Objectives and

Responsibilities

• Build the Gateway: Design, build, scale, and maintain our stateless API gateway, serving as the highly performant front door for all Miovision applications and services.
• Architect for Scale: Keep architectural boundaries crisp by maintaining domain business logic in owning services, utilizing the platform API layer strictly for routing, access control, and formatting standards.
• Commercialize the API: Embed usage tracking, billing hooks, tenant-aware access control, and rock-solid observability into the platform from day one.
• Govern and Standardize: Partner with Architecture, Product, Security, and domain teams to enforce strict API governance, including versioning, backward compatibility, API linting, and contract testing.
• Enable AI & Automation: Design machine-readable, agent-friendly API contracts that empower our AI chatbot (Mateo), MCP servers, and future AI agents to safely discover and invoke Miovision capabilities.
• Drive Consensus: Champion cross-team alignment on complex domain modeling, resource naming, and API structures, transforming tough debates into clean, durable API contracts.
• Publish & Document: Create crystal-clear service catalog entries and developer-friendly documentation so consumers can easily discover, understand, and adopt platform capabilities.
• Code & Mentor: Roll up your sleeves to write high-quality code (primarily in Kotlin or Go), actively utilize AI-assisted development tools (like AMP), and mentor peers through deep technical design and code reviews.

The Ideal Profile: - The API Architect: You have successfully designed, deployed, and scaled a centralized API gateway within a highly complex, multi-service production environment.

• The Domain Modeler: You bring deep experience in Domain-Driven Design (DDD) and API-first methodologies (using OpenAPI), with a proven track record of driving cross-team consensus on complex data structures.
• The Platform Builder: You know how to take fragmented internal services or APIs and beautifully transform them into a cohesive, commercially ready developer platform or service catalog.
• The Code Craftsman: You boast expert-level proficiency in Kotlin, perfectly paired with extensive hands-on experience in cloud-native ecosystems including Kubernetes, Docker, and AWS.
• The Security Sentinel: You have successfully implemented and enforced robust authentication and authorization patterns at the edge, utilizing modern protocols like OIDC, OAuth 2.0, and platforms like Auth0.
• The AI Enthusiast: You demonstrate a strong understanding of—or a highly active interest in—how AI agents, LLMs, and frameworks like MCP (Model Context Protocol) interact seamlessly and securely with APIs.

Your Rewards & Well-being: We invest in our team with benefits designed for modern life and true work-life balance.

• Comprehensive Coverage: Your well-being is covered from day one with comprehensive health benefits, 24/7 virtual healthcare access, and dedicated wellness programs.
• Financial Future: Build for tomorrow with our RRSP/401K Matching Plan and share in the company's success through our Variable Incentive Plan.
• Time to Recharge: Truly unplug with our unique Mio-Days and flexible vacation policy.
• Work & Life Support: We support you with flexible work options, an internet subsidy, a remote work allowance, and enhanced leave for new parents.
