Senior Full Stack Engineer Jobs in Milton, ON (NOW HIRING)

Flinks is the embedded finance platform that brings together connectivity, intelligence, and payments — giving businesses the infrastructure they need to build and deliver seamless financial experiences at scale.

As a leader in Open Finance in Canada, we’ve grown since 2016 into one of North America’s most trusted platforms for financial data access, enrichment, and money movement. We work with innovators across many industries, including lending, fintech, banking, insurance, and wealth management.

Today, our platform connects to 15,000+ financial institutions across North America and powers over 1M monthly connections. We also give our customers unprecedented visibility into 4,500+ real-time financial insights to support smarter decisioning. Companies rely on Flinks to streamline onboarding, verify income, assess credit risk, and power faster payment experiences.

We’re on a mission to drive financial innovation and help businesses build financial experiences that feel effortless, connected, and customer-first. That’s where you come in.

We're hiring Senior Full-Stack Developers to build and own the client-facing product experiences at Flinks. You'll work across the Angular/TypeScript front end and the C#/.NET back end, owning features end to end - from the interface a client touches to the API that powers it.

This is a true full-stack role - we're looking for real depth on both sides of the stack. The exact balance depends on the team you join: some of our product areas lean more front-end, others more back-end and we'll work out the best fit with you during the process. Flinks teams span Connect (bank-data aggregation), Pay (money movement), Enrich / Attributes (transaction enrichment), Upload (document processing), the client dashboard and Outbound (open banking) - so there's a surface to match most strengths.

We're not building software for software's sake. Our products only matter when a client can see, trust and act on what we ship - so this role is judged by the business outcomes your work moves: client adoption, faster integration and time-to-value, fewer support escalations, data clients can rely on. If you like owning a product surface from the component down to the API that feeds it, this is built for you.

• Own product features end to end - design, build, test, deploy, and support features across both the Angular front end and the C#/.NET back end, taking responsibility for the complete user experience.
• Build exceptional client experiences - create performant, accessible, and intuitive interfaces that help customers confidently work with complex financial data, from dashboards and visualizations to onboarding and transaction workflows.
• Design and evolve APIs - build reliable, well-documented REST APIs and data contracts that are secure, scalable, backwards compatible, and easy for internal and external consumers to integrate with.
• Write production-quality software - contribute clean, maintainable, well-tested code while continuously improving architecture, performance, reliability, and operational excellence.
• Collaborate across disciplines - partner closely with Product Managers, Product Designers, QA, Data Science, and fellow engineers to translate business problems into technical solutions that deliver measurable customer value.
• Own production outcomes - monitor, troubleshoot, and improve the systems you build using observability tools, testing, and continuous delivery practices to ensure a reliable customer experience.
• Raise the engineering bar - provide thoughtful code reviews, mentor other developers, share technical knowledge, and help improve engineering standards across the team.
• Leverage AI as a force multiplier - use AI-assisted development to accelerate implementation while applying sound engineering judgment, thoughtful system design, and strong problem framing to deliver the right solutions.

Where you land depends on the team, but the kind of work spans Flinks' product surfaces:

• Client-facing dashboards - the Angular apps where clients explore transactions, enrichment insights and attributes and export the data they run on.
• Connect - the aggregation and connectivity flows that link financial institutions and bring data in.
• Pay - money-movement experiences and the services behind them.
• Enrich / Attributes - turning categorized and enriched data into the contracts and views clients consume.
• Upload - the document-processing flow and the experience around it.
• Outbound - open-banking client integration surfaces.

• Front-end: Angular, TypeScript, RxJS, NgRx, Angular Material, Tailwind CSS
• Back-end: C#/.NET 8+, REST APIs, Entity Framework Core
• Data: PostgreSQL, SQL Server, Redis, Firestore
• Cloud & Infrastructure: Google Cloud Platform, Kubernetes, Docker, Terraform, Pub/Sub
• Developer Tools: Azure DevOps, Git, Webpack
• Testing & Observability: Cypress, Playwright, Grafana

You don't need experience with every technology listed above. Strong software engineering fundamentals matter more than familiarity with our exact stack. The non-negotiables are production experience with Angular, TypeScript, and C#/.NET, along with the ability to build and own features across the full application stack.

At Flinks, full-stack engineers don't simply implement tickets—they own customer outcomes.

You'll build software that powers financial experiences used by hundreds of businesses and millions of financial account connections every month. Your work will directly influence how customers onboard, integrate, move money, and make financial decisions.

What you'll enjoy about this role:

• End-to-end ownership across the entire application stack—from Angular components to .NET APIs and production deployment.
• Meaningful product impact, where success is measured by customer adoption, reliability, usability, and business outcomes—not lines of code.
• Modern engineering environment built on Angular, .NET, Kubernetes, Google Cloud Platform, and AI-assisted development practices.
• Collaborative engineering culture that values ownership, curiosity, pragmatic decision-making, and continuous improvement.
• Opportunities to grow across multiple product domains while helping shape the future of Open Finance in Canada.

• Experience: 6-8+ years building and shipping production full-stack web applications, with strong Angular/TypeScript front-end depth and hands-on C#/.NET API experience.
• Education: Bachelor's degree in Computer Science, Software Engineering or a related technical field, or equivalent practical experience.
• Non-Negotiables: production-grade Angular with TypeScript and working C#/.NET on a relational database - you can own a feature across the front-end and the API. A front-end-only or back-end-only profile won't meet the fullstack bar.
• Work authorization: must be legally authorized to work in Canada.

For experienced and qualified hires located in Canada, of senior (IC4) level, the compensation range is between $120,000 to $160,000 CAD annually.

As part of the total rewards package, Flinks offers:

• Health & Dental coverage as of Day 1
• Flexible Paid Time Off (FTO)
• Remote work environment with frequent in-person gatherings and activities.
• Career development, learning opportunities and growth
• And more

We are committed to providing accommodations for persons with disabilities. If you require accommodation, we will work with you to meet your needs.
