How to Apply for Software Engineer (TypeScript)

at Centrica Energy

🏢 About Centrica Energy

Centrica Energy is at the forefront of the global green energy transition, offering a unique blend of energy trading and technology. Working here means contributing directly to sustainable and predictable energy solutions, with a mission-driven culture that values innovation and environmental impact.

About This Role

As a Software Engineer (TypeScript) on the backend team, you'll build and evolve critical SaaS platforms that enable efficient energy trading. Your work on serverless and event-driven architectures will directly support the company's goal of making green energy more accessible and reliable.

💡 A Day in the Life

You'll start by reviewing the team's Kanban board and stand-up, then dive into coding a new serverless function for trade validation. After lunch, you might pair with a Product Owner to refine requirements, then deploy a Terraform change to staging. The day ends with code review and monitoring dashboards for production issues.

3

Showcase any work with event-driven patterns (e.g., using Kafka, SQS, or EventBridge) and how they solved real-world scalability issues.

4

If you have experience in energy trading or commodities, mention it—even if tangential—as domain knowledge is a plus.

5

Prepare a concise portfolio or GitHub repo with a TypeScript/Node.js project that demonstrates clean architecture and testing.

⚠️ Common Mistakes to Avoid

  • Don't overemphasize frontend or mobile experience; this is a backend role focused on TypeScript/Node.js and cloud.
  • Avoid generic statements about 'passion for technology' without connecting it to energy or sustainability.
  • Don't neglect to mention your experience with Infrastructure as Code—it's a key requirement and often overlooked.
