What We Offer

• $64K – $113K gross annual salary.

• We can support your relocation to Portugal if you want.
• A significant impact: Work in a small, dedicated team, collaborating directly with startup founders and engineers. You won’t just close tickets—you’ll shape products, care for the business, and solve real user problems.

• Most of the people in your team can code, including founders, managers, and designers.

You Fit This Position If

2. Think like a product owner. You are driven to understand the “why” behind your work. For you, engineering is about helping people and businesses succeed. You understand the processes of a modern startup.
3. You don’t just use a step-by-step guide instead always try to learn your tools very deeply.
4. A “manager of one.” You are a master of your own time and can work effectively without micromanagement. You practice careful reading, clear async communication, and proactive questioning.
5. You have good English writing skills and aren’t afraid to speak on calls.

How to Apply

Don’t send us a standard CV.

Send us an email with your full name as the email subject.

In your email:

1. Link to the best login form you implemented. We will check UX, attention to details, and accessibility. If you don’t have one, create an SPA:
   • With an email/password sign-in page
   • Without a UI component library.
   • You need to think about sending email/password to a server, but you can skip building the server by mocking fetch().
   • Deploy the example on GitHub Pages, and send a link to the final interface and sources.
2. About you. Describe your projects, achievements, and how you contributed to their success.
3. Location & relocation. Mention your current location and if you’re open to relocation. We do not hire in Russia.
4. Community results. Share any open-source contributions, conference talks, or community involvement to get extra “life” during the hiring process.

If you already have a lot of consultancy experience with US clients and open-source/talks impact, mention it in the email, and we can speed up the process.

What You’ll Do

• Explain your decisions and architecture.
• Be the “manager of one”: clarify your tasks, set expectations, provide transparency with clear communication and accountability, and bring your best work and opinions proactively.
• Ask for help without waiting for a “better moment”.
• Build UI, frontend, and backend with TypeScript, and set up build and quality control tools. The choice of a tool always depends on a task, but we often use React. Knowledge of the server-side (Node.js) is a big plus.
• Code alone or in a team; in many cases, one or two of our Frontend Engineers work on a project.
• Work with different code bases: refactor old code as well as build greenfield projects.
