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).

How to join the mission?

-

Initial Screening Call (45m): First exchange with Olivier Lachenaud (Talent Acquisition Business Partner) to explore your background, career aspirations, and answer any initial questions.

-

Manager Interview (60m): Deep dive into your technical background, domain experience, and alignment with Anaïs Ghelfi (Hiring Manager & Engineering Director).

-

Technical Business Case & Debrief (2h): Practical architecture exercise and debrief with Staff Engineers to evaluate your systems design and agentic architecture mastery.

-

Executive & Culture Fit Interview (2h): Final conversation with Claire (CTO) to discuss Malt’s long-term vision, followed by an informal coffee chat with Raphaël Ouazana & Pierre Reynaud .
