Overview of the role:
Flutter Technology is looking for a Site Reliability Engineer to guarantee the stability, uptime, and efficiency of our essential gaming and betting platforms throughout our worldwide operations. This position blends engineering skills with operational proficiency to sustain continuous service availability for millions of users globally via on-call support.
As a member of Flutter Functions, you will work closely with development groups, infrastructure experts, and business partners. Together, you will maintain high-performance, scalable systems supporting our iGaming & Sports platforms in several markets. You will be the expert responsible for building and managing enterprise-level observability, disaster recovery, and business continuity features across our AWS Cloud environment.
The ideal candidate combines strong understanding of SRE protocols with public cloud experience (AWS, Azure, GCP). This ensures our systems maintain high availability, recover rapidly from incidents, and offer comprehensive observability on our platform. You will be responsible for making sure our systems are resilient, recoverable, and subjected to regular fire drills and extensive testing.
You will interact with senior participants during customer concern escalations and post-incident discussions, needing excellent communication abilities to convey technical challenges and operational updates. You should feel confident collaborating with cross-departmental teams in changing environments, working alongside development staff, infrastructure professionals, and business interested parties across various functions and brands.

It also involves implementing solutions that support Flutter's multi-regional, multi-market infrastructure.
This role follows a hybrid approach to working, allowing you to combine working from home with working in our modern offices. These discussions are between you and your manager to find the best pattern for you both, while recognising that quality time together is essential for keeping us mission-aligned.
Our teams work from a lively location nestled within this historic city. Enjoy the best of both worlds with winter and summer offices, tantalizing free snacks, and a gaming paradise for endless entertainment.
