How do we work?
We are an international Scrum team of Full Stack Software Engineers working with React.js, Python, and Google Cloud Platform. We build and optimize registration flows and onboarding forms used by our clients for a seamless, secure onboarding experience.
We place a strong emphasis on continuous improvement, autonomy, cross-team collaboration, and clean architecture.
We work in a hybrid model in Cracow, Zabłocie.
As a Senior Full Stack Engineer, you will:
- Drive the architecture, design, build, and maintain dynamic onboarding forms and registration workflows using React.js and Python (FastAPI).
- Oversee and implement third-party vendor service integrations (APIs/SDKs), ensuring reliability, and collaborate closely with external providers and internal teams across the organization.
- Independently own features and technical initiatives end-to-end — from technical design, analysis, and problem-solving to production deployment.
- Ensure clear communication in English across cross-functional teams, technical stakeholders, and business partners, driving technical alignment and pragmatic solutions.
- Write clean, testable, and efficient code adhering to software engineering best practices (SOLID, Clean Code), championing code quality and conducting constructive code reviews.
- Champion and integrate modern developer tooling (including Claude Code and AI assistants) to streamline development, refactoring, and process automation across the team.
- Lead team technical discussions, mentor other engineers, and continuously drive improvements in our system architecture.
What skillset you need to be successful in this role:
- Extensive commercial experience as a Full Stack Developer working with React.js and Python (FastAPI).
- Demonstrated experience with system design, clean architecture, and cloud environments (preferably Google Cloud Platform).
- Proven experience with third-party vendor API integrations (e.g., identity verification, payment gateways, e-signature).
- Strong command of automated testing tools (PyTest, Cypress, Playwright) and CI/CD pipelines to ensure system reliability.
- Strong English communication skills (C1) for daily collaboration in a multicultural environment and cross-team alignment.
- High degree of autonomy, ownership, and the ability to mentor and support peers.
- Solid understanding of Domain-Driven Design (DDD) principles and Infrastructure as Code (IaC, e.g., Terraform).
- Hands-on experience utilizing modern developer tooling, such as AI assistants and Claude Code, in everyday engineering workflows.
Bonus points if you have experience with:
- Commercial background in the FinTech industry (handling sensitive data, compliance, KYC/AML, or payment systems).
- Driving or contributing to organizational/team transformations toward AI-driven development, automated testing, and developer productivity tooling.
