We're looking for a Growth Manager to join the team behind Eney, a brand-new AI product just beginning its journey to market.

Eney is designed to change how Mac users interact with their devices. It helps them stay organized, automate routine tasks, and focus on what matters most — and it's currently moving from preview into general availability.

As a Growth Manager, you'll own the conversion and activation layer of the funnel — from the moment a user lands on our page to the moment they become an engaged user of the product. You'll design and run experiments, identify friction points in onboarding and monetization flows, and partner closely with Product, Analytics, and Marketing to move the metrics that matter. The work you do here will directly shape how people discover, try, and stick with Eney.

If you're energized by the idea of working on something new, moving fast, and seeing your decisions reflected directly in the numbers — we'd love to hear from you.

In this role, you will:

• Conduct a full-funnel audit of Eney's onboarding, monetization, retention and acquisition flows to identify leakage points and tracking gaps in partnership with Analytics
• Design, instrument, and run A/B tests focused on onboarding optimization and pricing/packaging variations — establishing baseline conversion metrics and clear test readouts
• Own landing page conversion rate: analyze session recordings, identify friction, propose and ship improvements
• Propose and launch structured monetization tests — bundle offerings, localized pricing variants, win-back campaigns — and measure lift on ARPU
• Partner with Marketing and Product to deploy automated onboarding sequences and churn intercept triggers based on user behavioral segmentation
• Contribute to revenue forecasting — tracking growth levers, modeling the impact of experiments, and aligning on targets with the team
• Bring a hypothesis-driven mindset to every test: write clear specs, define success criteria, and present readouts — including what didn't work and what you learned

Skills you'll need to bring:

• 3–6 years in growth, product, or marketing analytics roles — with hands-on ownership of conversion or activation outcomes
• Experience in B2C SaaS, e-commerce, or AI/productivity products
• Proven experience running A/B tests end-to-end: from hypothesis to instrumentation to readout; familiarity with tools like Growthbook, Optimizely, Adobe Target, or Split.io
• Comfortable with product analytics, funnels, cohorts, and basic statistical concepts — you can write a clear experiment spec and sanity-check your own data
• Experience with pricing and purchase flow optimization — understanding what drives conversion and how to test your way to the right price
• Strong collaboration skills across product, analytics, and marketing; comfortable working with distributed teams across time zones
• Upper-Intermediate English

As a plus:

• Exposure to subscription or freemium monetization models
• Familiarity with AI tools for automating growth workflows

About Evestar
Evestar is an eCommerce marketing agency working with DTC brands, mostly in the US. We cover performance marketing, email and SMS, creative and technology, so retention here works hand in hand with paid media, creative and analytics rather than in a silo.

The role
You'll own email and retention for several eCommerce brands, from planning to building, launching and reporting, and you'll also help prepare creatives for their paid ad campaigns. You'll work with clients directly and be the person they trust with their email program.
Klaviyo is our main platform: almost all of our clients run on it, and only occasionally a brand uses a different email service.

What you'll do
- Build and optimize Klaviyo flows: welcome, abandoned cart and browse, post-purchase, winback and more
- Plan monthly campaign calendars and run campaigns end to end
- Prepare creatives for paid ad campaigns (Meta and other channels): concepts, copy and briefs for designers, together with our paid media team
- Set up segmentation and personalization to grow repeat purchases and revenue per recipient
- Analyze flow and campaign performance and turn the numbers into clear next steps
- Present results on client calls and propose what to test next
- Manage several accounts in parallel
- Use AI tools every day for research, copy, creative and analysis

What we're looking for
- 1,5+ year of hands-on experience with Klaviyo or a similar email platform (Omnisend, Mailchimp, HubSpot or similar): you've built flows and campaigns yourself. Klaviyo experience is preferred
- Experience in eCommerce email, retention or lifecycle marketing
- Solid understanding of email and eCommerce metrics: open and click rates, conversion, revenue per recipient, repeat rate, LTV
- English C1: confident on client calls and in writing
- Organized and able to work independently across multiple accounts
- Comfortable using AI tools in your daily work

Nice to have
- Experience preparing ad creatives for Meta, TikTok or Google
- Shopify experience
- SMS marketing (Klaviyo SMS, Postscript, Attentive)
- Design skills in Figma
- Agency background or experience with US eCommerce brands

Working hours
9:00–17:00 Eastern Time (Miami / New York), which is 16:00–00:00 Kyiv time or 15:00–23:00 Central European Time. Our clients and calls are in this time zone.

What we offer
- Fully remote, full-time, long-term role
- US eCommerce brands and real ownership of your accounts
- Close work with our paid media, creative and other teams
- Compensation based on experience

How to apply
Send your CV and, if you can, an example of a flow or campaign you built: a screenshot or a short description with results.

Please also mention your availability to work US Eastern Time.
