Over the past 9 years, we have diligently fostered one of the largest Data Science & AI communities in Europe.

    About the role:
    We are looking for a Python Software Engineer to join our team and help us build an on-premise software pipeline for real-time computer vision. The system ingests camera streams (primarily RTSP), stores frames in a shared data layer, runs CV/AI engines for preprocessing and inference, applies inference logic to produce decisions, and sends results to Database/Portal/Alerting/Control integrations.

    Responsibilities:
    - Build and maintain the Camera Module to reliably ingest RTSP streams, decode frames, and handle reconnect/keep-alive/packet loss.
    - Implement the Shared Data layer for raw and processed frame exchange across processes with backpressure and safe lifecycle management.
    - Integrate and operate CV/AI Engines in Python (preprocess, inference, postprocess) with configurable model loading and runtime selection.
    - Develop the Inference Logic layer that orchestrates cropping, batching, filtering, classification, and decision output formatting.
    - Implement connectors for Database & Portal (event persistence, evidence references) and for Alerting & Control (events/hooks for downstream automation).
    - Ensure production readiness on Linux with observability (logs/metrics), health checks, and robust error handling.

    Requirements:
    Must-have:
    - Strong Python, OOP, clean architecture, typing preferred.
    - Solid experience with multiprocessing/concurrency (process lifecycle, IPC patterns, queues/shared memory).
    - Comfortable working in Linux (systemd/service mindset, networking basics, profiling/debugging).
    - Familiarity with CV/AI tooling, and some related Python libraries such as numpy, opencv (cv2), and torch or tensorflow.
    - Ability to work with streaming data and reliability constraints (timeouts, retries, resource cleanup).
    Should-have:
    - Experience with RTSP/RTP streaming and common issues (UDP vs TCP interleaved, jitter, packet loss, camera timeouts).
    - Performance optimization (profiling, memory management, zero-copy patterns).
    - Exposure to inference acceleration stacks (TensorRT/OpenVINO) or GPU deployment.
    - Experience designing event schemas and integration with DB/message queues.

    We offer:
    - Free English classes with a native speaker and external courses compensation;
    - PE support by professional accountants;
    - Medical insurance;
    - Team-building events, conferences, meetups, and other activities;
    - There are many other benefits you’ll find out at the interview.
