Senior Fullstack Engineer (Flutter/Node.js) - Mobile Experience

As a Senior Flutter Engineer you will strengthen the delivery capacity of the Mobile Experience crew within Kpler’s Application Platform tribe. The role centers on delivering high-performance, critical features for the MarineTraffic and Kpler mobile applications—serving millions of users—using Flutter and Dart. This large-scale environment requires a sharp focus on performance across the entire stack while upholding Clean Architecture standards.

​You will join a pioneering squad at the forefront of AI-assisted engineering, where 100% of the code deployed is authored by AI under your orchestration. This is a highly modern environment designed for engineers who want to redefine software delivery by leveraging advanced AI tools to achieve unparalleled quality and velocity.

​Working within a close-knit multidisciplinary squad (1 EM, 1 Tech Lead, 1 Mid-level Engineer, 1 PM, 1 Designer), you will lead mobile feature development and may also contribute to the evolution of our Node.js/TypeScript Backend-for-Frontend (BFF) as a secondary component to support the mobile experience. They will also help business teams become autonomous over their own functional scopes, acting as a key enabler of the crew’s platformisation strategy.

Develop complex, production-ready features for the MarineTraffic and Kpler mobile apps, upholding and protecting the team’s Clean Architecture standards.

Participate in code reviews as a quality guardian, providing constructive feedback that elevates team standards.

Collaboratively design and evolve the mobile Backend-for-Frontend (BFF) using Node.js, TypeScript and GraphQL, ensuring the crew’s agility and reducing external dependencies.

Adopt and continuously improve engineering practices: CI/CD pipelines, GitOps, linters, Sonar, and peer review workflows.

Maintain and improve automated test suites (Unit, Integration, Contract) to uphold software quality.

Mentor peers within the squad and contribute to the Front-end Chapter to harmonise practices between Web and Mobile teams.

Support business teams in becoming autonomous over their functional scopes within the mobile apps, as part of the crew’s platformisation strategy.

Contribute to architectural discussions and incremental improvement initiatives with pragmatism and a collaborative mindset.

Maintain and optimize the LLM and AI integration stack (e.g., Cursor, Claude Code) to ensure the configuration and evolution of tools enabling agents to write code autonomously with a high degree of quality, adhering to all team standards (rules, commands, and architecture).
