Role
Who you are
- TypeScript Expertise: Strong professional experience building scalable, production-grade applications using TypeScript and Node.js, including on AWS Serverless architectures (Lambda, API Gateway, DynamoDB) and event-driven systems such as Kafka
- AI Mindset: You think about AI as a practical engineering tool — curious about what’s possible, focused on what’s production-ready, and motivated to bring colleagues along with you
- Problem-Solving Mindset: A track record of creative problem-solving and delivering team-level technical expertise on complex application workflows
- Agile Practices: A solid grasp of CI/CD pipelines, software development fundamentals, and Agile/Lean methodologies
- Collaborative Communicator: Excellent communication skills and a genuine enjoyment of cross-functional teamwork, including explaining technical concepts to non-technical stakeholders
- We understand some people may not apply for jobs unless they tick every box. But if you're excited about joining us and think you have some of what we're looking for, even if you're not 100% sure, we'd still love to hear from you
Desirable
- LLM Integration Experience: Hands-on experience integrating large language models into production applications, whether via APIs (e.g., OpenAI, Anthropic, AWS Bedrock) or open-source models, with a solid understanding of prompt engineering, context management, and evaluation
- AI Tooling Advocacy: A track record of introducing AI-assisted developer tooling and workflows (e.g., Copilot, Cursor, Claude or similar) into a team and upskilling colleagues, not just using it personally
- Energy or Enterprise Domain Knowledge: Background working with large enterprise applications, specifically involving billing, ledger tooling, payments integration, or energy grid/supply data
- Client-Facing Awareness: Previous experience working on consulting, software-as-a-service (SaaS) onboarding, or client-delivery technical projects
What the job involves
- Team: Client Engineering
- Reporting To: Software Engineering Manager
- Hands-on Execution: Write clean, well-tested, and maintainable TypeScript to build and extend Kaluza’s platform for major clients including ENGIE, taking ownership of features from conception to deployment
- Cloud-Native Development: Build, deploy, and maintain highly scalable applications on AWS Serverless (e.g., Lambda, API Gateway, DynamoDB) and help design event-driven microservices with real-time data streaming via Kafka
- AI Integration: Identify and implement opportunities to embed AI into Kaluza’s platform and software development life-cycle - LLM-powered automation, intelligent decision support, and AI-assisted workflows. Act as an AI knowledge carrier, sharing learnings across teams and helping build a culture of AI-informed engineering
- Technical Quality & Mentorship: Champion engineering best practices through thorough code reviews and upskilling junior engineers on TypeScript, serverless, and AI development patterns
- Team Collaboration: Collaborate closely with your team, Product Managers, and Engineering Managers to refine features, estimate tasks, and deliver value predictably
Our take
The energy landscape is one of the most dynamic and fast-evolving sectors in the world. More and more energy retailers are looking to move further toward digitisation and reap the benefits of modern technology in an increasingly connected world. But many are struggling with the transition, held back by legacy operating systems which slow them down, drain resources, and hamper innovation.
This is where Kaluza comes in. An ecosystem of platforms whose services range from energy billing to smart electric vehicle charging, Its real-time cloud platforms transform supplier operations, reducing the cost to serve and boosting customer engagement. Essentially, its platform is aimed at helping businesses streamline their operations, saving them time, effort, and money which can be better invested elsewhere.
Kaluza is riding the momentum of a growing desire for sustainable business and services. Its program relating to electric car charging, for example, will be able to capitalise on huge new demand in that sector - over 100,000 electric cars are already on the roads in the UK, and Bloomberg New Energy Finance has predicted that electric cars will account for over 50% of new global car sales by 2040. As the globe moves further towards sustainable use of energy in the coming years, Kaluza could be very well positioned to capitalise.
