Python Engineer

Twisto, a Param Company, is a modern financial services provider in Central and Eastern Europe. With our app, people have full control over their payments - they can defer or split purchases, share expenses, pay invoices, or shop with virtual and physical cards. We deliver clarity, convenience, and fair exchange rates both at home and abroad. We are a company that keeps growing, innovating, and expanding our services to make everyday life easier for our customers.

We’re looking for Python Engineers to join our team who like working in a dynamic product environment and taking ownership of their features. You’ll work closely with product managers, analysts, and other engineers to turn ideas into working solutions. In practice, that means discussing requirements, helping refine how things should work as we learn more, and then building and improving the systems behind them.

• Most of your work will be on backend services written in Python (mainly Django) with PostgreSQL as the primary database and a focus on well‑designed APIs and integrations.

• You’ll be adding new features, but also spending time understanding and improving existing parts of the system, including performance, reliability, and overall developer experience.

• Some tasks are straightforward, others require digging into how things currently work, dealing with evolving requirements, and finding pragmatic, well‑reasoned solutions.

• You’ll take part in code reviews and technical discussions, and contribute to how we design and evolve our systems, including decisions around architecture, trade‑offs, and handling technical debt.

• We collaborate closely across engineering, product, and analytics - ideas are usually shaped together, and engineers are expected to ask questions, challenge assumptions, and propose better solutions when needed.

• We work in 2-week sprints, with most communication happening via Slack and regular team meetings.

Tech environment: Python (Django), AWS, Kubernetes, Docker, Terraform, PostgreSQL, Grafana, etc.

• A place to grow and do meaningful work - We support you in developing your skills, taking ownership of your projects, and sharing ideas that improve the way we work.

• Friendly and open culture - No dress codes, no unnecessary bureaucracy. We’re a close-knit, collaborative team that values transparency and agility - and while we’re not fully there yet, we’re striving for simplicity, supported by the right amount of documentation.

• Flexibility that keeps us connected - We embrace remote work but value face-to-face communication. To stay in sync, we gather at our Warsaw or Prague offices at least twice a month, so being within commuting distance is key.

• Benefits you’ll actually use - MultiSport card, Benefit Card, fresh fruits 🍎 in the office, team events, and at least 5 weeks of vacation per year.

• Be part of something exciting - Twisto is growing in Europe, and your work will directly contribute to that journey 🌍.

• Around 4-5 years of experience in software development, with a strong focus on Python.

• Experience building backend systems (ideally APIs or services in Django).

• Solid understanding of SQL and working with relational databases, including how queries and schema choices impact performance in production.

• Ability to write clear, maintainable code and work with existing codebases, including refactoring and improving code you didn’t originally write.

• Familiarity with Linux/Unix environments and basic scripting.

• Experience working in a team where engineers, product, and business collaborate closely.

• Comfort working in a dynamic product environment, asking the right questions when things are not fully defined, and making pragmatic trade‑offs between speed and quality.

• Strong communication skills and willingness to explain your decisions, give and receive feedback, and collaborate through code reviews and design discussions.

• Ownership mindset - you treat the services and features you work on as your responsibility, caring about their reliability, observability, and long‑term health.

• English at B2 level or higher; Czech or Polish is an advantage.

• Experience in fintech or payment systems (e.g., card processing, transaction flows).

• Exposure to cloud infrastructure (AWS) or containerized environments.

• Experience with system design for backend services (e.g., event‑driven patterns, asynchronous processing, or designing APIs used by multiple teams).
