STARK is a new kind of defence technology company revolutionising the way autonomous systems are deployed across multiple domains.
We design, develop, and manufacture high-performance unmanned systems that are software-defined, mass-scalable, and cost-effective
— providing operators with a decisive edge in contested environments.
We are focused on delivering deployable, high-performance systems — not future promises. In a time of rising threats, STARK is
bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe, today
You will own the product roadmap for one of the hardest and most consequential capabilities in our autonomy stack: how our
platforms know where they are when GPS isn't available or can't be trusted. You won't be writing the estimation filters yourself,
but you'll be translating deep technical complexity into a roadmap that ships, and making sure engineering effort lands on the
problems that matter most. Success looks like a localization capability that improves predictably, release over release, with
clear priorities that the technical team trusts.

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 energy trading portfolios on the market. We’re looking for a Product Manager to join us in making the energy transition happen – maybe that’s you? ---------------------------------------------------------------------------------------------------------------------------------- Job Mission 🚀 As a Product Manager for Energy Market, you'll lead the foundational capabilities that make it possible for Tibber to deliver electricity to customers across four markets, from supplier switching and metering data ingestion to market integrations and delivery lifecycle management. This role sits behind many customer-facing experiences. Your impact is measured in processes that work, markets that scale, and engineering teams that can move faster because someone understands the domain well enough to lead, not just coordinate. ---------------------------------------------------------------------------------------------------------------------------------- What you'll do ✅ * Lead/own the product roadmap and delivery for foundational electricity-delivery capabilities — market integrations, supplier switching, metering data ingestion, and delivery lifecycle management * Drive improvements to conversion and completion rates across onboarding and activation flows, reducing drop-off and failure rates as new signups move through market processes * Work closely with the Energy Contract PM to maintain clean boundaries between foundational delivery and commercial contract logic * Contribute to building AI-assisted solutions that reduce manual back-office work and help the team identify and prioritize the right problems faster ---------------------------------------------------------------------------------------------------------------------------------- What we're looking for⚡ You're energized by bringing clarity to complex domains — comfortable navigating regulated environments where success depends on understanding how external actors, systems, and processes interact. We believe you'll thrive here if you: * Have proven experience as a PM in a complex, regulated, multi-actor operational domain - energy, logistics, telecom, payments, or similar * Can independently map actor relationships, information flows, and regulatory constraints without leaning on engineering to explain the domain * Use data to identify where processes break down and drive measurable improvements — whether that's failure rates, completion rates, or operational efficiency * Are comfortable working with backend systems and APIs as part of your daily work * Communicate proactively — you surface blockers, share context, and keep stakeholders aligned without being prompted; especially important in a distributed team where some engineers are in Berlin and others are not * Tibber is becoming more AI-enabled and we embrace new tools and ways of working. You don't need to be an expert, but we believe you are motivated by that and excited to grow with it too ---------------------------------------------------------------------------------------------------------------------------------- 💆🏻♀️💆🏽♂️The Tibber Mindset 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, strengthening the resilience of the grid. Not in theory. In everyday life. Being on a mission to change an industry means being prepared for the unexpected. We do what others say can't be done – and we do it together. We win, fail and grow together, staying curious and pushing for better - every day. AI is shaping how we work - and we believe it's how we accelerate the energy transition. The more it becomes part of how we operate, the more our Tibberinos matter. Started by two founders in 2016. Now 300+ Tibberinos across Stockholm, Berlin, Amsterdam, Oslo and Førde. Backed by Balderton Capital, Eight Roads Ventures, Founders Fund, Summa and Schibsted. Still just getting started. Diversity of thought fuels better products. We welcome applicants of every background, identity and lived experience. Ready to be part of powering the energy transition? Apply below!
