Job Description

About this role

You 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.

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 QuestDB database.
• We use Kubernetes for orchestration hosted on Oracle Cloud.
• We use Temporal for orchestrating long-running and distributed workflows.
• We use Kafka for event-driven messaging and real-time data streaming.
• 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.

Your tasks

• Build the backend of an application that will potentially help millions of developers and companies in the open source ecosystem
• Develop a lean and scalable architecture capable of handling billions of data points.
• Lead your own projects
• Design, develop, and optimize our backend architecture for high-performance and scalability.
• Own and refine database performance, ensuring efficient indexing, partitioning, caching, and query execution.
• Support in managing our infrastructure
• Work closely with the whole development team on the technical big picture, and contribute to strategic and company-wide decisions with the entire team.
  
  

Qualifications

• 5+ years of professional experience working with backend technologies.
• Proficiency in Node.js, Kafka, SQL, and Kubernetes. Experience with ClickHouse and PostgreSQL, or time series databases is an advantage
• Deep expertise in SQL and database optimization, including query tuning, indexing strategies, and schema design for large datasets.
• Strong knowledge of big data application scaling and distributed system design.
• Professional experience with Snowflake or other data warehouses. Knowledge of DBT is an advantage.
• A strong team player, willing to put on many hats and contribute towards the team's goals.
