Principal Engineer

We're at a pivotal moment for both Tibber and the planet. When joining Tibber, you won’t just help scale a forward-thinking tech company – you’ll contribute to a real shift in how people consume electricity. With millions of smart devices connected to the Tibber platform (like electric vehicles and smart thermostats), we have one of the most unique portfolios trading energy on the market.

We’re looking for a Principal Engineer to join us in making the energy transition happen – maybe that’s you?

Job Mission

As our Principal Engineer, you'll report to our VP of Engineering and join our engineering org of ~80 people. 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.

What you'll do ✅

• You will 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, working in close collaboration with senior staff and staff engineers to design and evolve these systems.
  

• You will set technical vision, standards, and best practices across domain teams, partnering with senior staff and staff engineers to drive engineering excellence and operational resilience.
  

• You will partner closely with product leaders and executive stakeholders to align long-term technical roadmaps with business objectives.
  

• You will evaluate emerging technologies, prototype novel concepts, and guide strategic tech-stack decisions to keep Tibber ahead of market shifts.
  

• You will mentor and empower senior engineering talent, elevating technical craft, architecture design capabilities, and problem-solving skills throughout the company.
  

• You will diagnose and solve systemic, high-impact architectural bottlenecks, ensuring seamless integration across energy trading, IoT, and user-facing platforms.
  

• You will champion platform reliability, security, and developer efficiency, removing technical friction for autonomous engineering teams.

What we're looking for⚡

You are motivated by impact and know how to turn strategy into execution. You're used to fast-paced environments and thrive when given clear goals and high accountability. We believe you'll thrive here if you:

• Have demonstrable experience as a Principal, Staff, or Chief Engineer designing and operating mission-critical distributed systems at scale.
  

• Possess deep expertise in modern cloud architectures, event-driven microservices, high-throughput IoT streaming pipelines, or energy tech infrastructures.
  

• Demonstrate 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.
  

• Are passionate about green technology, sustainable energy transition, and creating products that make a tangible environmental impact.
  

• You will set the bar for how we build with AI agents, and shape how the rest of engineering adopts new AI-driven ways of working

Tibber exists to drive energy independence - away from fossil dependency. Our tech helps hundreds of thousands of households shift their electricity consumption to more sustainable and affordable hours - from electric vehicles to smart thermostats, all connected to the Tibber platform. We strengthen the resilience of the grid. Not in theory. In everyday life.

We win, fail, and grow together, staying curious and pushing for better every day. AI is shaping how we work - and we're on a journey to make it central to everything we do. The further we go, the more our Tibberinos matter - and yes, that's what we call ourselves!
