About the role

About the Role HTS Assist is Hopper's agentic AI assistant for travel, resolving flight changes, cancellations, refunds, and bookings over chat and voice for some of the world's largest travel brands. We're looking for a senior full stack engineer to anchor this product, owning the realtime and voice layer end to end while building across React/TypeScript front ends, Scala and Python services, and cloud infrastructure. The team is lean and senior, ownership is broad, and the path from your code to a traveler's phone call is short.

What would your day-to-day look like

Own the voice channel end to end, including telephony and CPaaS integrations (e.g., Twilio, Amazon Connect), streaming speech-to-text and text-to-speech pipelines, realtime model orchestration, and latency and quality budgets

Build product features across the stack, including web chat front ends in React/TypeScript, backend services in Scala and Python, and infrastructure on GCP

Design for multi-tenant scale, with one codebase serving many partners through configuration rather than forks

Build the safety and compliance plumbing enterprise partners audit, including guardrails, content filtering, and PII redaction integration points

Keep revenue-critical deployments healthy through observability, alerting, incident response, and SLA performance

Build the platform capabilities forward-deployed engineers configure for partner telephony integrations and go-lives

Raise the engineering bar through code review, architecture reviews, and mentoring

An ideal candidate has

6+ years of software engineering experience, with senior-level ownership of production systems and genuine full-stack range

Hands-on realtime systems experience, such as voice applications, WebRTC/SIP, streaming media, or comparable low-latency products

Strength in a modern front end (React, TypeScript) and depth on the backend (Scala or another JVM language, and/or Python), along with cloud infrastructure experience on GCP or AWS

A track record designing, building, and maintaining RESTful APIs, microservices, or event-driven systems

Familiarity using AI coding tools as a standard part of their workflow, with the judgment to review, correct, and own everything that ships

An operable-systems mindset, covering SLAs, observability, on-call rotations, and rollback plans

The ability to break down complex problems, make pragmatic tradeoffs, and ship iteratively, backed by strong communication across product, design, and operations

Bonus points for conversational AI or LLM orchestration experience, including speech technologies such as Deepgram, ElevenLabs, Whisper, or OpenAI Realtime

Bonus points for working knowledge of cloud telephony or CPaaS platforms such as Twilio, Amazon Connect, Genesys, or LiveKit

Bonus points for experience building customer service, CRM, contact center, or workflow automation tools

Familiarity with travel industry technologies (PSS/GDS, hotel PMS/CRS) is a plus, though not required
