Syberry  is the technology partner for a U.S.-based capital management company, and we are establishing an engineering center in Europe for them. The team is building the technology platform to run the company. This is a greenfield development project utilizing  Python, Kotlin, React, and AWS as the primary tech stack. 

We are seeking a Kotlin/Python Engineer to develop a toolset for portfolio managers that will enable the analysis of financial data and facilitating informed decision-making based on this analysis.

Why join us?

  • Learn from top Wall Street experts:  you will work in one team with quants and portfolio managers who have 15+ years of experience in the field.
  • Greenfield development: participate in designing and building an entire tech platform for running the company from scratch. Our oldest code is just 2 years old.
  • Cutting-edge practices:  we embrace XP principles like TDD, CI/CD, pair programming, and trunk-based development to ship value daily.
  • Real challenges:  everything you work on gets tested by real users immediately. No boring tasks with unknown value.
  • Zero bureaucracy:  were a startup, so the features you produce will be available for the end-users shortly.
  • Small, skilled teams:  we’re a crew of 30 experienced engineers, working in small teams of up to 5 so don’t expect communication overload.
  • True remote: No Return To Office. Work from wherever you want. 

Responsibilities

About you: 

If your main expertise is in PYTHON: 

  • Strong engineering experience (we mean it): we believe at least 7 years of software engineering is a good predictor
  • Experience working with  AWS, GCP or Azure ; can use key services for computation, networking, and storage
  • Exposure to  Java/Kotlin  and readiness to work with Kotlin: our system is developed using both Python and Kotlin. Thats why we expect your readiness to work both with Python and Kotlin
  • Experience using SQL and RDBMS; know how to write requests for relational databases
  • Experience designing and writing API by best practices
  • Experience writing automated tests
  • Experience working with Docker
  • Readiness to learn Infrastructure as Code and work with Terraform
  • Strong mathematics knowledge
  • Fluent English: for daily communication with native speakers from the U.S.
  • Availability until 7 PM CET at least 3 days a week : our product team and end users operate in the Eastern Time Zone, so we need an overlap for effective collaboration. Still, we expect 8h of work daily so you could start later or have breaks with flexibility provided
