Staff Data Platform Architect

GitGuardian; Paris; Hybrid; EUR 120,000 - 170,000; Full time

Job summary

GitGuardian is seeking a Staff engineer for the Public Intelligence squad to own the end-to-end architecture of the public data platform. You’ll write production code on critical paths, while shaping a technical strategy with the Engineering Manager and Product Manager.

You’ll lead design workshops, align multiple squads, and mentor engineers to raise the team’s technical bar. This role emphasizes real-time processing, data lakes, and AI-assisted development.

Qualifications

• 7+ years building and operating large-scale, data-intensive systems in production, as a data engineer or a backend engineer.
• Strong software engineering: designed and run high-throughput collection or ingestion services, with queues, back-pressure, retries and idempotency.
• Production experience with real-time, event-driven processing and the latency targets that come with it.
• Strong data architecture: data lakes on object storage, analytical databases at scale (ClickHouse or similar), and data modeling for pipelines.
• Python expert.
• Proven experience redesigning a production architecture step by step, migrating without downtime or data loss.
• An operations mindset: you design observability and alerting together with the system, and you know how to run an incident.
• Technical leadership: you align several engineers on a target architecture, mentor them, and explain your decisions in writing.
• Deliberate use of AI coding agents: you give them context and a spec, read what they produce, and catch what they get wrong.
• Fluent English in an international environment.

Responsibilities

• Own the end-to-end architecture of the public data platform: collection, real-time processing, storage, and delivery to our agents and product.
• Stay hands-on: write production code on the most critical parts, starting with the collectors, the real-time processing and the migrations.
• Turn the squad’s priorities into a technical strategy and roadmap, together with the Engineering Manager and the Product Manager.
• Lead design workshops, and make decisions the squad can build on.
• Drive the architecture decisions that span several squads, and get them aligned.
• Mentor the squad’s engineers and raise the technical bar through design reviews and knowledge sharing.
• Lead the squad’s software factory. AI agents write a growing share of our code, and you will define how we build with them.
