How to Apply for Senior DevOps Engineer

at TeraWatt Infrastructure

🏢 About TeraWatt Infrastructure

TeraWatt Infrastructure is at the forefront of the EV revolution, building the critical charging infrastructure needed to decarbonize fleet transportation. Their mission to accelerate fleet electrification offers a unique opportunity to work on impactful, real-world environmental solutions while solving complex engineering challenges at scale.

About This Role

As a Senior DevOps Engineer, you'll architect and manage the cloud infrastructure that powers TeraWatt's EV charging platform, ensuring high availability and scalability. Your work on CI/CD pipelines, Kubernetes clusters, and ML infrastructure will directly enable faster feature delivery and data-driven insights, accelerating the transition to electric fleets.

💡 A Day in the Life

Your day might start with a stand-up to coordinate with engineering teams, followed by reviewing pull requests for infrastructure changes. You could spend the morning troubleshooting a CI/CD pipeline failure, then shift to designing a Terraform module for a new microservice. After lunch, you might collaborate with data scientists to optimize Kubernetes resources for a model training job, and end the day by monitoring Grafana dashboards to ensure system health.

🎯 Who TeraWatt Infrastructure Is Looking For

  • A hands-on engineer with 5+ years of DevOps experience, deeply proficient in AWS, Terraform, and Kubernetes (EKS), who has built production systems at scale.
  • Someone who treats infrastructure as code and security as a first-class concern, with a track record of implementing robust CI/CD pipelines (GitHub Actions) and observability stacks (OpenTelemetry, Grafana).
  • A Python or NodeJS developer who can contribute to automation scripts and tooling, and has experience managing databases like PostgreSQL or MongoDB in production.
  • A collaborative problem-solver who enjoys working closely with engineering teams to streamline deployments and support ML workloads.

📝 Tips for Applying to TeraWatt Infrastructure

1

Highlight specific projects where you used Terraform to manage multi-environment AWS infrastructure, especially if you've worked with EKS and GitHub Actions.

2

Quantify your impact: mention uptime improvements, deployment frequency increases, or cost reductions achieved through your infrastructure changes.

3

Demonstrate security expertise by describing how you've implemented network security, IAM policies, or secrets management in a cloud environment.

4

Show your experience with observability: describe a time you set up OpenTelemetry or Grafana dashboards to troubleshoot production issues.

5

Tailor your resume to include keywords like 'EKS', 'GitHub Actions', 'Terraform', 'OpenTelemetry', and 'ML infrastructure' to pass ATS filters.

✉️ What to Emphasize in Your Cover Letter

['Your passion for sustainability and how your DevOps skills can directly contribute to reducing carbon emissions through EV charging infrastructure.', 'Concrete examples of building resilient, scalable cloud systems using Terraform and Kubernetes, with a focus on high availability.', "Your experience enabling engineering velocity through CI/CD pipelines (GitHub Actions) and how you've supported ML model deployment.", 'Your commitment to security best practices across the stack, from cloud networking to application secrets management.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Explore TeraWatt's website and recent press releases to understand their current partnerships and scale of EV charging deployments.
  • → Read about the challenges of fleet electrification, such as grid capacity and charging station reliability, to contextualize the infrastructure needs.
  • → Familiarize yourself with TeraWatt's technology stack mentioned in job postings or engineering blogs (if any) to align your experience.
  • → Check LinkedIn for current employees in DevOps or engineering roles to understand team culture and priorities.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 How would you design a highly available, multi-region AWS infrastructure for an EV charging platform using Terraform and EKS?
2 Describe a challenging CI/CD pipeline you built with GitHub Actions, including how you handled secrets, testing, and rollbacks.
3 How do you approach security in a cloud-native environment? Give examples of network policies, IAM roles, or pod security you've implemented.
4 Walk us through how you would set up observability for a Kubernetes cluster handling real-time charging data, using OpenTelemetry and Grafana.
5 How have you supported machine learning workloads in production? Discuss infrastructure considerations for model training and deployment.

⚠️ Common Mistakes to Avoid

  • Submitting a generic resume that doesn't mention AWS, Terraform, Kubernetes, or GitHub Actions, as these are core requirements.
  • Overlooking the ML infrastructure aspect: failing to discuss any experience with ML pipelines or model deployment could be a missed opportunity.
  • Neglecting security: not emphasizing security best practices in your application or interview can signal a lack of attention to critical requirements.
