About the job
Did you know Hopper's technology powers some of the largest travel portals in the world? Our Hopper Technology Solutions (HTS) platform drives travel purchases for major global brands — from banks to airlines to fintech leaders. This platform is a configurable, multi-tenant travel commerce engine, enabling partners to launch world-class hotel and travel booking experiences faster, with less custom engineering.
The platform is built. What comes next is growth — and that's what this team owns. We have 410M cardholders across our banking partners and we've barely scratched the surface. The work is about making partner cards genuinely more competitive: connecting cardholder behavior to the right offers at the right time, giving partners real insight into what drives incremental spend, and building the intelligence layer that compounds across the network as we scale. We're moving Commerce from a travel vendor to a strategic card partner — and the engineering work is what makes that real.
We're looking for a staff software engineer who builds great products and has figured out how to use AI to do it at a pace that wasn't possible a year ago. You're not using AI to auto-complete your code — you're orchestrating agents, building feedback loops, and shipping features end-to-end in a fraction of the time it used to take. You understand the strengths and weaknesses of LLMs, and you've developed the taste to know when to trust the output and when to intervene.
Tech stack
Backend: Scala, GCP services
Frontend: React + TypeScript
We value stack-agnostic thinking. If you've built great systems in Go, Python, Java, or anything else, and you pick things up fast — that's what matters.
Identify and execute improvements to the codebase that make it easier for both humans and AI agents to move fast and ship safely.
Work with a group of senior engineers in a low-process environment powered by trust and autonomy.
Drive decisions and consensus asynchronously with thoughtful documentation and specs.
Own features end-to-end — from the backend systems to the partner-facing surface. You'll primarily work on the backend, but expect to use AI tooling to move across the stack as needed. We care that you can ship a complete feature, not that you can write production-grade React from memory.
Architect scalable solutions and foundational patterns that let us efficiently launch new partner experiences.
Work directly with PMs and business partners to define and refine our roadmap. Your voice and technical vision matter.
Collaborate with a diverse group of people, giving and receiving feedback for growth.
A natural drive to fearlessly dive into an unknown codebase and deliver results fast.
Strong product thinking — your conception of quality and architecture is anchored in the customer experience, not in technical elegance for its own sake.
The ability to direct AI agents and automated workflows to build and maintain complex systems, and the judgment to know when to step in and when to let them run.
Experience designing the guardrails and feedback loops that keep AI-assisted development productive and reliable.
Experience with, or a mastery-level willingness to learn, distributed system development in Scala.
The ability to articulate not just how you'd solve a problem, but why, and what tradeoffs you're accepting.
Well-funded and proven startup with large ambitions, competitive salary and the upsides of pre-IPO equity packages.
Unlimited PTO.
Carrot Cash travel stipend.
Access to co-working space on demand through FlexDesk AND Work-from-home stipend.
Please ask us about our very generous parental leave, much above industry standards!.
Entrepreneurial culture where pushing limits and taking risks is everyday business.
Open communication with management and company leadership.
Small, dynamic teams = massive impact.
100% employer paid Medical, Dental and Vision coverage for employees.
Access to Disability & Life insurance.
Health Reimbursement Account (HRA).
DCA/ FSA and access to 401k plan.

Almost 30% of our app customers purchase at least one fintech product when making a booking; and consumers are 1.6x more likely to repurchase if they add fintech to their booking vs if they booked just travel.
Given the success of its fintech products, Hopper launched a B2B initiative, HTS (Hopper Technology Solutions), which represents more than 75% of the business.
Through HTS, any travel provider (airlines, hotels, banks, travel agencies, etc.) can integrate and seamlessly distribute Hopper’s fintech or travel inventory on their direct channels. As its first HTS partnership, the company partnered with Capital One to co-develop Capital One Travel, a new travel portal designed specifically for cardholders.
