How to Apply for Scala Engineer II - API Platform Team
at Kaluza
🏢 About Kaluza
Kaluza stands out as a technology company uniquely focused on the energy sector, specifically empowering energy suppliers with intelligent software to drive decarbonisation. Their mission combines technical innovation with environmental impact, offering engineers the chance to build scalable platforms that directly contribute to a sustainable future. Working at Kaluza means joining a company where software has a clear, positive real-world effect on climate change.
About This Role
As a Scala Engineer II on the API Platform Team, you'll be responsible for developing and supporting the KaPI and KEG products, balancing discovery tasks, tech debt, and core delivery tickets. This role is impactful because you'll be building the foundational APIs that enable energy suppliers to operate more efficiently and sustainably. You'll also participate in in-hours support rotations and contribute to team ceremonies like planning, stand-ups, and retrospectives.
💡 A Day in the Life
A typical day might start with a team stand-up to discuss progress on KaPI or KEG tickets, followed by focused work on a mix of discovery tasks, tech debt, or core delivery items. You could spend time pairing with a colleague on a complex problem, then shift to reviewing CI/CD pipeline improvements or preparing for in-hours support as part of the team rota. The day often wraps up with backlog refinement or a retro to continuously improve team processes.
🚀 Application Tools
🎯 Who Kaluza Is Looking For
- Has hands-on backend or full-stack development experience with Scala, ideally in building and maintaining API platforms or similar distributed systems.
- Demonstrates proficiency with a broad toolset including CI/CD pipelines and Infrastructure as Code (e.g., using tools like Terraform, Jenkins, or Kubernetes), showing they can manage the full development lifecycle.
- Provides concrete examples of independently solving complex technical problems while also collaborating effectively in pair programming or problem-solving sessions.
- Shows genuine enthusiasm for learning new technologies and domains, particularly in the energy or decarbonisation space, aligning with Kaluza's mission-driven work.
📝 Tips for Applying to Kaluza
Tailor your resume to highlight specific Scala projects where you built or maintained APIs, and mention any experience with API platforms or similar products.
Include examples in your application that demonstrate your experience with CI/CD pipelines and Infrastructure as Code, as these are explicitly mentioned in the requirements.
Research Kaluza's KaPI and KEG products (if publicly available) and mention how your skills align with developing or supporting such platforms in your cover letter.
Prepare to discuss a time you proactively solved a technical problem independently, as well as an example of effective pair programming or collaboration.
Emphasize any interest or experience in the energy sector or decarbonisation projects, as this aligns with Kaluza's mission and could set you apart.
✉️ What to Emphasize in Your Cover Letter

💬 Prepare for These Interview Topics
Based on this role, you may be asked about:
⚠️ Common Mistakes to Avoid
- Submitting a generic application without tailoring it to highlight Scala experience or API platform development, as this role is highly specific.
- Failing to provide evidence of hands-on work with CI/CD pipelines or Infrastructure as Code, which are explicit requirements in the job description.
- Overlooking Kaluza's mission-driven focus on decarbonisation; not showing interest in the energy sector or sustainability could make you seem misaligned with the company's goals.
