacation, sick leaves, and official holidays.
• Legal & Accounting services.
• The company provides all necessary equipment.
• English classes and Education reimbursement.

Some roles let you pick one platform. This one lets you own them all.

Massive is a fast-growing proxy and AI data infrastructure company. Our Monetization SDK powers millions of users across desktop, mobile, and smart TV — and we're looking for a Senior SDK Engineer to own it.

This isn't a ticket-driven maintenance role. You'll make real architectural decisions, ship across four platforms, and directly impact how millions of users experience our core product. Small team, high ownership, no layers between you and the work that matters.

Responsibilities

✔ Maintain and enhance our existing SDKs across Android/FireOS (Kotlin), Tizen/WebOS (JavaScript), Windows (C++), and iOS (Swift).

✔ Develop new features and capabilities based on business requirements and partner feedback.

✔ Collaborate with backend, infrastructure, and product teams to improve SDK performance, reliability, and user experience.

✔ Research and implement optimizations to minimize resource consumption while maximizing efficiency.

✔ Design and implement robust testing strategies for multi-platform SDK releases.

✔ Create and maintain comprehensive documentation for internal teams and external partners.

✔ Investigate and resolve complex platform-specific issues across different operating systems and devices.

✔ Drive architectural decisions for SDK design patterns and cross-platform compatibility.

Requirements

✔ 4+ years of experience in software engineering with a focus on SDK or library development.

✔ Proficiency in at least one primary language: Kotlin (strongly preferred), JavaScript, or C++ — with willingness to learn others.

✔ Experience with mobile and/or TV platform development.

✔ Strong understanding of memory management, threading, and performance optimization across platforms.

✔ Experience with SDK distribution mechanisms (package managers, build systems, dependency management).

✔ Strong debugging and troubleshooting skills across multiple environments.

✔ Self-directed and comfortable working in a fast-paced startup environment.
