We’re hiring Senior Frontend Developer (Freelance)

We are looking for an experienced frontend developer to join our team in Brno. We offer freedom, varied work on interesting projects, and the opportunity to influence how the entire development team operates. In return, we expect you to be happy to share your know-how with the team, communicate well, and not be afraid to take ownership of projects.

Job description

What do we do?

We create customer experience. Services, marketing strategies, successful brands, websites, e⁠-⁠shops, and other digital channels — designed to generate revenue for clients and meet long⁠-⁠term goals. We are analysts, researchers, designers, marketers, developers, and project managers. We build on data and research, not assumptions. That's what gives our work meaning — for clients and for us.

"When I joined Proof & Reason years ago, I thought of it as just another web agency. I never imagined I'd stay this long. We work on genuinely interesting projects, I can work whenever I want, and on top of that I can keep growing all the time."

Tomáš Bohdálek

Head of Frontend Development, over 7 years at Proof & Reason

What awaits you here?

  • development of mid⁠-⁠sized and large e⁠⁠-⁠⁠shops, web applications and lead⁠⁠-⁠⁠generation websites,
  • working with modern technologies – Next.js, React, Storybook, SASS (BEM), Tailwind,
  • developing scalable and reusable components, sometimes entire design systems,
  • working on 4–6 projects per year, usually long⁠-⁠term engagements,
  • every project is always managed and planned by a project manager, so 99% of direct client communication is on them.

We care about quality, so your work will include:

  • clearly defined workflow and deployment process,
  • mutual code reviews,
  • tools for maintaining code quality (coding standards, static analysis).

What do we expect from you?

  • at least 4 years of experience developing web applications in TypeScript, React, and ideally Next.js,
  • ability to build a complete frontend solution – from styling through components and API integration to deployment and performance optimisation,
  • you write maintainable and readable code,
  • you can use Git,
  • working in a team is second nature to you,
  • and most importantly – you keep your word and meet deadlines, because everything else can be learned along the way.

What's in it for you?

  • freelance contract for 30–⁠40 hours per week,
  • a fair rate – 650–⁠850 CZK/hour,
  • offices in central Brno (near Lužánky), or in central Prague (near I. P. Pavlova square),
  • option for full remote collaboration

And on top of that:

  • a reliable project team that will always prepare precise briefs and won't chase you late at night or on weekends,
  • a friendly team where you'll have nine developers by your side, sharing their know⁠-⁠how and ready to help with anything at any time,
  • fair and open⁠-⁠minded treatment – we won't have you blindly executing someone else's orders; instead we're open to discussion and love figuring out how to do things better, so that work is enjoyable for you and delivers the best results for clients,
  • room for learning and growth across technologies – we don't like monotony and constantly come up with new solutions. 
"Before joining, I was worried that e-shops would be churned out like hotcakes and the work would be very repetitive. I was quickly proven wrong — the complexity of e-shop backends genuinely surprised me. I also appreciate that we're not tucked away in some industrial zone or tech park, but in a quiet spot in the city centre."
