What you’ll do

- Build real products end-to-end: Take features from idea to production — backend, frontend, and everything in between
- Own the experience: Develop APIs in Go and interfaces in React that are fast, reliable, and intuitive
- Ship fast, iterate faster: Work in a startup environment where speed and learning matter
- Work close to the product: Contribute to product decisions, not just implementation
- Keep things simple and scalable: Write clean, maintainable code and avoid unnecessary complexity
- Integrate systems: Work with REST/GraphQL APIs, auth flows, and external services
- Operate what you build: Deploy, monitor, and improve systems in production
- Leverage AI in development: Use tools like Claude Code to accelerate development, debugging, and iteration
- Support users when needed: Help investigate issues, respond to incidents, and improve reliability based on real usage

What we’re looking for

- Experience building products in startup environments
- Strong skills in Golang (backend) and React (frontend)
- Hands-on experience with AI-assisted development (e.g., Claude Code or similar tools)
- Solid fundamentals in software engineering and system design




- Experience with PostgreSQL and API development (REST/GraphQL)
- Familiarity with Docker and cloud environments (AWS is a plus)
- Experience handling production issues / user support / debugging real-world problems
- Pragmatic mindset: you know when to go deep and when to keep it simple
- Team player with clear communication and ownership

What matters here

- You build things that users actually use
- You care about product, not just code
- You can move fast without breaking everything
- You take ownership — including when things fail

What We Offer

- 25 days annual leave, plus public holidays in your country of residence
- 5-day carryover allowance, usable within the first 3 months of the following year
- Stock options for everyone — 1-year cliff, 4-year vesting
- Annual salary reviews
- Bonus scheme — after 6 months, company-wide and tied to MRR targets
- Remote-first, ideally located within GMT+0 to GMT+4 for time zone overlap.
- A transparent, high-trust, high-intensity, zero-micromanagement environment where we care about outcomes, not hours.
