- Lead significant technical deliveries within your squad, from understanding the problem to designing, implementing, testing and operating the solution in production
- Investigate and resolve complex production issues, using monitoring, observability and data analysis tools to identify root causes and prevent recurrence
- Design and evolve robust solutions, identifying performance, scalability and reliability opportunities and turning them into pragmatic technical improvements
- Bring strong expertise in at least one major part of our stack, while being able to join a new team and become autonomous on a high-impact initiative within a few weeks
- Improve engineering practices across the organization, through high-quality code reviews, pair programming, documentation, RFCs and the adoption of AI-assisted development without compromising software quality
- Act as a role model and a driver for other engineers, sharing knowledge, providing actionable feedback and helping the team continuously improve its technical skills and ways of working
- Collaborate effectively with other teams when needed, proactively unblocking technical topics and clearly communicating progress, risks, decisions and results to the relevant stakeholders
- Contribute to the Pennylane tech community, through technical content, onboarding, interviews, incident resolution, tech initiatives, meetups or other community-building activities
The application process
- You will first have a general chat with a Talent Acquisition Manager (30 min)
- You’ll then have a test-home assignment + a debriefing session with two of our software engineers (1 hour)
- You’ll have a last culture-fit discussion with two people from our tech leadership (1 h)
- We make sure we move fast ; you can expect the recruitment process with us to last between 15 and 25 days in total
Benefits
- Work remotely from anywhere in Europe, as long as your contract allows you to
- Company shares to enjoy a piece of the success story you're building with us
- 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
- Access to 8000 fitness spaces in Europe and more than 300 activities related to wellness through our partner Gymlib
- Access to Busuu to perfect your english or your french
- The latest Apple equipment
- Be part of a vibrant social community: we do lots of sports together (running, climbing...), we love to hang out and have a drink together (Thursday afterwork drinks on our rooftop is a usual thing)
- Twice-a-year company seminars

- 10 additional days off (to the 25 standard ones) for those based in France
