• An SRE mindset: You care deeply about what happens after your code goes live, with a strong focus on maintaining and improving production services.
• Great communication: You are comfortable "working out loud" (WOL) and can confidently explain technical concepts to non-technical folks.
• Quality first: Experience with Test-Driven Development (TDD) and an openness to pair programming when tackling complex problems.
• AI-Assisted Development: You are comfortable using AI coding assistants and LLMs to accelerate your daily workflow, from scaffolding code and writing tests to debugging complex issues.
• AWS Cloud Services: Hands-on experience with specific Amazon Web Services, including DynamoDB, SNS, SQS, and S3.
