About us

We're looking for a DevEx Engineer to drive how we build, ship, and run software. This role focuses on making engineering teams faster, more reliable, and better supported through strong infrastructure, smart tooling, and better developer workflows. You'll combine SRE practices, infrastructure design, and a product mindset to improve our engineering systems and culture.

Note: We know this is a wide scope. This role is our starting point for investing in the full DevEx stack. The team will grow, and we don’t expect one person to carry all of this long-term. But if you’re excited by the mission and can drive change across some of these areas, we’d love to talk.

Come join the company that’s transforming the world of mobile gaming by making playtime truly rewarding. At JustPlay, we’re on a mission to build a fairer, more sustainable Play-to-Earn ecosystem—one where players are rewarded for their time, and engagement drives continuous growth. Since launching in 2020, we’ve grown into one of the world’s leading loyalty gaming platforms, with over 25 million downloads and 500,000+ daily active users. Bootstrapped and headquartered in Berlin, our global team spans 19+ countries and is united by a belief in fun, fairness, and meaningful impact. We’re leading a massive shift in the gaming industry—but it’s still early enough for you to make your mark. At JustPlay, you’ll have the freedom to shape bold ideas, elevate our brand, and help tell the story of a company that’s not just growing fast, but growing right.

Tasks

• DORA metrics (Deployment Frequency, Lead Time for Changes, Change Failure Rate, MTTR) are your bread and butter that you’ll use to identify bottlenecks and lead improvements across the SDLC to move the right metrics

• Lead reliability initiatives and system hardening efforts
• Improve on-call experience with better tooling and clear processes
• Support engineering teams during incidents, ensuring smooth communication and technical guidance

• Own CI/CD pipelines and platform services used across teams
• Ensure stability, scalability, and security of shared infrastructure
• Research and recommend developer tools that match real needs and workflows

Requirements

• 5+ years in roles like SRE, DevOps or platform engineering

• Solid knowledge of GCP infrastructure and core services (GKE, IAM, CloudSQL, Pub/Sub, etc.)
• Proficiency in IaC
• Deep understanding of CI/CD systems and deployment pipelines
• Programming experience in Java, although Kotlin is preferred(we just assume the candidate already does Go), ideally with production-grade services or tooling

• Experience evaluating and rolling out third-party tools for developer experience

Mindset

• Curious and systems-oriented, you look for root causes and sustainable solutions
