Tech Stack (Current) • Frontend: Vue (2 & 3), Nuxt, • Cloud / Delivery: Azure (CI/CD), • Observability: Sentry (and related logging/monitoring patterns) (We don’t expect you to know every tool on day one — we care about fundamentals and ownership.) Life at Keepnet Engineering at Keepnet is about craft, collaboration, and impact. What you can expect: • Hybrid working: In-office collaboration + remote focus time, • Thoughtful engineering: Time to design systems properly, not just ship quickly, • Global context: Work on a multinational platform used across multiple regions, • AI-first environment: AI-assisted development and production-grade AI systems are part of everyday work, • Team culture: Monthly team lunches and quarterly offsites, • Care about clean architecture, maintainability, and product quality, • Enjoy working with experienced peers who challenge each other constructively, • Prefer preventing incidents over reacting to them, • Want to build software used by real customers at real scale, • Believe good engineering is as much about ownership and judgment as it is about code If that sounds like you, we’d love to talk.
