Description
Crossian is a high-growth technology-driven e-commerce business. As a start-up formed in 2020, we have created a fast-paced and dynamic environment, enabling our people to reach a cumulative average growth rate of over 1000% in the last 5 years.
We're forming an elite Fullstack squad that operates differently, working with AI-driven products. No "that's not my ticket" culture. Each engineer owns a feature end-to-end - from data model to UI pixel - and thinks like a Product Owner when scoping, like a Solutions Architect when designing, and like a craftsman when coding.
If you want to work with people like that and become like them, this is the next step.
What you'll do
Feature ownership
- Take a feature from kick-off to production: data model, API design, service layer, UI.
- Own reliability, performance, and observability of what you ship - not just the happy path.
- Turn product goals into concrete technical specs.
System design & architecture
- Design full-stack architectures: databases, APIs, queues, caches, frontend rendering strategies.
- Apply patterns (Clean Architecture, Event - Driven, etc) where they fit the problem.
- Write design docs and lead technical discussions.
Backend
- Build well-tested APIs and microservices in Node.js, Go, or Python - whichever fits.
- Design and optimize relational and non-relational databases.
- Work with event streaming.
Frontend
- Build fast, accessible, SEO-friendly storefronts with React / Next.js (SSR/CSR as appropriate).
- Optimize Core Web Vitals, bundle size, lazy loading, and CDN strategy (Cloudflare, AWS S3).
- Write maintainable state management (Redux, Zustand, Recoil).
Code quality & collaboration
- Write clean, tested, well-structured code; review teammates' code.
- Treat unit/integration/e2e testing and CI/CD as standard practice.
- Work with Product and Design to shape requirements, not just receive them.
- Support junior engineers
