VP Software Engineering

Green Fusion is a 100-person climate tech company optimizing heating systems at scale across Germany, with expansion into France. We connect to building infrastructure via proprietary hardware, collect real-time data, and deliver energy savings through algorithmic optimization. We're shifting from fast early-stage execution to a structured, product-led engineering org - and need a leader to make that happen. You'll partner closely with our CTO, CPO & CEngO to professionalize and unify our technology organization. This is a hands-on role with clear decision-making authority over engineering processes, standards, and team structure. What You'll Own Unify delivery across 4 cross-functional product teams and functional/platform teams (~35 engineers, designers, data scientists, and system engineers) Mentor and develop first time leaders Establish engineering standards: introduce consistent development processes, quality gates, and clear boundaries between discovery/prototyping and delivery Drive tech-roadmap discipline, increase alignment between engineering work and product priorities, reducing unplanned POCs and side initiatives Tackle tech debt and platform scaling, identify and sequence the highest-leverage architectural improvements (pot. in collaboration with further external support) Co-own the technology roadmap with the CTO & CPO, aligning platform and infrastructure investments with product priorities

15+ years in software engineering, with significant leadership experience - ideally as CTO or VP Engineering at startups or scale-ups Experience building engineering organizations (hiring, leveling, process design, team structure), not just managing them Strong architectural judgment across cloud infrastructure (AWS), data systems, and hardware/software integration (if necessary supported by further external resources) Comfort operating in ambiguity - able to impose structure without waiting for perfect information Understanding of AI as a key enabler in building technology organisations today People-first leadership - experienced in coaching managers, resolving cross-team friction, and raising the performance bar Fluent English required; German strongly preferred Nice to Have Experience in energy, IoT, or hardware-software integration domains Familiarity with empowered, cross-functional product teams Track record of cloud migration or platform modernization Perspective on practical AI/ML integration into engineering workflows

We are Green Fusion. We help the housing industry to make the heating and energy transition more sustainable - for a green future without compromise. By providing intelligent automation and optimization for a building's entire energy ecosystem, we reduce CO emissions where it matters most. Whether it's heat pumps, PV systems, or hybrid setups: our product serves as the interface between hardware and software, making maximum sustainability economically viable. Together, we are transforming the building sector and making efficient, climate-neutral energy the new standard. While we are still considered pioneers today, with you by our side, we will soon dominate the market! Starting in the DACH region, and then across all of Europe. You can expect a motivated, open-minded, and vibrant team that is passionate about actively shaping the energy transition and growing together.
