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

- 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

We are looking for a Solution Architect to join our Global (Core) Team. This is a hands-on architecture role: you will design how our platform evolves, own its behavior in production, and drive real improvements in reliability, performance, and scalability. You will work closely with the CTO, Tech Leads of product teams, and the Core Solution Engineer, who turns architecture into reusable libraries and standards.

Tech Stack: PHP 8, Laravel, Go, Vue 3, MySQL / Aurora, ClickHouse, Redis, Memcached, SQS, Kafka, gRPC, Kubernetes, AWS, Cloudflare, nginx.

Context: a multi-tenant platform, a hybrid architecture (Laravel monolith + growing Go services) and an ongoing shift from HTTP to event-driven (Kafka) and gRPC communication.

Your Responsibilities:

1. System Design & Architecture

• Service Boundaries: design systems, define service interactions and domain boundaries.
• Monolith vs Services: decide what stays in the monolith and what becomes a separate service, avoiding a distributed monolith and overengineering.
• Communication & Events: define event flows and rules for sync vs async communication (HTTP, Kafka, gRPC, SQS).
• Multi-tenancy: design config-driven, scalable client configuration without tenant-specific hacks in the core system.

2. Production Health & Troubleshooting

• System Health Ownership: own the behavior of the system in production, participate in incident analysis and find real root causes.
• Metrics-Driven Analysis: analyze latency (p95/p99), error rates, queue lag and retries to understand where the system breaks.
• Stability: fix bottlenecks, reduce queue lag, stabilize critical flows and reduce the number of incidents.
• Data over Opinion: validate decisions with real metrics, not assumptions.

3. Technical Initiatives & Implementation

• Initiatives: drive improvements such as an idempotency layer, reliable async flows, caching and service boundary redesign.
• Prototyping (POC): validate ideas and performance before rollout.
• Critical Code: implement complex parts, create reference implementations and help fix critical production issues.

4. Standards & Governance

• Engineering Standards: define API rules, event structure and versioning, and communication patterns.
• Adoption: introduce standards across teams without blocking delivery and measure their adoption.
• Architecture Review: review architecture-level decisions in code: service boundaries, async flows, DB usage and critical paths. The focus is "Will this break in production?", not code style.
• Authority: enforce architectural decisions and block system-level solutions that harm the platform.

5. Support for Teams

• Unblocking: help Team Leads with complex technical problems and resolve system-level issues.
• Collaboration: work closely with the CTO, who owns final cross-system decisions, and with the Core Solution Engineer on turning designs into shared libraries.

Approximate time split: 25-30% design, 25-30% troubleshooting & analysis, 20-25% implementation / fixes, 10-15% discussions, ~10% reviews.

This role does not include: feature delivery, sprint management or people management.

What We Expect From You

• Experience: 7+ years of commercial backend development, with at least 2 years in an architect, principal or staff-level role designing high-load systems.
• System Design: microservices, monolith and modular monolith; service boundaries; API design (contracts, versioning, backward compatibility).
• Distributed Systems: eventual consistency, idempotency, retries / DLQ, outbox and saga patterns; hands-on experience with Kafka and SQS (or RabbitMQ / NATS).
