About Capital One Canada

For 30 years, we’ve been on a mission to change banking for good. We challenge the traditional bank stereotype, fostering a culture where innovation thrives and bold ideas are celebrated.

You’ll be empowered to grow your career in a supportive environment where you can own and shape your journey on your own terms. You’ll redefine what’s possible by contributing to work that impacts millions of Canadians, taking ownership of your decisions and outcomes, supported by mentors who will push you to think bigger and challenge the status quo.

Are you ready to redefine what’s next?

About the Team

Team Interstellar builds the core backend services for Capital One Canada. We focus on data quality, regulatory compliance, and customer service automation.

We manage four main systems.

The Canada KYC Compliance API validates customer data against anti-money laundering regulations. It handles high traffic to ensure accounts stay compliant and streams results for analytics.

The Canada Omilia Migration focuses on backend infrastructure for a natural language voice bot. This bot handles millions of calls annually. We are currently building automated testing frameworks and integrating the system into enterprise deployment pipelines.

The Canada KYC DQS Platform is our centralized data quality engine. It enforces strict data standards across all application flows so new accounts are compliant from creation.

The KYC Data Pipeline is an automated ETL service. It processes customer data daily from source systems into production datasets. This supports downstream compliance checks and uses parallel processing.

About the Role

As a backend engineer intern,

You will help design, build, and scale these platforms.
You will write backend code for production systems dealing with high traffic, strict regulatory rules, and large data transformations.
You will build new API features, write automated tests, and improve deployment pipelines.
You will gain hands-on experience with cloud infrastructure, ETL processes, and modern deployment practices.
You will collaborate with other engineers, product managers, and architects to deliver features. Senior team members will provide technical guidance and mentorship.

Our Tech Stacks:

Languages: Java, TypeScript, SQL, Python
Frameworks: Spring Boot, Middy (AWS Lambda middleware), Spark
Cloud: AWS (Lambda, ECS Fargate, DynamoDB, SAM, CloudWatch, SNS)
Data: DynamoDB, Snowflake
Testing: Vitest, JUnit, Cucumber (BDD), Mockito
CI/CD: Jenkins (OnePipeline/Bogie), Docker

Your Responsibilities:

Write backend code to meet story acceptance criteria.
Build and maintain high-volume APIs and ETL data pipelines.
Write automated tests and integrate them into deployment pipelines.
Participate in code reviews, design sessions, and Agile ceremonies.
Collaborate with product and engineering stakeholders to implement new system features.

Basic Qualifications:

Will obtain a Bachelor’s degree or higher from December 2026 or later.
Familiarity with backend application development and APIs.
Good communication, presentation, and writing skills.
Good understanding of testing fundamentals.
Able to work within a team setting and actively participate in team discussions.
Please include your resume and unofficial transcripts in one PDF in the attachment section under Resume/CV when you create your profile to apply.

Preferred Qualifications:

Experience with backend languages such as Java, TypeScript, or Python.
Experience with version control technology (Git).
Experience with cloud infrastructure (AWS) or CI/CD pipelines.
Experience working with databases or data pipelines.

Working at Capital One

Here you’ll uncover personal strengths, explore new interests and make an impact that matters. The work you’ll find here will keep you inspired and guide you in your career journey.

Take ownership of your own potential: As you begin your career, you’ll define your own path by gaining exposure across the business, learning new skills, and having access to tools and mentorship to understand your potential.
Find your rhythm: We believe trust fosters the flexibility and autonomy required to balance personal needs with a focus on high performance. We support a hybrid model – with 3 days in the office per week – that gives room for both collaboration and personal commitments.
A supportive community from day one: Through our robust onboarding program, orientation sessions, buddy program for new hires and early career development programs, you’ll get foundational training while building connections with your peers and leaders – cultivating a supportive community you can lean on for support and guidance.

You’ll find that Capital One is committed to helping you thrive and evolve every step of the way.

This posting is for an existing vacancy.

The expected hourly wage for this position is from $33.33 to $48.72.
