POSITION OVERVIEW:

We are seeking a skilled and motivated Frontend Developer to join our team, working on the next-generation implementation of Aleph (“Aleph Pro”) — OCCRP’s investigative data platform used by journalists and researchers worldwide to uncover corruption, financial crime, and abuse of power. This role is frontend-focused and will help shape the look, feel, and usability of Aleph’s new interface.
You will work closely with a project lead, engineering manager, product manager, developers, and data specialists in a highly collaborative environment. Our team works on overlapping projects and stays closely aligned through regular communication, shared planning, and joint problem-solving. In this role, you’ll design and implement a modern, intuitive, and performant frontend for Aleph Pro, contributing to both its full redesign and integration with other investigative tools. You’ll be part of rebuilding the frontend from the ground up — improving existing features and developing entirely new capabilities to support large-scale investigative work.
