GR8 Tech builds B2B iGaming platforms for operators who play to lead.


We deliver full-cycle, high-impact tech designed to scale — from seamless integrations and expert consulting to long-term operational support. Our platform powers millions of active players and drives real business growth. Call it what it is: the iGaming Platform for Champions.


With 1000+ GR8 people across locations and time zones, we don’t just ship technology — we help operators build success stories across brands, markets, and geos.


Our ambition drives us. Our people make it real.


If you’re a challenger in spirit and a champion in action — join us.

Why this role exists:


This role exists to bridge the gap between ambitious business goals and high-performance engineering reality. You’ll help us scale our technical ecosystem by taking full ownership of architectural blueprints, governance standards, and the long-term stability of our distributed systems.


What you’ll drive:


Strategy & Architecture Design



  • Define and evangelize technology principles that balance short-term delivery with long-term system vitality.

  • Architect distributed systems using Domain-Driven Design (DDD), CQRS, and Event-Driven Architecture (EDA).

  • Select and validate the right tools—from Kafka streams to NoSQL stores—to solve specific scale bottlenecks.


Resilience & Governance



  • Design for failure by implementing patterns like Circuit Breaker, Bulkhead, and advanced Rate-limiting.

  • Establish governance frameworks that unblock developers rather than slowing them down with bureaucracy.

  • Optimize data strategies, including sharding, replication, and performance tuning for SQL/NoSQL databases under heavy load.


Delivery & Cloud Evolution



  • Build scalable infrastructure using Kubernetes, Docker, and Infrastructure as Code (Terraform/Ansible).

  • Modernize CI/CD pipelines to ensure automated, secure, and rapid deployments.

  • Drive FinOps initiatives to ensure our cloud architecture is as cost-efficient as it is performant.


Technical Leadership



  • Unblock engineering teams by breaking down complex problems into clear, documented architectural blueprints.

  • Lead architecture reviews and mentor senior engineers to foster a culture of technical excellence.


What makes you a GR8 fit:


Must-have



  • 5+ years in senior/lead engineering roles with a proven track record in Microservices, EDA, and DDD.

  • Deep understanding of CAP theorem, ACID properties, and implementing fault-tolerance patterns.

  • Hands-on mastery of AWS or Azure, including Kubernetes, Docker, and Terraform (IaC).

  • Expert-level SQL/NoSQL knowledge, including database sharding, replication, and query optimization.

  • Proficiency in Kafka (architecture, stream processing, and optimization for reliability).

  • Master’s degree in Computer Science or a related technical field.


Nice-to-have



  • Understanding of IAM, PKI, and building secure VPC/Hybrid cloud environments.

  • Experience with GitLab CI/GitHub Actions and optimizing cloud infrastructure costs.

  • Designing monitoring strategies using APM tools and logging frameworks for full system visibility.

  • Proven ability to migrate monoliths to cloud-native architectures without downtime.

  • Experience in technical mentoring, code reviews, and driving engineering excellence across teams.

Why you’ll love working here: 


Benefits Cafeteria — annual budget you allocate to:


Sports • Medical • Mental health • Home office • Languages.


Work-life & support



  • Paid maternity/paternity leave + monthly childcare allowance.

  • 20+ vacation days, unlimited sick leave, emergency time off.

  • Remote-first + tech support + coworking compensation.

  • Team events (online/offline/offsite).

  • Learning culture with internal courses + growth programs.
