Job description

Are you a Senior Engineer who wants to define the front-end architecture for the next decade-and use a cutting-edge AI stack to do it? I am partnering with a specialist software vendor that is currently building the next generation of its global enterprise platform. This isn't just another "feature-factory" role; we are looking for a foundational Senior Front End Engineer to lead a greenfield transition across web and mobile, establishing the patterns and standards that will scale for years to come. The Role: Architecture + Innovation Reporting directly to the CTO, you will own the front-end strategy. You'll be designing a robust, scalable architecture using React and React Native, but with a modern twist: you will be expected to lead the charge on AI-driven development. We want someone who leverages tools like Claude Code, GitHub Copilot, and Figma Make to accelerate delivery without sacrificing an ounce of engineering discipline. What you'll be doing:

  • Lead Architecture: Design and implement a modern front-end ecosystem for both web (React) and mobile (React Native).
  • AI Orchestration: Define the guardrails for AI-assisted coding-identifying where LLMs add value and where traditional, high-grade engineering discipline is non-negotiable.
  • High-Stakes UX: Translate complex, data-heavy B2B workflows into clean, ultra-efficient interfaces where speed and clarity are more important than "visual flair."
  • Technical Authority: Act as the internal expert, mentoring other engineers and establishing standards for code quality, testing, and documentation.
  • Rapid Prototyping: Use modern AI prototyping tools (e.g., Google Stitch, Code-to-Canvas) to iterate on UI concepts at pace.

Requirements

  • SME Software Pedigree: You've worked in a small-to-medium software vendor before. You thrive in "all-hands-on-deck" environments where you seek out context, not just requirements.
  • React & React Native Mastery: 5+ years of production-grade experience, with a deep understanding of state management (Zustand/Redux) and API integration.
  • AI Enthusiast: You are already using LLMs to drive your productivity and are excited about evolving engineering workflows through AI.
  • Product Mindset: You don't just write UI code; you want to deeply understand the business domain and customer workflows to build better outcomes.
  • Resilience: You are comfortable operating in a high-impact team where uptime and operational reliability are critical.

Bonus Points for:

  • Experience in Logistics, Aviation, or Enterprise SaaS.
  • Exposure to WebSockets, real-time systems, or Native Android development.
  • A background in C#, Python, or SQL., If you are a self-motivated engineer who focuses on outcomes over activity, apply today.

About the company

This is a rare opportunity to join a stable, successful company at the start of a massive technical evolution. You will have the autonomy to choose the tools, set the standards, and play a foundational role in shaping the future of the platform.
