Original job description

English section of this bilingual listing.

Senior Software Developer - FrontEnd

Plusgrade builds the web applications that allow passengers worldwide to purchase upgrades, and we need someone ready to lead the frontend architecture of our next complex transactional products.

What You'll Be Doing

You will take ownership and technically drive the delivery of high-quality web applications using React in an Agile environment. You will lead technical architecture discussions in front of a whiteboard, reduce system complexity, and communicate technical concepts clearly to designers and operational teams. Our delivery model actively integrates advanced automation, so you will help restructure how our front-end code is produced, reviewed, and delivered around intelligent systems to accelerate deployment cycles. Beyond mentoring less experienced peers, you will build MCP servers and multi-step transactional workflows to expose e-commerce APIs directly to large language models.

The Stack

You bring extended experience implementing software in React and TypeScript, backed by a solid mastery of design systems and cloud deployment across platforms like AWS.
You have structurally changed how your team works around AI, building shared systems like MCP servers or multi-step transactional workflows with LangChain that other developers depend on, raising the technical bar for the entire team.
You have a proven track record of technically leading a team with a delivery-focused mindset, executing drama-free launches, and consistently reducing process complexity.
You champion understandable, clean, and testable code, empowering your team to drive technical validation and automated testing to ensure the stability of business-critical systems.
You possess strong computer science fundamentals and a natural ability to guide your peers through hands-on mentorship, show-and-tell sessions, and technical proposals.

Why Plusgrade

Travel is about the moments that make a journey feel personal. At Plusgrade, we build the technology that makes those moments possible, from upgrade offers and loyalty experiences to revenue tools used by 575+ airline, hospitality, cruise, rail, and financial services partners worldwide.

The work is global, complex, and rewarding. You will solve meaningful problems, take ownership from idea to outcome, and work alongside people who are smart, curious, and committed to doing great work.

We also give our teams access to AI tools and the encouragement to use them thoughtfully, to move faster, explore ideas, and build better ways of working.

We trust our teams to do their best work. That means autonomy, flexibility, and room to grow.

Come help us shape the future of travel.

Développeur·euse logiciel front-end senior

Plusgrade conçoit les applications web élégantes et modernes permettant aux passagers du monde entier d'acheter des surclassements, et nous recherchons une personne prête à mener l'architecture front-end de nos prochains produits de voyage.

Ce que tu feras

Tu prendras en charge le développement et l'architecture d'applications web modernes avec React pour livrer des produits de haute qualité à temps. Tu dirigeras des discussions techniques devant un tableau blanc, simplifieras les systèmes complexes et traduiras des concepts techniques clairs pour les concepteurs et les équipes opérationnelles. L'intégration de l'IA fait partie intégrante de notre modèle opérationnel, ce qui signifie que tu participeras à la restructuration de la production, de la révision et de la livraison de notre code front-end pour automatiser et accélérer nos cycles de déploiement. En plus d'encadrer les développeurs moins expérimentés, tu concevras des serveurs MCP et des flux transactionnels pour connecter nos API e-commerce à des modèles de langage avancés.

La stack technique

React · TypeScript · MCP (Model Context Protocol) · AWS Bedrock AgentCore · LangChain · LangGraph · AWS ECS · AWS EKS · GCP · Docker · Datadog · Java · Springboot · CloudWatch · New Relic

Ce que tu apportes

Tu possèdes une expertise approfondie de React et TypeScript, combinée à une solide maîtrise des systèmes de conception et des architectures cloud sur AWS.
Tu as structurellement changé la façon dont ton équipe collabore autour de l'IA, en mettant en place des systèmes partagés comme des serveurs MCP ou des flux orchestrés avec LangChain que d'autres développeurs utilisent, élevant ainsi le niveau technique global.
Tu as déjà mené une équipe technique avec une culture axée sur la livraison, la réduction de la complexité des processus et l'exécution de déploiements fluides.
Tu écris un code propre, lisible et hautement testable, tout en poussant ton équipe à prioriser la validation technique et les tests automatisés pour garantir la stabilité des systèmes critiques.
Tu as d'excellentes bases en informatique et une capacité éprouvée à guider tes pairs par le mentorat, les sessions de démonstration et le partage actif de compétences.

Pourquoi Plusgrade

Le voyage, c'est avant tout les moments qui rendent chaque trajet unique. Chez Plusgrade, nous bâtissons la technologie qui rend ces moments possibles, des offres de surclassement et expériences de fidélisation aux outils de revenus utilisés par plus de 575 partenaires dans les secteurs aérien, hôtelier, des croisières, ferroviaire et des services financiers à travers le monde.

Le travail est mondial, complexe et valorisant. Tu résoudras des problèmes concrets, tu prendras en charge des projets de l'idée jusqu'au résultat, et tu travailleras aux côtés de personnes intelligentes, curieuses et engagées à faire un travail de qualité.

Nous donnons aussi à nos équipes accès à des outils d'IA et les encourageons à les utiliser de manière réfléchie, pour aller plus vite, explorer des idées et bâtir de meilleures façons de travailler.

We trust our teams to do their best work. Cela signifie autonomie, flexibilité et espace pour grandir.

Viens bâtir l'avenir du voyage avec nous.

Ce que tu aimeras chez nous
