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. From enabling a Fintech to launch their first investment product, over allowing e.g. a Neobank to embed investing into their product to bringing investing into a completely new context. Our API-first infrastructure makes launching an investment product customer-centric and compliant. We abstract all complexity for our partners through a well documented API, a self-service customer operations portal and operating in a clear regulatory framework. Enabling partners to launch in weeks, not months.

We have experienced first hand that brokerage infrastructure is broken. Building an investment product used to be highly expensive, challenging and cumbersome. We ease this pain by shielding our partners & their customers from the underlying complexity - and with that, we make investing more accessible to everyone. Because that’s exactly what we enjoy, going to places nobody else dares and solving hard problems. This not only creates tons of value when done right, but attracts the smartest minds - because outlier companies are built by exceptional (& diverse) people like you.

Your Mission:

As a Data Engineer at lemon.markets you will play a key role in designing and maintaining the end to end pipeline of data transmission. You will be the responsible and accountable person for the Data Warehouse ensuring Correctness, Availability, Performance and Security of the data.

You will be part of the Operations Tooling (OT) domain in lemon.markets. The OT domain powered by Retool facilitates all the operational day-to-day work arising from our brokerage platform comprising Customer Lifecycle, Order Lifecycle and Post Trade domains. In a nutshell, Retool is the GUI for data powered by DWH to facilitate Customer, Securities and Cash Operations. Apart from operational work, Retool is also the basis for doing analytics for various activities that our brokerage platform performs. From customer onboarding to order placement and cash and securities settlements.

Our Tech Stack is Python, Airbyte, Redshift, DBT, AWS, Temporal, Retool and Postgres. While you could have worked in different modern tech stacks prior, you should be excited to work with these tools and learn them if you haven’t worked with them before.

You will have a significant impact on the development and maintenance of our core platform & systems - and thereby architectural decisions, as well as on the business itself. You are the first point of contact for internal functions regarding day-to-day functionality of dashboards and can reliably solve issues in a professional manner. 

Work alongside a cross-functional team of experts, and together we will leverage your previous experiences to build the investment infrastructure for the next 100 million retail investors in Europe.

About you:

• You have the ability to write well-structured and tested code in more than one high-level programming languages like Python, Scala or Java, plus another language such as Javascript.

• You have knowledge of data warehouse architectures (e.g., Snowflake, Redshift, BigQuery).

• You have a track record of designing, building and operating reliable and scalable ETL pipelines.

• 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 more than one 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 to do the same via code reviews.

• You should be able to write high quality documentation catering to both technical and non-technical stakeholders

• You have good problem-solving skills and the ability to provide in-depth evaluations and analyses of unique and complex technological issues.

You will be successful in this role if:

• Growing investment opportunities excites you. We operate in a highly regulated environment and therefore having worked prior in a Fintech or financial Service provider would give you a head start, but is not a must.

• You see yourself as a product engineer. That means, you are excited by solving customer problems and strive to become an expert in the domain area you are working in.

• 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 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, sharing knowledge & providing mentorship 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. You are able to work with a small team in a lean environment, can move quickly and focus on what's truly important.

We're looking for people with passion, desire to learn and that are team players. You're encouraged to apply, even if your experience doesn't precisely match the job description. Your skills and passion will stand out—and set you apart—especially if your career has taken some extraordinary twists and turns.
