Job Description

An employer is looking for a Staff Solutions Architect to sit remote. In this role, you are the integration authority. You will own the design and improvement of our integration landscape — including our relationship with the internal platform that manages menu, cart, ordering, payment, store, and checkout backend systems, as well as our internal Golang services and the contracts between our frontend clients and the backends they depend on. You will drive architectural decisions, establish integration standards, and work hands-on to untangle the flaky, brittle integrations that are causing real pain in our mobile and web experiences. This role requires someone who can operate at both altitude and ground level — credible in a whiteboarding session with a vendor and equally comfortable reviewing a PR or pairing with an engineer on an implementation. Tasks will include:

• Own the integration architecture across customer-facing digital systems, including vendor APIs, internal Go services, and frontend/backend contracts

• Lead the design and documentation of integration standards — patterns, error handling strategies, retry logic, circuit breakers, observability hooks

• Audit existing integrations and produce actionable remediation plans; partner with product teams to execute them

• Serve as the integration design authority for new capabilities — evaluating vendor proposals, defining API contracts, and guiding implementation

• Collaborate with the restaurant-side technology organization to drive shared integration standards across both engineering orgs

• Mentor product engineers and contribute to the broader standards adoption motion led by the Enabling Team

• Partner closely with Platform Engineering on infrastructure boundaries and observability tooling

We are a company committed to creating diverse and inclusive environments where people can bring their full, authentic selves to work every day. We are an equal opportunity/affirmative action employer that believes everyone matters. Qualified candidates will receive consideration for employment regardless of their race, color, ethnicity, religion, sex (including pregnancy), sexual orientation, gender identity and expression, marital status, national origin, ancestry, genetic factors, age, disability, protected veteran status, military or uniformed service member status, or any other status or characteristic protected by applicable laws, regulations, and ordinances.
