Senior Backend Software Engineer - AI-Powered Marketing Platform

About the Role

We're hiring a Senior Backend Software Engineer to join our profitable, fast-scaling AI platform. This Senior Backend Software Engineer remote position offers a unique opportunity to work on systems that have already processed over half a billion dollars in online orders, impacting 1 in 5 Americans who have used our customer-facing websites. Our mission is to empower local restaurants with the same AI-powered marketing engine that big chains utilize, providing automated SEO, online ordering, loyalty programs, and email/SMS campaigns, all managed by experts.

As a Senior Backend Software Engineer remote, you will be part of a small, intentional engineering team of about 60 engineers. You will own the guest lifecycle and loyalty platform, building high-volume, multi-channel marketing infrastructures that convert first-time guests into regular customers. If you have experience building systems that operate at scale and are looking to do meaningful work, this role is for you.

What You'll Do

• Own the email, SMS, and push notification infrastructure that powers high-volume, multi-channel campaigns for thousands of restaurant customers.
• Build and operate guest journey automation and loyalty systems integration end-to-end, focusing on deliverability, performance, and reliability at scale.
• Architect and maintain campaign orchestration pipelines using modern tooling including Temporal workflows and Kafka.
• Collaborate directly with customers and C-suite stakeholders, ensuring effective communication at all levels of the organization.
• Drive architectural decisions, contribute to roadmapping, and mentor team members.
• Thrive in ambiguity, defining your work as much as executing it.

Why This Seat

This is a profitable company with real revenue and customers. You will be building production systems that affect millions of people, not just internal tooling. With a 60-person engineering organization, your work will be visible, your voice will matter, and your impact will be measurable. There is a quick path to Staff Engineer, as the team promotes quickly and rewards ownership, not tenure. This position is remote-first with flexibility, and there is an optional San Francisco office for those who prefer in-person collaboration.

You'll Thrive Here If You Have

• 5+ years of experience building and operating backend systems in production at scale, with a focus on operational complexity.
• Experience in hyper-growth, consumer-facing environments, handling real user volume across mobile or web.
• A background in high-growth startups or top-tier tech companies, with a trajectory of promotions and high ownership.
• Proficiency in TypeScript and Node.js, comfortable in a modern async/event-driven backend stack.
• Exceptional communication skills with engineers, product teams, and non-technical stakeholders.
• A passion for ambiguity and ownership, thriving in a fast-paced environment.

Nice-to-Haves

• Experience specifically in e-commerce, loyalty programs, or marketing automation systems.
• Familiarity with Temporal workflows, Kafka, or similar infrastructure for distributed job orchestration.
• A background at a company that has navigated the scaling inflection point (e.g., Series B to Series D).
• A CS degree from a top program.

What We Offer

• Competitive base salary plus equity.
• Fully remote work from anywhere in the U.S. or Canada.
• Direct exposure to customers and leadership with a short feedback loop.
• A fast-moving, low-overhead culture where seniors act like owners.
• Optional in-person collaboration at our San Francisco HQ.

Must-Haves (Logistics)

• Based in the United States or Canada (excluding Quebec).
• H1B transfers supported; no additional visa sponsorship beyond that.
