About the role:

We are looking for a Senior Full-stack (Python/React) Developer with solid knowledge in Python, Typescript, and React to join our project with General Catalyst, a renowned venture capital firm based in the US, and take part in the solution architecture processes.

About the project:

The client is a famous venture capital firm running the fund using Salesforce as the master data repository and Google Drive for document storage. Ranging from Excel to external commercial tools and custom-built user-facing apps, different departments use multiple siloed systems for data management.

The major challenge is the suboptimal time to make the final decision as analysts can’t rely on the existing data due to possible human errors and complicated data management. The solution is to build a unified data platform that will be integrated with Salesforce and other existing systems to efficiently transform financial, legal, and ops data to data marts that are ready for interaction and comprehensive visualization with BI tools on web and mobile platforms.

Who are we looking for?

Skills & Experience:

  • 4+ years of experience in the full software development life-cycle and knowledge of Python, Typescript, and React;
  • Proficiency with Python;
  • Experience with modern JavaScript frameworks;
  • Experience with relational and distributed databases (including internals, e.g., PostgreSQL, MySQL, Cassandra, etc.);
  • Proven ability for high-quality delivery;
  • Strong interest in new technologies and willingness to learn them;
  • Experienced with GCP Cloud technologies; 
  • Experience in the implementation of REST API;
  • Experience in writing tests (the whole test pyramid: unit/integration/end-to-end);
  • Full-stack development experience on high-scale systems;
  • Solid Computer Science background;
  • Product-focused team player mindset. 

Nice to have:

  • Other front-end framework experience is a plus; 
  • Experience in designing and developing RESTful API is a plus; 
  • Database optimization;
  • Basic knowledge of data engineering.


  • Take part in the solution architecture processes;
  • Maintain high standards in software quality within the team by establishing good practices and habits;
  • Ensure the goals are met and safeguard the quality of the code via a standard code review process;
  • Work according to the SCRUM process: biweekly sprints, demos, retrospectives, planning meetings.

  • Hybrid work;
  • Company equipment provision;


  • Maternity and paternity leaves;
