Job Description
Senior Agentic AI Software Engineer (100% Remote)
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.
- 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.
- Carrot Cash travel stipend.
- Hopper will cover 100% of the employee premiums for EOR-offered health, dental, life and short term disability insurances with SulAmerica.
- Hopper offers employees in Brazil monthly meal vouchers
- Very generous parental leave
- Flexdesk All Access Pass & Work-from-home stipend.
- Entrepreneurial culture where pushing limits and taking risks is everyday business.
- Open communication with management and company leadership.
- Small, dynamic teams = massive impact.
