Strong emphasis on cloud-native architecture, asynchronous processing, and engineering best practices. 🗂️ Requirements: Minimum 8 years of commercial software engineering experience, Proven experience as Architect or Tech Lead in complex distributed systems, Expert-level Python knowledge, Expert-level FastAPI knowledge, Practical experience with asynchronous programming, Hands-on experience with Google Cloud Platform, Experience designing and scaling high-performance APIs, Production experience with LLM integration and AI systems, Experience working with large datasets, Ability to design end-to-end system architecture 📃 Skills: Python, FastAPI, GCP, LLM, LangChain, LlamaIndex, Neo4j, Pinecone, Qdrant, Weaviate, Kafka, RabbitMQ, PubSub, Docker, Kubernetes 🏢 Description: Principal Software Architect / Tech Lead (Python · FastAPI · GCP) Firma: ARX Consilium / OC-ARX Tryb pracy: 100% zdalnie (PL/EU) Forma współpracy: B2B / kontrakt długofalowy Wynagrodzenie: 30 000–40 000 PLN netto + opcjonalny pakiet udziałów (equity) O projekcie Budujemy platformę klasy AI-driven decision platform do zaawansowanej analizy danych prawnych i wspierania procesów decyzyjnych. To nie kolejny prosty SaaS ani generyczne MVP — system działa już produkcyjnie. Rosnąca złożoność (podejścia grafowe, orkiestracja LLM, analityka real-time) wymaga jednak wejścia na wyższy poziom architektoniczny. Szukamy lidera technicznego, który przejmie ster nad stroną technologiczną aplikacji, uporządkuje istniejące rozwiązania i przygotuje platformę pod globalne skalowanie. Zakres odpowiedzialności Projektowanie i rozwój architektury systemu end-to-end, ze szczególnym naciskiem na wydajność, asynchroniczność i bezpieczeństwo. Rola hands-on architect / tech lead — podejmowanie kluczowych decyzji technologicznych, projektowanie API oraz samodzielne wdrażanie krytycznych elementów systemu (proof of concept, core refactor). Refaktoryzacja i skalowanie istniejącego backendu pod kątem modularności, pracy wielu użytkowników jednocześnie oraz stabilnych środowisk test/prod. Orkiestracja warstwy AI — praca z mechanizmami LLM, systemami agentowymi i bazami wektorowymi, z dbałością o niskie opóźnienia, streaming danych i optymalne zarządzanie kontekstem. Wdrażanie najwyższych standardów inżynierskich: automatyzacja release’ów, CI/CD, testy (jednostkowe, integracyjne, obciążeniowe) oraz kultura code review. Wymagania (must-have) Minimum 8 lat komercyjnego doświadczenia w inżynierii oprogramowania, w tym udokumentowana rola architekta lub tech leada w złożonych systemach rozproszonych. Ekspercka znajomość Pythona oraz frameworka FastAPI (programowanie asynchroniczne, optymalizacja zapytań, budowa wysokowydajnych API). Głębokie, praktyczne doświadczenie z Google Cloud Platform (GCP) — warunek konieczny. Rozumienie specyfiki systemów AI-driven: produkcyjne wdrażanie LLM, integracja z modelami AI, praca na dużych zbiorach danych. Myślenie analityczne, umiejętność mapowania złożonych procesów biznesowych na architekturę techniczną oraz jasnego uzasadniania decyzji. Mile widziane Bazy grafowe (np. Neo4j) i systemy reprezentacji wiedzy (Knowledge Graphs) Bazy wektorowe (Vector DBs — np. Pinecone, Qdrant, Weaviate) Narzędzia do orkiestracji AI/LLM (np. LangChain, LlamaIndex) Architektura event-driven oraz systemy kolejkowe (Kafka, RabbitMQ, Pub/Sub) Konteneryzacja i orkiestracja (Docker, Kubernetes) Doświadczenie w domenach o wysokiej odpowiedzialności biznesowo-prawnej ( FinTech, LegalTech, MedTech ) wymagających audytowalności decyzji Kogo NIE szukamy Architektów „gabinetowych” — szukamy lidera, który nie boi się ubrudzić rąk kodem i potrafi sam zrobić core’owy refaktor, a nie tylko rysować diagramy w Miro. „Seniorów” skupionych wyłącznie na przepychaniu tasków z Jiry. Osób bez silnego, praktycznego doświadczenia z chmurą publiczną (GCP) i systemami produkcyjnymi o dużym natężeniu ruchu. Co oferujemy Realny, decydujący wpływ na architekturę i kierunek rozwoju zaawansowanej platformy. Brak korporacyjnego betonu, płaska struktura i szybkie procesy decyzyjne. Wyzwania techniczne, przy których się nie znudzisz (grafy, AI, asynchroniczność, wysoka skala). Długofalową, stabilną współpracę opartą na partnerstwie i zaufaniu. Proces rekrutacji Krótka kawa online (15–20 min) — poznajmy się i sprawdźmy, czy nadajemy na tych samych falach. Rozmowa techniczna (system design, FastAPI, GCP, architektura) — konkretna dyskusja inżynier z inżynierem, bez algorytmów rodem z kosmosu. Decyzja i oferta.
