Full Job Description

📋 Description

• This is a high-bar individual contributor role on a team building Data APIs, custom visualisations, and AI products that sit at the core of how hoteliers understand and act on their revenue data. You’ll work across the full stack — from problem discovery with Product through to production monitoring — and you’ll bring the engineering judgment to navigate legacy code, build new systems when needed, and raise the bar for the engineers around you.
• You’ll build and ship full-stack features end-to-end — from understanding the problem with Product, breaking down PRDs into well-scoped work, thinking through edge cases before code is written, all the way through to production monitoring and support. You’ll experiment with AI-assisted workflows across the development lifecycle — from PRD to tickets to implementation — and push what’s possible with AI development tooling in a team that takes this seriously. You’ll navigate and improve legacy code with care and judgment — understanding what’s there, why it exists, and how to move it forward safely without creating downstream risk. You’ll build new systems from scratch when the problem calls for it, bringing strong systems thinking to every decision about how components fit together, how data flows, and where trade-offs matter. You’ll develop deep fluency in Duetto’s data and the hospitality domain — using that understanding to make better product and technical decisions, not just implement requirements. You’ll mentor engineers through pairing, code review, and the kind of day-to-day craft conversations that raise the bar for how the whole team works.
• Duetto is the hospitality industry’s leading revenue management platform, founded in 2012 by former Wynn Resorts executives who knew the industry needed better technology. We built the world’s first Revenue & Profit Operating System — a suite of tools (GameChanger, ScoreBoard, BlockBuster, Advance and more) that goes beyond room pricing to give hotels, resorts and casinos a complete picture of their revenue and profitability. Trusted by clients ranging from independent boutique hotels to global chains, we’ve been named the #1 Revenue Management Software by HotelTechAwards four years running and the #1 Best Place to Work in Hotel Tech in 2025. Backed by GrowthCurve Capital since 2024, we’re accelerating our investment in AI — and we’re genuinely passionate about the industry we serve. We build products we’re proud of, for customers we care about.
• You’ll develop deep fluency in Duetto’s data and the hospitality domain — using that understanding to make better product and technical decisions, not just implement requirements. You’ll mentor engineers through pairing, code review, and the kind of day-to-day craft conversations that raise the bar for how the whole team works. You’ll shape how the team works, mentor engineers, and make architectural decisions that matter. You’ll build products where the quality of the end-user experience is taken seriously — not an afterthought. You’ll work in an environment with low ego, high standards, and genuine investment in how engineers grow — the kind of environment where Staff engineers thrive.

🎯 Requirements

• Demonstrated seniority in full-stack software engineering with production experience across both backend and frontend layers
• Experience as technical lead on multiple projects that shipped to production
• Hands-on experience with AI development tools and a genuine drive to push what’s possible with them
• Strong proficiency in Java
• Frontend capability — not expected to be a specialist, but able to ship frontend work independently
• Experience building and maintaining Data APIs
• Proficiency with SQL and NoSQL databases
• Strong systems thinking — you understand how components fit together, how data flows, and where trade-offs matter
• A background in B2C products with strong UX sensibility, or substantial enterprise software experience

🏖️ Benefits

• AI-first engineering, for real. This team is actively experimenting with AI-assisted workflows across the entire development lifecycle — you won’t just be using Copilot to autocomplete, you’ll be pushing what AI-augmented development actually means in practice.
• Work that requires genuine domain depth. The Detect & Explore team builds products that help hoteliers understand and act on complex revenue data — the problems are interesting, the data is rich, and the domain rewards curiosity.
• Staff-level ownership. This is a high-autonomy IC role with real technical influence — you’ll shape how the team works, mentor engineers, and make architectural decisions that matter.
• Full-stack scope with a high UX bar. Whether your background is B2C or enterprise, you’ll be building products where the quality of the end-user experience is taken seriously — not an afterthought.
• A team that cares about craft. Low ego, high standards, and genuine investment in how engineers grow — the kind of environment where Staff engineers thrive.
