About Fly Fairly

Fly Fairly is one of Southeast Asia’s fastest-growing travel tech startups, reimagining how the world books flights. Headquartered in Singapore, we’re backed by a team that’s built at eBay, Agoda, Booking.com, ShopBack, and Hoolah.

We’re not your typical OTA. We’re building a modern consumer platform that blends flexible payments (like BNPL and crypto), agentic AI, and deep personalization across the travel lifecycle — from flight discovery to price tracking, carbon scoring, and smart redemptions.

With our platform live on flyfairly.com and rapid expansion into the US, UK, and Middle East, we’re looking for sharp engineers who understand how the flight booking world really works — and want to make it better.

Why This Role Exists

We’re not just looking for a developer. We’re looking for an engineer with solid experience in building and maintaining OTA flight booking systems. You’ll sit at the intersection of product, engineering, and airline data, helping us build a resilient, high-performance flight engine that can scale globally.

Your mission?

⚙️ Design and own the systems that power our shopping, pricing, and booking workflows.

💡 Solve messy problems across flight caching, ancillaries, fare rule s, and payments.

🌍 Bring deep OTA experience to a team that moves fast and builds for real travelers.

What You’ll Do

🛫 Build the engine: Own and evolve our flight search and booking platform using Node.js and Typescript across the stack.

📦 Integrate deeply: Work with flight data sources (GDS/NDC/aggregators) and build resilient API layers for real-time and cached results.

🧾 Handle complexity: Implement logic for fare validation, SSRs, ancillaries, refundability, and price surcharges.

📊 Optimize performance: Monitor flight engine speed, caching strategies, and look-to-book performance.

🔐 Ensure reliability: Own uptime, observability, and error monitoring for mission-critical APIs.

💳 Connect the checkout: Collaborate with our payments team to handle BNPL, crypto, and multiple currencies.

🧠 Bring OTA context: Help us avoid reinventing broken wheels and apply proven best practices from your experience.

📈 Shape the roadmap: Work directly with product and growth teams to prioritize features that improve booking conversion and retention.

Who You Are

🌏 You’ve worked at an OTA, flight tech startup, or airline — and understand the quirks of flight distribution systems and shopping/booking logic.

🚀 You thrive in startup environments — comfortable wearing many hats, shipping fast, and solving messy real-world problems without perfect specs.

🧰 You have 5+ years of experience in fullstack or backend engineering, with strong fundamentals in JavaScript/TypeScript, Node.js, and Next.js.

🗃️ You’ve worked with GDS/NDC platforms, Duffel, Travelfusion, or similar flight APIs — and know where things break (and how to fix them).

⚡ You’re confident with MongoDB or other NoSQL databases; bonus if you’ve used caching layers like Redis, Meilisearch, or Elastic to improve performance.

🔍 You know how to debug flaky flight results, investigate booking failures, and build smart logging and monitoring into every system.

🌐 You’re familiar with Vercel (or similar platforms) and know how to manage staging, previews, and multiple deployment environments.

🔐 You build APIs with security in mind — authentication, authorization, rate limiting, the works.

📬 You’ve worked with queues like QStash and understand how to build reliable, event-driven architectures with retries, dead-lettering, and async workflows.

🏗️ You think in systems and architecture, and care about building platforms that are scalable, observable, and maintainable.

💬 You’re a clear communicator who can work independently and collaborate effectively in a distributed, async team.

🔥 Bonus: You’ve integrated payment systems (BNPL, crypto, wallets) or built loyalty/rewards features in previous products.

Why This Role Is Special

🛫 Direct impact on our core product — you’re building the engine, not just features

🧠 You'll work with ex-Agoda, Booking, and ShopBack founders — no fluff, just domain depth

🏎️ Zero bureaucracy — decisions get made fast, and your voice matters

🌱 Career growth into technical leadership or domain specialist roles

🌍 Help shape a travel product built for this decade — not 2005

What You’ll Get

💰 Competitive salary and meaningful equity

🌏 Remote-friendly work culture, coworking access across SEA

🛠️ Ownership of major systems from early-stage

✈️ Opportunity to redefine travel with a global-first mindset

💬 Mentorship, product visibility, and a high-performing team
