Senior Backend Engineer (f/m/x)

About lemon.markets

Our mission is providing better opportunities to invest in capital markets. By empowering FinTechs and Banks to offer investment products, we help create financial well-being for their customers. In pursuit of this goal, we strive to open 100 million securities accounts within Europe in this decade.

lemon.markets builds infrastructure for financial services and technology companies powering the next generation of investment products. Our API-first infrastructure makes launching an investment product customer-centric and compliant, enabling partners to launch in weeks, not months.

We have experienced first hand that brokerage infrastructure is broken. We ease this pain by shielding our partners & their customers from the underlying complexity - making investing more accessible to everyone.

Your Mission:

As Senior Backend Engineer at lemon.markets you will play a key role in designing the backend services and architecture of our brokerage API platform. You will take ownership of features and services end to end in cross-functional teams, ensuring they run smoothly on production.

You will focus on areas of the Customer Lifecycle, Order Lifecycle or Post-Trade processes - ensuring our Core Platform & Systems are reliable & scalable.

Our Tech Stack is Python, FastAPI, AWS and Postgres. While you can have worked in different modern tech stacks, you should be excited to work in Python and learn it if you haven’t worked with it before.

About you:

• You have the ability to write well-structured and tested code in high-level programming languages like Golang, Python, Java or Ruby, plus another language such as Javascript, Typescript or Go.
• You have experience in designing and implementing highly scalable architecture and reliable REST APIs.
• You’ve gained good experience with software in a cloud environment (AWS, GCP, Azure) and the architectural patterns for this environment.
• You have a good understanding of document-based or relational database technology such as MySQL/PostgreSQL or MongoDB.
• You know how to write high-quality code that is understandable, maintainable and well tested, and can guide other engineers via code reviews.
• You have good problem-solving skills and the ability to provide in-depth evaluations of complex technological issues.
• You have a track record of designing, building and operating reliable and scalable backend systems as part of a cross-functional team.

You will be successful in this role if:

• Growing investment opportunities excites you. Experience in a Fintech or financial service provider is a plus, but not required.
• You see yourself as a product engineer. You are excited by solving customer problems and strive to become an expert in your domain.
• You enjoy building from scratch. You are involved in the product development process while advocating for best engineering practices.
