Unybrands was established in 2020 by a group of partners united by a shared vision: to build the leading next-generation e-commerce platform for micro-brands. Headquartered in Miami, the company has a global presence with teams in Berlin, London, New York, and China.
Unybrands acquires e-commerce businesses that sell both on and off Amazon. Once acquired, these brands are integrated into Unybrands' platform, where operations are optimized, business performance is enhanced, and expansion into new product lines and markets is driven. Currently we have acquired 30 brands including Pet Care, Personal Care, Home Care, Supplements, Baby & Juvenile, Garden & Outdoor, Sports & Fitness, and Home, Lifestyle Culinary & Arts. Through expert management and robust infrastructure, Unybrands empowers e-commerce brands to scale and thrive.
About the Role
We\'re looking for one of our first senior engineers to help build our event-driven e-commerce platform. We\'re not just building integrations - we\'re using these connected systems to create applications that give us operational advantages over competitors. Think internal tools that help us move inventory faster, predict demand better, and operate leaner than traditional e-commerce companies.
This is a unique opportunity for someone with strong distributed systems experience who can work across our entire stack - from high-performance backend services to modern React applications.
We need engineers who understand message-driven architectures at their core and can apply these principles whether they\'re building in Rust, TypeScript, or Python. If you don\'t know Rust yet but have deep experience with distributed systems in other languages, we\'ll support your learning journey.
What Makes This Role Unique
* Platform founding team: Shape architecture decisions from day one of our new platform
* Business impact: Build tools that directly improve operations and competitive advantage
* Distributed systems at scale: Build event-driven systems processing millions of events daily
* Full-stack ownership: Own features from PostgreSQL to React UI
* Modern tech stack: Rust (or willingness to learn), TypeScript/React, AWS cloud-native
* Real complexity: Handle eventual consistency, message ordering, and multi-tenant isolation
Responsibilities
Backend (60-70% of your time)
* Design and implement message-driven microservices
* Build integration connectors for external APIs (marketplaces, ERPs, logistics)
* Handle complex async workflows with proper error recovery
Frontend (30-40% of your time)
* Build React/TypeScript applications for internal operations teams
* Create dashboards for monitoring integration health and data flows
* Implement real-time updates using event-driven patterns
* Design UI components that handle async states gracefully
* Build tools that help teams make faster, data-driven decisions
Required Experience
Non-Negotiable Requirements
* 5+ years software development with production systems
* Strong distributed systems experience with message-based architectures
* Production experience with at least one of: Kafka, RabbitMQ, SQS, EventBridge, Pulsar
* Understanding of distributed systems patterns: event sourcing, CQRS, saga pattern, eventual consistency
* SQL database experience with complex data modeling
* API integration experience with third-party systems
Technical Skills
* Must have: Message queues, event-driven architecture, async programming, REST APIs
* Backend: Strong experience in any modern language (Go, Java, C#, Python, Node.js). Rust experience is a plus, willingness to learn required
* Frontend: React with hooks, or any of the modern alternatives with willingness to switch
* Database: PostgreSQL or similar RDBMS
* Cloud: AWS services (SQS, EventBridge, Lambda, EKS)
What You\'ll Build
* Event processing pipelines handling out-of-order messages and retries
* State machines for complex multi-step workflows
* API clients with circuit breakers and rate limiting
* React applications with real-time data updates
* Monitoring and observability for distributed systems
* Internal tools that provide competitive advantages
* Automation that eliminates manual operations work
Ideal Candidate Profile
You\'re someone who:
* Has built and operated distributed systems in production
* Understands the trade-offs between consistency and availability
* Can debug issues across multiple services and message queues
* Writes frontend code that handles distributed system realities (eventual consistency, partial failures)
* Is excited to learn Rust if you don\'t know it already
* Can context-switch between backend services and React UI
* Backend: Rust (Axum, Tokio, SQLx)
* Frontend: React, TypeScript, Tanstack Router, Tailwind CSS
* Events: AWS SQS, EventBridge, Kafka
* Database: PostgreSQL with SQLx migrations
* Infrastructure: AWS EKS, OpenTofu/Terraform, ArgoCD
* Current scale: 50-100 events/second, scaling with growth
