About the Role

As our Principal Engineer, you will serve as the technical authority driving the overarching architecture and engineering strategy across all of Tibber. You will bridge complex domain problems, from distributed real-time IoT pipelines to energy market integration, with resilient, high-scale software systems. Your work directly enables millions of smart devices to balance power grids across Europe, unlocking new horizons in sustainable energy consumption.

Responsibilities

  • Own the overall architecture and technical strategy for low-latency, highly resilient distributed systems capable of coordinating millions of connected smart devices in real time.
  • Set technical vision, standards, and best practices across domain teams.
  • Partner closely with product leaders and executive stakeholders to align long-term technical roadmaps with business objectives.
  • Evaluate emerging technologies, prototype novel concepts, and guide strategic tech-stack decisions.
  • Mentor and empower senior engineering talent, elevating technical craft, architecture design capabilities, and problem-solving skills.
  • Diagnose and solve systemic, high-impact architectural bottlenecks, ensuring seamless integration across energy trading, IoT, and user-facing platforms.
  • Champion platform reliability, security, and developer efficiency, removing technical friction for autonomous engineering teams.
  • Set the bar for how we build with AI agents, and shape how the rest of engineering adopts new AI-driven ways of working.

Requirements

  • Motivated by impact and know how to turn strategy into execution.
  • Accustomed to fast-paced environments and thrive when given clear goals and high accountability.
  • Demonstrable experience as a Principal, Staff, or Chief Engineer designing and operating mission-critical distributed systems at scale.
  • Deep expertise in modern cloud architectures, event-driven microservices, high-throughput IoT streaming pipelines, or energy tech infrastructures.
  • Strong technical leadership and communication skills, with a track record of driving cross-functional alignment on high-stakes architecture decisions.
  • Combine long-term strategic vision with a hands-on pragmatic approach, willing to dive into code or debug complex incidents when required.
  • Passionate about green technology, sustainable energy transition, and creating products that make a tangible environmental impact.
