Python Developer

Sr Software Engineer (Backend)

Toronto, ON

Fulltime

Primary Responsibilities

Engineering and Architecture

• Design, build, and maintain backend financial and payments system flows (e.g., core banking, ACH, wire, card, and digital asset transaction processing).

• Influence software architecture and lead design decisions for the Platform, with particular focus on payments and money-movement systems.

• Develop, test, and launch new features and releases for the Platform.

• Document processes and key data flows

• Ensure compliance with regulatory requirements and support audit certification efforts, including documenting systems for regulatory and internal audit purposes.

Product & Requirements Enablement

• Partner with engineering, product, operations, and compliance teams to translate business needs into clear, actionable technical requirements and specifications.

• Organize and decompose business requirements into well-structured functional and technical specs that other engineers can execute against.

• Act as a bridge between business stakeholders and the engineering team, clarifying scope, surfacing technical trade-offs, and reducing ambiguity before development begins.

• Document and improve engineering processes, workflows, and SDLC practices to increase team efficiency and knowledge sharing.

Leadership & Team Enablement

• Set technical direction and best practices that enable other engineers to deliver high-quality work independently.

• Influence and align cross-functional partners and engineering peers without relying on formal authority or direct reports.

• As needed mentor engineers on logic, code quality, and requirements-writing practices.

• Make independent, sound decisions on system design and process improvements within defined parameters.

Skills and Experience

• Minimum of 5 years of experience in software engineering, including designing, building, deploying, scaling, and maintaining modern, cloud-based production services, with knowledge of service-oriented architecture.

• Proven experience designing and building backend financial or payments system flows (e.g., APIs workflows supporting core banking, payment rails, ledgers, settlement, or digital asset transaction processing).

• Proficiency writing high-quality, well-tested code using one or more languages (e.g., Python, Next.js, React, Golang, C#), building APIs, and building/using databases (e.g., Postgres, DynamoDB).

• Demonstrated ability to gather and translate business requirements into technical specifications

• Strong written and verbal communication skills, with the ability to create clear, detailed technical and functional documentation.

• Leadership and influencing skills — comfortable guiding and developing other engineers and driving alignment across teams without formal direct-report authority.

• Self-directed work style with the ability to manage multiple priorities and make sound independent decisions.

• Creativity, organization, and troubleshooting skills.

• Experience with Blockchain technology (e.g., Bitcoin, Ethereum) or crypto-forward experience, including familiarity with onchain activity and dApps or blockchain-based services is a nice to have.
