How to Apply for Software Engineer - ClimateTech Startup

at Logical Buildings

🏢 About Logical Buildings

Logical Buildings is a ClimateTech startup that helps residential and commercial customers earn money and reduce their carbon footprint through two flagship products: GridRewards and SmartKit. Working here means directly contributing to the fight against climate change while helping building owners and managers save on energy costs. As a small but growing team, you'll have the opportunity to shape both technology and culture from the ground up.

About This Role

As a Software Engineer, you'll focus primarily on API development and data engineering, with some front-end and mobile work, building solutions that power energy optimization and real-time insights for buildings. Your work will directly enable users to track energy consumption, earn rewards for reducing usage, and manage building performance. You'll be instrumental in scaling a platform that makes a tangible environmental and financial impact.

💡 A Day in the Life

You might start your day with a stand-up to discuss progress on a new API endpoint for real-time energy data, then dive into coding and testing. Later, you could collaborate with the data team to optimize a TimescaleDB query, or spend time debugging a Kubernetes deployment issue. You'll also review pull requests and perhaps contribute to a front-end component for the SmartKit dashboard.

🎯 Who Logical Buildings Is Looking For

  • Proficient in Python and Django for backend development, with experience designing and implementing RESTful APIs.
  • Experienced with data engineering concepts and tools such as PostgreSQL, TimescaleDB, and message queues like Pub/Sub.
  • Familiar with cloud infrastructure (Google Cloud preferred) and container orchestration (Kubernetes, Cloud Run).
  • Comfortable contributing to front-end or mobile development when needed, and passionate about sustainability and energy efficiency.

📝 Tips for Applying to Logical Buildings

1

Highlight any experience with energy data, IoT, or sustainability-focused projects in your resume and cover letter.

2

Showcase your Python/Django expertise by linking to GitHub repos or describing specific API endpoints you've built.

3

Demonstrate familiarity with Google Cloud services (e.g., Pub/Sub, Cloud Run) and Kubernetes—mention any relevant certifications or projects.

4

Explain why you're excited about ClimateTech and Logical Buildings' mission, not just the tech stack.

5

If you have front-end or mobile experience, emphasize your ability to work across the stack, as the role includes some of that work.

✉️ What to Emphasize in Your Cover Letter

['Your passion for climate change and how your technical skills can contribute to reducing carbon footprints.', "Specific examples of backend or data engineering projects you've led, especially those involving real-time data or large-scale systems.", "Your experience with the exact tech stack (Python, Django, PostgreSQL, TimescaleDB, Kubernetes, GCP) and how you've used it to solve problems.", 'Your ability to thrive in a small, fast-paced startup environment and willingness to contribute beyond backend work.']
