Job description

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 design, build, and operate production-grade AI agent infrastructure and services on AWS. The engineer will establish robust agent orchestration, secure tool execution, and reliable runtime controls to support scalable LLM-powered systems.

What You’ll Drive

Agentic AI Platform Engineering

• Design, build, and operate production-grade AI agent infrastructure.
• Develop agent orchestration, stateful workflows, and durable execution.
• Implement reliable agent execution, checkpointing, retries, and failure recovery.
• Build MCP-based integrations and secure tool execution.
• Develop reusable platform components, APIs, and SDKs.

Production & Reliability

• Design scalable, fault-tolerant AI services on AWS.
• Implement LLM gateways, model routing, fallbacks, and cost controls.
• Build observability, tracing, and evaluation for agentic workflows.
• Optimize performance, latency, scalability, and infrastructure costs.
• Own technical solutions from architecture to production support.

Security & Governance

• Implement authentication, authorization, and access controls for agents and tools.
• Integrate human-in-the-loop approvals and execution safeguards.
• Establish engineering standards for secure and reliable AI systems.

What Makes You a GR8 Fit

Must-have

• 5+ years of software engineering experience with strong Python backend expertise.
• Proven experience building and operating LLM-powered systems in production.
• Hands-on experience with agent orchestration frameworks (LangGraph, or similar).
• Practical experience with LLM APIs, tool/function calling, and agentic workflows.
• Strong understanding of distributed systems, asynchronous processing, and fault tolerance.
• Experience with Python type safety, data validation, and schema management (Pydantic or equivalent).
• Experience with cloud infrastructure (preferably AWS), Docker, and CI/CD.
• Understanding of API security, authentication, and authorization.
• Strong engineering fundamentals: system design, testing, debugging, and observability.
• Ability to independently design, implement, and operate complex technical components.

Nice-to-have

• Production experience with LangGraph and LangChain.
• Experience with MCP servers, clients, gateways, and tool integration infrastructure.
• Durable workflows, checkpointing, and distributed state management.
• LLM gateways, model routing, caching, and inference optimization.
• Agent evaluation, tracing, and observability (MLFlow, Langfuse, OpenTelemetry).
• Kubernetes (EKS), event-driven architectures, and platform engineering.
• Agent security, sandboxing, and human-in-the-loop workflows.
• RAG architectures and vector databases.

Tech Stack

• Languages: Python, SQL
• AI & Agents: LangGraph, LangChain, Pydantic, MCP
• LLMs: Amazon Bedrock, Anthropic, OpenAI
• Observability: Langfuse, OpenTelemetry, CloudWatch
• Cloud: AWS (EKS, Lambda, S3, SQS, IAM)
• Infrastructure: Docker, Kubernetes, GitLab CI/CD
• Integrations: REST APIs, OAuth 2.0, event-driven systems
