Discover our galaxy

Join the Future of Work ! Malt is Europe's leading freelance marketplace, connecting over 1,000,000 talented freelancers with 100,000+ companies. Founded in 2013, we're transforming how work gets done through our tech‑powered, human‑centered platform. What makes us different:

- A diverse team of 600 Malters across 6 European countries

- A culture that champions equality (50% of our Comex are women) and inclusive growth

- Backed by top investors including ISAI, Serena Capital, Eurazeo Growth, Goldman Sachs, and BPI

- A mission to give everyone the freedom to work differently

- Ready to help shape the future of work? Your next chapter starts here!

At Malt we believe that Ambition is the Way, so all lists of missions and responsibilities are non-exhaustive.

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).
