What will I be doing?
As a Staff Software Engineer in Enterprise Architecture, you will lead innovation on some of Kaluza’s most complex and large-scale solutions. You will influence technical strategy across multiple teams and contribute to a scalable, global platform.
Your impact will primarily be 'hands-off', focusing on architectural standards and technical leadership; however, you may occasionally embed into teams to dive into code-level design or build critical proofs-of-concept.
About You
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, train and guide senior engineers.
Lead technical audits and decision-making with confidence.
Deliver results, influence diverse audiences, and orchestrate cross-functional solutions spanning multiple product features.
Engage effectively with both technical teams and senior technology 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:
Demonstrable experience as Staff Engineer designing and delivering 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 in developing and embedding software standards across multiple teams.
Experience in adapting to significant changes in ways of working.
Ability to ramp up rapidly in new domains and technologies.
