Original job description

The bright side of mortgages

nesto is Canada’s leading digital residential mortgage lender, offering Canadians the lowest rates from the get-go - with total transparency and no haggling.

About Us

As Canada's pioneer in online mortgage lending, nesto is transforming the way Canadians finance their homes. Our mission is to offer a positive, empowering, and transparent property financing experience, simplified from start to finish.

Borrowers benefit from rates that are often lower than those offered by the big banks, along with an exceptional end-to-end mortgage experience powered by best-in-class AI technology. Fast, simple, and fully digital, nesto has been recognized as CLA Lender of the Year for three consecutive years. That's the bright side of mortgages.

Nesto Group

Nesto Group is Canada's leading provider of mortgage technology and financing solutions, with more than CAD $80 billion in residential and commercial mortgages under administration. Trusted by many of the country's leading financial institutions, we combine over 50 years of mortgage expertise with proprietary cloud and AI technology to transform the future of lending.

Powered by our proprietary cloud and AI technology, nesto has become one of Canada's fastest-growing mortgage lenders, gaining market share across direct-to-consumer (D2C) residential lending, the broker channel, and multi-family commercial lending. Recognized as one of Deloitte's Fast 50 companies for three consecutive years, we continue to push the industry forward through innovation, technology, and customer-focused solutions.

Operating through our family of brands - CMLS, nesto, and Nesto Cloud - our mission is to build Canada's mortgage ecosystem of the future and create a true Canadian champion in lending technology and financial services. Learn more at: https://nestogroup.ca/

Life at nesto

At nesto, we're passionate about challenging the status quo and building a better mortgage experience and saving money on their mortgages for Canadians. We foster a culture of collaboration, transparency, and creativity where every team member is empowered to take ownership, make an impact, and grow. If you're looking to solve meaningful problems alongside ambitious, supportive teammates, you'll feel right at home here.

About The Team

Our Data team is the backbone of Nesto Cloud, managing the flow of data that powers Canada’s most advanced mortgage platform. As a Senior Data Reliability Developer, you won't just be "checking results"; you will be a specialized engineer focused on the integrity, reliability, and scalability of our data pipelines. You will collaborate closely with Data Developers to ensure our BigQuery environments, Airflow DAGs, DBT Models, and ETL processes are bulletproof.

What You’ll Be Doing

Architect Data Quality Frameworks: Design and build robust, automated testing suites for data pipelines using Python and SQL to validate data integrity, schema consistency, and transformation logic.
Shift Left in Data: Partner with Data Developers and Product Managers during the design phase to define data contracts, quality gates, and acceptance criteria before code is even written.
Automate Everything: Develop automated "Data-SLA" monitors and observability signals (e.g., Great Expectations, Monte Carlo, or custom Python tools) to catch anomalies in BigQuery and Airflow before they hit downstream reporting.
Complex Validation: Perform deep-dive validation on complex ELT/ETL processes, ensuring high-performance datasets optimized for Power BI and internal analytics are accurate and secure.
CI/CD Integration: Implement and maintain data-specific testing within our Git-based CI/CD workflows (using Pulumi/Terraform), ensuring every deployment is backed by automated regression.
Continuous Improvement: Take ownership of broader data quality outcomes, improving documentation, data governance, and team workflows to make our development flow smoother and more reliable.

Who We’re Looking For

Experience: 5+ years of experience in Data Reliability or Data QA, with a focus on testing complex SaaS/cloud data environments.
Technical Mastery: Strong Python and SQL skills. You approach QA and reliability with a software engineering mindset, writing clean, maintainable automation code.
Modern Data Stack: Hands-on experience with GCP (BigQuery) and orchestration tools like Airflow.
Infra-as-Code: Familiarity with Pulumi or Terraform is a significant asset.
Analytical Rigor: Deep understanding of data modeling, dimensional design, and the ability to diagnose performance bottlenecks in SQL execution plans.
Startup Mindset: You are self-driven, thrive in fast-paced environments, and are comfortable with the occasional uncertainty of a hypergrowth startup.
Education: B.S. or M.S. in Computer Science, Software Engineering, or a related technical field.

Why You'll Love Working Here

We believe great people do their best work when they're supported professionally, personally, and financially. That's why we offer a comprehensive rewards package designed to help you thrive at every stage of your career.

Competitive Rewards - Competitive compensation, performance incentives (where applicable), and recognition for your contributions.
Health & Wellness - Comprehensive medical, dental, and vision coverage, Health & Wellness Spending Accounts (where applicable), telemedicine, Employee Assistance Programs, and mental health support for you and your family.
Time to Recharge - Generous vacation (4 weeks), floater days, and statutory holidays to help you recharge.
Planning for the Future - RRSP matching to support your long-term financial wellbeing.
Family Support - Enhanced maternity and parental leave top-up programs.
Learning & Growth - Education assistance, mentorship, training, and opportunities to build your career across Nesto Group.
Tools for Success - Modern technology, collaborative teams, and the resources you need to do your best work.

Diversity, Equity & Inclusion

At Nesto Group, we believe diverse perspectives make us stronger. We are committed to fostering an inclusive workplace where everyone feels respected, supported, and empowered to succeed.

We welcome applications from people of all backgrounds, including Indigenous Peoples (First Nations, Inuit, and Métis), persons with disabilities, members of racialized communities, women, and members of the 2SLGBTQIA+ community.

If you require accommodation during any stage of the recruitment process, we are committed to working with you to meet your needs.
