Résumé du poste

Deezer in Paris seeks a Senior Expert Platform Engineer to shape our Internal Developer Platform (IDP). You will drive platform strategy, architecture, and execution to help engineers ship faster, safer, and with higher quality.

You will collect needs from engineering teams, set standards with senior engineers, mentor peers, and bridge platform engineering with AI and cybersecurity. This role calls for leadership across DevXP functions and a focus on reliability and security.

Qualifications

• Degree in Computer Science or equivalent.
• 8+ years in platform engineering or DevOps, with 3+ years at senior/expert level.
• Track record of operating platforms at scale; fluency with TDD, trunk-based development, and continuous delivery.

Responsabilités

• Platform Engineering - Architect and evolve the IDP, CI/CD pipelines, and automation frameworks. Own the long-term technical vision, define platform standards (IaC, GitOps), and select best-in-class tooling across build, deployment, monitoring, and security.
• Developer Experience - Proactively identify and eliminate friction across the software lifecycle. Track DX metrics (DORA, SPACE) and use data to prioritize platform investments. Be the internal advocate for developers.
• AI-Augmented Platform - Integrate AI capabilities into the platform (intelligent code review, anomaly detection, smart test generation). Evaluate and operationalize AI tools (GitHub Copilot, LLM-based assistants) and explore agentic automation to reduce developer toil.
• Security & Compliance - Embed security-by-design into every platform layer: secure CI/CD (SAST, DAST, SCA, secret scanning), supply chain integrity (SLSA, SBOM), and least-privilege access. Lead our journey toward a DevSecOps culture, building the practices, automation, and mindset that will make security a first-class citizen across all engineering teams - an ambition we are actively working toward.
• Reliability & Observability - Define SLOs/SLAs for platform services, ensure full-stack observability, lead incident response, and conduct blameless post-mortems.
• Cross-functional Leadership - Collaborate with Engineering, SRE, Infrastructure, and Security teams. Mentor engineers, represent DevXP in architectural forums, and communicate technical trade-offs to diverse audiences.
