• System Design Competency: Expertise in architectural decision-making and the ability to design systems that balance complexity with maintainability.

What we avoid

• Dependency on External Teams: Candidates who require extensive support from other teams or external resources to deliver working software would not a be great fit.
• Beyond Standard Agile: Ideal candidates are those who explore beyond conventional sprints and ceremonies, leveraging whatever methodologies best fit the team and project to drive quality and impact.

Soft skills

• Strong Written Communication: Skilled at long-form communication, including detailed technical documentation and decision-making rationale. Comfortable reading and contributing actively to comprehensive documentation.
• Autonomous and Pragmatic: Capable of independently framing problems, designing solutions, and executing tasks. Pragmatic in balancing technical idealism with real-world constraints.
