We are looking for a Full Stack Engineer to join our team for a long-term project.

Project

A SaaS-based, data-driven eCommerce platform built on AI-powered, fully cloud-native technology for the North American market.

Responsibilities

• Build and own services across the pipeline — ingestion API, validation, stream processing, adapters, serving API.
• Build the UI layer — dashboards and embedded analytics — on top of the data you modelled.
• Make it operable: idempotent ingest and replay, deduplication, provenance, tracing, data-quality checks, tenant isolation, GDPR handling.
• Use AI coding tools to improve development productivity, code quality, debugging, and testing.
• Apply AI-assisted development practices while maintaining established coding standards and version control processes.

Required Skills and Experience

• 5+ years building production backend services and the web UIs on top of them.
• Strong in at least one backend language (TypeScript/Node, Python, Java/Kotlin, or Go) and comfortable in modern JavaScript/TypeScript on the front end (React or similar).
• Real experience with event-driven systems: message queues or streams (Kafka, Pub/Sub, Kinesis), schema evolution, at-least-once delivery, idempotency.
• Solid SQL and data modelling — you can design a warehouse schema and reason about why an aggregate is wrong.
• Cloud-native delivery: containers, CI/CD, infrastructure

• You care about data correctness and can explain a metric's definition to a non-engineer.

   

Nice to Have

• Azure (also GCP/AWS — we're multi-cloud by design).
• Looker or another semantic/BI layer, embedded analytics.
• Clickstream or product analytics work: beacons/tags, sessionization, attribution models.
• E-commerce, search, recommendations, or merchandising domain experience; Shopify integrations.
• Privacy and compliance work (GDPR, SOC 2).

We Offer

• Full-time remote position
• Long-term project
• Opportunity to work with modern cloud-native and AI-powered technologies
• Friendly and professional international team
