Middle Full-Stack Developer

About the Position

Data Science UA is a service company with deep expertise in AI and Data Science, built one of the largest AI communities in Europe. We're looking for a Full-Stack Developer to join our team and help build an end-to-end pipeline for machine learning.

Responsibilities12

• Work alongside a senior developer to build a pipeline that ingests camera streams, passes frames through ML inference, and surfaces results in a web UI.
• Write clean, maintainable, and efficient code following SOLID/DRY and team standards.
• Build real-time UIs that visualize streaming data — live video, detections, charts, overlays, and dashboards.
• Implement backend services in Python to handle stream ingestion, orchestrate ML calls, and expose APIs to the frontend.
• Integrate with external services and APIs with proper auth, retries, timeouts, and error handling.
• Design and maintain database schemas, indexes, and migrations; optimize queries where it matters.
• Diagnose, reproduce, and fix bugs across the stack.
• Create and maintain documentation.
• Participate in code reviews and architectural discussions; propose improvements.
• Join team ceremonies and planning.
• Ensure data security and help mitigate vulnerabilities.
• Optimize server and application performance, especially around streaming and real-time data paths.

Requirements11

• Solid proficiency in JavaScript/TypeScript for frontend development.
• Working knowledge of Python for backend services and pipeline glue code.
• Experience building UIs with modern frontend libraries (React and component kits such as AntD, MUI, or similar).
• Understanding of REST API principles and how to design clean HTTP interfaces.
• Experience working with WebSockets (or similar) for real-time data delivery to the UI.
• Familiarity with video/camera streaming protocols — RTSP, WebRTC, or HLS — and the basics of how frames move from a camera to a backend.
• Experience with relational and/or non-relational databases.
• Experience integrating with third-party systems and APIs.
• Understanding of Git beyond basic commits (branching, rebasing, resolving conflicts, working in feature branches).
• Basic knowledge of web security (auth, input validation, common vulnerabilities).
• Experience with AWS (S3, Lambda, SQS, CloudWatch) or equivalent services from other cloud providers.

Benefits5

• Work in a fast-paced, dynamic, and innovative business environment.
• Opportunity to directly influence the company's strategic IT architecture and products that scale globally.
• Access to modern tools, technologies, and in-house expertise.
• Flexible approach to project delivery and freedom to choose optimal technical solutions.
• Performance-based bonus system tied to team results.
