Senior AI Software Engineer Visa Sponsorship Jobs in Washington DC

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 essentially a configurable, multi-tenant travel commerce engine, enabling partners to launch world-class hotel and travel booking experiences faster, with less custom engineering. We’re looking for a senior software engineer who has adopted the best practices in terms of AI-assisted coding. You are not using AI to auto-complete your code; you are using multiple agents to autonomously deliver features at a speed that was impossible a few months ago. You understand well the strengths and weaknesses of LLMs, and you know how to build a feedback loop and guardrails to get the best out of them.

Tech stack

- Our backend systems are written in Scala, and we use a suite of GCP services
- Our frontends are web apps using react + typescript

What Your Day-to-day Would Look Like

- Identify and execute improvements to the code base to allow agents to go faster and safer.
- Work with a group of top-tier engineers in a low-process environment powered by trust and high autonomy.
- Drive decisions and consensus asynchronously by leveraging AI to author the thoughtful documentation and specifications that guide the team.
- Ship fast. Learn fast. Repeat. Orchestrate AI agents to build new features from top to bottom, from UX to database, with minimal oversight.
- Architect the scalable solutions and foundational patterns that allow us to efficiently launch new portals.
- Proven experience training, deploying and iteratively optimizing LLMs to power complex product features.
- 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 the high-level feedback necessary for growth.

An ideal candidate has

- A natural drive to fearlessly deep dive into an unknown code base while keeping their eyes on the goal to deliver results fast.
- Proven ability to direct AI agents and automated workflows to architect, implement, and maintain complex software systems with minimal human intervention.
- Expertise in designing the technical guardrails and automated feedback loops that maximize the productivity and reliability of AI agents operating within the codebase.
- Strong product thinking where your conception of quality and architecture is inherently anchored in the customer experience.
- Experience with, or a mastery-level willingness to learn, distributed system development in Scala.

Perks and Benefits of working with us

- 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.

- Small, dynamic teams = massive impact.
- 100% employer paid Medical, Dental and Vision coverage for employees.

By leveraging massive amounts of data and advanced machine learning algorithms, Hopper combines its world-class travel agency offering with proprietary fintech products to bring transparency, flexibility and savings to travelers globally. We have developed several unique fintech solutions that address everything from pricing volatility to trip disruptions – helping people travel better and save more on their trips. The Hopper platform serves hundreds of millions of travelers globally and continues to capture market share around the world. The Hopper app has been downloaded over 120 million times and has become largely popular among younger travelers – with 70% of its users being Gen Z and millennials.

In recent years, we’ve grown into a travel fintech provider, commerce platform, and global travel agency that powers some of the world’s largest brands. Through HTS, our B2B division, the company supercharges its partners’ direct channels by integrating our fintech products on their sites or powering end-to-end travel portals.

- 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.
