Payfacto
Développeur Full Stack Senior – Vue.js + Go / Développement AI-First
À propos de PayFacto
PayFacto est une entreprise de technologie financière en forte croissance, spécialisée dans les solutions de paiement et de point de vente (POS) pour les restaurants, hôtels et bars. Nous développons des plateformes SaaS critiques utilisées quotidiennement par des milliers de commerçants, combinant performance, fiabilité et excellence UX.
Nous recherchons aujourd'hui un développeur Full Stack senior d'exception pour jouer un rôle clé dans la conception et l'évolution de notre nouvelle plateforme cloud. Nous sommes une équipe de champions : nous cherchons quelqu'un du même calibre — un développeur qui a fait ses preuves sur des produits SaaS destinés aux clients, et qui a complètement réinventé sa façon de travailler autour de l'IA.
À propos du rôle
Ce poste est idéal pour un développeur chevronné qui souhaite avoir un réel impact produit, influencer les décisions techniques et contribuer à bâtir une architecture moderne et scalable, du frontend jusqu'au backend.
Le frontend demeure au cœur du rôle : vous travaillerez principalement sur des applications Vue 3 complexes et à fort volume. Mais votre portée ira au-delà de l'interface — vous développerez également nos APIs et services backend en Go, au sein de notre infrastructure cloud, en collaboration étroite avec les équipes produit et design. La combinaison Vue + Go est notre stack, et nous cherchons quelqu'un qui la maîtrise des deux côtés.
Nous sommes une organisation AI-first. Nous ne cherchons pas quelqu'un qui a « essayé quelques outils d'IA » : nous cherchons un développeur qui a transformé en profondeur sa manière de concevoir, coder, tester et livrer grâce à l'IA, et qui peut élever toute l'équipe à ce niveau.
Vos responsabilités
- Concevoir, développer et maintenir des applications frontend complexes avec Vue 3
- Développer nos APIs et services backend en Go pour notre plateforme cloud SaaS
- Participer aux décisions d'architecture full stack (state management, performance, structure des composants, services, intégrations)
- Traduire des besoins produit complexes en interfaces claires, performantes et maintenables, destinées à des clients réels
- Optimiser les performances, l'accessibilité et l'expérience utilisateur
- Incarner et promouvoir le développement AI-first : intégrer les outils et workflows d'IA dans tout le cycle de développement (conception, code, tests, revue, livraison)
- Élever le niveau technique de l'équipe par le mentorat, les revues de code et les bonnes pratiques
- Contribuer à l'évolution des standards d'ingénierie (tests, tooling, CI/CD)
Profil recherché
- 10+ ans d'expérience en développement logiciel, dont une expérience significative en full stack
- Excellente maîtrise de Vue.js 3 (Composition API, reactivity system, lifecycle, performance)
- Solide expérience de produits SaaS cloud destinés aux clients (customer-facing), à fort trafic ou critiques
- Très bonne connaissance de JavaScript / TypeScript, HTML5 et CSS moderne
- Solide expérience backend en Go (APIs, services, bases de données) — la combinaison Vue + Go est au cœur de ce rôle
- Développeur AI-first : vous avez repensé votre façon de travailler autour de l'IA — agents de codage, workflows assistés par IA, automatisation — et vous pouvez le démontrer, pas seulement en parler
- Solide compréhension des concepts avancés : state management, performance, architecture, testabilité
- À l'aise dans un environnement produit agile et collaboratif
Atouts importants
- Expérience avec Vue 2 (migration Vue 2 → Vue 3 est un plus)
- Expérience backend avec PHP, Laravel ou Symfony
- Expérience avec des systèmes de design, UI libraries ou design tokens
- Expérience approfondie des environnements cloud (AWS, Azure ou GCP)
- Bonne compréhension des pipelines CI/CD
Pourquoi nous rejoindre
- Impact direct sur des produits utilisés à grande échelle
- Liberté technique et influence réelle sur les choix d'architecture
- Environnement mature, mais en forte croissance
- Équipe internationale (Canada, États-Unis, Europe)
- Produits reconnus dans l'industrie (Veloce, Maitre'D)
Ce que nous offrons
- Assurance médicale et dentaire dès le jour 1
- Télémédecine 24/7
- REER avec contribution de l'employeur
- Vacances et congés personnels
- Télétravail
- Défis techniques stimulants dans une entreprise en croissance rapide

Senior Full Stack Developer – Vue.js + Go / AI-First Development
About PayFacto
PayFacto is a fast-growing fintech company delivering fully integrated POS and payment solutions to restaurants, hotels, and bars. Our SaaS platforms power mission-critical operations for thousands of merchants every day.
We are looking for an exceptional Senior Full Stack Developer to play a key role in building and evolving our next-generation cloud platform. We are a team of champions, and we're looking for someone of the same caliber — a developer with a proven track record on customer-facing SaaS products who has completely reinvented the way they work around AI.
About the role
This role is ideal for a highly experienced engineer who wants to own meaningful product areas, influence technical direction, and help build a modern, scalable architecture from the frontend all the way to the backend.
The frontend remains at the heart of this role: you will work primarily on complex, high-volume Vue 3 applications. But your scope goes beyond the interface — you will also build our backend APIs and services in Go, within our cloud infrastructure, in close collaboration with product and design teams. Vue + Go is our stack, and we're looking for someone who is strong on both sides of it.
We are an AI-first organization. We are not looking for someone who has "tried a few AI tools": we want a developer who has fundamentally transformed how they design, code, test, and ship using AI — and who can bring the whole team up to that level.
Responsibilities
- Design, build, and maintain complex frontend applications using Vue 3
- Build our backend APIs and services in Go for our cloud SaaS platform
- Drive full stack architecture decisions (component structure, state management, performance, services, integrations)
- Translate complex product requirements into clean, high-performing, customer-facing user interfaces
- Optimize performance, accessibility, and overall UX
- Champion AI-first development: embed AI tools and workflows across the entire development lifecycle (design, code, testing, review, delivery)
- Raise engineering standards through code reviews, mentoring, and best practices
- Contribute to engineering tooling, testing strategy, and CI/CD pipelines
About you
- 10+ years of software development experience, including significant full stack experience
- Deep expertise in Vue.js 3 (Composition API, reactivity system, lifecycle, performance)
- Strong track record building customer-facing, high-traffic or business-critical cloud SaaS products
- Strong proficiency in JavaScript / TypeScript, HTML, and modern CSS
- Strong backend experience in Go (APIs, services, databases) — the Vue + Go combination is at the core of this role
- AI-first developer: you have rebuilt your workflow around AI — coding agents, AI-assisted workflows, automation — and can demonstrate it, not just talk about it
- Solid understanding of advanced concepts: state management, performance, architecture, testability
- Comfortable working in Agile, product-driven environments
Nice to have
- Experience with Vue 2 and Vue 2 → Vue 3 migrations
- Backend experience with PHP, Laravel, or Symfony
- Experience with design systems, UI libraries, or design tokens
- Deep familiarity with cloud environments (AWS, Azure, GCP)
- CI/CD experience
What we offer
- Medical and dental coverage from Day 1
- 24/7 telemedicine
- RRSP matching
- Vacation and personal days
- Remote work
