Job Description

Location: Amsterdam, Netherlands (relocation & visa) or remote (European time zones).

WHO WE ARE

After the 2008 financial crash, the international financial and business environment is more regulated than ever. The amount of required paperwork has increased exponentially. The deals are being blocked, the accounts are being frozen, the business is often getting paralyzed.

Project Plato was born in 2015 as an autonomous R&D unit working for Dolfin, an established British investment company, with the aim of automating sensitive business operations. We are a young and ambitious team frustrated by inefficiency of existing solutions.

5 years later, with the help of our software solutions, Dolfin was able to have

• $4.1bn in client assets under management
• $650m monthly brokerage flow
• 10x increased speed of customer and employee onboarding
• 30x more efficiency of its compliance officers

But this is only the beginning. Our mission is to help companies and business professionals around the world communicate with each other and do business with trust and simplified paperwork.

OUR TECH STACK

As a serious, business-oriented company, we develop our solutions exclusively in COBOL.

Just kidding! We use modern and diverse IT infrastructure. Our solutions are web-based, with backends in Golang andPython and frontends in Typescript and React. Data storages include PostgreSQL, DynamoDB and Amazon S3. The infrastructure consists of multiple backend services managed via Kubernetes/Helm, integrated with various AWS and third-party services. We also use Google Bazel, a secure and robust build system.

We strive to make our development process predictable, change-proof and well-organized to achieve the fastest possible product delivery pace without compromising reliability.

OUR TEAM

We are still small: Project Plato is less than 15 people in total but we are planning to grow to 20 soon. As part of the Project Plato back-end team, you will be working closely with Oleg and another 3 senior engineers. Oleg is our lead backend engineer who has been part of the team since 2015 when we established our office in Amsterdam.
