## About the Role

Do you have experience in Systems engineering?, We're looking for a hands-on Principal Software Engineer who thrives in complex, fast-moving environments and wants to own the technical direction of mission-critical systems.

This is a deeply technical, high-ownership individual contributor role. You'll be the most senior engineer on the platform, responsible for setting architecture, guiding technical decisions, and ensuring both systems stay stable, scalable, and shipping fast.

You should be comfortable operating across backend systems, frontend interfaces, infrastructure, and emerging AI workflows, and you should naturally think in terms of systems, tradeoffs, and long-term maintainability., * 10+ years of professional software engineering experience

 * Deep experience building and operating production systems on AWS
 * Strong expertise in TypeScript / Node.js, with Next.js + React
 * Advanced PostgreSQL experience (schema design, scaling, performance tuning, multi-tenant systems)
 * Strong background in event-driven / distributed systems (queues, async workflows, background processing)
 * Hands-on experience with infrastructure-as-code (Terraform, CDK, or OpenTofu)
 * Proven ownership of systems from architecture through production support / on-call
 * Comfortable actively using AI coding tools (Cursor, Claude Code, etc.) as part of daily development workflow, * AWS: Lambda, Step Functions, ECS Fargate, SQS/EventBridge, RDS, S3, IAM
 * Strong backend engineering in TypeScript/Node.js (primary)
 * Experience working across multiple languages (Go and/or Python preferred)
 * Next.js / React frontend development experience
 * Production-grade system design (scalability, reliability, observability)
 * Experience debugging and optimizing distributed systems, * Experience with Go and/or Python in production environments
 * Exposure to LLM / agentic systems (Bedrock, OpenAI, Anthropic, prompt workflows, evals)
 * Background in retail, inventory, supply chain, or forecasting systems
 * Experience building data-heavy or operational planning tools
 * Prior work in high-scale infrastructure environments (AWS-heavy orgs, large tech companies), * Ability to travel onsite approximately once per month

## Description

* Own technical architecture and system design across two core platforms.
 * Keep production stable and the release cadence fast as the platform grows.
 * Make and document the big calls - what to consolidate, what to harden, what to leave alone.
 * Stand up the things a maturing platform needs: observability, runbooks, and engineering guardrails.
 * Level up the team through code review, pairing, and clear written decisions.
