The Opportunity

A fast-scaling NYC consumer-tech startup with serious momentum. Real traction, real users, real revenue, and the kind of pace that only comes from a team that ships.

You’ll sit at the sharp end of the product as the go-to technical fixer for their customers, resolving live issues across payments, integrations, and product. Think fast triage, real fixes, and shipping code, not ticket-shuffling. You’ll free the core engineering team to keep building while you own the customer experience end to end.

The twist: this isn’t just support. You’ll build and refine AI agent workflows that scale how the company handles support over time, with room to grow into front-end product work. Direct line to the founders. No layers. No politics.

What you’ll be doing

• Living in customer Slack and support tooling, resolving bugs in real time (high volume, fast turnaround)
• Debugging and shipping fixes across payments, integrations, and product
• Acting as the technical point of contact for customer-facing and sales teams
• Jumping on client calls to troubleshoot and deliver a great experience
• Spotting patterns and building AI agent workflows to kill repeat issues at the source

What you’ll bring

• A degree or strong background in a technical field (CS, engineering, data, or similar); technical bootcamp grads with a technical undergrad also considered
• Comfort shipping production PRs without breaking things
• High agency and resourcefulness (you dig into problems, you don’t escalate blind)
• Strong communicator, calm on client calls and in fast Slack environments
• Genuine interest in customer-facing work, not just pure engineering

Nice to have

• Front-end implementation skills (able to take work fully end to end)
• Background in forward-deployed / field engineering or solutions engineering
• Experience at an early-stage startup (seed to Series B)

Tight team, big traction, founder access from day one. If you’re a builder who loves solving real customer problems fast, get in touch for a quick response.
