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.

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).
• Databases: relational DB design, indexing, transactions and isolation levels (including money operations), zero-downtime schema changes, replicas, partitioning and sharding.
• Performance & Scaling: caching strategies (Redis, CDN), bottleneck analysis, horizontal scaling and safe profiling in production.
• PHP & Go: deep knowledge of Laravel internals (queues, DI, structure) and practical experience with Go service architecture.
• Infrastructure & Observability: Kubernetes, nginx, load balancing and request flow; logs, metrics and tracing (Sentry, New Relic, Grafana or similar).
• Reliability: designing for failure, fallback strategies and safe deployment strategies (rolling, blue-green, canary).
• DDD: practical understanding of bounded contexts and domain separation.
• Trade-off Thinking: ability to balance complexity vs speed, cost vs performance, flexibility vs simplicity.
• Communication: ability to align multiple teams around technical decisions and explain them to both engineers and business.
• English: B1 (Intermediate) or higher.

It Will Be a Plus

• Domain: experience in iGaming, fintech or payments.
• Multi-tenant SaaS: experience designing platforms for many clients with tenant isolation.
• Analytics: experience with ClickHouse or other analytical databases and OLTP to analytics data pipelines.
• Edge & Cloud: experience with Cloudflare (WAF, CDN, DDoS protection) and AWS architecture.
• Migrations: experience migrating from a monolith to services or introducing event-driven architecture.
• Frontend Architecture: understanding of SPA to SSR migrations and micro frontend trade-offs.
• AI-Assisted Workflow: experience with AI coding tools. We welcome a smart approach to AI to streamline complex tasks, from architectural design to documentation, development, and code refactoring.

What we offer

We believe that a happy team builds the best products. Here is how we support you:
