How to Apply for Lead Cloud Engineer

at Mill

🏢 About Mill

Mill is revolutionizing home waste management with a mission to create a cleaner, greener future by making it easy for households to reduce their environmental impact. As a startup focused on sustainability, you'll have the opportunity to work on impactful technology that directly contributes to solving real-world environmental challenges.

About This Role

As the Lead Cloud Engineer, you will own the end-to-end technical delivery of cloud infrastructure and applications that power Mill's web, mobile, and data pipelines. This role is critical to scaling their IoT-enabled waste management solution, ensuring reliability and performance as the company grows.

💡 A Day in the Life

Your day might start with a stand-up to align with product and data teams, then dive into designing a new Kinesis stream to handle increased IoT device data. You'll review pull requests for infrastructure code, monitor system metrics, and mentor junior engineers on best practices for serverless deployments.

🎯 Who Mill Is Looking For

  • Experienced with AWS IoT services (e.g., IoT Core, Greengrass) and building real-time data pipelines with Kinesis or similar streaming tools.
  • Deep knowledge of Infrastructure as Code using AWS CDK (or equivalent) and serverless architectures (Lambda, API Gateway).
  • Strong Python skills with a track record of designing scalable APIs and implementing CI/CD pipelines.
  • A proactive communicator who champions observability (metrics, logging, tracing) and takes ownership of system reliability.

📝 Tips for Applying to Mill

1

Highlight any experience with IoT devices or edge computing in your resume, even if from side projects or hackathons.

2

Quantify your impact: e.g., 'Reduced API latency by 30%' or 'Managed infrastructure serving 100k+ devices.'

3

Mention specific AWS services you've used (IoT Core, Kinesis, Lambda, CDK) in your work experience.

4

Include a link to your GitHub or a portfolio showcasing IaC projects or serverless architectures.

5

Tailor your cover letter to mention Mill's mission and how your cloud skills can help scale waste management technology.
