Company mission
To pave a new era of brokerage by building the infrastructure for FinTech companies to launch an investing feature or product in Europe.
Role
Who you are
- You have the ability to write well-structured and tested code in high-level programming languages like Python, plus another language like Javascript, Typescript or Go
- You have excellent knowledge & experience around web frameworks, preferably FastAPI; alternatively, you have experience with Flask, Sanic, Tornado, or Falcon
- You have proven experience designing and implementing highly scalable architecture and reliable REST APIs and bring the desire to make them world-class
- You’ve gained good experience with AWS Services such as EC2, EKS, S3, RDS, or Athena
- You have a very good understanding of open source databases such as PostgreSQL or memory-databases like Redis; experience with time series databases like QuestDB is beneficial but not a must
- You know your way around API Gateways - experience with Kong gives you a head start
- You have good understanding and experience with streaming or messaging platforms, ideally Kafka
- You gained hands-on experience with testing different entities, use-cases, and 3rd party integrations - preferably writing tests with pytest
- You have a solid understanding of distributed systems
- You have excellent problem-solving skills and the ability to provide in-depth evaluations and analyses of unique and complex technological issues
- You are familiar with app containerisation with Docker, knowledge of Kubernetes is a plus
- Growing investment opportunities excites you. We operate in a highly regulated environment and therefore having worked in a Fintech or financial Service provider (Bank, Insurance or Brokerage) would be preferable and would give you a head start
- You enjoy building from scratch. This means high involvement in the product development process itself while advocating for the best engineering practices. It also means that you enjoy taking technical decisions
- You have a bias for action over a discussion. To avoid getting stuck in a discussion, you collect new feedback, try out a different approach or gather data with a proof of concept because you trust the process
- You are ready and willing to take ownership of problems and act on them decisively with no supervision. You always thrive for high quality outcomes through focus, determination and attention to detail
- You are a team player. Working together as a team and sharing knowledge comes naturally to you. Long term - you consider becoming a team lead
- You have no problem with learning new technologies on the go. You try to solve problems with more things than the ones you already know. We will always enable you with that, but your willingness has to come first
- You understand what working in a startup or a similar lean organisation is like. Working in an early-stage startup can be somehow frightening, overwhelming, and amazing at the same time
What the job involves
- As Senior Backend Engineer you will play a key role in designing the backend services and architecture of our brokerage API that will allow other companies to easily embed investing into their product
- You will take ownership of features and services ensuring they run smoothly on production, while collaborating closely with the product team, Infrastructure, and DevOps engineers
- Your main objective will be to build our flagship product - the Brokerage API - from scratch, but you will also improve the reliability and performance, and extend the functionalities of our existing Trading API over time
- Joining our compact & dedicated team of Backend and Infrastructure Engineers, you will have a significant impact on the development of our Brokerage API - and thereby architectural decisions as well as on the business itself - from the first lines of code to the product’s launch and beyond
Our take
Though stock trading is a growing market, the European market has historically lacked the required tech and infrastructure required for companies to implement brokerage offerings into their systems. Enter lemon.markets, a next-generation API-first solution for stock trading which enables developers to build their own investment and trading tools from a single, easy-to-use API platform.
Bridging the gap between European tech firms and functional stock market trading capabilities, the company’s infrastructure enables full management of brokerage accounts, and easy retrieval of historical and real-time market data, all through a simple dashboard or mobile app.
After securing one of 2022’s largest seed funding rounds in Europe, which was co-led by Lakestar and Lightspeed, lemon.markets is focusing its efforts on becoming a regulated brokerage provider, furthering product development, and deepening its core partnerships. The young company is well-positioned to see substantial growth as it extends its capabilities and cutting-edge infrastructure.
