Senior Full Stack Engineer

MR MARVIS is a fast-growing Amsterdam-based menswear brand. We are looking for a Senior Full Stack Engineer to join the PEDX team to build and improve our digital commerce platform using modern technologies like Next.js, React, TypeScript, and GCP.

• Build and improve modern full-stack applications using technologies such as Next.js, React, TypeScript, backend services, Sanity, Algolia, and Shopify.
• Take ownership of architectural decisions and technical delivery across key parts of our commerce platform.
• Help design and build our in-house integration platform, replacing dependency-heavy external workflows with reliable, observable, and maintainable systems.
• Improve the resilience of business-critical flows such as product data, orders, inventory, returns, and fulfilment integrations.
• Introduce and maintain strong engineering practices around code quality, testing, observability, documentation, and incident prevention.
• Mentor medior and junior engineers through pairing, review, coaching, and thoughtful technical guidance.
• Collaborate with product owners and stakeholders to balance speed, quality, scalability, and business impact.
• Contribute to technical roadmaps, architecture decision records, and long-term platform direction.

• Significant experience as a full stack engineer, preferably in a senior or lead capacity.
• Strong experience with TypeScript, React, Next.js, and modern web application architecture.
• Solid backend engineering experience, including GCP Docker, Serverless, K8S, APIs, services, data flows, and integration patterns.
• Experience working with commerce, content, search, ERP, fulfilment, or other operational systems is a strong plus.
• A pragmatic engineering mindset: you know when to move fast, when to simplify, and when to invest in foundations.
• Comfortable owning complex technical domains independently while collaborating closely with others.
• Strong communication skills and the ability to explain technical trade-offs clearly to non-technical stakeholders.
• A coaching mindset and the ability to raise the quality and confidence of the wider engineering team.
• Curiosity, accountability, and a strong product sense.
