Downtown Toronto (In-office / Hybrid model) They are building a high-volume data ingestion and API platform that serves as the backbone for major enterprise clients. By aggregating and standardizing massive streams of complex IoT and sensor data, their platform enables traditional industries to build real-time analytics and products. They are looking for senior-level backend engineers to join their Toronto hub to help architect the next phase of their growth.

The Role

This is a high-visibility, high-impact engineering role focused on the core product and API layer. You will be responsible for architecting the distributed systems that process continuous data feeds from hundreds of disparate external sources. Because you are building the foundation that both internal teams and external enterprise clients rely on, you will be deeply involved in product shaping, architectural decision-making, and direct technical consulting with end-users.

Lead the end-to-end design and deployment of robust, scalable backend services and public-facing APIs in a cloud-native AWS environment. Engineer fault-tolerant integration layers that reliably ingest, normalize, and process unpredictable data from a wide variety of third-party vendors. Interface directly with enterprise clients and partners to map out integration strategies,



resolve complex technical roadblocks, and understand user needs.

Champion engineering standards and introduce modern, automated tooling to scale development velocity.

Technical Stack: Deep production expertise in TypeScript and Node.js. A robust track record of taming messy, complex external APIs and turning them into reliable, clean data pipelines. Customer-Facing Aptitude: You are not looking to hide in the backend. You enjoy being on implementation calls and acting as a technical authority for enterprise customers.

Autonomy: You thrive in ambiguous environments, can scope complex projects independently, and have the judgment to balance technical perfection with business velocity.

Bonus Qualifications

Experience with event-driven or serverless architectures in AWS. Exposure to JVM languages is a plus for cross-functional collaboration with data platform teams.

Predominantly

On-Site: The engineering team strongly believes in the velocity of in-person collaboration and operates out of a downtown Toronto office 4 days a week. Includes top-tier health/dental coverage, generous wellness and professional development stipends, modern hardware, and 4 weeks of paid time off. #
