Senior Software Engineer (Python) - Trust Assurance

About the job:

• Maintaining top-tier safety standards at macro scale: Allegro is a safe platform for millions of users. You will design, develop, and maintain backend systems that keep frauds and policy violations at an absolute minimum.
• Designing core data-sharing and transparency platforms: You will design, develop, and maintain high-security internal platforms responsible for trusted data exposure and compliance. Instead of dealing with legacy external tech, you will build modern abstraction layers that handle data flows, strict auditing, and access control.
• Data-driven engineering culture: We focus on automation, clean documentation, and code optimization. We actively eliminate repetitive manual work in favor of building stable, scalable system solutions.
• Mature and collaborative team: You will join a 6-person team with a strong senior presence. We heavily value engineering craftsmanship, knowledge sharing and high architectural autonomy.
• Technological Compliance & R& D: You will design solutions where advanced backend architecture meets evolving regulatory landscapes and market dynamics. Your work involves building intelligent tools that guarantee the transparency of our marketplace and quickly adapt to sophisticated, creative patterns, making our marketplace resilient to any emerging risks.
• Pragmatic Tech Stack: We select the best tools for the job rather than sticking to one framework. Our ecosystem includes JVM languages and Python. We process data using BigQuery and Spark jobs, utilize graph, relational and document databases, and implement traditional Machine Learning models to support decision-making.
• Driving Automation: You will play a key role in transforming how we handle verification processes. We are moving heavily towards automation to make our systems faster, more accurate, and less reliant on manual intervention.

Important things for you:

• Flexible working hours in the hybrid model (4/1) - working hours start between 7:00 a.m. and 10:00 a.m. We also have 30 days of occasional remote work.

What's in it for you:

• A 16" or 14" MacBook Pro or corresponding Dell with Windows (if you don't like Macs) and all the necessary accessories.
• A wide selection of fringe benefits in a cafeteria plan - you choose what you like (e.g., medical, sports or lunch packages, insurance, purchase vouchers).
• English classes that we pay for related to the specific nature of your job.
• A training budget, inter-team tourism (see more here), hackathons, and an internal learning platform where you will find multiple trainings.
• An additional day off for volunteering, which you can use alone, with a team, or with a larger group of people connected by a common goal.
• Social events for Allegro people - Spin Kilometers, Family Day, Fat Thursday, Advent of Code, and many other occasions we enjoy.
