Tooling Engineer – Clinical Data Team

Internal Developer Tools | CLI | Python | Shell

For an international organization operating in Clinical Data Management, we are looking for a Tooling Engineer to join a small, technically driven team building internal developer tools.
This role is about improving developers’ daily work through well-designed scripts, libraries, and CLI utilities.

You won’t be building customer-facing products.
You’ll be building tools for the people who build everything else.

Role Summary

You will design, maintain, and evolve workstation-level tooling that supports clinical data processing workflows.

Work split:

• ~50% maintenance and refactoring of existing tools
• ~50% greenfield development of new tools

Occasionally, you may support light operational tasks (e.g. job scheduling or publishing outputs), but this is not an ops role.

 What You’ll Do

• Refactor and harden existing code (reliability, edge cases, legacy cleanup)
• Build new tools from team specifications:
  • CLI utilities
  • Python libraries
  • Automation scripts
• Participate actively in code reviews — both giving and receiving feedback
• Communicate proactively: explain what you’ve built, share insights, keep the team aligned
• Work in a CLI-first environment

? Working Conditions

• Location: Poland
• Work model: Hybrid — 3 days per week onsite (Warsaw office)
• Start date: ASAP
• Collaboration: daily standups, light weekly syncs, async-first communication
• Autonomy: high — you decide how to solve problems; the team decides what to prioritize

Must Have

• Strong shell scripting skills (Bash, Zsh, or similar)
• Willingness to learn Nushell (or existing experience)
• Solid Python proficiency (data processing with Polars)
• Experience refactoring and maintaining existing codebases
• Good working knowledge of Git (we also use Jujutsu)
• Cross-platform awareness (macOS & Windows)
• Ability to write clean, readable, well-commented code
• Fluent English (written and spoken)

Nice to Have

• Functional programming mindset (immutability, composition, declarative patterns)
• Experience building internal developer tools
• Familiarity with chezmoi or similar configuration management tools
• Exposure to AI-assisted development (Copilot, ChatGPT, Claude)
• Ability to exit Vim without Googling ?

Who You Are

• Autonomous but communicative — you own your work without disappearing
• Curious and adaptable — comfortable learning new tools and ecosystems
• Quality-oriented — you care about maintainability, not just “does it work”
• Pragmatic — you adapt best practices to context
• Collaborative — you treat code review as a conversation, not gatekeeping
