AI Engineer

TLDR

This unique AI Engineer role involves owning initiatives end-to-end on a greenfield project, shaping how AI is utilized across the company's products and services.

About the company: United Tech is a global IT product company shaping the future of real-time social connection. With millions of users across North America, Europe, LATAM, and MENA, we build next-gen mobile and web apps for live-streaming and social networking. Our platforms enable connection at scale fast, interactive, and deeply engaging. The market is projected to exceed $206B by 2030, and we are already leading the evolution. Founded in Ukraine, scaling worldwide About your role: We’re looking for an AI Engineer who wants to build production-grade AI systems, not just experiment with demos. This is a high-ownership, greenfield role where you’ll help build our AI platform from scratch, working directly with the Head of AI.  You’ll own initiatives end-to-end — from discovery and architecture decisions to production delivery — and play a key role in shaping how AI is used across the company. You’ll work with a modern AI stack including Claude/OpenAI/Bedrock, RAG pipelines, eval frameworks (Promptfoo, Ragas, LangSmith), and agentic patterns. This role is ideal for someone who enjoys autonomy, strong engineering ownership, and proactively identifying the next highest-leverage opportunity to drive into production. In this role, you will
  • Design and build RAG and automation workflows inside our VPC environment.

  • Create integrations across engineering, communication, and knowledge-management systems (Jira, Confluence, Slack, Google Drive, Git).

  • Develop AI-powered pipelines for code quality checks, ticket auto-classification, documentation updates, release notes, and meeting summaries.

  • Work on prompt engineering, model selection and routing (Haiku / Sonnet / Opus), and workflow optimization.

  • Build evaluation and regression frameworks for AI workflows to prevent model-upgrade regressions.

  • Create lightweight dashboards for engineering leads to surface delivery patterns and bottlenecks.

  • Own initiatives end-to-end: scope → design → ship → measure → iterate.

It’s all about you
  • 5+ years of production experience with Python (services, async, API integrations, clean and testable code).

  • Hands-on experience with LLM APIs in production: Anthropic Claude (Opus/Sonnet/Haiku), OpenAI, AWS Bedrock.

  • Strong understanding of RAG systems: chunking, embeddings, hybrid search, re-ranking, grounding/citations.

  • Prompt engineering + structured outputs + tool/function calling.

  • Experience with eval/regression frameworks: Promptfoo, Ragas, LangSmith, or custom evaluation harnesses.

  • Agentic patterns: ReAct, function-calling loops, fallbacks.

  • Vector databases: pgvector, Pinecone.

  • Workflow orchestration: n8n, Airflow, or custom orchestration systems.

  • Observability: token-spend tracing, latency monitoring, model routing.

  • Solid AWS fundamentals: IAM, Lambda, S3, CloudTrail — comfortable deploying inside VPC environments independently.

  • CI/CD + pipeline hooks (GitLab/GitHub), webhooks, event-driven architectures.

  • Basic SQL skills for analytical queries and metrics dashboards.

  • Driver mindset: proactively identifies the highest-leverage opportunity and drives it to production

  • B2 English level

  •  


    Would be a plus

    • Real REST integrations with 2–3+ APIs

    • Experience with workflow orchestration tools.

    • Prompt evaluation tooling such as  LangSmith is nice to have

    • Experience with Docker

    • RAG experience: embeddings and vector stores (pgvector, Pinecone, or similar) for knowledge base use cases
