Full job description

Sr. Software Engineer (Node.js, React)

We're looking for a senior engineer who can take ownership of complex systems, make sound technical decisions, and drive meaningful outcomes. You'll work across the full stack - backend services, frontend applications, infrastructure, and data - with significant autonomy over how problems get solved.

This isn't a role where someone hands you tickets. You'll assess tradeoffs, identify what matters, and ship solutions that move the business forward.

Key Responsibilities: 

Make technical decisions with business awareness - evaluate options, assess risks, understand downstream impact, and choose the right path - not just the clever one
Own systems end-to-end - from database schema to API design to UI, across multiple services
Analyze impact before acting - understand how changes propagate through interconnected services, data pipelines, and scheduled jobs before committing to an approach
Improve what exists - identify bottlenecks, reduce fragility, expand test coverage, and modernize legacy code pragmatically
Design for reliability - build systems that handle failure gracefully, with proper observability, error handling, and recovery
Set technical direction - establish patterns, review architecture, and raise the engineering bar for the team

  Tech Stack:

Backend: Node.js, Express, TypeScript
Frontend: React, Vite, Tailwind CSS
Databases: MongoDB, MySQL
Caching: Redis
Infrastructure: Docker, cloud deployment (DigitalOcean), Turborepo Monorepo
Scheduling: Cron-based job orchestration
Integrations: REST APIs, web scraping, proxy management

Technical Skills: 

Strong production experience with TypeScript/Node.js and Express
Solid skills across MongoDB and MySQL - schema design, query optimization, migrations
Experience building and maintaining React frontends
Hands-on with Docker, cloud infrastructure, and CI/CD pipelines
Experience with Monorepo architecture and multi-service systems
Demonstrated ability to make technical decisions independently - weighing tradeoffs, assessing blast radius, and communicating rationale clearly
Strong impact analysis skills - you think through second-order effects before making changes to production systems
Experience with web scraping, proxy rotation, and third-party API integration at scale
Familiarity with Redis caching and scheduled job orchestration

 Nice to Have:

Experience with AWS services (EC2, ECS, Lambda, RDS, S3, CloudWatch, or similar)
Familiarity with Kubernetes - container orchestration, deployments, scaling, and cluster management
Experience with observability platforms (Datadog or similar)
Background in e-commerce, marketplace integrations, or dynamic pricing systems
Experience leading small engineering teams

  AI Usage:

AI tools are a core part of how we work:

Claude Code and Cursor are used daily for development - code generation, refactoring, debugging, and architectural reasoning
We expect you to be proficient with AI-assisted development and use it to move faster without sacrificing quality
Experience applying AI/ML to business problems (optimization, forecasting, anomaly detection) is a plus

  Who You Are:

You think before you build. You ask "what breaks if this changes?" before writing code
You communicate decisions clearly - to engineers and to non-technical stakeholders
You take ownership of outcomes, not just tasks
You're pragmatic - you ship working solutions and improve iteratively rather than chasing perfection
You're comfortable with ambiguity and can turn vague problems into concrete plans

Job Type: Full-time

Pay: $90,000.00-$110,000.00 per year

Benefits:

Casual dress
Dental care
On-site parking
Paid time off
Tuition reimbursement
Vision care

Work Location: Hybrid remote in Markham, ON
