Junior Data Scientist

The opportunity:

The Canadian Resident Matching Service (CaRMS) is seeking a driven engaged and inquisitive Junior Data Scientist with a passion for building critical data infrastructure and applying data science to support decision-making. Reporting to the Lead Data Scientist this position will support CaRMS data strategy through the design implementation maintenance and expansion of a new data platform using a data stack employing PostgreSQL and Python (SQLAlcemy/SQLModel Dagster and FastAPI).

This is afull-time permanent position that is fully remote. The successful candidate must be based in Canada and have the ability and willingness to travel if required. The language requirement for this role is either English essential or bilingual (English and French). Occasional overtime may be necessary to meet critical deadlines.

Your impact:

CaRMS uses data to answer important internal and external stakeholder questions related topolicy match participant preferences and match outcomes generated by the matching algorithm. As your domain knowledge of the matching business develops you will increasingly contribute data-driven insights for both internal teams and external clients.

As part of asmall collaborative team you will be heavily involved in data engineering and hands-on technical work. You will contribute to the design implementation and operation of core data infrastructure including systems that:

• Update and maintain the corporate Data Warehouse
• Exchange data with the matching software
• Generate data products and services

Initially your primary focus will be themodernization of the internal platform used to run the matching algorithm. Working closely with the Lead Data Scientist you will help rebuild and enhance ETL processes that prepare inputs for the match algorithm and process its outputs.

The role and responsibilities:

Data Engineering

• Designing implementing and operating critical data infrastructure including systems for updating the corporate Data Warehouse passing information to and from our matching software and generating data products (operational reporting data contracts match statistics etc.)
• Migrating ETL associated with passing information to and from the matching software from Informatica PowerCenter to new PostgreSQL/Python-based data platform (PostgreSQL SQLAlcemy / SQLModel Dagster and MkDocs)
• Developing internal matching platform API (using FastAPI) to run ETL associated with the matching software and help application developers use it
• Consolidating overlapping SQL views across data products to ensure consistency
• Developing modular Python-based reporting framework for producing data contracts operational reporting and custom data requests

Data Science

• Maintaining and extending match simulation software and conducting what-if scenario analysis for stakeholders in collaboration with the Lead Data Scientist
• Contributing to R markdown/Quarto-based insight research pieces for internal and external stakeholders
• Helping our stakeholders understand applicant and employer preferences (preference modeling)
• Developing better ways to help our clients find their ideal candidates/residency positions (for use in our broader web application)

Qualifications:

• Four-year degree in data science economics computer science engineering applied mathematics statistics or equivalent work experience.
• Very strong proficiency in Python and advanced SQL skills is required.
• 3-5 years of experience with Python-based data engineering / data science packages (particularly SQLAlchemy/SQLModel pandas Dagster FastAPI and LangChain).
• Experience using cloud data storage (AWS S3) PostgreSQL-compatible database services (i.e. fully managed through RDS / Aurora or self-managed on Amazon EC2) and compute (EC2 ECS Fargate) is very highly valued.
• Significant experience with relational database systems (e.g. Oracle PostgreSQL etc.).
• Deep understanding of data management concepts associated with designing building maintaining and extending an Enterprise Data Warehouse.
• Use of version control (Git) and test-based development practices should be strongly engrained in your workflow
• Practical experience with any of the following is valued:
  • Implementing semantic search and Q&A on documents.
  • Computational statistics particularly resampling techniques.
  • Matching algorithms
  • Informatica PowerCenter.
  • Using Quarto/R markdown to produce reproducible reporting.
  • Developing and supporting dashboards (e.g. Tableau MS Power BI etc.).
  • Jira and Confluence collaboration tools.

The successful candidate:

Our ideal candidate requires very strong Python-based data engineering skills.You are a highly organized detail-oriented and analytical individual who is a self-starter with a high degree of initiative. You are internally driven to continually hone your data engineering/data science skills. You can produce strong results within tight deadlines. You have strong communication skills (in English) and can clearly convey pertinent information to internal stakeholders at the appropriate level of detail. Your strong team orientation enables you to work with multiple departments to meet their data needs. You have the exceptional problem-solving skills required to deliver effective data solutions for our clients. You may be an early career data engineer looking to break into data science.

How do you stand out

To stand out you must show us your work. We are modernizing our infrastructure using PostgreSQL SQLAlchemy/SQLModel Dagster and FastAPI. We have made public-facing CaRMS data scraped from our website available in an easily consumable format on the personal GitHub account of our Lead Data Scientist Derek Nokes (dnokes/Junior-Data-Scientist: Public-facing CaRMS data scraped from the CaRMS website.). Use it to show us your data engineering data science and/or visualization skills. Use our stack and show us what you can do! Build something provide your project GitHub repository link in your application get an interview and present your work to us.
