About Stay22

Based in Montreal, Stay22 helps ambitious creators and intent-rich digital platforms turn their existing traffic into incremental revenue, with technology that works quietly in the background.

Today, more than 6,500 creators and platforms rely on Stay22, with over $1 billion in annual transactions flowing through the platform. Originally built for travel, the company now supports partners across retail, lifestyle, publishing, events, and transport as it expands its monetization infrastructure for the modern creator economy.

About the role

As a Senior Fullstack Developer on the Phantom team, you will play a key role in advancing our embedded widget and affiliate platform. Your mission will be to streamline browser execution and ensure high performance of our scripts across diverse websites.

You will design mechanisms for privacy-conscious session tracking and fingerprinting, and take ownership of the full script lifecycle – from load optimization to event handling and error recovery. Working closely with product and engineering leads, you will help shape and maintain the core infrastructure that powers Stay22's embeddable products, ensuring they run reliably under real-world constraints.

Key Responsibilities

Continuously improve the load time and execution efficiency of our browser scripts (minification, caching, lazy loading, etc.)
Create robust methods for injecting content and widgets into arbitrary websites (e.g. automating DOM manipulation, handling dynamic page layouts)
Architect and execute A/B/n experimental setups alongside analytics teammates, leveraging data metrics to guide key product shifts
Solid grasp of Express.js middleware and user session administration, applying core security principles to server-side code
Build and maintain Node.js/Python-based scrapers to collect data from partner websites or APIs when needed; design fallback data sources for resiliency
Troubleshoot and adapt our runtime logic for real-world usage, including handling unexpected page structures or third-party script conflicts
Own the entire embedded product stack (scripts, SDKs, APIs) and collaborate with other teams to integrate updates and new features smoothly

Requirements

Deep hands-on experience with vanilla and ES6+ JavaScript or TypeScript without relying on frameworks (no React/Vue/etc. for core logic)
Strong knowledge of the browser event loop, DOM API, CSSOM, rendering pipeline, and how to optimize for First Contentful Paint (FCP), Largest Contentful Paint (LCP), etc.
Proficiency with Node.js for building APIs and web scrapers; experience with Python-based scraping is a plus. Familiarity with HTTP, REST/JSON, and proxies
Understanding of browser fingerprinting methods and privacy considerations (e.g. cookie/session management, CORS, GDPR). This is a big asset
Public contributions on GitHub or other open-source involvement (project contributions, libraries) are strongly preferred
Bachelor's or Master's in Computer Science (or equivalent) is a plus, or equivalent professional experience in software development

What to Expect from our Hiring Process

We know your time’s valuable, so here’s the quick rundown of what to expect.

Screening call with our Talent Acquisition Advisor - virtual (20-30 minutes)

Tu élaboreras des dispositifs de suivi de session et de fingerprinting respectueux des exigences de confidentialité, tout en pilotant le cycle de vie complet du code client - de l'optimisation des temps de charge à la gestion des événements et à la résilience face aux erreurs. En synergie avec les responsables produit et ingénierie, tu participeras au façonnement et au maintien des fondations techniques qui alimentent les solutions Stay22, pour un fonctionnement irréprochable sur le terrain.

Responsabilités principales

Optimiser sans relâche la rapidité d'affichage et la légèreté d'exécution de nos scripts navigateur (minification, stratégie de cache, lazy loading)

Mettre en place et déployer des expérimentations A/B/n avec les spécialistes en analyse de données, en t'appuyant sur les indicateurs de performance pour guider les choix produit
Maîtriser les rouages des middlewares Express.js et du traitement des sessions utilisateur, tout en appliquant les normes de sécurité indispensables au code serveur
Développer et entretenir des outils de collecte en Node.js/Python pour extraire les informations des partenaires ou API au besoin, en prévoyant des flux secondaires de secours
Résoudre et ajuster notre logique applicative face aux anomalies du monde réel, notamment les dispositions de page inhabituelles ou les interférences avec d'autres scripts
Assurer la responsabilité complète du périmètre applicatif embarqué (scripts, SDKs, API) et coopérer avec les autres pôles pour intégrer harmonieusement évolutions et nouveautés

Exigences

Expérience concrète et approfondie en JavaScript vanilla et ES6+ ou en TypeScript, sans dépendance aux frameworks pour la logique principale (pas de React/Vue/etc. pour le cœur du système)
Solide connaissance de l'event loop du navigateur, du DOM API, du CSSOM, du pipeline de rendu, et des façons d'optimiser le First Contentful Paint (FCP), le Largest Contentful Paint (LCP), etc.
Maîtrise de Node.js pour la création d'API et de scrapers web; une expérience en scraping avec Python est un atout. Connaissance de HTTP, REST/JSON et des proxies
Compréhension des méthodes de fingerprinting du navigateur et des considérations liées à la vie privée (gestion des cookies/sessions, CORS, RGPD). C'est un atout important
Des contributions publiques sur GitHub ou une implication dans des projets open source (contributions, librairies) sont fortement souhaitées
Un baccalauréat ou une maîtrise en informatique (ou équivalent) est un atout, ou une expérience professionnelle équivalente en développement logiciel
