Senior Full Stack Engineer (Realtime & Voice) Customer Experience Platform

About This Opportunity

We are representing a confidential travel technology client seeking a Senior Full Stack Engineer to anchor their agentic AI assistant platform. This platform handles flight changes, cancellations, refunds, and bookings over chat and voice for major travel brands. You'll own the realtime and voice layer end to end, building across React/TypeScript front ends, Scala and Python services, and cloud infrastructure. The team is lean and senior, ownership is broad, and impact is immediate.

Responsibilities

• 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

What We're Looking For

• 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
• Track record designing, building, and maintaining RESTful APIs, microservices, or event-driven systems
• Familiarity using AI coding tools as a standard part of your workflow, with the judgment to review, correct, and own everything that ships
• Operable-systems mindset, covering SLAs, observability, on-call rotations, and rollback plans
• Ability to break down complex problems, make pragmatic tradeoffs, and ship iteratively, backed by strong communication across product, design, and operations
• Bonus: Conversational AI or LLM orchestration experience, including speech technologies such as Deepgram, ElevenLabs, Whisper, or OpenAI Realtime
• Bonus: Working knowledge of cloud telephony or CPaaS platforms such as Twilio, Amazon Connect, Genesys, or LiveKit
• Bonus: Experience building customer service, CRM, contact center, or workflow automation tools
• Bonus: Familiarity with travel industry technologies (PSS/GDS, hotel PMS/CRS)
