Senior/Middle Ruby SDE (Python/Go optional) (GH)

We are looking for strong Senior / Middle Software Development Engineers for a coding-heavy automated dependency management project at a developer platform company. The tool monitors outdated or vulnerable packages and creates pull requests to update them across multiple package ecosystems. The exact scope between the open-source tool and the platform remains to be confirmed.

Requirements:

• Strong hands-on coding and readiness to contribute from day one; practical coding ability matters more than years of experience;
• Ruby proficiency and ability to work with Go and Python;
• Confident everyday use of AI coding tools, including GitHub Copilot and agentic workflows;
• Git/GitHub workflows, including pull requests, code review and CI with GitHub Actions;
• Independent delivery, ownership of substantial work and good English for meetings, pull requests and issues.

Responsibilities:

• Contribute hands-on development to automated dependency management tooling;
• Work across languages and package ecosystems to support dependency updates;
• Collaborate through pull requests, code review and CI workflows;
• Take ownership of development tasks and ramp up quickly.

Nice to Have:

• Knowledge of package managers and ecosystems, including Bundler, npm/yarn, pip/Poetry, Go modules, Maven/Gradle, NuGet and Cargo;
• Experience with dependency management, semantic versioning and supply-chain security, including CVE/advisories;
• Docker;
• Open-source contributions, especially to relevant developer-platform or dependency-management repositories.

Working Conditions:

• Overlap: until 11 AM / 12 PM PT (Eastern Europe timezone works);
• Target start: ASAP. A couple of engineers who can start in 3-4 weeks and ramp up quickly; the rest can come in a second wave.

Locations: Poland, Croatia, Portugal, Serbia, Egypt, Amrenia, Georgia, KZ.
