Job description

Job Description

On behalf of our client, a Vancouver-based digital consulting firm specializing in custom digital products and platforms, we are seeking a Senior Fullstack Developer to join a highly collaborative, craftsmanship-focused delivery team.

Our client partners with ambitious organizations to architect, design, and build complex digital products, including web platforms, mobile applications, and AI-enabled solutions. Their teams work in close, embedded collaboration with clients, leading discovery, validating early, and making thoughtful trade-offs to deliver high-quality, maintainable software.

This role is based in the Greater Vancouver Area and follows a hybrid model (minimum three days per week in office).

The Role

As a Senior Fullstack Developer, you will be responsible for building production-grade applications end-to-end, from backend API design through frontend delivery. You will take ownership of technical execution across multiple client products, working closely with Product Owners, Designers, and Engineers.

This is not a heads-down feature factory role. The ideal engineer combines strong technical fluency with product judgment, clear communication, and a consulting mindset. They treat collaboration, documentation, and trade‑off discussions as core parts of the craft.

The successful candidate will be comfortable working across multiple engagements, balancing delivery speed with code quality, and helping clients navigate complex technical decisions while maintaining clear, maintainable systems.

What You’ll Do

Engineering & Code Quality

• Architect, develop, and deploy production-grade fullstack features using modern TypeScript-based stacks.
• Make sound architectural decisions balancing performance, scalability, security, and delivery timelines.
• Address technical debt pragmatically while maintaining delivery momentum and codebase integrity.
• Document non-obvious technical decisions through PRs, ADRs, or concise design notes.

Code Review & Collaboration

• Conduct thoughtful PR reviews that explain why changes are recommended, not just what should change.
• Maintain strong Git hygiene and disciplined branching, merge, and review practices.
• Contribute to shared engineering standards and help elevate teammates through mentorship and knowledge sharing.

Client & Product Partnership

• Work closely with Product Owners and Designers to ensure technical decisions align with business and user goals.
• Communicate risks, trade‑offs, and technical constraints clearly, including to non-technical stakeholders.
• Challenge assumptions, surface blockers early, and engage with the "why" behind features rather than only executing requirements.

Cloud, DevOps & AI-Assisted Development

• Build and support workloads on AWS or Azure with reliability and security treated as foundational.
• Work within modern CI/CD, containerization, and infrastructure-as-code practices.
• Leverage AI tools such as Copilot, Cursor, or Claude Code as part of daily development workflows.
• Help shape team standards and best practices around AI-assisted development.

Experience

What You Bring

• 7+ years of professional fullstack development experience.
• Strong record of architecting, shipping, and maintaining production-grade applications.
• Experience working in consultancy, agency, or other client-facing environments is highly desirable.
• Comfortable context-switching across multiple projects while maintaining strong execution quality.

Technical Fluency

• Deep fluency in the TypeScript ecosystem across the full stack.
• Hands‑on experience with Node.js / Express on the backend and React on the frontend.
• Strong understanding of engineering fundamentals including asynchronous patterns, error handling, scalability, and performance optimization.
• Practical experience working with relational and/or document-based databases.
• React Native experience supporting production mobile applications is a strong asset.

Cloud & Tooling

• Working knowledge of AWS or Azure.
• Familiarity with CI/CD pipelines, containerization, and infrastructure-as-code practices.
• Proficiency with GitHub, GitLab, Jira, ClickUp, or similar collaboration tools.

Communication & Mindset

• Strong written communication through documentation, PRs, ADRs, and technical notes.
• Comfortable explaining technical trade‑offs clearly and calmly.
• Ownership mindset focused on outcomes, not just tasks.
• Values craftsmanship, sustainable delivery, and clarity over speed alone.

Who You Are

You are a senior engineer who takes pride in building maintainable software and making thoughtful technical decisions. You are comfortable operating in ambiguous environments, asking questions when something is unclear, and balancing business goals with engineering excellence. You enjoy learning, experimenting with new tools, and helping raise the standard for those around you.
