The posting

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
  • 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

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
