Tolgee is a company that develops Tolgee, an open-source tool that simplifies the translation of software and applications into different human languages.

In Tolgee, we aim to revolutionize how teams localize their software by providing multiple killer features, simplifying projects' development, localization and maintenance. Tolgee Platform is the source of truth for storing localization data for various platforms and different types of content. Tolgee currently focuses on localizing applications using modern frameworks like React, Next.js, Vue, Angular or Svelte, where it provides its native SDKs. It also supports many formats for technologies like iOS, Android, Flutter, C++, PHP and more.

We believe in the open-source / open-core business model. It enables us to organically spread the tool without paying huge PPC bills while allowing individuals and open-source communities to use our tool for free. Business-wise, we follow a product-led, sustainable growth strategy.

What we value

We believe in open-source values and are committed to building a strong community. Providing a self-hosted product is an essential part of our philosophy.

• We are transparent. Really. We build our product publicly, sharing our plans as individual tasks on GitHub in public repositories. Everyone can read our code, and everyone can improve it.
• We give people as much freedom as possible while keeping them responsible for the results. We value autonomous people who have ideas and are willing to implement them themselves or find the resources to get things done.
• We ship fast, but at the same time, we provide stable and tested products.

Who we are looking for

You are a Senior Full-Stack Developer with deep back-end experience, solid front-end experience, and a strong focus on security and clean code. You’ve built REST APIs, worked with ORMs, and know how to write and maintain code that is both efficient and maintainable.

But more importantly, we are looking for someone who:

• Looks for challenge – you don’t just look for a job, you look for a mission where your impact is visible.
• Works hard and takes ownership – when there’s a deadline, you’re committed to delivering.
• Wants to grow – both personally and professionally, and is ready to push beyond comfort zones.
• Isn’t here only for the salary – the ESOP makes you a real co-owner of the company. If Tolgee grows, you grow with it.
• Can handle intensity when needed – we move fast, sometimes that means extra effort to get things done.

What you’ll be doing

• Designing, implementing, and delivering roadmap features for the Tolgee Platform.
• Developing or improving and managing various Tolgee SDKs and integrations across frameworks.
• Working on modern AI/ML features: e.g. MCP servers, LLM-based localization, etc.
• Ensuring high standards of secure development, clean code, and good documentation.
• Collaborating with product, design, and other engineering teams to plan, iterate, and deliver significant features.

Requirements

• 5+ years of professional backend development experience
• Proven experience designing & documenting REST APIs.
• Experience using an ORM with relational databases.
• Strong understanding of secure development practices (e.g., avoiding vulnerabilities, authentication/authorization, data protection).
• Front-end experience: with React.js or another modern JS/TS framework.
• Strong code hygiene: writing clean, maintainable, and testable code.
• Working from EU timezones

Salary

• €4,000 – €8,000 / month
• ESOP (Yeah, you will get significant shares in the company)Benefits

• Unlimited vacation
• Remote or on-site - whatever works for you.
• 2-3 meeting-less days per week
• Did we tell you about the ESOP? We have to say it again because not many (if any) companies on the market would offer you 0.1-1% of the company share. (the company grows more then 3x YoY)

Hiring process

We have a 3-round interview process:

1. Intro call (15–30 min): to learn your background, motivations, and ask a few non-popular questions to understand how you work.
2. Technical / experience call (~1 hour): deep dive into your previous work, technical question.
3. Tolgee SuperDay (full working day + fun part). We invite you to the office and give you a real-world task. For the SuperDay, you have to attend personally our office in Brno, Czechia.
