Why This Role Stands Out
This role offers significant impact by letting you own features end-to-end and shape technical direction within a fast-moving team building an innovative marketplace. You'll thrive here if you're a mid-senior engineer eager to leverage React Native, serverless AWS, and AI coding tools to build and optimize a mobile-first product, so apply today!
Quick Overview
Job Description
About the Role
Join a small, fast-moving engineering team building a mobile-first internet marketplace product that brings together AI, real-time pricing, and multi-marketplace infrastructure. You will own features end to end and help shape technical direction, engineering practices, and product quality.
What You'll Do
Build and optimize cross-platform mobile features using React Native and TypeScript.
Design and implement serverless APIs using AWS Lambda, API Gateway, DynamoDB, and RDS.
Write infrastructure as code with AWS CDK or SAM, and deploy the systems you build.
Scope and estimate mid-to-complex features with technical precision.
Review code, establish testing standards, and mentor junior engineers.
Own CI/CD pipelines, observability, and on-call reliability for your services.
Use agentic coding tools such as Claude Code, Cursor, or Copilot for multi-file and architectural work.
What We're Looking For
2 to 5 years of professional software engineering experience, including production mobile or full-stack work.
Strong TypeScript and React Native skills, including experience debugging native bridge issues, optimizing rendering, and delivering polished user experiences.
Solid Node.js and REST or GraphQL API design skills, with serverless architecture experience preferred.
Production experience with AWS, including Lambda, API Gateway, DynamoDB, S3, and IAM.
Experience owning features through scoping, development, deployment, and ongoing maintenance.
Comfort using agentic coding tools as part of your regular workflow and working in a small team where you help create structure.
A bachelor's degree. Marketplace, fintech, data-intensive consumer products, real-time pricing, websockets, or event-driven architecture experience is a plus.
