What is a senior web developer?

A senior web developer is a highly skilled computer coding professional with fluency in languages such as HTML, JavaScript, and CSS. In this career, your responsibilities include designing, developing, and debugging the backend of software programs for websites, applications, tools, and databases. You also work with JavaScript frameworks, develop tests using testing frameworks, help build and deploy automation scripts, troubleshoot, and resolve app performance issues. As a senior web developer, you may supervise a team of developers and collaborate with user experience designers to determine what the frontend user experience and website layout will look like during the design phase. Other duties may include enforcing coding standards, reviewing the work completed by your team, managing the budget and project schedule, and communicating directly with clients.

What are the key skills and qualifications needed to thrive as a senior web developer, and why are they important?

To thrive as a Senior Web Developer, you need advanced proficiency in programming languages like JavaScript, HTML, CSS, and backend frameworks, supported by a bachelor’s degree in computer science or equivalent experience. Expertise in tools such as version control (Git), CI/CD pipelines, and knowledge of modern frameworks (React, Angular, Node.js) are typically required, along with relevant certifications. Strong problem-solving ability, effective communication, and leadership skills help you collaborate across teams and mentor junior developers. These competencies ensure high-quality, scalable web solutions and support successful project delivery in dynamic development environments.

What are some common challenges faced by senior web developers when leading project teams?

Senior Web Developers often encounter challenges such as balancing hands-on coding responsibilities with mentoring junior team members and ensuring project deadlines are met.

Effective communication with designers, backend developers, and project managers is essential to align technical solutions with business goals. Successfully managing these aspects leads to smoother project delivery and professional growth.

Job description

Alteo is looking for a Senior Web Developer for a permanent position. The company is located in the Greater Montreal area.

*** 100% Remote - Excellent working conditions ***

Reporting to the VP of Technology, you will collaborate with teams across software engineering, data science, regulatory, security, and external partners to deliver secure and scalable solutions.

You will be responsible for building and delivering production-ready web applications. You will be a core contributor to the company web sites, built with TypeScript, React, and a Node.js/Fastify API backed by PostgreSQL. Beyond the core web sites, you will also contribute to other product-level initiatives across the organization, helping connect web experiences with the broader ecosystem products and integrations.

Your curiosity, desire for continuous learning, and self-improvement will play a key role in your success.

Responsibilities:

> Hands-on Web Developement

  • Front end: Build and maintain responsive, accessible interfaces for the company portal using React 19, React Router 7, and Vite, written in TypeScript with i18n localization support.
  • Back end: Develop and maintain API services using Node.js and Fastify 5 (TypeScript), following a clean routes → controllers → services architecture, with request/response validation.
  • Data layer: Work with PostgreSQL, contributing to schema design, migrations, and query performance within our schema-controlled migration workflow.
  • Shared contracts: Evolve the shared schemas package (Drizzle schemas, Zod validation, endpoint constants, and types) that serves as the single source of truth across the front end and API.
  • Quality: Write and maintain tests with Vitest (front end) and Jest (API), reuse shared fixtures, and document components.

> Integration and Product-Level Contribution

  • Third-party integrations: Build and maintain integrations with Stripe (payments/billing), AWS services (S3, SES, SSM), HubSpot (CRM sync), SCORM Cloud, and partner platforms via webhooks and typed API boundaries.
  • Cross-product work: Contribute to other product-level projects — connecting the web platform to cognitive assessment products, supporting new feature initiatives, and helping shape shared tooling and patterns used across teams.
  • Reliability: Help maintain existing products to ensure maximum uptime and continuously assess opportunities for improvement.

> Team Collaboration

  • Work with internal and external development teams, conduct code reviews, and foster best practices in code quality, testing, and documentation.
  • Collaborate with product managers and stakeholders to translate requirements into technical deliverables.
  • Thrive in a small-team environment where ownership and initiative are valued.

> Innovation and Continuous Improvment

  • Stay current with emerging trends in web frameworks, TypeScript tooling, and cloud development.
  • Advocate for process improvements, tooling, and automation to boost team productivity.

Profile:

  • DEC/BAC in IT or equivalent
  • 5-8+ years experience in Web Development
  • Strong proficiency in TypeScript and modern React (hooks, component architecture, state management).
  • Solid back-end experience with Node.js and a modern framework (Fastify, Express, NestJS, or similar) and RESTful API design.
  • Hands-on experience with relational databases (PostgreSQL preferred) and an ORM/query builder such as Drizzle, Prisma, or TypeORM.
  • Experience building and consuming typed API contracts and validating data (e.g., Zod).
  • Comfortable with Git-based workflows, code review, automated testing, and CI/CD.
  • Excellent communication skills and the ability to work independently in a small, fast-paced team.
  • Familiarity with Agile methodology
  • Good problem-solving skills and attention to detail
  • Team player, dedicated, positive attitude

> Nice to have:

  • Experience with Vite, React Router (framework mode), Supabase, or Storybook.
  • Experience integrating Stripe, AWS (S3/SES/SSM), HubSpot, or e-learning standards such as SCORM.
  • Familiarity with Docker, Terraform, and GitHub Actions.
  • Basic understanding or experience developing solutions in a regulated industry (GDPR, HIPAA, PIPEDA).
  • Exposure to monorepo architectures and shared-contract / design-system patterns.
  • Experience with Webflow.

> Intégration et contribution au niveau des produits

  • Intégrations tierces : Développer et maintenir des intégrations avec Stripe (paiements/facturation), les services AWS (S3, SES, SSM), HubSpot (synchronisation CRM), SCORM Cloud et les plateformes partenaires via des webhooks et des limites d'API typées.
  • Travail inter-produits : contribuer à d’autres projets au niveau des produits — en connectant la plateforme web aux produits d’évaluation cognitive, en soutenant les initiatives de nouvelles fonctionnalités et en aidant à façonner les outils et modèles partagés utilisés par toutes les équipes.
  • Fiabilité : aider à maintenir les produits existants pour garantir une disponibilité maximale et évaluer en permanence les opportunités d’amélioration.

> Collaboration en équipe

  • 5 à 8 ans d’expérience ou plus en développement web
  • Maîtrise approfondie de TypeScript et de React moderne (hooks, architecture des composants, gestion de l’état).
  • Solide expérience back-end avec Node.js et un framework moderne (Fastify, Express, NestJS ou similaire) ainsi que la conception d’API RESTful.
  • Expérience pratique des bases de données relationnelles (PostgreSQL de préférence) et d’un ORM/générateur de requêtes tel que Drizzle, Prisma ou TypeORM.
  • Expérience dans la création et l’utilisation de contrats API typés et la validation de données (par ex., Zod).
  • À l'aise avec les workflows basés sur Git, la revue de code, les tests automatisés et le CI/CD.
  • Excellentes compétences en communication et capacité à travailler de manière autonome au sein d'une petite équipe dynamique.
  • Connaissance de la méthodologie Agile
  • Bonnes compétences en résolution de problèmes et souci du détail
  • Esprit d'équipe, dévouement et attitude positive
