Senior Software Engineer - Customer Experience Platform

Hopper • Toronto, ON

1d • CA$150,000 - CA$250,000 • Remote

About The Position

As a Software Engineer on the CX Platform team, you will design, build, and evolve the core systems behind Hopper’s post-booking experience. Your work will directly impact customers, internal support agents, and the continued expansion of HTS Assist across AI-driven voice and chat. You’ll collaborate closely with Product, Design, AI, Data, and Operations partners to deliver intelligent, scalable customer service systems, including conversational AI workflows, self-service customer journeys, internal tools used by thousands of agents, and infrastructure that enables partner-specific experiences. You’ll report to a Senior Engineering Manager and work alongside engineers focused on platform services, integrations, AI orchestration, and self-service UX.

Requirements

• 6+ years of software engineering experience building large-scale distributed systems or customer-facing applications
• Strong command of both modern frontend and backend development, with the ability to contribute meaningfully across the full stack
• Hands-on experience designing and maintaining RESTful APIs, microservices, or event-driven systems
• Comfort with data storage and cloud infrastructure at a senior level — you know how to make the right tradeoffs without needing to be told
• A product engineer mindset: you think about the user experience, ask why before how, and take ownership of outcomes, not just outputs
• Strong communication skills and a track record of effective cross-functional collaboration with distributed teams

Nice To Haves

• Experience with conversational AI, LLM orchestration, or automation systems
• Experience building customer service, CRM, telephony, contact center, or workflow automation tools
• Familiarity with Scala/Python, React, TypeScript, or modern frontend frameworks for engineers who want to contribute full-stack
• Experience integrating with external systems (e.g., telephony APIs, identity providers, payment gateways, CRMs)
• Knowledge of travel industry technologies (PSS/GDS, hotel PMS/CRS) is a plus, though not required

Responsibilities

• Design, build, and improve the backend and full-stack systems that power HTS Assist, internal agent tools, and customer self-serve flows
• Develop scalable APIs, microservices, and orchestration logic supporting complex post-booking journeys across AI, chat, voice, and web
• Partner with Product, Design, AI, and Operations to deliver features that streamline customer experiences and improve agent efficiency
• Integrate with external systems — telephony, CRM, identity, booking platforms — to support internal use cases and partner deployments
• Own features end-to-end, from technical design through implementation, testing, deployment, monitoring, and iteration
• Contribute to architectural decisions, code reviews, and reliability improvements that raise the bar for the broader team
• Analyse system performance and user behaviour to identify opportunities for automation, optimisation, and cost reduction
