• Develop and maintain web applications using backend technologies. • Lead and take ownership of the project end to end. • Build responsive front-end user interface with JavaScript/React. • Write complex SQL and manage relational databases, including data migrations. • Design and develop APIs as part of application frameworks. • Implement and integrate Elasticsearch into existing applications. • Build cloud-native applications in AWS.

• Assist in developing and maintaining applications using .NET technologies • Develop basic UI components using JavaScript, HTML, and CSS • Fix defects, perform unit testing, and support QA activities • Collaborate with senior developers and follow coding standards • Participate in learning and upskilling on enterprise technologies

• Design, build, and maintain high-quality software systems and services • Work on a variety of technologies, frameworks, and platforms, adapting quickly as project needs evolve • Solve complex technical and logical problems with efficient and well-structured solutions • Leverage AI-powered development tools to accelerate development, debugging, research, and documentation • Collaborate with engineers, architects, and product stakeholders to deliver reliable solutions • Participate in code reviews, testing, and performance improvements • Continuously learn and experiment with new programming languages, frameworks, and technologies • Contribute ideas that improve engineering productivity, automation, and innovation.

• Own core ledger infrastructure: design, build, and evolve the systems that record financial transactions accurately and durably, using Java/Kotlin in a microservices architecture. • Model financial correctness by translating double-entry bookkeeping principles and accounting logic into clean, testable, auditable code that Finance and Compliance can trust. • Handle high-throughput transaction processing and design systems that maintain strong consistency guarantees under load without sacrificing performance. • Drive audit trails and compliance reporting so every transaction is traceable, every state change is logged, and every report is reproducible. • Collaborate broadly across Wealthsimple — partnering with product teams to ensure their transactions are properly recorded, and supporting Finance, Accounting, Audit, Brokerage Operations, and Customer Service with the tooling and data they need to do their jobs. • Contribute to the roadmap by bringing your domain expertise to planning conversations. You'll have meaningful input on what gets built and why, not just how. • Define what "correct" looks like for ledger systems, and build the observability, alerting, and reconciliation tooling to prove it continuously.
