🎯 WHAT YOU WILL DO

At Joko, we’re entering a new stage of scale: over half a million active daily users, and zero-downtime expectations. As our Platform Engineer, you’ll shape and lead our platform efforts. You’ll be the first senior engineer focused on these topics, building on work currently spread across the team and turning it into a clear, reliable, high-leverage platform that helps everyone ship faster and safer.

- Infrastructure & reliability: Own our production infrastructure end-to-end: resilience, capacity, and cost. You'll make our systems more robust as we grow, simplify where it makes sense, and turn infrastructure efficiency into a real business lever — not just an engineering concern.

- Observability & incident response: Build the visibility layer that lets us catch problems before users do. You'll centralize logs and alerts across our tools, define what "healthy" looks like, and design an on-call experience that's sustainable — clear signals, fast response, no noise.

- Security & access control: Raise the security bar in a way that scales with the team. From access management and secrets handling to compliance work and release hardening — you'll make security a natural part of how we ship, not a checkpoint at the end.
