Senior Web Frontend Developer (mfd) Remote (based in Romania)

A small piece of paper with numbers that have the power to change a life forever! Okay... lets replace the paper with an app and one person with 610000 monthly users. This is our business!

Your Mission

As Senior Web Frontend Developer (m/f/d) you play a key role in accelerating the web apps journey toward feature parity with our iOS and Android apps which currently lead the product roadmap. As Lotto Scanner continues to scale following our recent investment round the web channel becomes increasingly important for reaching users who prefer to play the official lottery via desktop or browser instead of installing a mobile appdirectly contributing to both revenue growth and user acquisition. By joining as our third Senior Web Developer you expand our delivery capacity helping us close the gap with mobile faster and ensuring web users enjoy a first-class experience.

Your Tasks & Responsibilities

• Deliver features independently. Spend the majority of your time implementing tickets end-to-end from a well-defined task to production-ready code. This is the core of the role.

• Discuss before you build. Bring ideas and any changes to existing patterns or architecture to the web team before implementation. Autonomy on execution is high; autonomy on direction is a team decision.

• Participate actively in Scrum. Contribute to dailies planning refinements reviews and retros including helping select tickets in a way that minimises overlap and merge conflicts.

• Treat code review and testing as first-class work. Review PRs promptly write tests alongside features. Both drive our throughput.

• Collaborate with design and product. Work directly with our designer and PM to clarify requirements sharpen UX and surface technical constraints early.

• Coordinate with mobile on our shared backend. Web iOS and Android share one backend so occasional alignment with the mobile teams is part of the role typically around API changes or features built in parallel across platforms.

• Spot and surface improvements. Raise areas that genuinely need attention (performance reliability code quality DX) with the team. Substance over ceremony.

• Storybook for component-driven development

• Contentful as our headless CMS

• Sentry for error tracking Adjust and Google Analytics for analytics

Your Key Competencies

Must-have

• TypeScript strong working knowledge; we are fully typed.

• React solid command of React 19 including hooks suspense concurrent features and component composition.

• with App Router and React Server Components hands-on experience with SSR SSG streaming and caching. This is the backbone of our stack and we expect deep familiarity from day one.

• Tailwind CSS comfortable building UI with utility-first CSS; this is how we style the app.

• Testing as a habit writes tests alongside features. Hands-on experience with at least one modern testing stack (we use Vitest Testing Library and Cypress); the discipline matters more than the specific tools.

• Senior engineering fundamentals clean code code review debugging performance awareness and knowing when to invest in quality versus ship.

• Remote collaboration in an agile setting Scrum participation async-friendly communication and the ability to drive tickets independently in a high-trust team.

Nice-to-have

• Google Analytics or comparable web analytics platforms.

• Contentful or another headless CMS.

• Accessibility (a11y) and internationalization (i18n) experience.

• Storybook for component-driven development.

• Lottery gambling or other regulated-industry experience.

• Low ego high trust. Agreeable transparent about decisions and supportive of teammates. Team spirit matters more than individual brilliance.

• Responsive communication. Reachable during our core hours (10:0016:00) we keep each other unblocked. Written-first for async calls for harder topics.

• Disagree and commit. Strong opinions are welcome and expected. Voice them hear the counterarguments and once the team has decided get behind it. Once its decided its decided.

• Team-first ownership no blame culture. When something goes wrong a production bug a missed deadline its all hands on deck to fix it not a search for who to blame. The flip side: we expect everyone to take their work seriously and care about the outcome.

• Comfortable with autonomy and remote work. Self-directed and able to drive tickets end-to-end without daily check-ins. Equally comfortable raising a hand when something is blocking silence is the failure mode we watch for.

• Curious about the product. Lotto Scanner has real users and real money flowing through it. We want someone who cares about what is being shipped not just how.

Your Impact in This Role

• Months 13 Onboarding & ramp-up: You build a solid understanding of Lotto Scanner and the web codebase. By the end of month 3 you are comfortable shipping tickets to production with minimal guidance.

• Months 36 Independent delivery: You operate autonomously on features and tickets in our remote high-trust setupasking for input when useful and driving tasks end-to-end without daily direction.

• By month 6 Measurable feature impact: You have shipped multiple production features that move the web app closer to parity with iOS and Android contributing visibly to overall team throughput.

Your Background Education & Experience

• 5 years of web development experience with strong React expertise. Slightly less is fine if clearly operating at a senior level.

• Proven track record of shipping production features to real users ideally at scale with end-to-end ownership.

• Product-focused B2C mindset preferred: experience in product companies is a strong plus.

• Startup or scale-up experience is highly valued: comfortable in fast-paced high-ownership environments.

• Experience in regulated domains (e.g. lottery gambling fintech healthcare) is a plus.

• Degree in Computer Science or similar is optional: we prioritize what youve built and delivered.
