Engineering Manager - Ruby on Rails

About This Role

This engineering manager role leads the development and operations of a Warehouse Management System (WMS) for a global B2B SaaS enterprise. The platform is critical for managing complex workflows including inventory control, order fulfillment, and omnichannel commerce for brands, retailers, and logistics partners. The manager will drive engineering and quality assurance teams, fostering a culture of outcome ownership and guiding a transition to an integrated, AI-first working model.

Responsibilities

• Ensure predictable engineering output by managing capacity planning, identifying risks early, and executing recovery strategies to meet 90-day commitments with high accuracy and zero delays
• Establish and maintain rigorous standards for code quality, test coverage (including RSpec, integration, and load testing), and deployment frequency
• Directly manage service availability and latency, overseeing incident response and root cause analysis to resolve recurring issues
• Operate within established architectural and security guardrails to protect multi-tenant isolation and system performance
• Monitor and optimize engineering costs related to compute, storage, and AI tooling, ensuring that cost-per-delivered-item and infrastructure expenses trend downward without compromising quality
• Drive the adoption of AI coding assistants (such as Claude Code, Cursor, and Copilot) to shift the team toward spec-driven delivery
• Lead the transition of AI-enabled features, such as intelligent slotting and capacity forecasting, from pilot programs to production-grade solutions
• Manage the full lifecycle of team members, including hiring, performance reviews, and career growth planning
• Engage directly in solution design, prototyping, and complex implementation tasks where necessary to unblock the team
• Partner effectively with the Engineering Head, Product Management, Delivery Managers, and other technical leads to align on priorities, manage technical debt, and ensure smooth go-live processes
• Coordinate with Sales, Customer Success, Implementation teams, and Security groups to manage customer commitments, handle escalations, and ensure release readiness

Requirements

• 9 to 18 years of software engineering background, including a minimum of 4 years in a leadership role managing engineering teams and owning delivery outcomes
• Deep expertise in Ruby on Rails backend development at scale, with strong knowledge of asynchronous processing (Sidekiq/Redis), PostgreSQL performance tuning, and high-throughput system architectures
• Proven experience building distributed, event-driven systems on AWS, including EKS/Kubernetes, ECS, SQS/SNS, EventBridge, Aurora, S3, API Gateway, and Redis
• Strong capability in designing scalable, multi-tenant architectures with robust handling of idempotency, retries, backpressure, and failure scenarios
