How to Apply for Senior Site Reliability Engineer

at Uplight

🏢 About Uplight

Uplight is a clean energy software company that partners with leading utilities to manage distributed energy resources like smart thermostats, EVs, and solar panels. Their platform creates virtual power plants by aggregating these devices, directly reducing reliance on fossil fuels. Working here means contributing to the decarbonization of the grid while helping customers save money—a rare blend of environmental impact and practical engineering.

About This Role

As a Senior Site Reliability Engineer at Uplight, you'll ensure the reliability and scalability of the platform that orchestrates millions of energy devices. Your work directly impacts grid stability and the adoption of clean energy technologies. You'll collaborate with product and engineering teams to design resilient systems, automate operations, and respond to incidents that affect real-world energy usage.

💡 A Day in the Life

A typical day might start with a standup discussing ongoing incidents or reliability metrics, followed by working on automating deployment pipelines or tuning monitoring alerts. You might collaborate with a product team to set SLOs for a new feature, then spend time on-call responding to a real-time data latency issue. Afternoons could involve writing postmortems or mentoring junior engineers in SRE best practices.

🎯 Who Uplight Is Looking For

  • Experienced with cloud-native architectures (AWS/GCP) and infrastructure-as-code (Terraform, Kubernetes) in production environments.
  • Skilled in observability tools (Datadog, Prometheus, Grafana) and incident response, with a focus on automation and reducing toil.
  • Passionate about clean energy and sustainability, with a desire to apply SRE practices to accelerate the energy transition.
  • Strong communicator who can work cross-functionally with product and engineering to define SLOs and error budgets.

📝 Tips for Applying to Uplight

1

Highlight any experience with IoT or distributed energy resource management, even if not directly in energy—Uplight values domain-relevant but transferable skills.

2

In your resume, emphasize specific reliability improvements you've made (e.g., reduced p99 latency by X%, automated Y% of incident response).

3

Tailor your cover letter to mention Uplight's mission of 'creating clean energy capacity' and how your SRE background can help achieve that.

4

If you have experience with real-time data pipelines or event-driven architectures (e.g., Kafka), be sure to mention it, as Uplight handles streaming device data.

5

Research Uplight's recent partnerships or product launches (e.g., with major utilities) and reference them in your application to show genuine interest.

✉️ What to Emphasize in Your Cover Letter

['Your motivation for working in clean energy and how SRE directly supports grid decarbonization.', 'Concrete examples of improving system reliability, scalability, or automation in previous roles.', "Familiarity with Uplight's platform (e.g., managing DERs, virtual power plants) and how your skills align.", 'Your approach to incident management and collaboration with development teams to prioritize reliability.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read Uplight's blog or case studies about their work with utilities like AES or National Grid.
  • → Understand the concept of 'virtual power plants' and how Uplight's software enables them.
  • → Review their recent news (e.g., funding, partnerships) to show you're up-to-date with their growth.
  • → Check their engineering blog or talks on YouTube to understand their tech stack and culture.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Design a system to handle real-time telemetry from millions of IoT devices with high availability and low latency.
2 How would you define SLOs and error budgets for a platform that controls energy devices?
3 Describe a time you automated a manual operational process and the impact on reliability.
4 How do you approach incident response for a distributed system? Walk through a past example.
5 What experience do you have with Kubernetes and infrastructure-as-code in production? How do you ensure security and compliance?

⚠️ Common Mistakes to Avoid

  • Don't focus solely on infrastructure without mentioning reliability engineering principles (SLOs, error budgets, blameless postmortems).
  • Avoid generic statements about 'passion for sustainability' without connecting it to your technical work.
  • Don't ignore the domain—failing to mention any understanding of energy or IoT could signal disinterest.
