Contractor Software Engineer, Integrations (Contractor)

About this roleYou will join the LFX platform team for a high-impact role in building a mission-critical application for the entire open source ecosystem. You will be part of an open-source-obsessed team where you do more than writing code: you will lead your own projects, be in contact with users, make architectural decisions, manage infrastructure, and you will always be encouraged to take the initiative.

Furthermore, at the Linux Foundation, you will be contributing to a fully open-sourced codebase. Your contributions will be public, and you will join us in building toward an open future.

The expected salary range is $50-60k based on your experience level. The position is fully remote within European time zones (CET +/- 2 hours).

Our tech stack We use a modern, lightweight tech stack to provide an enjoyable and productive development experience. The backend is built with Node.js, backed by a PostgresSQL and a time-series database. We use Kubernetes for orchestration hosted on Oracle Cloud. We use Temporal for orchestrating long-running and distributed workflows.

We use Vue.js for frontend development, with Tailwind CSS for styling. We have a philosophy of buying-over-building. We try never to reinvent the wheel and use the best open-source solution for problems that are not our core. We work with exciting, cutting-edge technologies such as LLMs, text and vector search engines, and semantic database layers. You will find the team is always excited to try new technologies.
