Pillar; Barcelona; On-site; EUR 100,000 - 120,000; Full time

Job summary

Pillar, founded in 2025, is building the financial operating system for construction. Today we are 90+ people, serving 1000+ customers and expanding internationally.

We seek a Head of Product who started as an engineer, loves guiding a product team, and wants to grow a team of product managers. The mission is to make the roadmap a company-wide tool: lead PMs, own product plans, measure and ship, aligning design, engineering and product with our CTO.

Qualifications

• Engineers at heart who lead with data and care about people.
• You started as an engineer and can talk architecture, estimates and trade-offs with engineering as a peer.
• You have experience in B2B SaaS, with complex workflows and multiple user personas.
• You have lived a 1 to 10 phase: scaling a product, its roadmap and its team after product-market fit.
• You have managed product managers directly and love seeing people grow.
• You are data-driven for real: you define metrics, build dashboards and write your own SQL.
• You have a track record of predictable delivery across multiple teams, and of rituals people found useful.
• You give clear and kind feedback and bring calm and clarity when things get messy.
• You are AI-native: AI is already part of how you work and how you build.
• Fluent English. Based in Barcelona or happy to relocate.
• Nice to have: PostHog and Linear, AI or LLM-powered features, ERP, fintech or vertical SaaS, construction, Italian or Spanish.

Responsibilities

• Lead and grow our product managers, who report directly to you.
• Define the KPIs for every product module and show how they ladder up to company goals.
• Build and look after the product dashboards the whole company relies on: adoption, usage, performance and CSAT.
• Follow the product teams' goals closely, spot gaps early and work with the teams on how to close them.
• Own what the product organisation ships: scope, quality and predictability.
• Deliver the roadmap on time, raising risks and trade-offs before a deadline slips.
• Run the rituals that keep design, engineering and product aligned, and change them when they stop helping.
