Senior Technical Product Owner – Security Platform

Location: Paris area, France
Work Model: Hybrid
Contract Type: CDI or B2B
Languages Required: Fluent French and English

About the Company

We build smart, resilient, modern software that transforms how enterprise organizations operate. We combine strategic consulting, rigorous product thinking, and world-class engineering with AI-assisted delivery workflows. We take complete ownership of the solutions we build, challenge requirements directly, and focus relentlessly on functional and technical excellence.

The Project & Client: Rebuilding RATP’s Security Operations

We are building a dedicated, autonomous product engineering squad directly responsible for redesigning and rebuilding the central, mission-critical security control centre platform for RATP, the backbone of Paris’s public transportation network.

The legacy platform, which has operated around the clock for decades, is being replaced from scratch with a high-performance, resilient web application. This system operates 24/7, processing real-time alarms and telemetry from field equipment, CCTV cameras, automated vehicle location systems, radio transmissions, telephony, and multi-agency partner networks.

Control-room operators from several organizations collaborate concurrently within the interface to track live incidents on GIS maps, dispatch field intervention teams, and manage emergencies where sub-second latency and absolute fault tolerance are essential.

You will join a specialized team that owns and manages its product and technical delivery, collaborating closely with RATP domain experts while maintaining full delivery ownership.

Working Model & Location Requirements

• Base Location: You must reside in the Île-de-France (Paris region) and hold valid work authorization in France. French citizenship is not required; valid residency and the right to work in France are essential.
• Hybrid Model: This role strongly emphasizes collaborative, in-person teamwork. The newly formed squad will spend the majority of each week working together on-site.
• Work Environment: To foster dedicated teamwork, the squad will operate from an independent collaborative tech hub in Paris, such as Station F or an equivalent premium collaborative space, rather than inside standard legacy client offices.

What You’ll Do

• Own the Core Domain Backlog: Drive functional direction and roadmap execution for critical real-time operational modules, from discovery through technical refinement, testing, and production release.
• Partner with Control-Room Operators: Work directly with operational stakeholders, dispatchers, and domain specialists to understand real-world incident lifecycles, emergency escalation paths, permission matrices, and edge cases.
• Write Unambiguous Technical Specifications: Translate complex real-time workflows into precise user stories, explicit data contracts, state-machine diagrams, and clear acceptance criteria ready for engineering implementation.
• Collaborate Daily with Engineers: Work closely with Java/Spring Boot backend architects, React/TypeScript frontend developers, and QA leads to define API boundaries, data models, and event-driven processing trade-offs.
• Model Real-Time Workflows: Define and validate platform behavior for high-throughput alarm ingestion, interactive GIS mapping, low-latency live video streaming, and multi-tenant organizational permissions.
• Leverage Modern AI Tooling: Actively integrate AI-assisted workflows using Claude, ChatGPT, Cursor, and Gemini to accelerate specification drafting, scenario stress-testing, and ticket refinement while retaining full accountability for functional accuracy.

Candidate Profile

• 8+ Years of Software Product Experience: Proven track record as a Product Owner, Technical Product Owner, or Senior Technical Business Analyst responsible for sophisticated, custom-engineered enterprise software.
• Complex Systems Ownership: Demonstrated experience managing platforms with complex permission structures, asynchronous or event-driven architectures, third-party integrations, or time-critical data flows.
• Technical Literacy: You do not need to write production code, but you must comfortably understand backend/frontend boundaries, REST/WebSocket APIs, JSON structures, relational data models (SQL/PostgreSQL), and event-driven architecture. Hands-on experience using tools such as Postman and browser developer tools to inspect payloads and troubleshoot issues is expected.
• Analytical Precision: Outstanding ability to break down complex, multi-stakeholder operational procedures into clear, structured, and modular functional documentation.
• Languages: Full professional bilingual proficiency in French and English (C1 minimum in both), with the confidence to facilitate discovery workshops and challenge stakeholder assumptions.
• Location & Work Authorization: Based in Île-de-France, with permanent legal authorization to live and work in France, and enthusiasm for frequent on-site teamwork in Paris.

Tech Stack & Tooling

• Core Platform Stack: React, TypeScript, Java, Spring Boot, PostgreSQL, event-driven architecture and message queues, GIS mapping, browser-based video streaming, and secure REST APIs.
• Discovery & Delivery Tools: Jira, Confluence, Notion, Slack, Miro, Excalidraw, Figma, and Postman.
• Productivity & Automation: Claude, ChatGPT, Gemini, n8n, and Make.

Nice to Have

• Previous experience in mission-critical environments, including public transit, emergency services, command and control centres, IoT telemetry, real-time dispatching, or GIS/video streaming platforms.
• Formal certifications such as PSPO, PSM, or AgilePM.
