Backend / Platform Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Backend / Platform Engineer based in Canada . As a Backend / Platform Engineer, you will play a key role in designing and developing the core services powering an enterprise AI platform. You will contribute to building scalable backend infrastructure, APIs, orchestration systems, and platform capabilities that support both internal product teams and external customers. Working in a collaborative, remote-first engineering environment, you will take ownership of services throughout their entire lifecycle, from architecture and implementation to deployment and ongoing support. You will tackle complex distributed systems challenges while ensuring reliability, security, and performance. This is an opportunity to shape innovative AI-driven solutions and build robust platform technologies at enterprise scale. Accountabilities: - Design, develop, and operate core backend services supporting an enterprise AI platform, including AI gateways, orchestration layers, APIs, and platform infrastructure. - Build and maintain platform capabilities such as entitlements, tenancy models, usage metering, quotas, and governed data access. - Develop scalable APIs and intuitive developer experiences for internal engineering teams and external customers. - Design and implement multi-tenant architectures, ensuring appropriate tenant isolation, service boundaries, and platform-level security controls. - Build integration frameworks, connector patterns, and reliable data access mechanisms to support diverse enterprise systems. - Ensure system resilience by addressing distributed systems challenges, including retries, partial failures, consistency, idempotency, and back-pressure. - Take end-to-end ownership of backend services, covering architecture, development, testing, deployment, monitoring, reliability, and production support. - Collaborate with cross-functional stakeholders to translate technical and business requirements into effective platform solutions.

- Continuously improve engineering practices, system performance, and operational reliability while balancing delivery speed and technical quality. Requirements: - Proven experience developing and operating production backend systems, APIs, or distributed platform services. - Strong software engineering fundamentals, with the ability to design reliable, scalable, testable, and maintainable applications. - Experience with platform capabilities such as AI gateways, orchestration systems, entitlements, tenancy, metering, or usage quotas. - Solid understanding of API design, developer experience, multi-tenant architectures, and service isolation. - Experience building integration frameworks, connector solutions, event-driven systems, or governed data access patterns. - Strong knowledge of distributed systems concepts, including retries, consistency, idempotency, back-pressure, and failure management. - Experience managing services throughout their complete lifecycle, from initial design to production deployment and ongoing maintenance. - Proficiency in one or more backend programming languages, particularly C#, Python, or Go. - Familiarity with API gateways, orchestration platforms, event-driven architectures, and platform engineering principles. - Understanding of AI technologies and architectures, including LLMs, RAG, agentic workflows, tool/function calling, MCP, and A2A. - Knowledge of event-sourced metering, billing-related services, quotas, and entitlement management is an advantage. - Experience developing enterprise-scale software used across multiple products, customers, or internal teams. - Familiarity with AI-assisted development tools, combined with strong code review, testing, and architectural discipline.
