Job summary

Dialogue is seeking a Senior Data Platform Developer to design, build, and maintain a modern data platform. You will define best practices across ingestion, transformation, and consumption to empower power users with data products and faster insights.

You’ll partner with Product, Sales, Ops, Finance and more to onboard power users into a self-serve model and collaborate with vendors to improve data tooling. Hybrid work in Montreal or Toronto is available.

Qualifications

• 3+ years of experience in building production data systems, with deep expertise in large-volume data pipelines, databases and real-time events.
• Strong experience with data warehouse modelling, performance optimization and semantic layer development. Ability to design, optimize and provide guidance on building scalable data products.
• Strong background with Snowflake and dbt.
• Proficiency with Apache Airflow for workflow management and building resilient pipelines.
• Experience synchronizing data from multiple data sources such as SaaS, Cloud DB’s, APIs and event streams.
• Advanced SQL skills and strong software engineering skills in Python.
• Experience embedding data validation, data observability and idempotent design into deployment pipelines. Familiarity with tools like Datadog or Elementary or Soda.
• Hands‑on experience using AI tools to automate repetitive data workflows such as model and semantic layer development, versioning and deprecation.
• Hands‑on experience setting up continuous integration and deployment workflows using CircleCI or GitHub Actions for data repositories.
• Proven track record managing cloud resources and environments using Terraform.
• You take pride in what your team accomplishes, not just your individual output, and communicate with clarity and openness.
• The ability to clearly articulate technical designs, project status, and risk to both technical peers and non-technical stakeholders.

Responsibilities

• Data Ingestion & Orchestration: Design scalable ingestion frameworks for batch and streaming data. This can be standard SaaS sources, API end points, internal DB’s or our own event system. Orchestrate robust and resilient data pipelines utilizing Airflow (with opportunity to evaluate/implement workflows with Temporal).
• Data Modelling & Semantic Layer Development: Define and enforce data modelling standards - including dimensional modelling, semantic layer development and streaming analytics. Enable software and analytics engineers to author their own transformations to production-grade standards.
• Data Quality & Observability: Embed data validation, testing, and observability into every stage of the pipeline - from ingestion through transformation to consumption. Define testing standards for dbt models, set up monitoring and alerting to ensure data products fail loudly and actionably rather than silently.
• AI-Assisted Engineering Workflows: Design and implement AI-assisted workflows to accelerate repetitive data product development lifecycle and ensure AI agents have accurate context and sufficient guardrails for analytics.
• CI/CD & Infrastructure as Code: Provision, manage, and scale infrastructure using Terraform. Build and maintain robust CI/CD pipelines using CircleCI for automated testing, PR checks, validation, and deployment.
• Data Storage & Access Control: Optimize our Snowflake warehouse for performance and cost efficiency. Implement granular Access Management, column-level masking, and strict data governance policies.
• BI Tool Ownership: Own Evidence as a deployed tool - infrastructure, hosting, Snowflake connectivity, upgrades, and CI/CD. Enable teams to build and deploy their own data products on it.
• Shared Technical Leadership: Partner with our developers sharing context, translating ambiguous requirements into clear architecture, aligning on technical decisions collaboratively, and building on each other’s work.
• Non-Technical User Enablement: Guide software and analytics developers on adopting production-grade standards; create documentation and tooling that makes adherence the path of least resistance. Train and up skill data power users so they can independently build, deploy, and maintain data products.
• Own the full lifecycle. Operate in a full DevOps model - development, testing, operations, observability and support for the systems you build. Participate in code reviews and technical design discussions to ensure high-quality of team output.
