Kpler is a global intelligence platform helping clients navigate complex markets in commodities, energy, and maritime sectors. Founded in 2014, the company has grown to over 850 experts across 69 countries, transforming intricate trade data into actionable strategies.
As a Senior Fullstack Engineer on the Web Experience team, you will drive the technical evolution of Kpler's flagship applications—MarineTraffic and Kpler Terminal—which serve millions of global users. You will work alongside product managers and designers in a senior engineering crew, taking ownership of platform-level initiatives that impact approximately 20 feature teams.
Key responsibilities include:
• Unifying multi-platform user experience by migrating flagship applications onto Atlas, Kpler's component library and shared Tailwind-based design system built in Vue 3 and React.
• Building platform-level microservices, including Backend-for-Frontend (BFF) layers and microservices powering maps, search, user dashboards, and preferences across web and mobile platforms.
• Elevating developer experience by modernizing monorepo tooling, CI automation, migration pathways, and frontend architectural conventions for ~20 feature teams.
• Pioneering AI-first engineering by integrating advanced AI development tools like Cursor and Claude Code across the engineering lifecycle to optimize workflows and boost technical velocity.
• Championing architectural excellence by architecting resilient, decoupled systems leveraging hexagonal architecture, Domain-Driven Design (DDD), event-driven patterns, and micro-frontends.
• Mentoring and elevating engineering craft through technical documentation, code reviews, frontend chapter presentations, and biweekly developer sessions.
Your technical leadership and engineering standards will directly shape how millions of users interact with real-time trade, energy, and maritime intelligence.
REQUIREMENTS (Must-haves):
• Senior fullstack engineering experience: Proven track record of architecting, building, and operating production web applications and microservices at scale.
• Core technical stack proficiency: Mastery of TypeScript across the stack, modern frontend frameworks (Vue 3, React), and backend services using Node.js.
• Platform & API architecture: Deep experience with REST/GraphQL APIs, microservices, Backend-for-Frontend (BFF) patterns, and data persistence (PostgreSQL, Elasticsearch, Kafka).
• Pragmatic delivery & platform mindset: Eagerness to balance high architectural quality with rapid, iterative product delivery that enables both end-users and developer teams.
• AI-assisted engineering approach: Active hands-on experience utilizing AI development tools (e.g., Cursor, Claude Code) to accelerate daily engineering workflows.
Nice-to-haves:
• Specialized web technologies: Experience with Mapbox, GraphQL schema federation, Python, or Scala.
• Advanced architecture & tooling: Practical experience with monorepos, micro-frontends, hexagonal architecture, or Domain-Driven Design (DDD).
• Design system maintenance: Experience maintaining or contributing to shared component libraries and design systems utilized across multiple teams.
