Downtown Montreal - Hybrid

Full-time - Permanent

About the team

You'll join a small, senior, AI-augmented data engineering team at BCA Research. We build internal tools, automate manual workflows, and support the data pipelines that power a financial-research product real subscribers rely on. We move quickly because Claude Code, Codex, and similar tools are first-class members of our workflow - but we still own every line of code, review every PR carefully, and talk through tricky problems together on camera.

We're hiring a Python Developer to grow with the team.

Responsibilities
  • Deliver JIRA tickets end-to-end: Python tooling, data workflow automation, pipeline support, bug fixes, and reliability improvements
  • Use AI coding assistants daily, review their output critically, and keep the quality bar high
  • Write clean, maintainable Python with clear structure, type hints, appropriate tests, and readable documentation
  • Build automation that reduces manual work, improves data quality, and makes internal users more effective
  • Work with SQL and data stores to inspect, transform, validate, and troubleshoot data
  • Contribute to production data pipelines under the guidance of senior engineers and gradually take on larger areas of ownership
  • Debug unfamiliar systems using logs, queries, tests, and careful investigation
  • Collaborate with developers, data specialists, researchers, and project managers to turn operational problems into reliable software
  • Read relevant technical documentation before changing code; update documentation before opening the PR
  • Review teammates' PRs and take feedback well on your own


Required
  • 3-5 years of production engineering experience, with shipped work you can discuss clearly
  • Strong Python development skills, including experience building tools, scripts, services, or data workflows
  • Hands-on experience with AI coding assistants such as Claude Code, Cursor, Copilot, Codex, Cline, or similar
  • Comfortable with SQL for querying, debugging, validating, and transforming data
  • Familiarity with Git, command-line workflows, pull requests, and working in a shared codebase
  • Experience writing automated tests and debugging production or production-like issues
  • Ability to automate tedious or error-prone manual processes and understand the system underneath them
  • Adaptable across changing priorities, including internal tooling, pipeline support, ad-hoc data work, and platform improvements
  • Clear written and verbal communication with both technical and non-technical teammates
  • Excellent spoken and written English as you will collaborate with colleagues in Canada, US and globally.
  • Professional level of French spoken and written.


Nice to have
  • Experience with Microsoft Fabric, Azure, or cloud-based data platforms
  • Exposure to MongoDB or other document databases
  • Experience with data pipeline reliability, DataOps, or ELT/ETL workflows
  • Familiarity with financial data, market data, or vendor data feeds
  • Experience working in a monorepo
  • Experience with Python packaging and dependency tools such as uv
  • Performance and reliability instincts - observability, retries, validation, failure modes, and data quality checks


How we work
  • AI-first, human-owned. Every PR has a person's name and judgement behind it.
  • Documentation lives in the repo and is updated with the code, not after.
  • We value practical automation that removes real operational friction.
  • PR reviews are real reviews; automated agents and humans both have to be satisfied.
  • We work closely with internal users and iterate based on how tools are actually used.
  • Camera-on, engaged in collaboration when the team is on a call.

*Please note that the candidate must be located in the greater Montreal area. Candidate must be available full-time as this is a permanent role within the tech team.
