Growth Senior Product Designer

Hello! 👋

This is Lara from Factorial and I am seeking a Senior Product Designer for the Product Growth Team.

At Factorial, we’re building the leading Business Management platform for SMBs.

Our software helps companies manage HR, Finance, and Operations — everything from payroll to employee performance to expenses — all in one place.

We’re one of Europe’s fastest-growing SaaS companies, with 1M+ users, 1,400 employees, and presence in 7 markets, backed by top-tier investors and proudly headquartered in sunny Barcelona.

Our next chapter? Reaching €1B ARR within the next three years.

To get there, we need to make Factorial scale itself — and that’s where the Product Growth team comes in. Ready to be part of the challenge? 🚀 Read below! 👀

💪 Your mission

At Factorial, Product Growth means driving measurable impact: not vanity metrics, but actual revenue.

Our focus is now on customer expansion and self-serve experiences: designing journeys that help users discover, upgrade, and get more value from Factorial without needing hand-holding. Next, we’ll take on activation and onboarding, helping customers reach their first “aha!” moment faster than ever.

And this is just the start. Our long-term vision? To sell to thousands of customers purely through the product — transforming Factorial into a Product-Led Growth (PLG) engine.

You’ll join our Product Growth team, reporting directly to Lara (yes, the same Lara writing this job post 😉), team’s lead and Product Manager.

You’ll partner with David, our Growth Product Designer, working hand-in-hand on some projects and owning others independently.

You’ll collaborate closely with Pablo, our Engineering Manager, and our dev dream team: Amalia, Chloe, and Ruben — a sharp crew who ship fast, experiment even faster, and know their metrics cold.

At the start, we’ll move as one unified team, combining forces across design, product, and engineering. As we scale, we’ll evolve into multiple teams — and you’ll play a key role in shaping how Product Growth Design scales across Factorial.

🧐 What We’re Looking For

You're a perfect fit if...

• You’ve designed products that actually grow — ideally in SaaS or Product-Led Growth environments.

• You solve real problems, not just requirements checkboxes, turning ambiguity into clear solutions.

• You own your work end-to-end — from research and ideation to implementation, iteration, and measurable business outcomes.

• You love experimentation and try out new things — validate designs, iterating on results, and learning what drives user behavior.

• You’re a team player who amplifies others, shares knowledge, and seeks feedback relentlessly.

• You communicate clearly in English, explaining design decisions in both human and business terms.

Extra points if...

• You’ve worked in Product Growth initiatives such as self serve and free trial, customer onboarding, cross-selling…

• You’ve thrived in fast-moving startups or hyper-growth teams in B2B SaaS and are familiar with its dynamics.

• You speak the language of metrics — acquisition, activation, retention, upsell, expansion.

• You measure your design impact, connecting your work to revenue, conversions, or retention.

PS. At Factorial, we don’t care about how many years you’ve worked - we care about what you can do. See a skill you don’t
