Job Description

Senior Engineer for AI-driven development at Fingermark, supporting customer solutions in QSR sector. Focused on modern software development and technical leadership within the Supersonic team.

Responsibilities:

  • AI-Augmented Development: Leading the team in adopting agentic coding workflows (like Claude Code and Copilot Workspace) to increase velocity without sacrificing stability
  • Architecting for Resilience: Building self-healing application architectures on GCP that can proactively manage edge-case failures at the kiosk level
  • Edge Excellence: Deploying and managing high-performance React/Node apps to ChromeOS devices at the edge, ensuring they are snappy and reliable
  • Rapid Prototyping: Turning "what if" into "here it is" by using AI tools to quickly spin up new features and opportunities for our customers
  • Technical Leadership: Conducting peer reviews that focus on architectural integrity, ensuring that AI-generated code meets our high standards for security and scalability
  • L3 Support: Assisting with high-level troubleshooting (with extra compensation for on-call) to keep the world’s kiosks humming

Requirements:

  • The AI Edge: You’re a power user of modern AI coding tools. You don’t just use them for snippets, you use them for multi-file refactors and autonomous debugging
  • GCP Pro: Extensive experience with Google Cloud Platform (Cloud Run, Firestore, Pub/Sub, etc.). You know your way around GCP like the back of your hand
  • The Stack: A specialist in ReactJS and Node.js (both with TypeScript). You love clean, type-safe code
  • Edge Focus: Experience deploying to hardware at the edge, specifically Google ChromeOS or similar locked-down environments
  • Architectural Mindset: You think in terms of "self-healing." You’ve built systems that can recover from network drops or service outages without human intervention
  • Infrastructure as Code: Experience with Pulumi or Terraform to keep our GCP environments consistent and reproducible
  • Polished UI: You care about the "feel." Experience with Tailwind, Framer Motion, or specialized data visualisation (D3) is a huge plus
  • Mentorship: You enjoy levelling up the devs around you and sharing the latest "pro tips" on how to get more out of our AI toolchain

Benefits:

  • Competitive salary and benefits
  • Ongoing professional development and career growth opportunities
  • A supportive, dynamic environment that values balance and wellbeing
