Job Description
Description
We are looking for someone who feels equally comfortable writing code and talking to customers, seamlessly bridging technical and business perspectives.
Work directly with business users to understand workflows, constraints, and improvement opportunities; define measurable hypotheses and KPIs (precision/recall, false-positive reduction, turnaround time).
Design and build Django REST APIs and admin workflows triggering asynchronous Celery tasks (Redis-backed queues).
Develop and maintain AI/LLM pipelines (RAG, classification, ranking, deduplication) with strong focus on evaluation, monitoring, guardrails, and explainability.
Rapid prototyping (notebooks, microservices, APIs) and validating solutions on real datasets.
Build and ship modern web applications using React 18, Next.js, and Tailwind (component-driven architecture, secure API integrations).
Own PostgreSQL schemas, migrations, and performance tuning for data-heavy workloads.
Present outcomes to business stakeholders, recommend rollout strategies, and drive AI best practices internally.
Requirements

Solid front-end experience with React 18, Next.js, and Tailwind CSS.
Strong SQL/PostgreSQL skills (data modeling, migrations, performance optimization).
Practical Docker experience in dev/staging environments.
Proven AI/ML delivery track record with measurable business impact; fluent English and Polish with strong stakeholder communication skills.
