ppSklum Digital AI is an agentic-native team: a small, high-leverage group that heavily uses agentic AI workflows to build applications and scale our impact far beyond traditional team sizes. For this role in particular, agentic fluency is essential - you will be expected to use agentic tooling every day to multiply your own output, and to help shape how the team leverages these tools. /ppWe are looking for a Principal Fullstack Engineer to be a major hands-on builder of the new Sklum app, which we are building from scratch. This is a mobile-first fullstack role: the primary focus is React Native for mobile, extended with the backend work needed to deliver features end-to-end. /ppThis is a primarily hands-on individual contributor role - you will spend most of your time writing and shipping production code. You will report to the Principal Engineer - Architect and work closely alongside the Principal Software Engineer - Backend Data and other senior engineers to deliver the app from zero to one. /ppThe team operates across multiple cultures, locations, and time zones, and works asynchronously by default. We are looking for an engineer who thrives in distributed environments and builds strong working relationships across geographies. /ph3What you'll be doing /h3h3Mobile-First Fullstack Engineering /h3ulliDesign, build, and ship features end-to-end across the Sklum app - from the React Native mobile experience to the backend services that power it. /liliOwn the mobile experience layer: architecture, navigation, state management, performance, offline behavior, and production-grade patterns in React Native. /liliExtend into the backend when needed: build APIs, services, and data flows that support the mobile experience, in close collaboration with the Backend Data engineer. /liliContribute to the web experience (React / Next.js) where features span platforms, ensuring consistency of behavior and design system across mobile and web. /li /ulh3Quality, Performance, and Craft /h3ulliWrite production-grade, well-tested, observable code; own features end-to-end from design through deployment and on-call. /liliDrive performance, reliability, accessibility, and security of the mobile experience. /liliEstablish and maintain engineering standards for the fullstack work you touch - code quality, testing, CI/CD, observability. /li /ulh3Agentic-Native Ways of Working /h3ulliUse agentic AI workflows as a core part of day-to-day engineering - from design and coding to testing, review, and operations - to scale your own output and the team's capacity. /liliContribute to the team's agentic operating model: identify where agents can take on more work, where guardrails are needed, and how to keep quality and security high. /liliSet a standard for others by showing what one engineer plus well-designed agentic workflows can deliver. /li /ulh3Collaboration Across the Team /h3ulliPartner closely with the Architect, the Backend Data engineer, product, design, and other specialists to deliver end-to-end capabilities. /liliProvide technical mentorship and code review, raising the bar for mobile and fullstack engineering across the team. /liliWork effectively across cultures, locations, and time zones in a distributed, asynchronous-first environment. /li /ulh3Why work with us /h3pThis role sits at the core of SKLUM's Digital and AI team, directly shaping how supply chain decisions are made. You will build a capability that improves forecast accuracy, optimises inventory and distribution, and enhances operational resilience - work that directly influences cost efficiency, product availability, and the end customer experience. /ph3Benefits you canenjoy /h3ulliPrivate health insurance /liliRelocation policy /li /ulh3Join our dream, join the SklumTeam! /h3h3What we'd like to see /h3ulli8+ years of professional software engineering experience, with a strong record of shipping production systems in hands-on roles. /liliDeep, hands-on expertise with React Native - including architecture, performance optimization, native module integration, and production-grade patterns at scale. /liliStrong backend engineering skills - designing and building APIs, services, and data flows that support consumer-facing mobile apps. /liliWorking expertise with React and Next.js for web, and the ability to contribute to the web experience when features span platforms. /liliSolid understanding of mobile delivery practices: app store release processes, over-the-air updates, mobile observability, crash reporting, and A/B testing. /liliProven ability to design and build applications end-to-end from scratch, and to extend or integrate with existing in-house or third-party systems. /liliExperience in e-commerce, marketplace, retail, or other consumer-facing digital platforms. /liliFamiliarity with operational systems that surround a consumer app (ERP, CRM, PIM, CMS) and how they connect to the mobile and backend layer. /liliExperience with cloud-native architectures (AWS and/or GCP), containerization, and modern CI/CD practices. /liliHands-on experience working in an agentic-native way - using agentic AI tools (e.g., coding agents, autonomous workflows) as a core part of building software, and a demonstrated ability to scale personal and team output through them. /liliProven ability to collaborate effectively across different cultures, locations, and time zones in a distributed, asynchronous-first environment. /liliStrong written and verbal communication skills; fluency in English is required. /liliWorking proficiency in Spanish or Chinese is a plus. /li /ulpAt our company, we are firmly committed to guaranteeing equal opportunity for all people in our workplace, building an inclusive and equitable environment. We value each employee for their talents, skills, and contributions, regardless of their race, religion, colour, origin, gender, sexual orientation, age, marital status, or disability. /p /p #J-18808-Ljbffr
