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
