At this time, we are not able to offer visa sponsorship for this role. We are committed to building a diverse, global team and our sponsorship policy is evaluated on a role-by-role basis. We encourage you to keep an eye on our careers site to stay informed about future opportunities where we are able to offer visa sponsorship. Kaluza is the Energy Intelligence Platform, turning energy complexity into seamless coordination. We help energy companies overcome today’s challenges while accelerating the shift to a clean, electrified future. Our platform orchestrates millions of real-time decisions across homes, devices, markets and grids.

What will I be doing? As a Principal Software Engineer at Kaluza, you will be the leading technical authority for a major global product area comprising multiple modules. You will lead innovation on some of the most complex, ambiguous, and large-scale solutions, aligning them with target architecture standards and contributing to the creation of a scalable platform. You’ll have a broad sphere of influence, enabling multiple teams and serving as a strategic partner to our architecture leadership team and our community of principal and staff engineers. Your impact will come mostly from 'hands-off' work; you’ll not be expected to write code day-to-day. But for some challenges, you may need to dive into code-level design or help build a proof-of-concept. About You Ideally you’ll have/be • Architect modern distributed, cloud-based systems applying modern architecture and engineering practices in an enterprise software environment. • Shape and influence technical vision and product roadmaps to align with business goals. • Provide hands-on leadership, making appropriate technical choices to satisfy requirements. • Mentor and guide engineers in delivering autonomous, loosely coupled distributed systems with proven architectural principles and patterns. • Lead technical due diligence and make high-stakes decisions with confidence. • Deliver results, influence diverse audiences, and orchestrate cross-functional solutions spanning multiple product features. • Engage effectively with both technical teams and executive leaders. • Work independently and collaboratively, bringing strong opinions while respecting others, communicating openly, and maintaining self-awareness with a continuous growth mindset. What will set you apart • Experience enabling engineering teams to use AI and delivering AI/ML powered solutions. • Demonstrable experience in architecting solutions in complex business domains, particularly interface design and data modelling, ideally with experience in AWS and API design. • Proven track record delivering global B2B2C SaaS (energy or other mission‑critical industries). • Success driving adoption of modern engineering practices (e.g. DevOps, CI/CD). • Experience leading teams through significant changes in ways of working. • Ability to ramp up rapidly in new domains and technologies. Where you'll work We offer flexible working, with an expectation of 3 days a week in the office. This gives us the best of both: real time together to collaborate and build relat
