Job Description

In this role, you will go beyond building standard user-facing features to focus on critical internal platform architecture. You will work within a lean, agile team to bridge frontend development with backend systems, transforming how internal engineers interact with, validate, and secure core data pipelines.

Job Responsibility

  • Build and scale developer-facing tools and dashboards from scratch to manage data contracts at the code level
  • Protect downstream systems (like recommendation engines) by implementing code-level guardrails against data incidents
  • Act as a critical accelerator for a tight-knit core team, driving rapid prototyping during an essential discovery MVP phase
  • Balance frontend utility with data engine awareness to deliver seamless internal developer experiences

Requirements

  • Senior-level expertise with a strong background in Platform Engineering rather than strictly feature-based development
  • High expertise in JavaScript
  • Comfortable managing backend tasks and general cloud infrastructure
  • Familiarity with Java and general data engineering practices is a strong plus
  • Familiarity with AI coding assistance tools to optimize development workflows
  • Ability to start immediately
