Job description

Why this role exists:

We are growing our AI team and are looking for a Senior AI / Generative AI Engineer to build and operate production-grade LLM-based systems across the platform.

This role focuses on applied Generative AI: internal AI automation, chatbots, AI assistants, and MCP-based services already used in production. You will work on top of an existing ML and data platform, building systems that are reliable, maintainable, and practical to operate.

This is a hands-on engineering role with end-to-end ownership. Not research. Not prompt-only.

What you’ll drive:

Technical Ownership

  • Own LLM-based systems from design to production support.

  • Design architectures for Generative AI systems (RAG, agents, tool/context serving).

  • Make clear trade-offs between quality, latency, cost, and complexity.

  • Set engineering standards for building and operating AI systems in production.

  • Act as a technical reference point for applied GenAI.

Hands-on AI Engineering

  • Build and maintain production LLM-powered systems.

  • Develop chatbots and AI assistants with predictable behavior.

  • Design and implement RAG pipelines (ingestion, embeddings, retrieval, generation).

  • Implement agent-style workflows with tool/function calling.

  • Build and integrate MCP servers or similar context/tool-serving components.

  • Integrate AI systems with backend services and ML infrastructure.

Production & Reliability

  • Design evaluation frameworks for LLM outputs.

  • Monitor LLM behavior, system health, and costs in production.

  • Address performance, scalability, and operational issues.

  • Handle production incidents and contribute to long-term fixes.

  • Design systems with failure modes, fallbacks, and graceful degradation.

What makes you a GR8 fit

Must-have

  • Strong software engineering background.

  • Proven experience building LLM-based systems in production.

  • Hands-on experience with: LLMs and RAG architectures, Chatbots or conversational AI systems, Tool/function calling and agent-style patterns.

  • Experience with context or tool-serving systems (MCP or similar).

  • Experience integrating AI into real-time production products.

  • Understanding of performance, scalability, and cost trade-offs.

  • Cloud experience (preferably AWS).

  • Strong engineering fundamentals (testing, debugging, reviews, observability).

Nice-to-have

  • Multi-agent or workflow-based systems.

  • Fine-tuning or adapting open-source LLMs.

  • ML platforms / MLOps background.

  • Experience operating latency- or cost-sensitive systems.

  • Production incident ownership in AI systems.

Tech Stack:

  • Languages: Python, SQL.

  • LLMs: Amazon Bedrock, OpenAI, Anthropic, open-source models.

  • Frameworks: LangChain, LangGraph, Pydantic, Langfuse.

  • RAG: Embeddings, Qdrant / FAISS / OpenSearch / pgvector.

  • Cloud: AWS (ECS / EKS / Lambda, S3, OpenSearch).

  • DevOps: Docker, Git, CI/CD.

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.

Our culture & core values:

GR8 Tech culture is how we win — through trust, ownership, and a growth mindset. We move fast, stay curious, and keep it real, with open feedback, room to experiment, and a team that’s got your back.
