In 5 years of existence, we’ve managed to :

• Make ourselves known as a groundbreaking accounting and financial software for small businesses and their accountants
• Raise a total of €400 millions, including from Sequoia, the famous fund from the Silicon Valley who invested early in companies like Google, Facebook, Airbnb, Stripe, Paypal and much more...
• Grow from 7 cofounders to 1000 happy Pennylaners : we’re now recognized as one of the greatest places to work in France (and also remotely), with a 4.6/5 rating on Glassdoor.
• Build an international environment with more than 25 nationalities, with a strong remote-friendly culture, where 30% of the employees are already working from all parts of Europe
• Earn the trust of thousands of customers and accounting firms and obtain outstanding ratings
• Already more than 900,000 small and medium-sized enterprises (SMEs) and over 6000 accounting firms use Pennylane in France!

Your mission

You will join our Growth Team and work collaboratively with Thomas the growth engineer team lead within the Marketign website squad.

We are looking for a talented full stack software engineer whose main mission will be to

• Global Scaling: Build and refine the infrastructure supporting our internationalization (multi-language, localized user journeys…).
• Intelligent Automation: Design and deploy AI-driven tools and automated workflows to streamline lead acquisition and personalize user experiences at scale.
• Tracking & Insights: Implement and enhance sophisticated visitor tracking systems to turn raw data into actionable growth levers.
• Ecosystem Connectivity: Design and develop robust APIs to ensure seamless data flow between our internal tools and the broader fintech ecosystem.
• High-Velocity Experimentation: Launch needle-moving projects including A/B tests, white-label integrations, predictive lead scoring, and optimized acquisition funnels.
• Performance Optimization: Maintain and push the limits of our public website and registration funnels for peak conversion across all markets.

Who are we looking for ?

• Experience: At least 2+ years of professional experience as a Software Engineer.
• Tech Stack: Mastery of Ruby on Rails. Proficiency in a JS Framework (Vue/Nuxt) is a major plus.
• Efficiency Obsession: You know how to leverage AI tools (LLMs, Copilots, etc.) and automation to move faster and smarter than the average dev.
• Communication: Fluent in French & English (B2/C1). German is a bonus !
• Adaptability: You are energized by an ever-shifting startup environment and love collaborating with diverse stakeholders (Data, Sales, Marketing).

The technologies we use in the Growth Engineering team

Ideally you’ve already got some knowledge with data tools including data tools integration (GTM, Segment) or data visualization (Datastudio, Looker) and you’re familiar with digital marketing (paid acquisition, conversion, SEO…).

What do we do to make your work life easier

• Wherever you are based, you will get 25 vacations days paid by Pennylane
• You’ll have a competitive compensation package
• You’ll get company shares to enjoy a piece of the success story you're building with us
• You’ll have a budget to turn your home into a more comfortable workspace, as well as a monthly allowance to work from a coworking space whenever you feel like it
• Through our partner Gymlib, you’ll have access to 8000 fitness spaces in Europe and more than 300 activities related to wellness
• You’ll have access to Busuu to perfect your English or your French
• You’ll get the latest Apple equipment
• Depending on the teams and the requirements of the position - you'll be able to work remotely from your country of residence, as long as it is in Europe and within a maximum time difference of two hours from the CET time zone
• We are committed to regularly coming together for company events such as Tech Days (which bring remote Pennylaners together every 3 months) or our annual company seminar, fostering significant moments of cohesion for everyone.

If you are based in France, you will have a French contract following French regulation on top of the additional perks : 6 to 12 RTT, 5 weeks PTOs, lunch credits (Swile), Alan Blue healthcare cover and regular events in cities where Pennylaners are mostly presents (Lyon, Bordeaux, Nantes…)

We're working on providing those last advantages to our people based outside of France as well, but it can be quite more complex depending on different countries.

Who are we looking for ?

• To speak English (level is assessed and appreciated according to the department you’re applying to)
• To be energized by an ever-shifting work environment
• To be highly collaborative (within your team or other stakeholders)
• Sufficiently experienced to prioritize business-led actions on your day to day activity

We know that some people are less likely to apply than others, if they don’t feel like they meet the full list of criteria.
