Deine Aufgaben und Verantwortlichkeiten

Develop and maintain backend services powering regulated financial products
Work across multiple projects — from building new and maintaining existing Python-based solutions to building new services in Go or Rust
Design and implement cloud infrastructure using Terraform (AWS, Azure, On-Prem)
Build integrations with external financial services, tackling real-world challenges around asynchronous processing and data synchronization
Take ownership of delivering high-quality, production-ready systems in a highly regulated fintech environment
Leverage AI-assisted development tools thoughtfully — we embrace them but never at the cost of security or quality

Deine Qualifikationen und Erfahrungen

Experience in manual and automated testing across APIs, web applications, and mobile apps.
A meticulous, detail-oriented approach — in fintech, the details matter!
Ability to quickly understand complex business domains and translate requirements into thorough test strategies.
Strong communication skills — you'll work with developers, business analysts, and external clients.
A proactive mindset — our QA engineers are not just testers, they're active participants in shaping the product.
Eagerness to learn and adapt — you'll ramp up quickly on trading markets, financial regulations, and platform-specific knowledge.

Nice to have

Solid experience with "Python"
Openness and willingness to work with "Go" and/or "Rust" — you don't need to be an expert, but curiosity matters
Experience with cloud platforms and infrastructure-as-code (Terraform)
Understanding of distributed systems concepts — event-driven architectures, message queues, eventual consistency
Ability to work autonomously while collaborating with a team
Comfort operating in a regulated environment where quality and reliability are non-negotiable
