Job description

We're looking for an AI Engineer to design, build, and ship agentic AI systems end-to-end - from early prototypes to production deployments.

You'll work closely with the founder and early collaborators, owning meaningful parts of system architecture, agent design, evaluation, and delivery.

This is a builder role, not research-only and not prompt-only.

What You'll Do

Build agentic AI systems

  • Design and implement AI agents that reason, plan, and act across tools, APIs, and data sources
  • Build multi-step workflows (ReAct-style, tool-calling, retrieval-augmented agents)
  • Integrate LLMs into real operational systems (not just chat UIs)

Own systems in production

  • Ship AI systems that are observable, debuggable, and reliable
  • Design evaluation frameworks to measure agent quality, failure modes, and regressions
  • Balance autonomy, control, cost, latency, and risk in real deployments

Applied AI engineering

  • Design retrieval pipelines (RAG), embeddings, vector search, and hybrid approaches
  • Improve system performance through prompt iteration, tooling design, and architectural changes
  • Implement guardrails, fallback logic, and human-in-the-loop flows where appropriate

Collaborate & think in systems

  • Translate vague business problems into concrete technical architectures
  • Work across product, data, and domain constraints - not in isolation
  • Contribute to internal patterns, templates, and reusable ClearCortex IP

Requirements

Do you have experience in TypeScript?, Do you have a Master's degree?, Core skills

  • Strong software engineering fundamentals
  • Proficiency in Python and/or TypeScript
  • Experience building and shipping production software

AI / agent experience

  • Hands-on experience with modern LLM APIs (OpenAI, Anthropic, Gemini, etc.)
  • Experience with agent frameworks (LangChain, LangGraph, LlamaIndex, or custom systems)
  • Practical experience with:
  • RAG and retrieval pipelines
  • Tool use and function calling
  • Multi-step reasoning workflows
  • Prompt engineering beyond single prompts

Systems thinking

  • Comfortable reasoning about:
  • Failure modes
  • Observability and logging
  • Cost vs performance tradeoffs
  • Autonomy vs control
  • Ability to debug agent behaviour systematically (not by guesswork)

Nice-to-Have (Not Required)

  • Experience with vector databases (Qdrant, Pinecone, Weaviate, etc.)
  • Familiarity with evaluation techniques for LLMs and agents
  • Experience deploying AI systems in cloud environments (Docker, CI/CD, basic DevOps)
  • Prior work in applied ML, NLP, or decision systems
  • Startup, studio, or early-stage product experience

Benefits & conditions

You'll Thrive Here If You

  • Prefer shipping systems over polishing slides
  • Enjoy ambiguity and figuring things out from first principles
  • Think in architectures, not just prompts
  • Care about real-world impact more than benchmarks
  • Want meaningful ownership, not ticket-driven work
  • Are curious, pragmatic, and opinionated (but evidence-driven)

Why ClearCortex

  • High ownership: You'll help shape how systems are built, not just execute tasks
  • Real problems: Production systems with real users and real constraints
  • AI-native environment: Agents, workflows, evaluation, and tooling are core - not bolt-ons
  • Small, sharp team: Work directly with the founder, move fast, iterate constantly
  • Long-term thinking: Reusable IP, platforms, and products - not throwaway projects

About the company

ClearCortex is an AI studio building production-grade AI systems for real businesses - not demos, not slideware. We design and deploy agentic systems, retrieval pipelines, and AI-powered workflows that operate in messy, real-world environments: incomplete data, unclear requirements, evolving goals, and human decision-makers in the loop. Our work sits at the intersection of: * AI agents & LLM systems * Applied software engineering * Real operational workflows (property, logistics, professional services, internal tooling) We're building reusable IP, internal platforms, and long-term products - while shipping high-impact client systems along the way. If you enjoy turning ambiguity into working systems, this role is for you.
