Senior Full Stack Engineer (Frontend-Heavy) - Ship Fast, Own the Front ( English Mandatory )
We move fast. Our CTO ships backend at a pace most engineers have never worked at. We need a full stack engineer who matches that energy on the frontend - not someone who needs managing, but someone who takes ownership and gets things done.
The context
We're a travel tech and fintech company - ticketing, booking flows, buy-now-pay-later travel finance, and real-time API integrations. The product is consumer-facing, which means every millisecond, every loading state, every error message matters. Our CTO leads backend with high autonomy and high output. We're looking for a full stack engineer who can own the entire frontend and jump into backend when needed - no hand-holding, no constant direction. We're a lean team. You won't have a manager reviewing everything PR. You'll be talking directly with the CTO and moving things forward daily.
This is a full-time position. We are not consulting part-time or freelance arrangements.
What you'll build and own
- Complex booking and ticketing UIs - search, filtering, availability, payment flows
- Travel finance and BNPL flows - installation plans, elegibility checks, payment scheduling UIs
- Third-party travel and fintech API integrations on the frontend (fare coaching, async availability calls, lending APIs, error handling)
- Performance - Core Web Vitals, caching strategy, received speed on travel search and finance results
- Component architecture that scales across both travel and fintech products
- Consumer-grade polish - transitions, empty states, loading skeletons, responsible layouts across devices
- Backend contributions longside the CTO when needed
- Direct collaboration with the CTO on architecture decisions, daily

Who you are
- Full stack engineer with 5+ years of experience - strong on the frontend, capable on the backend
- Fluent in English - written and spoken. This is a mandate. All communication happens in English
- You've worked on transactional, data-heavy UIs - travel, fintech, e-commerce, marketplace - where state management, reliability API, and financial accuracy matter
- You use AI tools (Cursor, Copilot, Claude, or others) as a genuine productivity multiplier - not as a crutch, but as a way to move faster with more confidence
- You're comfortable owning an entire frontend codebase without someone telling you what to priority next
- You're available full-time and can overlap with European working hours
- You communicate clearly and early - you flag blockers before they come problems
This role is not for you if
- You work slowly because you're waiting for perfect specs
- You've never shipped a consumer product used by real paying users
- You need detected tasks to know what to work on
- You're not yet using AI tools actively in your development workflow
- English is not your working language
- You're looking for anything other than a full-time engagement
To apply - short, direct answers only. We value clarity.
- Share a Next.js project you've built or signedly owned - what was it, what was hard about it, and how did you solve it?
- Describe how you use AI tools in your day-to-day development. Be specific - what tools, in what situations, and how has it changed your output?
- Have you built any travel, fintech, or booking-related UI? What was the most complex front-end challenge in it?
- We ship daily. What does your process look like for balancing speed with not breaking things?
