About the project

Allegro Pay is Central Europe's largest and fastest growing fintech - the only place where financial solutions can be created on such a large scale, using state-of-the-art technology. We work on purchase financing and payment methods that are used daily by customers of Allegro, the most popular shopping platform in Poland and one of the largest e-commerce companies in Europe. Due to this scale, we have the opportunity to work on one of the most exciting purchase financing and payment solutions in our country. We are looking for talented people who want to create powerful and stable solutions to support a product with over a dozen million active users.

The role

We're looking for a Software Engineer with solid, proven experience in .NET and backend development to join a cross-functional team focused mainly on greenfield projects — building new products and features from the ground up. You'll take ownership of designing and delivering seamless, end-to-end customer journeys — from opening a bank account and activating a fast payment method directly within the Allegro app, through funding the account, to authorizing payments and rewarding customers with cashback, all in just a few taps. Alongside building new features, you'll drive improvements in system performance, scalability, and reliability, and help raise the quality and maintainability of our codebase. You'll work closely with product, design, and business stakeholders, translating ideas into robust technical solutions, and collaborate with and support less experienced teammates as the team grows.

Our team builds and scales two products:

Allegro Klik - lets Allegro users link an existing bank account or open a new one directly within the Allegro app for instant payments with cashback. We own the full flow: account linking and opening, payment processing, top-ups, cashback calculation and cashback-driven promotional campaigns.

Allegro Care - insurance offered directly in the Allegro shopping experience, letting customers protect their purchases (e.g. against damage, theft, or with extended warranty) right at checkout, with policy management handled seamlessly within the platform.

Both products are growing fast, with new initiatives launched continuously alongside scaling of our existing systems.

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.

The salary range for this position depending on the skill set is as follows (contract of employment, tax-deductible cost):

- PLN gross 14 600 - 20 825

- Annual bonus based on your annual performance and company results.

Our team is based in Warsaw and Poznań.

Your responsibilities

AI-Adoption strategy: we invest a lot of effort to upskill our specialists and equip them with the newest AI coding technologies like Copilot or OpenCode.
Big Scale: immerse yourself in the exciting world of Allegro Pay, where your .NET skills will tackle challenges on a large scale. You'll be contributing to financial solutions that affect over 2.5 million people (handling 60+ million requests daily and managing dozens of terabytes of data).
Engineering Maturity: Join a culture that mirrors the top tech giants. Our commitment to engineering excellence and maturity puts us on par with industry leaders like FAANG companies. (11 of 12 in Pragmatic Engineer Score)
Best-in-Class Expertise: Work alongside the best experts in the field, collaborating to push the boundaries of what's possible in FinTech. Our team includes MVPs and many conference speakers.
Impactful Products: Imagine this – your work at Allegro Pay contributes to creating products that you, your family, and friends might already use daily. See the direct impact of your efforts on the FinTech landscape (with 120+ deployments per month).
