PHP CSS LESS SEO CMS Office

Hello!
At Factorial we´re looking for a Full-Stack Senior Software Developer to help us boost the company to the next level.

Ready to be part of the challenge?
Help us move the needle on MRR
At Factorial, the Growth Marketing team is the driving force behind experimentation and innovation to find new distribution channels, optimize our acquisition funnel, and increase the volume and quality of leads. We are also the only technical team in Marketing, supporting over 100 stakeholders across content, SEO, events, partnerships, paid media, and more.
We’re looking for a Senior Developer who can thrive in ambiguity, move fast, and balance high-impact growth experiments with strategic, long-term improvements — like evolving our CMS and scaling our web platform.
The annual salary range for this position is €51,000 to €70,000.
What You’ll Do

- Lead front-end implementation for growth experiments across our marketing website and acquisition funnel — build, test, validate, iterate.

- Modernize our CMS integration (DatoCMS) to support scalable, flexible content structures. You’ll help us evolve away from legacy limitations and enable better workflows for both devs and non-devs.

- Collaborate with Marketing and other teams to bring high-quality, fast-performing, visually compelling pages and campaigns to life — animations, interactions, mobile-first execution.

- Be a multiplier for the team by mentoring developers, advocating for quality, and raising the technical bar through communication, documentation, and reviews. You will partner with another senior developer and be part of a team of mid-level developers and product designers.

- Support internal teams by building reusable components, scalable templates, and internal tooling that allow 100+ stakeholders to operate more efficiently and autonomously.

- Own experiments from code to data: Contribute to defining success metrics, integrate tracking, analyze outcomes, and iterate based on learnings.

- Keep performance top of mind — deliver high Core Web Vitals scores while supporting delightful, creative UI/UX solutions.

You’ll Be a Great Fit If You…

- Thrive in fast-paced, ambiguous environments: You´re energized by change, comfortable prioritizing on the fly, and excited to solve problems that don’t yet have a process.

- Have expert front-end skills: Advanced CSS, responsive layouts, animation libraries (Framer Motion, GSAP), and React/Next.js are your core tools.

- Understand the CMS problem deeply: You’ve worked with large CMS-driven sites (DatoCMS, Contentful, Sanity, etc.), migrated legacy setups, and understand the balance between structure and flexibility.

- Think like a growth manager, build like an engineer: You care about user behavior, performance, analytics, and experiment velocity just as much as you care about clean code. Over time you should have a value in bigger picture aspects such as business overview + technical aspects.

- Communicate clearly across functions: You can talk to designers, marketers, and backend engineers — and make everyone feel heard and aligned.

- Mentor others: You’re happy to help less experienced teammates grow. You value good documentation, constructive feedback, and leading by example.

- Have a “get it done” attitude: You´re not afraid to get scrappy, patch something fast, or prototype to validate a hypothesis.

Bonus Skills

- Experience working on design systems or refactoring one

- Familiarity with backend at least in a middle level (Rails, PHP, or any CMS templating system)

- WebGL, Canvas, or advanced creative coding experience

- Familiarity with data analysis, A/B testing tools (e.g., Google Optimize, Segment, Amplitude)

Regardless of these requirements, we encourage you to apply if you are interested in the position. The list above it´s just a starting point of our conversations, but that doesn´t mean we won´t hire you if you don´t have one of the skills. We hire for talent.
Why You’ll Love Working Here

- Work in a cross-functional Growth team where experimentation is not a buzzword — it’s how we operate.

- Own projects from idea to shipped, with the freedom to propose, validate, and measure.

- Collaborate with designers, marketers, and content creators at a high-growth, product-led company.

- Join a team that values learning, autonomy, and psychological safety — no blame, no ego, just building great stuff together.

Benefits
We care about people and offer many benefits for employees:

- High growth, multicultural, and friendly environment

- Continuous training and learning based on your needs

- Alan private health insurance

- Healthy life with Wellhub (Gyms, pools, outdoor classes) ♀

- Save expenses with Cobee

- Language classes with Preply

- Get the most out of your salary with Payflow

And when at the office...

- Breakfast in the office and organic fruit

- Nora and ApetEat discounts

- Pet Friendly

At the moment we´re looking for a Backend, Frontend and Mobile Engineers, ideally with previous experience with these technologies.
Work ethics
At Factorial, we know that building a great product means building a great team. We value some key principles that help us thrive together.

- Radical (and Passionate) Candor: We´re excited about creating great products and advancing our mission. This means being proactive, obsessing about quality, and experimenting. We tell our managers and peers things we think we cannot say, practicing radical candor to drive innovation and improvement.

- Effective Communication: Clear communication, especially in writing, is crucial. We communicate openly, build narratives, and aren´t afraid to debate ideas. If we can´t explain something clearly, we seek to understand more deeply until we can. And remember, English is our vehicular language, so you need to be comfortable with it!

- Product Vision: We understand our users´ needs and actively engage with them. We constantly look for business opportunities, always asking "What can be next for Factorial?"

- Reliability and Accountability: We deliver on our commitments while maintaining high quality. We feel accountable for the culture and make others feel accountable too. When we see something broken, we stand up to fix it, feeling responsible for all of Factorial.

- Problem-Solving: We don´t limit ourselves to our nominal job definition. We bring, execute, and later communicate solutions, seeking approval only for decisions that would be hard to reverse.

- Teamwork Ease: We collaborate well, adapt easily, and are open to feedback. We convince or get convinced, asking the same from everyone. If an initiative comes top-down, we debate it until we fully buy-in, then champion it to our teams.

- Fighting Complacency: We challenge the status quo and fight complacency with our whole hearts. We´re vocal when something is going wrong, seeing it as an opportunity for a better world.

- Having Fun: While our work is serious, we trust our gut when we have a 10x motivation to try something new. We jump on opportunities for innovation, involving as many people as possible.

Your first steps in Factorial
You’ll start with a 2 weeks onboarding period, where you will:

- Read a lot: Learn about Factorial, our product, our team, and our clients.

- Learn a lot: Pair with each team member at least once, to understand what they are working on.

- Code a lot: Solve low-stake bug tickets or quick wins.

- Fail a lot: We work with ephemeral development environments with almost zero configuration so you can start coding fast. And failing, going back, retrying… We understand this is part of the path, so, we will encourage you to be brave!

- Talk a lot: Be fully integrated into the team’s rituals from day one.

After your onboarding, your day-by-day work will look like the following:

- You will be a product engineer, taking ownership of big initiatives, and being interested in the outcome, not just the output. About the outcome, you’ll also work with your team members to establish goals and plan a quarterly roadmap, putting special attention to the technical needs of our domain.

- A Senior Engineer at Factorial influences requirements definition and is autonomous in delivering a polished solution that matches those. You participate in the team’s decision through Requests For Comments (RFCs) that you write yourself or read others’.

- You will be involved in customer calls to learn about their pains & needs.

- You will review code daily and get feedback on your code at every pull request, from all team members, including juniors.

- You will learn from the entire team, both on technical topics (performance, architecture…) and core skills, in an environment driven by engineering quality. You will also mentor junior team members and help them learn from your experience.

Benefits
We care about people and offer many benefits for employees:

- Continuous training and learning based on your needs.

- Alan´s private health insurance.

- ♀ Healthy life with Gympass (Gyms, pools, outdoor classes).
