• Work with SQL and NoSQL databases, including data modeling, query optimization, and performance tuning.
• Build and deploy containerized services using Docker.
• Develop automation tools and internal processes to improve product performance, reliability, and efficiency.
• Troubleshoot complex issues across applications, infrastructure, and networking.
• Lead technical solutions and contribute to architecture decisions as part of FAZE's R&D team.

Requirements

• Strong hands-on experience with Python and developing complex, production-grade backend systems.
• Proven experience with Flask, REST APIs, and server-side development.
• Experience building integrations using OAuth 2.0, Webhooks, Tokens, and authentication protocols.
• Strong AWS experience, including cloud architecture, compute, storage, and networking.
• Hands-on experience with Docker and containerized environments.
• Experience with SQL and NoSQL databases, particularly PostgreSQL / MySQL and MongoDB.
• Solid understanding of HTTP/HTTPS, networking, authentication, and service-to-service communication.
• Experience with Git, CI/CD pipelines, testing, and software development best practices.
• Strong system design, debugging, and problem-solving skills.

Nice to Have

• Experience with AWS services such as ECS, Lambda, S3, RDS, and IAM.
• Familiarity with Kubernetes, Microservices, asynchronous processing, message queues, and background workers.
• Experience with browser automation tools such as Playwright or Selenium.
• Experience integrating with GitHub, GitLab, Jira, Confluence, Azure DevOps, or other SaaS platforms.
• Familiarity with AI, LLMs, and AI Agents.
• Background in Cybersecurity or Application Security.
• A relevant degree in Computer Science / Engineering or a background in a military technology unit.

What We're Looking For

• Ownership & Independence: Ability to lead complex projects from concept to production.
• System-Level Thinking: Strong architectural mindset and end-to-end understanding of systems.
• Problem-Solving & Curiosity: Ability to research, learn new technologies, and tackle unfamiliar challenges.
• Proactive Mindset: Initiative, accountability, and a hands-on approach.
• Team Player: Comfortable working in a small, fast-paced, highly technical R&D team.

If you're passionate about building complex systems, solving challenging technical problems, and making a real impact, we'd love to hear from you!
