About The Position
We're building a platform — a unified system used organization-wide to manage and serve content for both web and mobile apps across all markets where InPost operates. The platform gives content editors a visual interface to build and publish pages. Behind the scenes, it's a TypeScript monorepo with a Next.js + PayloadCMS admin panel, an Astro SSR web renderer, and a custom shared design system. We are looking for a seasoned engineer (typically 4+ years building production frontend applications) who understands the complexities of working in a large, international organization. You aren't just a coder; you are a problem solver who understands how technical decisions impact global scalability, multi-market rollouts, and localization. You'll work at the intersection of product, design, and engineering. We expect you to bring experience from other mature organizations, challenge our ideas, and help us navigate the challenges of a multi-language, multi-region platform. We also believe AI is reshaping frontend development. We want someone who has already adapted—using AI tools naturally—and can help the team raise the bar.
Requirements
- Proven experience in an international organization or working on large-scale products serving multiple markets
- Deep knowledge of HTML and CSS (cascade, specificity, layout systems)
- Strong React skills — combined with Engineering thinking: you are a software engineer, not just a React developer
- Experience with Next.js, Astro, or similar modern frameworks
- Strong TypeScript (strict mode, generics, conditional types)
- Experience with multi-language / multi-site architectures (i18n, l10n complexities)
- Solid web accessibility expertise (WCAG 2.1/2.2)
- Experience designing and contributing to design systems
- Understanding of SSR and hydration trade-offs
- Experience mentoring or onboarding less experienced engineers
- Practical experience with AI tools in development
- Ability to work with cross-functional teams and influence stakeholders
Nice To Haves
- Familiarity with PayloadCMS or another headless CMS

- Interest in design token systems and style pipelines
Responsibilities
- Develop new features focusing on architecture, scalability, and internationalization standards
- Take ownership of your solutions — you own the outcome and quality of what you build
- Drive the evolution of our shared design system to support multiple brands and markets

- Experiment with and integrate LLM-based tools into our products and workflows
- Drive AI adoption within the team — help establish best practices
- Work with strict TypeScript to design safe, ergonomic APIs
- Maintain and extend our E2E test suite (Playwright) to ensure stability across regions
- Mentor junior engineers and foster a culture of technical excellence
- Participate in architectural decision-making — we use lightweight RFCs and collective ownership to align on technical direction
Benefits
- Opportunity to work in a diverse, international and cross-functional environment, along with leading experts.
- Fulfilling careers with a range of benefits for employees and invests in providing training opportunities for their development.
- Your impact will be visible instantly and you will be making a difference in our users lives
