How to Apply for People & Finance Systems Developer

at Kaluza

🏢 About Kaluza

Kaluza is an intelligent software platform that empowers energy suppliers to drive decarbonisation. By joining Kaluza, you'll work at the intersection of cutting-edge AI and sustainable energy, contributing to a mission that directly tackles climate change while building transformative internal tools.

About This Role

As the People & Finance Systems Developer, you'll design and deploy AI workflows using modern LLMs like Anthropic and Gemini to revolutionize internal People and Finance operations. You'll integrate these AI capabilities into tools like Workday and Slack, collaborating directly with stakeholders to build prototypes and iterate rapidly.

💡 A Day in the Life

Your day might start with a standup with the People team to discuss a new request for automating expense report approvals. You'll then prototype a workflow using Anthropic's Claude API to extract data from receipts in Slack, test it with a few users, and iterate based on feedback. Later, you'll document your approach and ensure compliance with data privacy standards before deploying.

🎯 Who Kaluza Is Looking For

  • A developer with 1-2 years of commercial experience who is equally comfortable coding and connecting systems via REST APIs.
  • Hands-on experience with LLM APIs (Anthropic, OpenAI, or Gemini) beyond just calling them—ideally you've built a prototype or workflow.
  • Strong communication skills to work directly with non-technical stakeholders and translate their needs into AI-powered solutions.
  • A passion for responsible AI use, with an understanding of data privacy and ethical considerations in deploying LLMs.

📝 Tips for Applying to Kaluza

1

Highlight any projects where you integrated LLMs into business tools (e.g., Slack bot, Jira automation) even if it was a side project.

2

Mention specific experience with Workday, Greenhouse, or similar HR/Finance systems; if you lack that, emphasize API integration skills.

3

Showcase your ability to prototype quickly—include a link to a GitHub repo or a short video demo of an AI workflow you built.

4

Tailor your cover letter to Kaluza's mission: connect your technical skills to the broader goal of decarbonisation.

5

Research Kaluza's product and mention how your work on internal systems directly supports their external customer-facing platform.

✉️ What to Emphasize in Your Cover Letter

['Your experience with LLM APIs and building AI workflows that solve real business problems.', 'Your ability to collaborate with stakeholders to understand problems and iterate on feedback.', 'Your commitment to responsible AI and data privacy, especially in People and Finance contexts.', 'Your excitement about contributing to a company that fights climate change through technology.']

  • → Read Kaluza's blog and press releases to understand their platform and recent product updates.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk me through a time you integrated an AI model into an existing system via API. What challenges did you face?
2 How would you approach building a Slack bot that answers employee questions about benefits using an LLM?
3 Explain how you ensure data privacy when using external LLM APIs with sensitive HR data.
4 Describe a prototype you built quickly. How did you gather feedback and iterate?
5 What experience do you have with Workday, Greenhouse, or similar systems? How would you connect them via APIs?

⚠️ Common Mistakes to Avoid

  • Don't focus solely on AI/LLMs without showing you can handle the integration and systems side (APIs, Workday).
  • Avoid generic statements about 'passion for technology'—tie everything back to Kaluza's mission and this specific role.
  • Don't neglect the People/Finance domain: failing to mention any understanding of HR or financial processes can hurt your application.
