Job description

🌍 Hello World!

We are The Codest – International Tech Software Company with tech hubs in Poland delivering global IT solutions and projects. Our core values lie in “Customers and People First” approach that prioritises the needs of our customers and a collaborative environment for our employees, enabling us to deliver exceptional products and services.

Our expertise centers on web development, cloud engineering, DevOps and quality. After many years of developing our own product – Yieldbird, which was honored as a laureate of the prestigious Top25 Deloitte awards, we arrived at our mission: to help tech companies build impactful product and scale their IT teams through boosting IT delivery performance. Through our extensive experience with product development challenges, we have become experts in building digital products and scaling IT teams.

But our journey does not end here – we want to continue our growth. If you’re goal-driven and looking for new opportunities, join our team! What awaits you is an enriching and collaborative environment that fosters your growth at every step.

Project Description:

In this role, you'll contribute to a banking app for a leading financial group in Japan. The app serves as a cross-asset post-trade execution platform, integrating with third-party services for trade matching and settlement. It efficiently handles large volumes of trade data and offers features like a Trade Blotter and position reporting. While new features are continually added, the core product is already established.

The client has undergone a significant architectural transformation. Previously, much of the business logic lived in the database and was exposed via GraphQL using Hasura. Today, the company has moved to a new architecture: the database contains only tables and views (with rare exceptions), and all application logic is now implemented in a Python-based middle layer. This layer still uses GraphQL (powered by the Strawberry framework), but REST is also being introduced as a complement or alternative in selected scenarios.

While database knowledge remains relevant, it is now limited to fundamental operations: managing tables and views, basic indexing, and performance analysis

Your Responsibilities

• Write clean, testable, well‑documented, and maintainable code.
• Participate in planning, design, testing, and code reviews.
• Build rapid prototypes and contribute to fast‑paced projects.
• Collaborate effectively with a distributed team.
• Recommend and implement continuous improvements.
• Mentor fellow engineers and promote engineering best practices.

Key Requirements

• Advanced English in speaking and writing (you will be working with international clients only)
• 5+ years of commercial experience in Python
• Strong knowledge of relational PostgreSQL database
• Good knowledge of database performance issues, indexes and the SQL language itself
• Experience with Git and GitLab.
• Familiarity with Linux environments.
• Experience with cloud platforms such as Azure or AWS.
• Understanding of CI/CD tools and continuous delivery practices.
• Familiarity with Agile methodologies, especially Scrum.

Our Promise (what you can expect from us)

• 25000 – 28000 PLN on B2B/useme
• Opportunity to work on modern, well‑architected systems with clean separation of concerns.
• Real influence on technical decisions and system design.
• Collaboration with experienced engineers in an international environment.
• Stable cooperation and a clear onboarding process.
• 100% remote work (but we have offices in Krakow and Warsaw and we’re happy to meet there from time to time 😉)
• 300 PLN to use on our benefits platform, Worksmile – gift cards, medical services, sports, etc.
• Our B2B contract contains provisions that allow you to obtain IP BOX support
• Integration events, education opportunities and much more…
• A unique opportunity to take your career to the next level – we’re looking for people who want to create an impact. You have ideas, we want to hear them!
