Senior Python Developer

Who are we?

If you are a Senior Python Developer who values intellectual sparring, direct influence on solution design and seeing your ideas implemented from day one, this is your opportunity.

The StratsLab Difference: Why You Should Read This

We were founded in 2015 by alumni of the Warsaw University MIM Faculty, who spent years sharpening their skills at top-tier investment banks and hedge funds in London. We brought that exclusive, high-impact culture back to Warsaw.

• Developer-Driven: You will be surrounded by top-notch Developers who genuinely love to code. We prioritize writing new code over maintaining legacy systems.
• Unique Domain: You'll gain unique, marketable skills working directly in the highly specialized area of commodities trade risk assessment. This isn't generic IT - it's highly challenging and intellectually rewarding.
• Real Impact: You will have independent, responsible tasks and will have a chance to implement your ideas, seeing the immediate effects of your work on complex financial systems.

Our Roots & Your Fast Track:

We are proud of our origins. Since many of us are alumni of UW (JSIM, CS, Math, Physics), Matex at Staszic and finalists of the Informatics or Mathematics Olympics, we know what it takes to get there. If you share this background, just apply and we guarantee you an intro call. We speak the same language, so let’s skip the formalities.
While we value our roots, we value exceptional engineering even more. If you are a high-calibre developer from a different path, your skills are the only credential that matters. Apply, and let your code do the talking.

Your Role: The Challenge Ahead

You will be working in international teams, serving customers from financial institutions. You will participate in the implementation of risk management software: adjusting it to customers' requirements and developing new functionalities & applications.

• Technical Focus: The backend is mainly in Python. You can expect to spend around 70%+ of your development time in Python, with exposure to C++, Go, Rust and TypeScript. We are multi-cloud and are currently in production with AWS and Azure.
• Code Flexibility: We expect you to be able to be comfortable reading code in any language. We do not expect you to be an expert in all of them, but we do require you to be OK with doing a minor change from time to time in a tech stack you aren't using daily (don't worry, it will be reviewed before merging).
• Work Environment: You configure your work environment yourself (default is macOS, but you have complete freedom in using the software that makes you happy and productive).

What Makes You the Right Fit?

We are looking for specialists whose expertise is built upon a rigorous academic foundation and proven technical skill:

• Academic Foundation: A degree in Computer Science, Mathematics, Physics or other relevant field.
• Core Skills: Advanced knowledge of software design, data structures and algorithms.
• Technical Breadth: Exposure to multiple programming languages and paradigms.
• Communication: Good interpersonal and communication skills with openness to work with customers.
• Language: Very good command of English (also spoken).
• Experience: Financial knowledge and/or experience in financial markets will be an advantage. Familiarity with cloud computing such as AWS / Azure / GCP is a plus.

Collaborative Work Model

We thrive on interpersonal relations and the ability to solve the most complex problems together, that’s why we’re looking for individuals who want to come to the office most days to solve problems together with the team by a whiteboard.

The Offer:

We believe that high-calibre work deserves exceptional support:

• Compensation: Base salary plus a bonus twice a year. Your role and salary are based on your skills and how fast you learn, not just your old job title.
• Professional Growth: You will work closely with experts and gain exposure to top financial institutions as a natural part of your day. Being in this team means you share knowledge with exceptional programmers and grow your expertise through your daily interactions.
• Office: Powiśle, Warsaw.
• Flexible working hours.
• International business trips for volunteers.

The Next Step: Our Selection Process

If all goes well, we are going to spend a lot of time together. Our process aims to ensure both you and us know what we are getting into:

• Informal Introduction: You will start with a casual chat with our Founders to see if we are a good fit for each other.
• Technical Assessment: You will do a technical task so we can see how you code and solve problems.
• Team Engagement: You will meet the team and talk about the role directly with the people you would be working with.
