Role mission (descriptive)

As an ML Engineer, you will lead the design, training, and productionization of
Document & Data Intelligence
solutions and enable
agentic AI
capabilities through an internal
AI SDK
that unifies model access, tool-calling, evaluation, and telemetry. You'll work on high-impact use cases, structured extraction from
invoices/DDT/SAL
and field images,
bankdocument reconciliation
,
anomaly detection
on costs/margins, and
cash-flow/cost forecasting,
embedding models and agents into
Accounting, Finance, and Field Ops
workflows with strong security, GDPR-compliant data handling, and
MLOps/LLMOps
best practices (versioning, observability, feedback loops).

What you'll do — example activities (non-exhaustive)

  • Design and maintain the
    AI SDK
    (Python): unified APIs, provider adapters, tool registry, JSON-schema/Pydantic validators, prompt/model versioning, evaluation harnesses, tracing/metrics, retry/backoff, and latency/cost budgets.
  • Build end-to-end pipelines across
    OCR/NLP/LLM
    , tabular ML, and
    time series
    , with clear metrics and production guardrails.
  • Develop
    stateful agents
    (planning, tool-use, memory, reflection) with guardrails and HITL; automate report/timesheet updates.
  • Partner with Product/Backend/Frontend to embed models/agents into workflows (incl. banking integrations and Italian fiscal systems such as
    SDI
    ).
  • Run
    AgentOps/MLOps
    : CI/CD for models & prompts, dataset/versioning, observability (traces/logs/tokens), review queues.
  • Uphold
    privacy, security & compliance
    : PII handling, RBAC/RLS, audit logs, data retention.

Minimum qualifications

  • 3+ years (5+ for Senior) in applied ML with
    production
    delivery of OCR/NLP or tabular models.
  • Strong data engineering (feature engineering, dataset curation, evaluation).
  • Familiarity with
    time series
    and
    anomaly detection
    .
  • Proven experience building
    developer SDKs/libraries
    (API design, packaging, versioning, docs, testing, CI).
  • Preferred experience with
    TypeScript
    (for SDK/frontend)
  • Professional Italian and English.
  • No visa sponsorship:
    EU work authorization required and must already be living in the Milan area.

Nice to have

  • Agentic AI
    (LangGraph/LangChain or equivalents), tool abstraction, memory stores (vector DB/Redis), structured outputs.
  • Hugging Face
    ecosystem (Transformers/Datasets/Evaluate, Hub/model cards, LoRA/PEFT, TRL); optional self-hosting (vLLM/Triton/TensorRT-LLM).
  • RAG
    over fiscal/ERP documents; hybrid search and metadata filters.
  • Domain knowledge:
    Italian invoices, DDT, SAL, bills of quantities
    , banking/fiscal flows (SDI).
