Staff Platform Engineer

Role Overview

• At Joko, we’re entering a new stage of scale: over half a million active daily users, and zero-downtime expectations. As our Staff Platform Engineer, you’ll shape and lead our platform efforts.
• Infrastructure: Make our production infrastructure more scalable and resilient (runtime reliability, capacity, failure modes), so we can grow fast without compromising stability.
• Monitoring & alerting: Build best-in-class observability (metrics, logs, tracing, SLOs) and an alerting strategy that is actionable, low-noise, and improves incident response and on-call quality.
• Cost & performance: Optimize our architecture to balance reliability, performance, and cloud costs—identify the biggest cost drivers, simplify where it matters, and turn infrastructure efficiency into a measurable business lever.
• Developer experience: Treat our engineering workflows as a product—accelerate CI/CD, releases, environment management and automation, and create “golden paths” that make the right way the easiest way.
• Security baseline: Raise the security bar across infrastructure (IAM, secrets, hardening, security monitoring) with pragmatic solutions that scale with the team and don’t add friction.
• Technical leadership: Define the platform roadmap, align stakeholders, and lead cross-team initiatives end-to-end—bringing structure, standards, and mentorship so platform practices become shared, not heroic.

Requirements

• Production reliability & scale: Strong track record operating and evolving production systems (observability, incident response, scalability, reliability patterns) in environments with real traffic and high expectations.
• DevOps & automation mindset: You consistently improve how engineers ship—CI/CD, releases, automation, tooling—and you care about fast feedback loops and day-to-day developer productivity.
• Cost/performance tradeoffs: You're comfortable making pragmatic architectural decisions that balance reliability, latency, and cloud costs, with a clear focus on impact.
• Security fundamentals: You have solid infrastructure security basics (permissions/IAM, secrets, least privilege, hardening). You don't need to be a full-time security specialist, but you know how to raise the baseline.
• Cloud & modern infrastructure: Experience with AWS (we run a server-less setup) or equivalent; familiarity with IaC and modern deployment patterns is a strong plus.
• Strong software engineering foundations: You're a strong engineer first (design quality, testing, maintainability) and you bring that rigor to platform work.
• Product-minded: Strong sensitivity to user experience, performance metrics, and real-world usage at scale.
• Problem solver: Comfortable working in complex, evolving codebases, with the patience and pragmatism to improve them incrementally.
• Collaboration & influence: You communicate clearly, raise the bar through reviews and mentorship, and partner well with engineers and product stakeholders.
• Languages: Fluent in English, both written and spoken. French is not required.
