We're looking for an

AI/ML Engineer

to join a global leader in HR technology — a team

building Generative AI assistants

used across general markets.
This is a

hands-on engineering role

, where focus is

shipping GenAI/NLP models to production

in

Python

, working shoulder-to-shoulder with MLEs inside a lean 5–6 person squad across 3–4 projects. If you code your ML solutions yourself rather than leaning on out-of-the-box AutoML tools, and you like owning the technical solution end-to-end, this is for you.
What you'll find here:

Building

production-ready GenAI/LLM features

— chatbot assistants and NLP systems, from prototype to production.
Writing

structured, quality Python

with real engineering discipline:

PR practices, Git, CI/CD, Docker

.
Designing

end-to-end NLP pipelines





— data processing, model development, evaluation, deployment.
Getting hands-on with

LLMs, embeddings and modern GenAI tooling

(OpenAI, AWS Bedrock).
We're looking for someone who:

Brings

3–5 years

of experience building

production features/systems with AI/ML

.
Writes

advanced, production-grade Python

— not notebook scripting.
Has worked on

real NLP / GenAI / LLM projects

and can explain them in depth — embeddings, evaluation metrics beyond accuracy, how they assessed system performance.
Thinks like an

ML engineer

: moves models to production, understands the full pipeline, applies solid coding practices (

Git, PR, CI/CD, Docker

).
Knows their way around

ML libraries

(scikit-learn, PyTorch) and

data processing

(pandas).
Nice to have:

Experience with

Databricks.
Familiarity with

AWS infrastructure

(S3, Lambda, Bedrock).
Understanding of

data augmentation, bias and training pi
