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: Robust problem-solving skills with a bias for ownership, independent execution, and fast iteration.
