Overview
 
Our team is looking for a Trading System Architect and Developer. The ideal candidate is an expert in designing and building a trading system, translating technology and business requirements into trading transactions, which are to be carried out via third-party API calls. Typical activities will include the design of the general architecture (e.g., engines to create transactions, schedulers to regularly update status, vaults for audit-proof storage of transaction data) and delivery of the designed products (incl. assessment and deployment of third-party tools, where applicable, or own development).

Key responsibilities:
•	Co-design the target architecture of a trading system (incl. intake of trading jobs, translating into transactions, execution of transaction via API calls, and related activities such as access management, auditing, or backups)
•	Creation/delivery of the various code elements (incl. setup of server, buy-or-build decisions to either set up of third-party tools where possible, or own coding)
•	Be a partner to the business side to co-define business requirements (e.g., auditing of transactions)
•	Be a partner to external stakeholders to co-define tech requirements (e.g., connection to third-party APIs)
•	Work with the team to deliver a sustainable, scalable system, which integrates into an existing IT infrastructure
•	Long-term perspective: Obtain a leading role ('product owner'), incl. end-to-end responsibility for the entire system and other developer team members

Key requirements: 
•	Proficiency in required programming languages/frameworks (incl. Amazon EC2, Python)
•	Experience with running a professional local working environment, as this is a purely remote role
(in particular: experience with IDEs such as PyCharm, VisualStudio, setting up and managing virtual environments, collaboration via GitHub)
•	Strong understanding of end-to-end workflow/process management for the design phase 
(e.g., define scope of trading system, anticipate exceptions) 
•	Very high attention to data quality and detail (including checks, auditing, etc.)
•	Strong on-the-fly documentation skills (e.g., Python typing, pydantic, docstrings) 
•	High willingness to learn and explore alternative paths for challenging problems, together with the team
•	Proficiency in English language

What we offer:
•	Work with a highly motivated team, including the co-founders who are fully dedicated to making this a success
•	High degree of autonomy/independence – you can do much of the work remotely and set define your own schedule (within reasonable bounds)
•	Work with an analytically very strong team – both on business and on technology side – allowing you to bring in your own ideas and have an impact on the direction of the company
•	Long-term project with potential option to take a leading role in our growing team
