Full job description

RouteThis is on a mission to revolutionize technical support. We build AI-powered solutions that help Internet Service Providers and Smart Home companies solve connectivity and WiFi problems—before the subscriber ever needs to call.

Our customers already benefit from our SaaS solutions today and we aim to magnify that value by building autonomous agents into our solutions. As we continue to advance our mission, we’re looking for a Senior Data Engineer who thrives at the intersection of data engineering and systems architecture.

We care deeply about our technology, resolving customer pain points, and getting stuff done fast and are looking for people who share these values and are ready to execute against them every day.

What You'll Do:

Define and evolve our data modeling patterns across the platform
Ensure data is structured, accurate, and ready for high-impact reporting
Design and build resilient data pipelines using strong engineering best practices
Implement schema validation, enforce data integrity, and build automated tests to maintain trust
Own features end-to-end, from development through deployment
Build Node.js services running on EKS and Lambda
Define infrastructure using Terraform and ship via GitHub Actions
Improve and scale our real-time ingestion pipelines using Kinesis and Firehose
Drive efficiency, performance, and reliability across our data flow
Mentor co-ops and junior developers on database fundamentals, schema design, and data modeling
Help teammates build consistent and reliable systems within our AWS ecosystem
Guide best practices for DynamoDB access patterns and Snowflake integrations
Promote strong DevOps and CI/CD habits across the team

What You Bring:

Strong software engineering fundamentals in TypeScript/Node.js
High level of comfort using Python for data-intensive tasks
Experience designing systems, not just writing code
Comfortable working across NoSQL (MongoDB, DynamoDB) and relational/OLAP (Snowflake) data models
Hands-on experience with Kubernetes (EKS), Terraform, and modern CI/CD workflows
Confident operating across both application and infrastructure layers
Strong instincts for data integrity and quality
Experience using dbt or similar tools to transform and validate data
Comfortable working across the stack to unblock issues
Able to debug APIs, investigate data pipelines, and optimize Snowflake queries as needed

Our Stack:

We use AWS (EKS, Lambda, Dynamo, RDS), OpenAI, Elevenlabs, Snowflake, Node.js, Python, React, Android, and iOS. You don’t need to know it all, but you should be comfortable picking up new tools fast.

Package Overview:

The total compensation range for this role is $120,000 - $170,000 CAD.
Benefits through Manulife - Medical, Dental
Employee Assistance Program
Equity- Stock Options
3 weeks vacation plus an additional 10 days around statutory holidays to make long weekends longer!
