About Unbxd :

Unbxd, part of the Netcore family, is a leading AI-powered eCommerce product discovery platform that enables retailers to deliver intelligent search, personalized recommendations, and seamless shopping experiences.

Our platform processes billions of shopper interactions daily, helping global retailers enhance product discovery, increase conversions, and drive revenue growth.

As Unbxd continues to scale rapidly, we are looking for a Lead Engineer who can architect highly scalable systems, drive engineering excellence, and play a critical role in evolving our AI-driven platform.

Role Overview :

As a Senior Backend Software Engineer, you will build and scale platform services powering search, reporting, integrations, AI workflows, and operational systems at production scale.

You will work at the intersection of distributed backend architecture and AI/agent-driven workflows, ensuring high reliability, observability, and performance across platform services.

This role requires deep expertise in Ruby on Rails, a strong system design mindset, and the ability to drive backend engineering excellence across a fast-moving, startup-style team.

What You Will Do :

• Architect & Develop : Design and build scalable backend services and platform capabilities using Ruby on Rails, with a focus on reliability and long-term maintainability.

• API & Async Engineering : Develop robust RESTful APIs and asynchronous workflows that power integrations, reporting pipelines, and AI-driven features.

• Search & Data Infrastructure : Work on search infrastructure (Elasticsearch/OpenSearch), databases (MongoDB, PostgreSQL), and caching layers to support high-throughput platform needs.

• AI & Workflow Orchestration : Contribute to AI-driven workflows, LLM integrations, and agent-based automation using tools like Argo Workflows and Python-based pipelines.

• Production Reliability : Improve system observability, debug and resolve production incidents, and drive platform performance improvements across services and infrastructure.

• Infrastructure & DevOps : Work with Kubernetes, Docker, and messaging systems (Kafka, NATS, RabbitMQ) to maintain and scale production-grade distributed systems.

• Technical Collaboration : Contribute to architecture discussions, system design decisions, and engineering best practices across the backend team.

What We're Looking For :

• 4 - 5 years of backend engineering experience with a track record on scalable production systems.

• Ruby on Rails Proficiency : Strong hands-on expertise in Ruby and Rails - APIs, background jobs, and large-scale application design.

• System Design Fundamentals : Solid understanding of distributed systems, database design, caching strategies, and async processing patterns.

• Infrastructure Fluency : Practical experience with Kubernetes, Docker, and production infrastructure management.

• Search & Messaging : Familiarity with Elasticsearch/OpenSearch and message brokers like Kafka, NATS, or RabbitMQ is a strong plus.

• AI & Automation Exposure : Experience with Python, LLMs, AI agents, or workflow automation tools (Argo Workflows) is highly desirable.

• Debugging & Ownership : Strong problem-solving skills with a bias for ownership, independent execution, and fast iteration.

Why Join Unbxd?

• Work on backend systems that directly power AI-driven search and discovery experiences for some of the world's largest retailers.

• Solve unique distributed systems challenges at the intersection of platform engineering and AI/ML workflows.

• Be part of a fast-growing product company within the Netcore ecosystem with real ownership and impact.

• Opportunity to shape platform architecture at a rapidly scaling global AI product company.

• Collaborate with high-caliber engineers, ML specialists, and infrastructure experts in a dynamic, builder-first environment.
