About the role

  • Implement and design the technical architecture of the Core Technology innovation platform, with AWS as the primary cloud provider and Cloudflare as the edge/runtime layer, supporting rapid FIT team prototyping.
  • Design a lightweight, modular, technology-agnostic architecture that makes it easy to stand up and tear down per-FIT or per-experiment environments using Supabase, N8N, and other managed services.
  • Define simple, reusable “patterns” for common experiment types (e.g., workflow automations, API-based services, small web apps, data-backed prototypes) that minimize boilerplate for FIT teams.
  • Favor managed or packaged services and opinionated defaults over bespoke frameworks, to keep the platform small, easy to evolve, and quick to learn.
  • Be a highly hands-on engineer: prototype, build and iterate on the platform orchestrator, environment provisioning, deployment automation, and integration with identity and networking.
  • Continuously scan and experiment with new tools, frameworks and services relevant to FIT needs (e.g., new workflow engines, BaaS options, edge runtimes, AI/LLM frameworks).

Requirements

  • Bachelor’s degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience.
  • Strong experience in software, platform or cloud engineering roles, with substantial hands-on work building on public cloud (preferably AWS).
  • Strong experience in senior/principal/staff engineer roles owning architecture and delivery of complex or multi-team platforms or systems.
  • Deep experience designing and operating cloud-based platforms and services on AWS (networking, security, compute, storage, IAM).
  • Strong background in containerized, serverless and/or edge-native architectures (e.g., Docker, ECS/EKS, Lambda, Cloudflare Workers).
  • Hands-on experience with infrastructure-as-code (e.g., Terraform) and CI/CD pipelines, ideally in environments that favour rapid iteration and experimentation.
  • Practical experience with one or more of Supabase (or similar BaaS), N8N (or similar workflow automation tools), and Cloudflare (or comparable edge/CDN platforms).
  • Familiarity with LLMs and/or agentic AI frameworks, including how to integrate them into secure, observable systems, is a plus.
  • Strong understanding of security and compliance fundamentals and how to encode them into platform patterns and templates rather than manual processes.
Benefits
  • Health insurance
  • Paid time off
  • Flexible working hours
  • Professional development opportunities
