With offices in London and Vilnius, Architus has a strong track-record in Financial Services and the Fintech world with clients including Invesco, Capital Group, Schroders, BNP Paribas and HSBC.

The opportunity

Architus are partnering one of the fastest growing Fintechs in Europe to help establish a significant presence in Lithuania. The company has over 1000 employees globally, a positive revenue stream and recently secured $100m funding to accelerate its global expansion.

There are a number of opportunities for mid-level engineers to become part of the company’s first engineering group to be based in Lithuania, working alongside other mid-level and senior engineers in Lithuania, London and other international locations.  With 30 employees based in Lithuania already, we will grow significantly further in 2023!

This is a full time role that provides a unique opportunity for an exciting career path working on international projects.

What you will be doing

You will be a key member of an agile engineering team, working on strategic projects including Payments and Open Banking, Credit, Loans,  and Startup Services for a rapidly expanding international company at the leading edge of banking technology.

You will be actively collaborating with other Backend and iOS, Android, Web, QA, DevOps, Data, and Product teams to translate requirements into well-engineered solutions. You will be able to join the Fintech company's backend Community of Practices, learn from them, and propose your own practices to maintain high quality across the backend. This role offers an exceptional opportunity to make a real difference in an international business.

Here is an outline of the technology landscape:

“On the backend we see Java 8 as legacy and use Java 11+ for our micro-services. We provide RESTful APIs to our colleagues in the frontend. Spring Boot is our work horse, but we are open to new experiments. We are cloud-native and run everything on AWS. You’ll see containers (Docker), queues (SNS+SQS, Kafka) and events everywhere. The nature of our business naturally fits with relational databases, but we have also found some use cases for NoSQL. Our frontends have done an incredible job at consuming our APIs and providing the best UX to our members. They are native Android and iOS apps or Angular 2+ web apps. The Cloud Engineering team provides us with vital infrastructure and DevOps support on the cloud.”
