    We’re looking for an Applied AI Engineer who combines strong ML fundamentals with the discipline of improving production AI systems through metrics, evaluation, and iteration.

    Details:
    Senior AI/ML Engineer, ideally 5 years of experience. Ready to consider candidates starting with 3 years of experience, but they must be very strong in AI/ML.
    Strong proficiency in English (Upper-intermediate level or Advanced)
    Full-time
    Location: any
    Start: ASAP!

    The role in a nutshell
    You’ll work on improving production AI systems through evaluation, experimentation, and system design.

    A large part of the role involves:

    diagnosing failures in agent workflows
    designing evaluation metrics and KPIs
    improving system prompts and agent behavior
    running structured experiments and measuring impact
    You won’t be working in isolation on research projects — you’ll be improving systems that real users depend on.

    Rough responsibility breakdown:

    AI evaluation and KPI design — ~30%
    Prompt and agent system design — ~30%
    ML systems (recommendation, optimization, etc.) — ~30%
    Engineering integration — ~10%

    What you’ll work on:

    AI evaluation and system quality

    Design evaluation strategies for LLM and agent workflows
    Create metrics and KPIs for AI system performance
    Build and maintain evaluation datasets
    Debug production AI failures systematically
    Compare system behavior against baselines
    This is a core responsibility of the role.

    Multi-agent AI systems

    Improve agent orchestration and workflows
    Diagnose failures across agent pipelines
    Refine system prompts and agent interactions
    Improve reliability, latency, and response quality of ML and AI systems

    You’ll contribute to areas such as:

    Recommendation systems (ranking and personalization)
    Itinerary optimization and constraint-based planning
    LLM-based reasoning systems
    Optional: computer vision pipelines
    Depth in one of these areas is more important than superficial experience in all of them.

    Engineering collaboration
    We use:

    Golang (primary production language)
    Python when necessary for ML workflows
    Postgres, Redis, and internal services
    You don’t need to be a Go expert on day one, but you should be comfortable reading and modifying production code.
    Backend engineers handle infrastructure-heavy service development — your focus is on AI system behavior and correctness.

    What we’re looking for
    Must-haves
    1. Strong AI/ML fundamentals
    You understand the theory behind what you build and can choose appropriate methods for a problem.
    Examples:
