About this role
We're looking for an experienced Senior Full-stack Developer who takes ownership of features end-to-end and actively integrates AI tooling into their daily workflow.
You'll join a long-term project in the alternative investments domain, helping to improve and scale a platform that simplifies the entire investment process — from onboarding and compliance to reporting and insights.

- Hands-on practice with AI spec-driven development — you actively use AI tooling as part of your daily workflow, not occasionally

- English: C1 (Advanced) — comfortable in async written communication and on calls
### Will Be a Plus

### Responsibilities
- Build and maintain scalable backend services using PHP/Symfony and modern frontends in React/TypeScript

- Write and maintain tests using Playwright (TypeScript)
- Collaborate with the team via Jira, Confluence, Bitbucket, and Figma
- Participate in code reviews and contribute to raising the team's technical bar
### Tech Stack
- Backend: PHP 8.3, Symfony 5.4, API Platform 2.6, Doctrine, Symfony Messenger
- Frontend: React 17 + TypeScript
