The Product Analyst is a core member of the Product Design team, responsible for translating business needs, and system requirements into clearly defined design and technical execution documentation. This role is responsible for defining the logic, behavior, and detailed UI functionality of the app. Depending on the feature complexity, the Analyst either takes the lead in clarifying requirements from scratch or ensures the user interface aligns perfectly with backend technical specifications provided by System Analysts.

The purpose of the Product Analyst is to translate business needs into comprehensive, unambiguous UI Design Documents (UIDD). For complex features, this means honoring the "back-end reality" defined by System Analysts; for simpler features, it means taking full ownership of requirement gathering and logic definition. Success is defined by the elimination of logic gaps, the technical accuracy of UI specs, and a seamless knowledge transfer that ensures features are buildable and testable.

Job Duties and Responsibilities

• Adaptive Requirement Ownership: Lead the gathering and clarification of product and UI requirements with stakeholders. For complex features, interpret technical documentation (APIs, flows) from System Analysts to ensure UI designs are both user-centric and technically feasible.
• UI Functional Documentation: Create and maintain the "Source of Truth" (UI Design Documents) that describes the interface logic—defining button behaviors, state changes, and branching logic.
• Data-to-UI Mapping: For features with backend integrations, document how data points from API responses map to specific UI elements, including handling different data types and validation states.
• Edge Case Identification: Proactively identify and document missing states (loading, empty, error, or success) and "what-if" scenarios that visual designs or technical flows may not explicitly detail.
• Label & Message Standardization: Maintain high UI standards by ensuring total consistency and clarity of software UI elements, including system messages and error notifications that align with both the user experience and technical requirements.
• Collaborative Logic Mapping: Partner with Product Designers to ensure the intended user flow is intuitive and with System Analysts (when involved) to ensure the UI supports the required technical sequence.
• Design QA & Functional Verification: Act as a functional QA to verify that final builds and UI samples align perfectly with both the documented UI logic and the original requirements/specifications.
• Knowledge Transfer: Provide clarifications and walkthroughs of documented designs to management, engineering, and QA teams to minimize development friction and community cycles.

Requirements & Qualifications

• Experience & Education: 3-6 years of experience in Product Analysis, Business Analysis, or Technical Writing in a software environment. A Bachelor’s degree in Computer Systems, Business, or a related field is preferred.
• Technical Interpretation: Proven ability to read and interpret complex technical documentation, including API specifications, JSON structures, and system architecture flows provided by System Analysts.
• Systems Thinking: The ability to analyze how a UI change impacts the broader application ecosystem and corresponds to existing backend data structures and dependencies.
• Precision Technical Writing: Mastery in writing concise, "developer-ready" functional specifications that eliminate ambiguity and reduce follow-up questions from Engineering and QA.
• Logic & Specification Skills: Exceptional ability to deconstruct complex user journeys into granular, "if-then-else" functional behaviors.
• Stakeholder Management: Strong communication skills with the ability to lead requirement-gathering sessions with both non-technical business stakeholders and technical teams.
• Tool Proficiency: Experience with documentation and collaboration tools (e.g., Confluence, Jira) and familiarity with design tools (e.g., Figma) for reviewing and annotating UI components.

Analytical Mindset: A "detective" approach to software—naturally inclined to uncover edge cases, potential errors, and inconsistencies in user flows.

Data Science UA is a service company with strong data science and AI expertise. Our journey began in 2016 with uniting top AI talents and organizing the first Data Science tech conference in Kyiv. 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.
