Software Engineer - All Levels

GlossGenius is the AI-powered system behind the world’s most meaningful appointments, helping 100,000+ service businesses earn more revenue and free up time for the work they love. Our agentic workforce gets more clients in the door, grows profit per appointment, and keeps clients coming back — doing the jobs owners never had time for and couldn’t justify hiring to fill. Businesses on GlossGenius process billions in annual payment volume, and see 65% more revenue using GlossGenius Payments by growing ticket size, rebooking clients at checkout, and saving on processing fees.

GlossGenius is building an agentic workforce: AI systems that act on behalf of appointment-based business owners, not just assist them. The engineers who join now will be the ones who architect it. We're hiring across two paths: product engineers who work at the intersection of AI capabilities and customer problems, shipping the features that put agentic tools directly in front of the businesses we serve; and platform engineers who build the scalable, reliable infrastructure that makes those AI products possible in the first place. Whichever path you're on, the expectation is the same: you build with AI as the default layer underneath how you work, not a tool you reach for occasionally.

You must be commutable to our NYC headquarters and will operate in a hybrid environment. We default to being in-office 3–4 days per week with required attendance on Tuesdays and Thursdays.

We're open to engineers with different language backgrounds who are excited to grow. Our current stack:

• Kotlin (Micronaut, jOOQ), gRPC, protobuf
• TypeScript / JavaScript (React, Redux)
• React Native
• AWS, Kubernetes, Postgres, Terraform
• Linear

• →Architect and ship AI-powered features that change how service businesses operate: not wrappers around existing tools, but net-new capabilities that weren't possible before
• →Build and maintain large-scale systems that process billions in payments and serve 120,000+ businesses, with reliability and performance as non-negotiables
• →Use AI to architect, debug, write, and review code, and hold a higher bar for your own output because of it
• →Own your work end to end: from technical design through production, with full accountability for what you ship and how it performs
• →Build the platform infrastructure that lets product teams move faster: scalable, extensible systems that remove friction rather than create it
• →Challenge how we build: when you see a faster path or a better architecture, you're expected to make the case and drive it

• 2+ years of professional software engineering experience, with demonstrated ownership of production systems, not just contributions to a team that owned them
• You use AI to architect, debug, write, and review code, and you've shipped AI-powered features or systems, not just used AI-assisted editors
• Move fast and make decisions: you don't wait for a fully scoped ticket to start thinking, you'd rather ship something real and iterate than spend weeks perfecting a plan
• Strong analytical instincts for efficiency, scalability, and system reliability, you think about what breaks at scale before it breaks in production
• Entrepreneurial ownership mindset, you treat the problems you're assigned as yours to solve, not tasks to complete
• Collaborative by default, you make the engineers around you better, not just the code you personally write
