• Design, develop, and maintain the filesystem and container runtime components of Docker's local runtime stack. • Investigate and resolve correctness, performance, and stability issues in the filesystem layer across macOS, Windows, and Linux. • Work on VirtioFS, OverlayFS, and related filesystem technologies to improve performance and reliability for AI agent workloads. • Contribute to containerd integration and OCI-compliant container lifecycle management. • Collaborate with peers on the team to evolve the architecture of the runtime as requirements grow. • Engage with the open source community on filesystem and container runtime related projects. • Participate in on-call rotations and respond to critical stability issues affecting users. • Document your work clearly and share knowledge with the rest of the team.

• Contribute to the development of new features based on clearly defined tasks and requirements • Work on real product challenges and help shape solutions that deliver tangible value to customers • Build a deep understanding of system architecture and business domain • Make sound technical decisions in daily work • Follow architectural guidelines and take responsibility for writing high-quality unit and integration tests • Ensure the stability, reliability, and long-term maintainability of software • Uphold best practices across SQL databases, web services, CI/CD pipelines, and message-driven systems • Collaborate closely with cross-functional teams, including product, QA, and other developers • Translate new ideas and requirements into practical, well-designed technical solutions • Support performance improvements, identify technical weaknesses, and contribute to testing efforts

• Provide technical leadership for systems supporting Canadian payment rails including Interac e-Transfer®, Interac Debit, EFT (ACSS), Real-Time Rail (RTR), and cheque imaging, in alignment with Payments Canada rules and standards • Lead design decisions that ensure high availability, low latency, resiliency, and scalability for member-facing and back-office payment services • Own technical oversight for payment processing flows including initiation, validation, clearing, settlement, reconciliation, returns, reversals, and exception handling • Partner closely with Payment Product and Payment Operations to understand business goals, regulatory drivers, and operational pain points, and to jointly define technology solutions that meet business needs and requirements • Translate product concepts, operational needs, and regulatory requirements into clear technical options, solution designs, and delivery approaches • Act as a trusted advisor to Product and Operations, providing input on feasibility, trade‑offs, risk, cost, and long‑term implications of technology decisions • Support the evolution of payment products and services by identifying technology opportunities that improve member experience, operational efficiency, and resilience • Lead integrations with Payments Canada–operated systems (ACSS, Lynx, RTR), Interac services, and external payment gateways • Drive adoption and coexistence strategies for ISO 20022 messaging, supporting migration, translation, and backward compatibility across payment ecosystems • Modernize legacy payment services to support 24x7 operations, improved observability, and future payment innovation while reducing technical debt • Lead and continuously improve CI/CD pipelines for payment platforms, enabling frequent, low-risk deployments while maintaining strict security and compliance standards • Ensure strong alignment with DevSecOps principles, including secure coding, automated testing, vulnerability management, and audit readiness • Champion system observability, including monitoring, alerting, logging, and performance metrics, with appropriate handling of sensitive and regulated data • Partner closely with Payment Operations, Risk, Fraud, and Compliance teams to ensure payment platforms support AML/ATF controls, fraud detection, real-time monitoring, and regulatory reporting requirements • Provide technical leadership and mentorship to software developers, systems analysts, and QA analysts, promoting best practices in secure coding, performance optimization, and resilient design • Collaborate with Agile Delivery Leads, Partners, Vendors to ensure payment platform priorities, technical health, and operational risks are effectively represented and prioritized in the backlog • Act as a senior technical escalation point for complex payment issues, incidents, and architectural decisions • Maintain strong Vendor relationships focused on supporting Servus’s needs within the broader payment ecosystem

• Own the customer-facing product surface • Lead ambiguous, cross-functional product initiatives from vague customer need through scoped • Own the full product lifecycle — API design, backend behavior, error states, docs, and the customer conversation when something goes wrong • Define product specs independently, validate with team and customers, and drive to implementation without requiring PM handoff • Balance shipping velocity with the correctness and reliability required for financial systems handling real customer funds • Collaborate with customers directly to surface friction points and translate them into clearer APIs, better docs, or self-serve product surfaces
