Full job description

About Us!

We are a product-driven team focused on building custom software solutions that solve real business problems. We work closely across engineering, product, and design to create scalable systems, internal tools, and data driven platforms that deliver real impact. Our culture values speed, ownership, and practical execution, allowing us to turn complex ideas into production ready solutions quickly.

We are currently looking for a Senior Full Stack Engineer to reinforce a small, high-agency team. Our team is composed of builders and doers who take full ownership of both output and outcome, shaping products based on stakeholder requirements, deep experience, and the cutting edge of technology.

About The Role

As a Senior Full Stack Engineer, you will take ownership of features across the entire application lifecycle, moving away from a traditional siloed approach to a true 'you build it, you run it' mentality. You will have deep expertise in the development domain and have sufficient touch-points across everything from developer experience to service-level objectives.

While you will build modern, high-performing frontend interfaces using React 19+ and Next.js, you will also architect backend components, build data pipelines, manage infrastructure as code, and ensure long-term platform reliability. We value an abstract understanding of engineering principles over specific tool syntax, looking for someone who can easily master and apply core concepts to any framework.

You Will:

Drive Full-Stack Features: Build performant, accessible, and maintainable full-stack features using React 19+ and Next.js, spanning UI components, server components, route handlers, and API layers.
Develop Backend & Data Pipelines: Build and maintain scalable backend logic and data pipelines leveraging tools like AWS Lambda and Next.js.
Own Platform & DevOps Automation: Manage and automate process and release workflows, continuous integration via GitLab, and Platform Ops using Infrastructure as Code (IaC) with AWS CDK or Terraform.
Shape UI Foundations: Evolve our design system based on Atomic Design principles (atoms molecules organisms templates pages), writing clean, component-level styles.
Ensure Testing & Reliability: Implement comprehensive application testing (unit, integration, and e2e testing).
Monitor & Debug Systems: Set up and maintain application monitoring using Sentry and AWS CloudWatch, and perform distributed debugging by tracing issues through all involved domains.
Measure Outcomes: Own SLO measurement and reporting using tools like Mixpanel to ensure high platform performance and user satisfaction.
Collaborate & Review: Participate in requirements engineering within agile workflows, lead code reviews, provide structured feedback, and drive architectural choices via RFC processes.

You Have:

Full-Lifecycle Experience: Proven experience across the full application stack and lifecycle, starting with developer experience (code quality and productivity tools) all the way through production deployment.
Strong Engineering Abstraction: A deep, abstract understanding of engineering principles, tools, and frameworks, with a proven ability to learn abstract concepts and apply them across different tools.
Frontend Expertise: Deep hands-on experience with modern frontend development using Next.js, React 19+, and component architectures built on Atomic Design methodology.
Backend & API Mastery: Strong experience building and consuming APIs, establishing data contracts, and managing backend systems or data pipelines.
DevOps & Platform Fundamentals: Practical experience with process automation, CI/CD pipelines (e.g., GitLab), and managing infrastructure through IaC tools like AWS CDK or Terraform.
Observability Mindset: Experience setting up application monitoring (e.g., Sentry, CloudWatch) and using distributed debugging techniques across multiple architectural layers.

Nice-to-Have:

Strong Communication & Documentation: Proven experience writing and maintaining clear documentation, progress reports, and structured requests for changes, with the ability to seamlessly interface with specialized internal teams, external design/dev partners, and service providers.
Agentic Coding Stacks: Experience building, shaping, or maintaining AI and LLM agents for coding, including writing rulesets and skills to ensure they fulfill clean code requirements.
Real-Time Data Systems: Experience working with or building systems using WebSockets, pub/sub architectures, or other asynchronous communication patterns.
Interactive Canvas & Graphics: Experience with interactive 2D/3D Canvas experiences, game engines, data visualization, or gamification elements.
High-Scale Platforms: Experience scaling production platforms to support 100k+ users.

Time Zone Requirements:

Ability to attend regular syncs with EU team members before 9 am Eastern Time Zone.

Job Types:

Permanent, Full-time
Schedule: Monday to Friday

Pay:

$130K to $170K CAD per year

We Offer:
