Restaurant
365 is a SaaS company disrupting the restaurant industry! Our cloud-based platform provides a unique, centralized solution for accounting and back-office operations for restaurants. Restaurant
365’s culture is focused on empowering team members to produce top‑notch results while elevating their skills. We’re constantly evolving and improving to make sure we are and always will be “Best in Class” … and we want that for you too!

You will be a senior technical leader responsible for the core platform architecture that underpins R365’s products. You’ll drive the design for shared platform services (identity, permissions, workflow, integrations, data foundations, and core application capabilities), ensuring they are secure, scalable, and reusable across product lines. In addition to platform decomposition and modernization, you will guide the organization toward a scalable marketplace ecosystem that enables partners, developers, and product teams to safely extend and innovate on the platform through well‑defined APIs, events, and extension models.

This role combines deep hands‑on architectural expertise with cross‑functional leadership, driving technical standards that enable teams to deliver faster with higher quality.

• Own and evolve the end‑to‑end architecture for core Platform services, including identity, permissions, workflow, integration, and shared domain capabilities.
• Define clear service boundaries, contracts, and patterns that enable modularity, reusability, and safe change across the platform.
• Shape and advance the platform’s marketplace and extensibility architecture, including API exposure patterns, eventing, and webhook models, app/extension sandboxing, and partner integration approaches that allow third parties and internal teams to build safely on top of R365.
• Lead platform‑focused architecture reviews and technical governance, ensuring consistency with enterprise architecture and long‑term strategy.
• Partner with Product, Engineering, Infrastructure, and Security to embed platform‑first and marketplace‑ready thinking into roadmaps and execution plans, aligning platform investments with ecosystem and extensibility goals.
• Drive modernization of legacy components into well‑defined platform services and extension points, aligning teams on migration strategies, sequencing, and success criteria.
• Establish and maintain reference architectures, patterns, and frameworks (including marketplace and integration blueprints) that product teams can adopt to build on the platform efficiently.
• Anticipate platform‑level risks (scalability, reliability, performance, security, data integrity, and ecosystem complexity) and design long‑term solutions that prevent systemic issues.
• Mentor architects and principal engineers across product lines, raising architectural maturity and promoting shared platform and marketplace patterns and practices.
• Provide deep architectural guidance on complex cross‑team initiatives, acting as a key decision‑maker for platform and marketplace‑related tradeoffs.
• Represent the Platform architecture in cross‑functional forums, translating technical direction—especially around extensibility and ecosystem growth—into clear business value and outcomes.
• Contribute to external technical communities as a platform subject‑matter expert, reinforcing R365’s position as a leading, extensible SaaS platform provider.

• BS/MS in Computer Science or equivalent professional experience.
• 14+ years of engineering experience, including significant experience with large‑scale, distributed systems and platform architecture.
• Proven leadership in architecture, standards, and cross‑functional collaboration across multiple teams and domains.
• Recognized expertise in multiple domains such as identity and access management, permissions models, workflow/orchestration, integrations/APIs, and data‑intensive services.
• Demonstrated success leading modernization and decomposition efforts (e.g., from monolith to modular or service‑oriented/platform architectures).
• Experienced designing or evolving extensible platforms…
