Staff Engineer Platform
Malt · Paris, France +1 · 1mo ago
Explore your future career
You will join the Platform team, the foundational engine driving the Malt marketplace across our backend (Kotlin/Java), frontend (Nuxt/VueJS), and GCP cloud infrastructure.
Your mission is to define and drive the long-term technical vision for that platform: the shared foundations, tooling, and internal infrastructure that every engineering squad builds on, and the agentic workflows that will change how we ship software.
Both matter equally - a strong agentic layer only compounds on solid platform foundations, and our foundations only stay relevant if they make autonomous workflows a first-class citizen.
Either way, the goal is the same: multiply the output of everyone who touches our product, reliably and securely, at Malt scale.
Key responsibilities
-
Set the Long-Term Platform Tech Strategy: Define the 2–3 year technical vision and roadmap for Malt's engineering platform — backend, frontend — alongside platform leads, ensuring architectural consistency, security, and high reliability across all engineering squads. Agentic capabilities are a central pillar of that vision, not a side project.
-
Architect Platform Foundations: Partner closely with Backend, Frontend, and SRE leads to design and build our company-wide platform foundations — from core shared infrastructure through to our agentic layer, consolidating existing POCs into unified, enterprise-grade capabilities.
-
Pioneer Agentic DevEx Workflows: Prototype, scale, and embed autonomous AI agents into the software development lifecycle (e.g., agentic MR reviews, automated code quality, and security fixes) so product teams can focus strictly on core product logic.
-
Deliver Platform-as-a-Product: Provide product engineers with self-service tools, reusable components, clear guardrails, and documentation making both our platform foundations and our autonomous workflows the natural, default way to ship software at Malt.
-
Build, Hands-On: Contribute directly to the platform. You'll write production code on the systems you design: the hardest parts, the reference implementations, the things nobody else can unblock.
-
Raise the Bar: Drive the adoption of best practices, coding standards, and high-quality engineering processes, including thorough code and architecture reviews. Foster operational excellence across the platform.
-
Mentor and Coach: Provide technical guidance and mentorship to engineers across the platform team, particularly Senior and mid-level engineers, helping them develop their skills, master agentic patterns, and advance their careers.
-
Drive Technical Alignment & Change Management: Act as a technical catalyst, influencing and aligning backend, frontend, and engineering leads around transformative AI agent paradigms without relying on top-down authority.
About you
-
Technical Expertise: You have 15+ years of professional experience in software engineering, including a proven track record operating at a Staff or Principal level in high-scale platform environments. You're highly proficient in Kotlin or Java, comfortable across GCP and modern web frameworks (e.g. Nuxt/VueJS), and at ease navigating complex backend architecture, APIs, and data models.
-
AI-Driven Innovator: Passionate about AI topics, you regularly keep up to date with the latest developments. You have already built product-grade agentic workflows within the software development lifecycle: systems engineers rely on daily to review, test, or ship code, not demos or POCs.
-
Clear leadership: You excel at working effectively in uncertain and evolving environments, managing the interaction between technical objectives and business priorities.
-
Platform as a Product Mindset: You think beyond the code. Your product is the developer experience: you're curious about the "why" behind the workflows, core components you build, proactive in proposing improvements, and you own delivery from A to Z: including the adoption, not just the architecture.
-
Resourceful: You always find a way of getting things done, even under severe staffing constraints.
-
Impactful: You demonstrate excellent ownership and problem-solving skills, with a high degree of agency in driving solutions.
-
Strong interpersonal abilities: You possess excellent written and oral communication skills in English (French is a valuable bonus).
