• Develop user-facing product features with a strong focus on usability, performance, and maintainability.
• Design and evolve Rust application logic for authentication, IPC contracts, service integrations, and real-time stream handling.
• Build and maintain streaming flows for live data, including throttling, backpressure handling, and multi-window consistency.
• Maintain secure authentication and authorization flows based on OIDC and Keycloak.
• Own and improve CI/CD workflows in GitHub Actions, including validation, coverage, packaging, signing, and release publishing.
• Support release and delivery workflows across Windows and macOS.
• Work with AWS services used in delivery and operational workflows, especially S3, IAM roles, OIDC-based access, and secrets handling.
• Improve observability through logging, metrics, runtime diagnostics, and better release visibility.
• Collaborate on application architecture, testing strategy, and engineering standards across frontend, backend, and operational concerns.

Qualifications

• A university degree in a relevant field of study (e.g. computer science, engineering, sciences, ...) or a comparable qualification.
• Extensive experience in our tech stack: React, TypeScript, Vite, Rust, GitHub Actions, AWS.
• Strong experience building production software with React and TypeScript.
• Basic Rust proficiency, or solid experience in a compiled backend or systems language with the ability to become productive in Rust quickly.

• Experience maintaining CI/CD pipelines and release workflows in GitHub Actions.
• Basic AWS knowledge relevant to software delivery and operations.
• Strong analytical thinking, both in the technical and in the product domain.
• Excellent communication skills that are clear, concise, and targeted towards your audience - engineering, product, or other stakeholders.
• A passion for well architected, testable and documented code.
• Experience improving observability through logs, metrics, and production diagnostics is a plus.
• Experience with native application packaging, updater/signing flows, and cross-platform release automation is a plus.
