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

Core 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

Optimize event processing pipelines (SQS → services → Kafka)

Ensure data consistency across distributed systems

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

TypeScript/JavaScript expertise with modern frameworks (React preferred)

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)
