The Staff Engineer, Payments role is for a hands-on engineer who loves to build. You will spend the majority of your time in the code - using LLMs to move fast and write high-quality software - while also setting the technical direction for the payments domain. This is not an architecture or management role. We want someone who is equally comfortable whiteboarding a system design and shipping production code the same day.

You will work collaboratively in an agile environment, participating in the design, development, testing, and deployment of applications across an event-driven AWS stack. This role involves taking ownership of the payments domain, driving engineering standards, engaging in code reviews, and continuously improving development practices in alignment with OFX guidelines.

What you’ll do:

• Collaborate with other Staff engineers, tech leads and engineering managers to deliver quality code and participate in code reviews
• Use an LLM to Write efficient, maintainable code that adheres to OFX coding standards and industry best practices
• Contribute to a collaborative and inclusive team environment
• Identify and help address areas of technical debt and opportunities for refactoring
• Support agile team activities including deployments, QA, and level 3 support when needed
• Drive solution design discussions and contribute to proof-of-concept initiatives
• Communicate effectively with team members and stakeholders

What you bring 

• 10+ years of commercial software development experience - with recent, hands-on coding as a core part of your day job. If you have moved fully into architecture or management, this role is likely not the right fit.
• Demonstrated ability to operate at a system or domain level - setting technical direction while remaining deeply embedded in the codebase.
• Some fluency with LLM-assisted development - you have started experimenting with AI tooling to move faster and write better code.
• Extensive hands-on experience with TypeScript and Node.js in a production environment.
• Deep knowledge of AWS serverless and event-driven services, including Lambda, API Gateway, DynamoDB, SQS, SNS, and EventBridge.
• Experience building and deploying AWS infrastructure using CDK.
• Excellent understanding of event-driven design patterns, asynchronous messaging, and distributed systems trade-offs.
• Extensive experience with React.js, including building scalable, reusable UI components with appropriate testing
• Experience writing Architecture Decision Records, RFCs, or equivalent design documentation for a technical audience.
• A track record of cross-team influence - aligning engineers and stakeholders through written communication, design leadership, and technical credibility.
• Deep operational maturity - you think about observability, failure modes, and production behaviour before code ships.
• Experience mentoring junior engineers and demonstrably improving the capability of those around you.
• Familiarity with Agile methodologies such as TDD, Kanban, and Shift Left.
• Experience with RESTful APIs and service-oriented architecture.
• Experience with unit testing and acceptance criteria frameworks.
• Familiarity with Git and GitHub for source control.

Desirable Experience

• Experience with CI/CD pipelines and configuration management.
• Exposure to container technologies such as Docker.
• Experience working with Design Language Systems.

Please include a cover letter specifically addressing your fitness for this role. We specifically  want to understand your hands-on engineering background with nodeJs/Typescript, React and your experience with event-driven AWS systems. Generic cover letters will not be considered.
